Galant mod list: vr4.turbomirage...
I really enjoyed watching this! I just got my Galant back Sunday before leaving for Georgia from someone who tried to steal it from me. Dyno tuning is so necessary. Your Galant is making absurd power at 16PSI. The intake manifold is not the weak point. You won't need to replace it until you're making well over 500, and you probably know it's not the manifold installation that's a problem. The real pain is relocating everything bolted on the firewall and manifold. Installing a Magnus intake manifold cost me an additional $1,300 on my GSX for battery relocation, COP ignition and a CID box to do it right. Replace injectors or bump your fuel pressure up in the meantime if you have to, but you'll find that until you're running a turbo that can move enough air to beat 500+ that there is no gain as the manifold is not the weak link.
If you want the viper kart to be fast, please ensure you maintain the traction control features, or build a ballast system where you can add hundreds of pounds of weights as necessary for ballast. I can't imagine a viper kart would have any traction at all. A viper already has a ton of traction issues with the TCS disabled. Matt Farah will attest to this.
Hey Jafro, just the madatory question: When is the next episode coming up? :)
get to work.... you're slower than Tom putting out videos
Sorry to hear about the theft, it sucks both for me and you. Love watching your videos.
Don't worry, it's back! :) Seeing this video makes me want to give it some love.
I cant agree more with this. Tuning is all about shifting the weak point around.
*Here to talk you into replacing that stock intake mani :)*
I mean, a magnus cast manifold wouldn't be "that" flashy. :)
Bigger injectors, new intake... And definitely a viper cart!!!
Surprise project sleeper video. It’s a thanksgiving miracle.
Add an intake manifold so you can make proper use of that head and cams. Then injectors and retune.
Do it man.
I use to ride around in a 360 whp galant. I think people are so use to all the high horsepower builds anymore on youtube that they think 360hp is nothing. 360 whp is still a lot of power out of a 4g63. I'm sure it's a quick car. Good job!
I had a similar setup on my 91Talon TSI, differences being FP green turbo and FIC 1000cc injectors. 368awhp 338awtq 25psi on a 140k original motor, same Old school HK$ 272's and original ETS 4"core Race intercooler. I loved how fast yet reliable and drivable it was. Only took it to the track once and and consistently ran 12.5's at 110-118mph just hot lapping the poor thing! That was with babying it out of the hole so I didn't break anything. So much fun! Nice job Tom! love your work man!
Build a Viper-cart!!
Karts are fucking dumb.
First pull: 241whp. Ok, heartbreaker dyno...
Second pull: 314whp. Holy shit! "Now let's turn up the boost." (picking myself up off the floor...)
Tom, I shouldn't have been surprised, but I was surprised :D
Tom, every time you show the Galant you make me want to go find my own. Love it.
Good numbers Tom, glad to see it back in action. Next you should give us another v-box test, compare it to the original setup.
Thanks Tom for keeping this Vr4 in top condition and on the street with stock(sleeper) look. There is two Vr4's on Tube - yours and the other is mr. J*'s one.
Awesome power Tom! That thing has to surprise some people...
350+ whp in a 3200lb sleeper is super sweet. Always love your vids, sir!
Great video Tom! I really enjoyed it. What's next for the Galant? I'd recommend a set of injectors, obviously. Tim Jilg at FIC takes very good care of me. Tell him I sent you! As far as the intake goes, I'm still on a stock intake on my Talon, and you know a little about it's performance. I do have some 1000cc Hi-Z injectors, but I'm also running E85. Not sure how accessible E85 is to you, but I absolutely love it. I also have a Wally 450 in the tank. the 1000cc injectors barely get me by at a whopping 60 psi base fuel pressure. Here is something I'd like to try though. An Extrude Honed 1g intake. Then you don't have the other incurred costs and other logistical issues. That's my 3.5 cents!
I really really love your galant. I’d love to be the owner of something so well built and clean. It’s such a sleeper too.
Love this one, close to 400 at the wheel , through AWD, that's no small number.
Um, intake manifold/big injectors/big pump please?
