hey man i want to ty so much for this series wow honestly ty so much, i was looking to do turbo in my 90 miata and i was overwhelm with options and shocked at the prices for turbo kits and scared of cheap turbos from ebay for i am not a millionare to afford a new motor if i blow mine, so this project as budget turbo is just what i wanted for what i see in forums online is like people are too condesendent to newbies like me when i ask question, and you answer them all spectialy drilling the oil pan, superb work, ty so much, right now im doing suspension kit koni and megasquirt, once thats done and i save more money ill do the turbe. ty from Venezuela and ill try to video what i do and ty personaly for knowlege shared here in UA-cam Univerity lol. congrats on your work.
that silicone hose all squeezed between the radiator and the subframe will get a small hole/slash and make a boost leak. nice videos, you can make it simple to understand even for who barely understands english. cheers
+Bv1nte I'll probably put a couple little pieces of plastic on it to protect it, but it will most likely take a long time to cause any issue. When you have a turbo Miata you always have to check out all the parts and inspect for and damage or issues, I do it on my other car every 1-2 weeks.
I've been just sitting here going through the entire build. Finally understanding how all the parts of the turbo work together (intercooler, wastegate, blowoff valve, etc..). I really want to do a build like this some day when I got some more money lol.
After finally deciding I wanted to run scca I researched the "easiest" and cheapest car to race successfully. I landed on the na miata. I saved for a few months and just aquired a 96na with a t28 running ms v1 with a very conservative tune. I watched most, if not all your miata videos before finally going to buy one.Your content definitely sealed the deal on what I was looking for when I purchased my first miata.
You rock man. I've been following you for a while. I already have Torsen, MS, bigger injectors, Supercharger etc. I'm working on installing an intercooler. So this video really helped. Thanks!
+TheCarPassionChannel Thanks. I ran into the same issue you had with fitting the 2" from the turbo / supercharger and down to the IC. I'm going to remove my AC, so I'm thinking about just removing the fan that is in the way, and use the other one (I have two fans because of AC). What do you think about that?
HellFireno88 I'm thinking about just removing one of the fans, that should clear up enough space where I need it. I really want to keep the a/c just for the resale value.
Man I love how i don't even have a miata and still am so interested in these vids. Wish I lived in cali I would love to be apart of this channel and wrench
good commentary and everything in the video i thought it was very well put together! not a miata guy but its great how you kept the video short, but didn't skip any important things at all. also, mighty car mods has a turbo miata build video somewhere if you want to check it out!

+Ricardo Montana Now P/S and no A/C makes the piping sooooooooooooo easy. Protip - you can replace the crazy stock lower radiator hoses/hardpipe setup with a single 1985 Buick Electra radiator hose to make even more room. (99% sure it's an upper radiator hose but if you go to a parts store and look at one you'll see which one you need. You just cut it to fit.)
also apropriatley sozed intercoolers with give you far less pressure drop due to the interior volume of the intercooler. cant wait to see some dyno results from ur build
First off love your videos, nice to see someone trying to do everything the best way they can. My question is, since you're still running a MAF, why did you decide against recirculating the blow off valve?
+Matthew Ammerman If I have difficulties with it, I'll have to recirc it. For now it's just the easiest solution. Good question though, I'll try to remember to cover that in the part 2 video.
Hey man I've noticed throughout your videos you have some serious lifter tick. there's an easy fix for this. next time you change your oil put some dex 3 in there and the ratio is simple. here's an example approx 3 quarts of oil in the miata put 2 quarts of oil and 1 quart of dex 3. another thing that is just absolutely amazing to run in your miata is Rotella T6 oil. I've owned quite a few miatas and run them all with that na and boosted all year around and I live in Ohio so it can get cold here and it keeps the engine clean and running amazing.
Quality keeps getting better. Great use of inexpensive parts. Since we are in the southwest where temps are often 90's (or in my case 110-120's) and intercooler really is mandatory. I am seriously considering doing an air to water setup for mine. I have had good luck with A/W setups back in my RSW days.
TheCarPassionChannel Do you think an air to water charge cooler would fit? Most are ~4" deep and vary in width and height. But I think a 4"x4" charge cooler could be fit with slim electric fans. That would shorten the plumbing runs a LOT and maybe preserve throttle response? What do you think?
TheCarPassionChannel I have been an engineer too long, lol. I fixed the miata cupholder buy building an entirely custom console from scratch. I'm not very good at simple. :)
NickelNDiminIt I know others of your type, lol. The ATW intercooler is actually seeming like a really good idea now that I think about the fact that you would free up so much airflow to the radiator... got me thinking now!
