- First drive out on the ITB swap. Still needs a proper dyno tune. ITB kit by @xcessivemanufacturing7701. Tuning on Link G4+ by Xcessive Manufacturing. Engine harness by Guy Nelson at Xcessive Manufacturing. Running factory 2JZ VVTI through an FRS/BRZ TL70 6 speed transmission.
Bro, you are literally a pioneer in the IS300 world. I've seen maybe 3 IS300s with ITBs, and that's only in the last 2 years because before that there were NONE. AND yours is the first video of one I can find. PLEASE show us more along the way, I wanna know EVERYTHING.
Appreciate the kind words man, I'll have more updates as soon as I get some bugs sorted. I'm no pioneer though, all of the engineering credit goes to xcessive manufacturing. I'm just fortunate enough to test new products and be involved
@@madchyers5416 How much $ was it for the whole kit ? If you don’t mind me askinh
@rybhugo I can't honestly say what the total price comes out to, it's been a long process of putting parts together/making parts. I would ballpark near what it would cost to put together a decent quality turbo kit. So if big power gains are what you're after, ITBs definitely aren't what I would recommend. But it does make changing the oil and doing your spark plugs a lot quicker 🤣
@@madchyers5416 will these eventually be on the market? the adapter flange and possibly kits?
pioneer? but of what or in what? I'm sure you're 18 or something, the sxe10 platform is being modified at high levels since before this guy was licensed 😂
Love the responsiveness of a N/A motor
It's like a 2 stroke. Instant & controllable but raw power 🔥
Incredible man, love that sound.
In the market for an IS300 soon. Keeping a close eye on this as I'd like to stay NA. I added excessive manufacturing's website to the favorites and subscribed to your channel. I'll check their website from time to time for any updates. I hope you'll consider doing a few WOT video's once everything is sorted and mount the camera/mic near the ITB's as well. So awesome. Thanks for sharing this.
This is nuts!! Thank you for innovating, man! Absolutely sick!
Sick ass hell, you dont see many n/a 2jz builds. I imagine the iat being high on a set up like this though, these motors like to run HOT ass hell.
Not really, 2jz's actually run quite cool compared to today's standards.
@@motabikeboyman my is300 2j runs alllottt hotter then my nans 2024 kona i mean am comparing a 4cyl but still a lot hotter
my mad chyers is back!!!!! those back fires are insane
They sound like gunshots lol, definitely needs a bit of a tweak in the tune on de-accelleration. Probably will be fixed this weekend
Sounds great, fitment is also extra mccrispy
this is art i hope ur keeping it N/A forever lol
sounds fucking great
We need an update on this build ! sounds amazing man cant wait to see it tuned.
😮fr we need more content
insane
Waiting on an update, your setup is something id like to do too
Sounds really good. What header are you running?
Fuck sounds dope
Do you have any updates? Love walk through of the transmission and what it took to make everything fit. Of course the ITB system as well with filters and all the info about that. :-)
Nice job.
WHAT were the power gains , i want to do itbs on my is300 after hearing the sound. it would be a fun project for the summer
i'd take this over an e46 m3 tbh, respect
What shifter are you using? Interested in doing this swap with my is300 as well
I've been looking to ITB my personal IS and I have a list of parts down but I'm sure I'm missing something: So I've got the ITB kit i want to run itself, 2.5 inch diameter fig headers, custom catless midpipe since I couldn't find a branded one I liked, I already have a Tanabe Medallion Touring S catback on it, I'm looking at fueling mods like bosch 440cc injectors, a flex fuel kit (just bc e85 is readily available around me and I wanted to give it a shot), a SPEC stage 2 street clutch, Brian Crower spec 264 stage 2 cams, I've budgeted for whatever ECU a prospective tuner would feel most comfortable running, budgeted for a clutch safety bypass to prevent crankwalking (probably unnecessary since the clutch isn't so so aggressive and the car shouldn't be pushing a ton of power, but better safe than sorry imo), and I have a catch can in mind for the chance that I end up getting a lot of blow-by. Is there anything I'm missing still? Thx.
Everything you listed seems fine. The biggest factor, besides the actual ITB kit, will be ecu/tuning.
Sounds fire until a rock gets in
I doubt that happens often and I’m sure you could put some sort of mesh cover over them
We made filters for each stack
Any power difference?
Subscribed! Should do a dyno on it and as many other videos on this as possible lol I have an IS I wanna run ITBs on but there’s not much information for ITBs on a jz
Also looks like there’d be some weight savings just by going with ITBs would be interesting to know how much weight you saved
@kevincorrea3563 I think the weight saving is negligible, the stock intake manifold is aluminum and the airbox is plastic
@@madchyers5416 the stock TB kinda heavy too though. Any chance we’ll see a dyno run?
@kevincorrea3563 honestly the throttles that replaced the single throttle body might outweigh the stock throttle body. Dyno video hopefully coming soon. I haven't had much time to touch this thing in months.
can u put in 3sge altezza these kit
Ive been planning on this for sometime, there arent many companies that make itbs for this motor so ive been struggling with that as well as deciding on which stand alone to run with the setup. Id really like to pick your brain about what youve done with yours if you dont mind. The car looks and sounds great.