Hello from 1722/2k! You know the fire car? Tom, do an intake mani and a bigger turbo already, that engine is good to 9k and you know it! Thought about a BEP bolt on HX40? Thing would crack 500whp but still have great response for the street with good spool! On my new build this year I did an edelbrock victor X intake on a 2G head, and OMG the response with the long runners is ridiculous!! It doesnt have the top end that a magnus or JMF does, but its a street car and way more fun, plus Im still single plate clutch and I think we all know those cant shift up high. Anyways I think just like we all do, your original goal and therefor fuel parts are getting outgrown by the overlooming horsepower bug. Throw in a walbro 450/injectors and lets see some power!! (oh you'll need a 4 bolt rear then too lol)
Tom I know the previous owner of that Viper you were looking at. I live in Baytown Texas and which is next to Channelview. Which is where that Viper is located. He lost that car to the Flooding from Hurricane Harvey and I lost my 2016 Dodge Challenger ScatPack.

Why don't people put their super fancy cars in little boat sheds that float or whatever?
Just put a roof on a floor that floats a few feet around and your car will be clean & dry.
Jay Edlington most of us down here didn't think we were going to flood. I personally do not live in a flood zone. My house is 30 feet above the creek. What got most people down here is that the lakes north of us decided to open their spill ways up at the last minute to their maximum capacity and sent to much water for the creeks to handle. My house was flooded 2 days after the storm passed.
I cant believe you really pulled almost 400hp from that! :O .. Its funny how I stumbled upon this channel as I am just in the market for VR4 galant (that perhaps answers my own question) but the LUCK that you were just doing this project :D Great work!
Today I'm thankful for another TTG video
One of my dream builds would be a '90-'92 VW GTI with a supercharged 3.2 VR6 swap (or 1.8t, can't decide or maybe a G60 16v build) with a 2002 Cabrio dash/interior swap with plaid inserts and headliner with an ever so slightly off white very wet looking paint job. Single round headlight grill and an Audi sunroof swap. The wheels would be BBS deep dish RM's or RS's, black with body color matched wheel lips. Lowered, but none of that lame "stanced" crap. I would even like it to possibly be a '90-'92 GLI.
Next would be an BMW E30 2 door. There are way too many ways I could go with that one too.
I LOVE the feel and driving experience of a great mid 80's to early 90's German car. There is something magical about the way they drive. You throw in a modern day engine for power and reliability and you get the experience of old coupled with the power and driveability of new(er)......
Dooo it Tom! Intake manifold + BIGGER INJECTORS + more boost = MOOOORE POWAAAA! (you know you want to) 😜
I made 26ibs/min on a stock turbo @ 13psi on 560cc Densos, Put on a Gen1 Magnus and now I'm trapped @ 92% duty cycle and 5k rpm flowing 35ibs/min. Larger injectors and an Intake would really make the Galant roar at higher Rpms Tom
Woo hoo go the the mighty galant vr4.
Congrats tom.
I always look forward to watching your videos.
Keep up the good work.
Never seen an AWD dyno before. Super interesting to know the different aspects of the tune also!
I would kill for this car Tom when watching for years and I wish I had the patience you have lol...
Also, a bigger turbo would help that top end drop off and more cfm with less boost = more hp lol
I would at least port match the intake manifold to the head and throttle body and grind down cast marks... I know others would love to see you do a video on that!!!!
I'd probably leave it as is and get another project going. This is a sick sleeper DD and the power levels are insane for the street considering All Wheel power in a ~3200 pound car.
Man, gotta love those 68HTA turbos! Great numbers.
Thanks Jeffrey!
As far as the intake manifold goes "do it do it do it" hahaha, great video as always .
Making 350+RWHP is no joke. That's more than my 5.3L LS swapped Cougar!!! Should be good for some easy low 12 second times slips...
INJECTORS + MANIFOLD + BOOST = VIEWS
I wish I would have been here to talk you into replacing the intake manifold. By the way it's been Tom's turbo garage binge watching day.