Ohh man i remember cutting my IC pipes, but i made a bead roller out of a pair of old vise grips !! just had to use a grinder to grind out a notch on the top half of the teeth of it and then weld a little bead on the bottom half and when you clamp it on the welded bead on the vise grip pushes into the notch you cut in the top half and creates actually a pretty decent bead roll. And it didn't cost me a dime ! One recommendation when mountain bov's is preferably you want it closest to the throttle body ( like how Car Passion did ) because that is the first point where surge begins. So the closest you can get the bov to the throttle body the less likely you are to experience surge at the compressor wheel.
Bigger piping is also more volume to have to compress and can increase lag, if it's big enough, not going to be an issue with that cute little cooler but with something like my RB25 running 600 x 300 x 80 intercooler large piping can start to cause an issue.
I wonder if heating plastic pipe, balloon it with air pressure, then flatten an shape to better snake through tight spots. Thinking of it as same air flow capable just friendlier dimensions. Eample, 2 1/2 inch pipe formed to 1/2 inch by 6 inch wide (guessing) to sweep over radiator under hood then forms back to the 2 1/2. Point of this question is can the pipe dimensions be altered to equal or greater and still have same result?
Thank yoy for the so much nice information. please tell me is it better to use more metal tube-pipes than silicon connections? i mean, at a silicon elbow is it better to use a metal pipe?
@TheCarPassionChannel - Have you seen a driverside fender route for the 2.5" piping, if so what are your thoughts? PITA? can you keep the Fender liners? Love your STREET CRED!
+Troy Sebo Yeah I've seen it, I just didn't want to hack any holes in the car. On part 2 of this video, I have a slight revision for the piping routing.
@thecarpassionchannel you need to recirculate the BOV with stock ecu/air flow meter. Air is getting measured going into the system but then leaves when vented to atmosphere. causing car to run rich
+TheCarPassionChannel I figured you knew, but being rich wont rly hurt anything. unless it causes a misfire or a bog i guess. good luck with the rest of the build tho!
rstormzand Yeah it can cause noticeable power loss between shifts for sure. I might en up piping it in when I'm tuning it, it just depends how bad it is. It will be my first time doing this with the stock ECU so it will be a learning process for sure.
TheCarPassionChannel i had my turbo miata on the stock ecu last year with aem fic. its pretty good but i could never get the transition from vacuum into boost just right and it would occasionally misfire. what piggyback will you be using?
you really should leave more of a gap between two peices of pipe connected by a silicone joiner. They need space to move about and flex and it also prevents the ends of the pipe from grinding against each other
A suggestion for saving room, might ad $30-$40 to the budget, but used that coolant reroute video for inspiration. If you want to still use the stock radiator, you can buy those thin 10”-12” fans. Stock fans (mainly the supports) are quite big and cause issues as this video presented
Wow!!! You are using the stock air box on this turbo build??? I'm getting really curious on what ECU and tuning method you are going to use. This is some great stuff.
I was under the impression that a bov/ bpv wasn't required for low boost aka under 8psi, and that the increased wear and potential damage that is caused by compressor surge is mostly for higher boost applications.
+TheCarPassionChannel o for sure. I tried to fit a ebay BOV on my miata, but it kept leaking and not working well enough so I just tossed it. Eventually I will be putting a name brand BOV on there. I just finished my budget miata build all in with megasquirt it was 1500 total. Loving it so far, and loving your build!
I was wondering if most of the parts youve used will work on a 1.8 obviously with some variations on where the engines are differnet but is size and fitmit will most things fit?
90% of them from an Ebay kit that was around $80 for all the piping, couplers, and clamps. Some individual ones can be found on Ebay for pretty cheap, and if you need a specialty sized one hit up siliconeintakes dot com.
recently sold my NA but im coming back to the country and i want to buy another NA but good ones are hard to find so im thinking about getting an NB.. do u know of a channel like yours but works on NB's instead? btw love your channel
+s Haha not really sure of another channel like mine for NB's, but quite a bit of what I cover will work for NB's as well. OR at least serve as a good guideline.
I thought the blow off valve also determined the boost level, like if you have a 10psi spring the bov would open the valve to release some boost if it exceeds that. If thats not the case how do you control boost? sorry if this is a stupid question.
+mason soileau No such thing as a stupid question, people get that confused all the time. The boost level is actually controlled by the wastegate inside the exhaust housing of the turbocharger. When the boost gets to a certain level, the gate opens up and lets the extra exhaust gasses around the turbine wheel so it doesn't spin too fast. The blow off valve is designed to release the extra boost pressure from the intake piping when you let off the throttle and it has nowhere to go (you don't want it to get forced back into the turbocharger). If you check out Ep. 4.1: Internal Wastegate Porting it might give you a better understanding of how the wastegate works.
+Kykle Nah I don't even have one on my 250whp car. I will set on up when I swap the head in a few weeks though. On a lower power build I'd just recommend a 323 GTX PCV valve from Fab9Tuning.
thoughts on the cx racing diy kits? i read that there turbo kits are not so great, but haven't read anything on their inter-coolers. On one of your videos you had a cs racing inter cooler. so what are your thoughts?
+Classified Recon I would totally run their intercooler kit. IC's and piping are so simple they're hard to mess up, plus it's not like they're exposed to a lot of heat like a manifold.
I've been looking alot into miatas more or less because we'll they're cheap and form what I hear extremely fun rwd cars, I currently have a 2002 acura rsx and my biggest concern is me fitting in a miata, so I figured I'd just ask now you think me being 6'1" and 250 is to big for a miata? I've been reading alot about the "foamectomy" and bolting to the floor and such but if possible I'd like to keep stock seat rails. lol long questions but I'd like an answer from somone that isn't from a 8 year old forum
+Casey Wise Honestly the best option is probably going to be a complete aftermarket setup with a bucket seat with an aftermarket mounting setup, that will give you both headroom and legroom. Putting a bucket on the stock rails works, but it's hard to make the seat sit lower. I would try to drive a completely stock Miata first and see how it is, the foamectomy will sit you about an inch lower (I used to have it before I went to a bucket seat. I'm 5'10" and I have plenty of headroom. The NC might have a little more room inside since it's bigger so you might want to consider those too, but I know plenty of people that are 6'2"/6'3" driving Miatas, it's all about the seat setup.
+mason soileau Thanks! For the piping and BOV, you literally just search ebay for "intercooler piping" or "blow off valve" and you'll see the exact parts I'm using in the first couple pages.
Alright, so as far as intercooler placement on a Miata goes it's pretty much a no brainer that it goes into the "smile". But here's my question: if you're going boosted and not upgrading your cooling isn't the heat from the intercooler going to diminish the efficiency of your radiator, potentially causing engine overheat? That's the one thing I still can't wrap my head around with Miata boost builds.
+Totally Legit Gaming [TLEG] Not only the heat from the intercooler, but it also blocks the airflow to the radiator. Keeping turbo cars cool is a constant battle! For street driving it's usually not a big deal but at the track, temps get high fast if your cooling system isn't in order.
+TheCarPassionChannel Right, so it's like I thought. So for a track car you'd place the intercooler someplace else, or even go water-to-air and place it's radiator someplace else?
hey question that fitting you use is the exact size you needed for the hose because Ima about to order one but not sure . ALSO WHERE DO YOU ORDER YOUR FITTINGS FROM STILL LOOKING FOR THE ONE FOR THE OIL PAN PLEASE LET ME KNOW THANKS
+TheCarPassionChannel my question is the fitting you used for the intercooler next to the throttle body where did you get it from . Also where did you get the one for the oil pan to been looking for it can't find if you really want can you please email me the links of each fitting I only need this for my turbo set up my email is diazanthony300ex@gmail.com please email me them thanks
hey man quick question if you're not going to run and ECU how are you going to prevent the mass air flow sensor from sensing boost... I might be a bit confused on this topic
+luis moreno I don't really have to worry about the AFM, I think it pretty much maxes out and then you control the fueling with rising fuel pressure in boost. You do need to trick the o2 sensor though, it needs to shut off as soon as it goes into boost. I'll cover that!
Hey I'm grabbing a used t25 turbo from a former 240 owner for $80. Seems like a decent deal, but he does say it has a little shaft play and needs a rebuild. Don't suppose you could take a look at a few pictures and tell me if it looks like it's trashed or not?
+Mathew Brady Yep send em over thecarpassionchannel at gmail dot com. Send clear pictures of the compressor and turbine wheels and a video of the shaft play if possible.
I'm going to install my intercooler not connected to anything, just hanging in the front bumper. Street cred...to lazy to install the rest of the kit lol
how did you get your tire and wheel combo to work with your fenders without flares.... after reading through all the forums, they make it seem like its impossible, im about to order some 15x8 et0 but scared it wont work
+Colman Au Bmx Media 15x8 +0 are more aggressive than my 15x9 +16 setup. I used to run with 15x8 +0, if you want to run a 205/50R15 get ready to spend an entire day on fender work.