Dang, you don't really start cooking until the 4500-5000 range. I have a GT2871r setup on my Speed 3, but my powerband puts down significantly more power much sooner, carrying it all the way to readline (390/385 @ the wheels). I could have even more power sooner, but we neutered it down low for rods' safety.
Why do you think it takes that long into the powerband to make that power? How many lbs/min does that turbo flow? Mine's about 43 or so, and is a great combo for around-town responsiveness, with "guts" over a very wide powerband/tons of power under the curve, yet even flow capacity to be amazing on the highway too.
Anyways, great vid!
I really enjoyed watching the whole episodes... very nice!
Dont stop the street sleeper bulid short , it deserves to hit the 400+hp at the wheels
Great to see it on the dyno! Nice power and that curve is really consistent as well! Now that you've told us how it pulls on the street, how about you show us? OH, and +1 vote for that fuel/intake upgrade!
Listen, you're doing the injectors and the intake manifold thing. Yes, indeed ;)
Awesome video! I'd love to see some in car pulls on the street. Keep up the good work!
I've only been there a couple of times, but as soon as I saw that dyno in the thumbnail, I knew it was Fastech.
Holy Sleeper Batman! Thats some fantastic numbers.
Awesome vid, thanks! I agree with Jafro, don’t worry about the IM with that small turbo; install a 2g fpr
I love your videos man I follow all your steps to work on my 92’ vr4 i hope my car will get to 450hp my next spring! Waiting to see your new viper
An aftermarket or custom intake manifold will be overkill for your goals Tom. Put in a set of modern injectors like ID1050x and retune.
Sweet :) Always a great day when Tom uploads!
How about taking a spare stock manifold, cutting it open, port it from the inside out and have it welded back together, clean it up, perhaps fit a bigger throttle body and you'll be able to keep the sleeper look with an increase in performance. I've seen this method used before and perhaps it would also work for you
Nice! Another intake manifold would definitely add to the motor's efficiency and you can't go wrong with more efficiency!
Nice numbers! I've got four Injector Dynamics ID1050X injectors with a couple hundred miles on them if you're interested. Nothing wrong with them, just went a different direction.
Love your uploads tom, for me it reminds me of watching Motorweek and Stacy David growing up!
What an awesome street car, love your Galant Tom! 14 years on that BR block? WOW! Curious to see what a compression test would look like 💪
port and polish the factory intake manifold surly theirs got to be improvements in it or even filling sections for better flow
The power dropping off probably isn't the intake manifold but due to the exhaust side of the turbo being to small. You may have to much back pressure. You usually want your back pressure to at least half of the boost pressure.
Nice one Tom! I think you should get a better intake manifold. Seeing you have no e85 available. More the air coming through the better the bang and the cars life span to be reliable! 350hp is a safe level.
This is an awesome build, and an awesome video! Get some injectors for sure. Just to add some reliability.
Very healthy figures! Keep it like this for daily commute 😄
Tom you know that it makes sense to upgrade the intake
Do It!!! The intake manifold that is. YES the vipercart would rock
Love the Galant!!! Port that manifold😁 keep it stock looking but add the power up top!!! 👍 love the garage and the videos. Great work as always!
great work Tom, Hp number are looow imo. I was thinking more like 450+ DD.... FYI that intake isan't holding you back, not till ike 600whp would I worry bout that intake. I'm making 700chp with a stock intake, rail, and TB.
I think for the set up you have that size of turbo and intake you got good number tom thank you for share
Nice car Tom. Really it is.
Many unicorns coming out the back of this mad car!
Swap the intake and upgrade the turbo for a big twinscroll! They provide the response and spool of a medium turbo but give a kick at the high end like a big turbo.
DO IT ALL the intake mani and PLEASE build that viper cart it would be so Awsome.
Yes. Go to the darkside, start to replace stock parts. Make the gallant a super sleeper
Awesome episode tom
This is a really solid number this isn't a huge turbo it's still pretty small in the grand scheme of thing s. And this type of dyno is really useful for steady state tuning not just overinflated WOT pulls like some dynojets.