Can you link us to the kits you used so we can have an exact price point to work with? Also can you list the exact pipes and cuplers you used to do this?
+Crsp Gngr If you ebay search "intercooler piping" there will be a ton of universal kits on there. I used 8 x 2.5" straight couplers, 4 x 2.5" short aluminum 90's, 2 x 2.5" big aluminum 90's, a 2.0" straight aluminum piece, 2 x silicone 2.0" 90's, and a 2.0-2.5" silicone 45. I recommend checking out siliconeintakes dot com too, their stuff is a littl more expensive than ebay, but the silicone is better quality and you can return all the parts you don't use for a full refund (minus shipping).
+TheCarPassionChannel Do you have measurements for the long/short 90's and the length of the straight pipe?

Crsp Gngr No I don't have any measurements. I'd suggest either buying a universal kit like me, or heading to silconeintakes dot com and buying from there because you can return what you don't use (just pay shipping)
Do you have the bolt sizes/thread types by any chance? Mine didn't come with bolts, and I would feel silly walking around the hardware store with an intercooler under my arm!
+Phillip Glass-Hess (Wingman703) LOL before I read your comment I was going to recommend just bringing the IC to the hardware store. Don't feel silly haha. They're probably M5 or M6 bolts.
Why keep the AFM there? Im guessing you're just going to use a FPR? Unrelated, but for a 1st gen MSPNP, the firmware flashed into the ecu can either be with MAF or without, in addition to the basemap having to be with or without...so essentially you need both firmware and map to be with/without a MAF for it to work properly. Am I right?
+TheCarPassionChannel No no, heres the deal, i got a used mspnp 1 from a turbo 96, which obviously had the GM IAT....when i plugged the ecu into my stock car, even with the basemap loaded, it would start up to 2k rpm, then die....im wondering that is it possible that even though the basemap is for a 96 with MAF, maybe the firmware itself is flashed without the MAF settings? not sure if that even made sense, i just read it on the interwebz refer to comment #12 forum.miata.net/vb/showthread.php?t=495359
speedblazer94 I think he is saying out of the box, the MS is setup to run without the AFM. At any rate, if you just blug in someone elses tune or even a base map, it might need some tweaks to idle properly.
+Josh Vincent Yep that's the word on the street. Too bad it's for a T3/T4 though. A couple people I talk to said they're trying the T3/4 -> T2 adapters with them.
greg if one were to do this build identical and not run an intercooler, and that person were to track day their car at autocross events...would we be adding too much stress to the motor or anything? or just be running too rich? or be fine with no intercooler?
You just want to keep the boost low and the ignition conservative. Even at 5psi, the intake temps can get pretty high. Too much boost + no intercooler = detonation.
@@TheCarPassionChannel air cools as it expands.. so do you think there would be any benefit from running smaller pipe through the actual intercooler itself? Assume you are below .4 mach
@@alikengi17 It will cool as it expands into the intercooler and heat back up an equal amount as it's compressed immediately again into the piping though
@@TheCarPassionChannel precisely, I want it to be in it's heated state through the intercooler and then expand as it enters the throttle body. Maybe results would be negligible.. Also I would love to have a map sensor at the manifold and another pressure sensor near the turbo compressor
It's seems that nobody really knows, my theory is that as long as you maintain your boost target at the manifold, flow through the intercooler system is sufficient, although an open wastegate will reduce exhaust flow restriction. So it's a very difficult line to walk.

Do you think an air to water charge cooler would fit? Most are ~4" deep and vary in width and height. But I think a 4"x4" charge cooler could be fit with slim electric fans. That would shorten the plumbing runs a LOT and maybe preserve throttle response? What do you think?
NickelNDiminIt I've always thought about a water-to-air unit. Air-to-air is just so simple, no water lines or anything external to worry about.

I have been an engineer too long, lol. I fixed the miata cupholder buy building an entirely custom console from scratch. I'm not very good at simple. :)
NickelNDiminIt I know others of your type, lol. The ATW intercooler is actually seeming like a really good idea now that I think about the fact that you would free up so much airflow to the radiator... got me thinking now!
broke and boosted make me laugh and cry in the same time because i'm in same situation :))
Ohh man i remember cutting my IC pipes, but i made a bead roller out of a pair of old vise grips !! just had to use a grinder to grind out a notch on the top half of the teeth of it and then weld a little bead on the bottom half and when you clamp it on the welded bead on the vise grip pushes into the notch you cut in the top half and creates actually a pretty decent bead roll. And it didn't cost me a dime !
One recommendation when mountain bov's is preferably you want it closest to the throttle body ( like how Car Passion did ) because that is the first point where surge begins. So the closest you can get the bov to the throttle body the less likely you are to experience surge at the compressor wheel.
+Review Guy Haha genius idea on the bead roller.
+TheCarPassionChannel thanks !
4:33 hahahaha I frickin love you man
Nice videos bud! Can't wait to turbo my car (: I got almost everything to turbo it. NO A/C lol I live in Arizona
lol where do you live? that mexican music at the end was too funny!
+RUIND I live about 20 minutes from Mexico haha
lolol that explains everything!!
+TheCarPassionChannel You're in Texas?
Evan8D SoCal, San Diego
Hey dude, can you please make a video on what coilovers are the best, and how to install them?
+SGsuck Will be coming some time in late March or so
+TheCarPassionChannel Awesome! I will buy my first car ( Mx-5 NA) tomorrow :D
Thank you Greg this so helpful for the turbo build I'm about to do.Keep it up man👍
Funny outtakes, Greg!😂 Did you see the Turbo Miata build at the Carthrottle- Channel?
+Fuelfoxx I'll have to check it out
cant wait for the finished product!
Hey Greg, can you do the COP install video for standart ecu and ms2?
Bigger piping is also more volume to have to compress and can increase lag, if it's big enough, not going to be an issue with that cute little cooler but with something like my RB25 running 600 x 300 x 80 intercooler large piping can start to cause an issue.
tangles01 clap
I wonder if heating plastic pipe, balloon it with air pressure, then flatten an shape to better snake through tight spots. Thinking of it as same air flow capable just friendlier dimensions. Eample, 2 1/2 inch pipe formed to 1/2 inch by 6 inch wide (guessing) to sweep over radiator under hood then forms back to the 2 1/2. Point of this question is can the pipe dimensions be altered to equal or greater and still have same result?
if i were you i'd consider running washers on the bottom mounting as those bolts are going to end up being pulled through the plastic
So glad I don’t have power steering. In fact why did Mazda bother with PS especially on the earlier models?
good video. I plan on my first gen sc2 soon. getting all the parts first
Keep going mate you're doing well
Thank yoy for the so much nice information. please tell me is it better to use more metal tube-pipes than silicon connections? i mean, at a silicon elbow is it better to use a metal pipe?
you should do a video on installing a coolant reroute.
+Alec Parkes I have many requests for this, definitely a future video.
Please never stop making videos...
as Regular car reviews would say "air goes in one turbo and air goes in another turbo and makes BIGGER AIRRRR"
@TheCarPassionChannel - Have you seen a driverside fender route for the 2.5" piping, if so what are your thoughts? PITA? can you keep the Fender liners?
Love your STREET CRED!
+Troy Sebo Yeah I've seen it, I just didn't want to hack any holes in the car. On part 2 of this video, I have a slight revision for the piping routing.
might be an idea to stick within your budget and make a home brew water sprayer to cool the charged air :P
@thecarpassionchannel you need to recirculate the BOV with stock ecu/air flow meter. Air is getting measured going into the system but then leaves when vented to atmosphere. causing car to run rich
+rstormzand Yep I know, will address it if it becomes an issue.
+TheCarPassionChannel I figured you knew, but being rich wont rly hurt anything. unless it causes a misfire or a bog i guess. good luck with the rest of the build tho!
rstormzand Yeah it can cause noticeable power loss between shifts for sure. I might en up piping it in when I'm tuning it, it just depends how bad it is. It will be my first time doing this with the stock ECU so it will be a learning process for sure.
TheCarPassionChannel i had my turbo miata on the stock ecu last year with aem fic. its pretty good but i could never get the transition from vacuum into boost just right and it would occasionally misfire. what piggyback will you be using?
rstormzand Were you using any sort of o2 sensor signal modifier?
Hello! Excellent video ... I would like to know what dimensions has that intercooler?
still deciding if I should keep power steering and AC or if I shouldn't take them out, hmm...
you really should leave more of a gap between two peices of pipe connected by a silicone joiner. They need space to move about and flex and it also prevents the ends of the pipe from grinding against each other
Hey Man! When is episode 8 coming???? Keep It Up!
A suggestion for saving room, might ad $30-$40 to the budget, but used that coolant reroute video for inspiration. If you want to still use the stock radiator, you can buy those thin 10”-12” fans. Stock fans (mainly the supports) are quite big and cause issues as this video presented
I find it hard to believe that an intercooler is needed and that it even does anything... but it totally does :P
You should see intake temps with and without an intercooler. An intercooler can easily lower them by 100+ degrees F.