4G63 motors were part of DSM R&D outsourcing that rumor has it...included head influenced design from Lamborghini. The reason was for a failed 'Trans-AM styled' homologation race series. Either way those motors sound like RIP SAWS under acceleration !!! Nice build~ AND...YES! Do the intake upgrade!!!!💪🤙🖖
Great build, Tom. I've been watching since the start. Why do you use manual boost control? You can run a 3 port solenoid with ECMLink. Turn the boost up as the rpm rises to compensate the drop of torque at high rpm, you will have a flat torque curve on the dyno and be more linear at the street at high rpm. Yea, and bigger injectors) Cheers
I like the Viper idea!!
New Intake coated with some black wrinkle paint for the super OEM stealth look!
New intake for sure!
What about looking into a Magnus intake manifold once you have bigger injectors? My buddy used a Magnus on his 1G AWD Talon that made between 500-550 WHP. Not quite sure on the exact power since it's been many years. If I remember correctly, it was a pretty tame rebuilt engine. I think the only big upgrade to the block was aftermarket pistons besides rod bolts and other essential bits. He was running E85 which definitely helped. I can't imagine how ridiculous this car would be on E85.
Actually the heart breakers are the Mustang dynos, who are the onese that started out with load based tests. Still nice to see load based numbers not made on the Dream-o-mometers, i.e the Dynojet dynos.
Forget what others say, this is the only way to compare numbers from manufactures. This is also the reason why people think Mercedes and Porsche claim too high numbers - they don't They just don't screw around with the numbers like most tuner shops do.
Do it, intake, do it. Haha. Great video.
Love the progress man!!
Fabulous work mr tharp👍
God i miss my old VR4 😢
Build the Viper Kart! Then get the RK guys to race you with their Vette kart!
Dang how did I miss this episode?
If you can find one, what about a HAFE intake manifold? Never used one but from what I had seen, they were a well executed cast manifold that showed gains most everywhere (best I recall) over the stock 1g manifold.
Bigger injectors...more boost!!! Do it, do it, doooooooooo it!!!
Tom i would really like to see you make a real cold air box , get rid of that ugly filter up the back of the bay. Nice looking alloy sealed box , up front with filter in it !
Woooo go Tom! What'd you end up doing to quiet down the exhaust drone you were talking about? Viper cart would be awesome, I say do it! Also, you've come this far, why wouldn't you slap a better intake manifold and possibly turbo manifold on the beast and go for more? Dooooo ittttttt
Tom's Back! :D
Awesome Tom!
Must people saying upgrade the intake don’t understand that the hardware is not the issue. If you fix your injector problem you’ll be fine. Boost is boost. Upgrade your fuel system to perform equal to the engines capabilities & turn up the boost. The intake is fine.
MrDruaboyea2U no. "Boost is boost" is very wrong. Less boost but more volume (CFM) will always make more power.
Build it!!!!! Is that even a question?
Such a clean car!
In the name of "what I would do!" I'd leave the galant alone now.
Also, aren't the body's on vipers crazy expensive? if you bought a salvage to sell those parts, that might greatly off set the cost making it a pretty great idea.
Nice HP score
Please more videos of the galant! I want to see some spirited driving!
Do it do it do it
Hello Tom!!!
love the power love the wheels good video tom
Magnus intake and speed density conversion just like the talon tom go on an do it
best video yet
Thanks, Tom, for another enjoyable video! Don't you wish you had your own private dyno to use any time you wanted? I hope you get your dreams fulfilled with your Viper car!
Thank you as always for watching Rick and for the very kind support! Oh man, a personal dyno would be so great! Noisy, but great! Haha.
You could always have a really well-tuned car by using a dyno. But, I don't need to tell YOU that, eh? I wish that I had the spacious garage, tools, and... a lift for my cars. That makes major jobs much easier. Thanks for the entertaining videos, Tom!
an e85 ecoboost mustang like a 80s body would be awsome build
Fucking hell! Small adjustments increased the power from 240 to 314 hp???? =o