Hey Greg! How is the Freddy Blow-Off Valve working with Broke and Boosted? Are you happy with its operation?
I ended up not using it, it leaked so bad right out of the box. I talked about it in ep14 I think. No problems thus far running no BOV though.
Wow!!! You are using the stock air box on this turbo build??? I'm getting really curious on what ECU and tuning method you are going to use. This is some great stuff.
+boaz ovilma Stock AFM, but not the stock airbox. It's my first time tuning thing was so it will be a learning experience.
These vids are gold
I was under the impression that a bov/ bpv wasn't required for low boost aka under 8psi, and that the increased wear and potential damage that is caused by compressor surge is mostly for higher boost applications.
+George Lamontagne I like to be safe rather than sorry, it definitely won't hurt to have it.
+TheCarPassionChannel o for sure. I tried to fit a ebay BOV on my miata, but it kept leaking and not working well enough so I just tossed it. Eventually I will be putting a name brand BOV on there. I just finished my budget miata build all in with megasquirt it was 1500 total. Loving it so far, and loving your build!
I was wondering if most of the parts youve used will work on a 1.8 obviously with some variations on where the engines are differnet but is size and fitmit will most things fit?
Yeah turbocharging the 1.8 and 1.6 are almost identical. The main differences are the manifold and oil feed line.
Where did you get your couplers? Those things are expensive and I'm looking for some cheap(er) silicon ones.
90% of them from an Ebay kit that was around $80 for all the piping, couplers, and clamps. Some individual ones can be found on Ebay for pretty cheap, and if you need a specialty sized one hit up siliconeintakes dot com.
recently sold my NA but im coming back to the country and i want to buy another NA but good ones are hard to find so im thinking about getting an NB.. do u know of a channel like yours but works on NB's instead?
btw love your channel
+s Haha not really sure of another channel like mine for NB's, but quite a bit of what I cover will work for NB's as well. OR at least serve as a good guideline.
I thought the blow off valve also determined the boost level, like if you have a 10psi spring the bov would open the valve to release some boost if it exceeds that. If thats not the case how do you control boost? sorry if this is a stupid question.
+mason soileau No such thing as a stupid question, people get that confused all the time. The boost level is actually controlled by the wastegate inside the exhaust housing of the turbocharger. When the boost gets to a certain level, the gate opens up and lets the extra exhaust gasses around the turbine wheel so it doesn't spin too fast. The blow off valve is designed to release the extra boost pressure from the intake piping when you let off the throttle and it has nowhere to go (you don't want it to get forced back into the turbocharger). If you check out Ep. 4.1: Internal Wastegate Porting it might give you a better understanding of how the wastegate works.
thanks for the awesome explanation im gona go watch 4.1! i got my first miata to get good gas mileage for college and i am so in love with it.
I know that it's going to be a low boost build but are you going to do any sort of oil catch can?
+Kykle Nah I don't even have one on my 250whp car. I will set on up when I swap the head in a few weeks though. On a lower power build I'd just recommend a 323 GTX PCV valve from Fab9Tuning.
Could you explain more in depth about the breather filter? A google brought up some confusing stuff.
+Eric Schatz What breather filter? I don't remember exactly what I said
You actually ended up doing so in a later video. I believe Intercooler Pt. 2.
thoughts on the cx racing diy kits? i read that there turbo kits are not so great, but haven't read anything on their inter-coolers. On one of your videos you had a cs racing inter cooler. so what are your thoughts?
+Classified Recon I would totally run their intercooler kit. IC's and piping are so simple they're hard to mess up, plus it's not like they're exposed to a lot of heat like a manifold.
any plans for future mountain battles? Also Thank you for this series, I've been contemplating boosting my miata for a year now.
+TheJoshuarainey5 I don't really like to post them anymore, too much flak in the comments about how I need to 'take it to the track'
+TheCarPassionChannel understandable, well Maybe look into making another series for auto crossing. I enjoyed watching you run that miata.
TheJoshuarainey5 For sure!
hey greg, B&B is using stock injectors with the rising rate fuel reg correct?
+Nick Racicot Yep
very informative, with humor throw in!
Perfect broke video for me😊😊
I've been looking alot into miatas more or less because we'll they're cheap and form what I hear extremely fun rwd cars, I currently have a 2002 acura rsx and my biggest concern is me fitting in a miata, so I figured I'd just ask now you think me being 6'1" and 250 is to big for a miata? I've been reading alot about the "foamectomy" and bolting to the floor and such but if possible I'd like to keep stock seat rails.
lol long questions but I'd like an answer from somone that isn't from a 8 year old forum
+Casey Wise Honestly the best option is probably going to be a complete aftermarket setup with a bucket seat with an aftermarket mounting setup, that will give you both headroom and legroom. Putting a bucket on the stock rails works, but it's hard to make the seat sit lower. I would try to drive a completely stock Miata first and see how it is, the foamectomy will sit you about an inch lower (I used to have it before I went to a bucket seat. I'm 5'10" and I have plenty of headroom. The NC might have a little more room inside since it's bigger so you might want to consider those too, but I know plenty of people that are 6'2"/6'3" driving Miatas, it's all about the seat setup.
Could you possibly link the items you used for this? I am pricing a turbo build and I can't find a kit that has all of the piping you used.
How should I route the vacuum line for the iscv? I have an ms3, would you block off the line, make a bung? I can't find any other info, thanks
where did you get the BOV & piping?
Can you put a link or brand for all the parts you are using? Thanks, I love the videos by the way!
+mason soileau Thanks! For the piping and BOV, you literally just search ebay for "intercooler piping" or "blow off valve" and you'll see the exact parts I'm using in the first couple pages.
Alright, so as far as intercooler placement on a Miata goes it's pretty much a no brainer that it goes into the "smile". But here's my question: if you're going boosted and not upgrading your cooling isn't the heat from the intercooler going to diminish the efficiency of your radiator, potentially causing engine overheat?
That's the one thing I still can't wrap my head around with Miata boost builds.
+Totally Legit Gaming [TLEG] Not only the heat from the intercooler, but it also blocks the airflow to the radiator. Keeping turbo cars cool is a constant battle! For street driving it's usually not a big deal but at the track, temps get high fast if your cooling system isn't in order.
+TheCarPassionChannel Right, so it's like I thought. So for a track car you'd place the intercooler someplace else, or even go water-to-air and place it's radiator someplace else?
hey question that fitting you use is the exact size you needed for the hose because Ima about to order one but not sure . ALSO WHERE DO YOU ORDER YOUR FITTINGS FROM STILL LOOKING FOR THE ONE FOR THE OIL PAN PLEASE LET ME KNOW THANKS
+Anthony Diaz I get pretty much all of the fittings from eBay and Amazon. What's your first question again?
+TheCarPassionChannel my question is the fitting you used for the intercooler next to the throttle body where did you get it from . Also where did you get the one for the oil pan to been looking for it can't find if you really want can you please email me the links of each fitting I only need this for my turbo set up my email is diazanthony300ex@gmail.com please email me them thanks
hey man quick question if you're not going to run and ECU how are you going to prevent the mass air flow sensor from sensing boost... I might be a bit confused on this topic
+luis moreno I don't really have to worry about the AFM, I think it pretty much maxes out and then you control the fueling with rising fuel pressure in boost. You do need to trick the o2 sensor though, it needs to shut off as soon as it goes into boost. I'll cover that!
My flyin miata kit should be shipping today cant wait!
Voodoo 2 or FM2?
+Aidan Morris Pretty much FM2 without electronics. I bought the custom spec turbo kit from them
+Stratospheric Pretty much the best option out there, the FM + MS + Garrett.
+TheCarPassionChannel Yeah, im hoping to run 230ish hp. I just hope the engine will take it as well as yours.
+Stratospheric are you gonna be putting in a new diff?
How about making a boost leak test video after Part 2?
+MrTexxxy I like your thinking
Good video. But... the larger the tubing and intercooler, the more volume the turbo has to fill before feeding pressure to the manifold/cylinders.
Can you do a how to install Manual boost controller please
Hey I'm grabbing a used t25 turbo from a former 240 owner for $80. Seems like a decent deal, but he does say it has a little shaft play and needs a rebuild. Don't suppose you could take a look at a few pictures and tell me if it looks like it's trashed or not?
+Mathew Brady Yep send em over thecarpassionchannel at gmail dot com. Send clear pictures of the compressor and turbine wheels and a video of the shaft play if possible.
+TheCarPassionChannel Just sent an email with pictures. Thanks!
I'm going to install my intercooler not connected to anything, just hanging in the front bumper. Street cred...to lazy to install the rest of the kit lol
how did you get your tire and wheel combo to work with your fenders without flares.... after reading through all the forums, they make it seem like its impossible, im about to order some 15x8 et0 but scared it wont work
+Colman Au Bmx Media 15x8 +0 are more aggressive than my 15x9 +16 setup. I used to run with 15x8 +0, if you want to run a 205/50R15 get ready to spend an entire day on fender work.
aha, i was going for 195/50/r15 , but yea, ill be ready aha
Can you link us to the kits you used so we can have an exact price point to work with?
Also can you list the exact pipes and cuplers you used to do this?
+Crsp Gngr If you ebay search "intercooler piping" there will be a ton of universal kits on there. I used 8 x 2.5" straight couplers, 4 x 2.5" short aluminum 90's, 2 x 2.5" big aluminum 90's, a 2.0" straight aluminum piece, 2 x silicone 2.0" 90's, and a 2.0-2.5" silicone 45. I recommend checking out siliconeintakes dot com too, their stuff is a littl more expensive than ebay, but the silicone is better quality and you can return all the parts you don't use for a full refund (minus shipping).
+TheCarPassionChannel thanks so much for this info man. i appreciate it like you wouldn't believe.
+TheCarPassionChannel
Do you have measurements for the long/short 90's and the length of the straight pipe?
Will these work or do you have suggestions on other pipes?

can you make a vid on the hoses and wires
Do you have the bolt sizes/thread types by any chance? Mine didn't come with bolts, and I would feel silly walking around the hardware store with an intercooler under my arm!
+Phillip Glass-Hess (Wingman703) LOL before I read your comment I was going to recommend just bringing the IC to the hardware store. Don't feel silly haha. They're probably M5 or M6 bolts.
Why keep the AFM there? Im guessing you're just going to use a FPR?
Unrelated, but for a 1st gen MSPNP, the firmware flashed into the ecu can either be with MAF or without, in addition to the basemap having to be with or without...so essentially you need both firmware and map to be with/without a MAF for it to work properly. Am I right?
+speedblazer94 Are you asking if you need to use the MAP sensor regardless of if the MAF is in place? I'm keeping the AFM because the stock needs it.
+TheCarPassionChannel No no, heres the deal, i got a used mspnp 1 from a turbo 96, which obviously had the GM IAT....when i plugged the ecu into my stock car, even with the basemap loaded, it would start up to 2k rpm, then die....im wondering that is it possible that even though the basemap is for a 96 with MAF, maybe the firmware itself is flashed without the MAF settings? not sure if that even made sense, i just read it on the interwebz
refer to comment #12
forum.miata.net/vb/showthread.php?t=495359
speedblazer94 I think he is saying out of the box, the MS is setup to run without the AFM. At any rate, if you just blug in someone elses tune or even a base map, it might need some tweaks to idle properly.
yeah i understand some tweaking is necessary, just didnt realize that it wouldnt even idle at all.
Just FYI, I heard the 1.6 cast manifolds are back on ebay!
+Josh Vincent Yep that's the word on the street. Too bad it's for a T3/T4 though. A couple people I talk to said they're trying the T3/4 -> T2 adapters with them.
+TheCarPassionChannel Just a heads up, I know your struggling to stay within the $1k budget. Keep up the good work, love the videos!
Josh Vincent If that manifold would have been available before I committed to the DIY manifold I would have gone for it for sure though. Thanks!
I take it you live on a busy street? Keep up the videos man, good stuff!
greg if one were to do this build identical and not run an intercooler, and that person were to track day their car at autocross events...would we be adding too much stress to the motor or anything? or just be running too rich? or be fine with no intercooler?
You just want to keep the boost low and the ignition conservative. Even at 5psi, the intake temps can get pretty high. Too much boost + no intercooler = detonation.
So if you are running a megasquirt you can just straight up delete the afm and the idle speed control valve?
+AMC Casares Yes. Highly recommend deleting the AFM, but if you delete the ISCV and AV the idle is harder to tune, especially on cold start.
I don't know if someone asked this question already but what about Smog, will it pass it or not when you turbo the Miata.
Big intercooler + small pipes = ideal. Quicker spool due to less volume and slow air velocity through the intercooler itself
Intercooler system volume does not notably affect lag, very common misconception.
@@TheCarPassionChannel air cools as it expands.. so do you think there would be any benefit from running smaller pipe through the actual intercooler itself? Assume you are below .4 mach
@@alikengi17 It will cool as it expands into the intercooler and heat back up an equal amount as it's compressed immediately again into the piping though
@@TheCarPassionChannel precisely, I want it to be in it's heated state through the intercooler and then expand as it enters the throttle body. Maybe results would be negligible.. Also I would love to have a map sensor at the manifold and another pressure sensor near the turbo compressor
It's seems that nobody really knows, my theory is that as long as you maintain your boost target at the manifold, flow through the intercooler system is sufficient, although an open wastegate will reduce exhaust flow restriction. So it's a very difficult line to walk.