You'll need a standalone, and a good tuner, that can use alpha N tuning (throttle position) instead of most traditional tuning strategies using speed density (MAP). I have Link G4+ in this car. There was a lot of work that went into the kit and making everything fit right, as well as sacrificing some creature comforts like AC. I have a friend who was able to keep AC but he had to have custom lines and fittings made to fit without interfering with the throttles.
Are you using an O2 SIM for the header or is the standalone taking care of the codes that come up from it. Did you leave the motor stock as well? Or did you upgrade any internals?
I see what you meant about the a/c it looks like you left the condenser attached but not hooked up that way you weren't dealing with finding a belt that would work with the different length.
@kaylabeitz1464 there aren't any check engine lights, the Link ECU replaces the factory computer. The Link will throw check engine lights if there are any faults. No o2 Sim required, no o2 sensors required, I am running a wideband gauge as well as having it wired to the Link so it can monitor AFR. I don't have the condenser or the AC motor in the car, im running Xcessives PS brace/AC delete kit with a shorter belt. This motor is an unopened stock vvti 2jz.
I'd like to do this to my gs300 someday. To run itb's though, do you have to run an aftermarket ECU? I know there are some guys in Russia, Tuning/Re-mapping ECU's for 01+ Toyota/Lexus'. The only build info i've really seen online for an n/a 2j is Brendan Taft's build (NA HERO). Great looking and great sounding car you have there 🤙
Thanks man, yeah you will 100% need to run a standalone computer. The stock ecu will not be able to control ITBs, even with a re-map. There is no MAF sensor with an ITB setup, so the mapping is controlled thru throttle position/rpm (alpha N).
Any update?
NA all day every day

Can you make a video on the TL70 swap in an IS300?
Yeah I'll go over the process next time I'm at the shop.
This video hits. How do you like the TL70 6-spd? Are you using the BRZ's LSD or stock LSD?
It feels great, currently stock IS300 LSD rear end but I'd like to eventually swap to FRS/BRZ rear end to make it a perfectly matched gear ratio combo.
Interested to hear you thoughts on the differences between the W55 and TL70 trans? Worth the swap if staying NA? Thanks
Pros: they are a dime a dozen to find at junkyards, I used car-part.com to find mine locally. They're going for $250-$350, which is a fraction of what you'll find for a w5x. The gearing pairs well with the IS300 rear ends, and if you swap the FRS rear end, then it makes for a perfect combination. They can take the same amount of torque that a w5x will handle, which makes it a great candidate for an NA setup. The 6th gear should improve MPGs as well. The shifter feels really smooth, though I will admit a w5x with the stock IS300 shifter is hard to beat as far as how smooth the throw is.
Cons: it is not a native transmission to the IS300, so there are some things that have to be done to make it all work. There are 2 ears cast on the sides of the bellhousing where the FRS/BRZ starters would mount. They interfere with the trans tunnel, so some clearancing was required. The factory external slave/shift fork are located at the top of the bellhousing, which will not work either. So Xcessive Mfg designed an adapter kit to convert to a hydraulic slave cylinder.
I will continue in the next post.
The cool part about this swap is how Xcessive has a clutch kit option to adapt to the single mass 2J flywheel or an FRS clutch/flywheel/pressure plate. So there are options depending on where you're starting from, whether you're converting from w5x to TL70 or swapping from auto to manual.
I would recommend this swap if you're planning to go auto to manual because there are expenses that will be made regardless of which route you take. Those being: clutch/flywheel/pressure plate, driveline, clutch pedal kit, hydraulic lines and fittings, master cylinder, shifter. All of these can be conveniently sourced through Xcessive if you were to opt for this swap, or a w5x swap for that matter as well. So really all you have to source on your own is the transmission, which brings me back to why I would recommend a TL70. They are a lot easier to come by, and they cost about 1/3 of the price of a w5x. You're getting a 6 speed transmission, newer tech, and less mileage effectively cheaper than a w5x swap unless you come across a killer deal on a manual IS part out locally.
@@madchyers5416 This is excellent information. Thank you so much for the detailed explanation. I'll be saving a screen shot of this for future reference. Looking forward to your future videos with the ITB setup as well. 🤘
Did you have to get a standalone to run the itbs?
Honestly I’d love to know aswell if your speaking ECU , not fuel system
Yes I'm running a pnp Link G4+ ECU with a custom made wire harness, there's no other way you'll get the ITBs to run right without proper standalone engine management.
do you have videos or photos off the proses okk making it? or instalin it
I dont have videos of the installation process, there is a lot of work into it.
What rods and piston set up you running?
The bottom end is unopened. I had the same setup on a high compression build and it made the same power as the stock bottom end. I think the cams are the limiting factor, and would make the most difference. High compression with more lift/duration would probably really wake this motor up. I'm planning to install BC 264/264 on this current set up and see what happens.
What’s that’s transmission whine? Mine sounds just like that lmao
I havent put the covers back on the center console so it sounds like a race car haha
Does it work with the vvti
Of course, all controlled by Link ECU
lordy lord
do the itb's need an aftermarket ecu?
Yes
No redline pulls??
Still needs a tune!
@@madchyers5416 Oh ok! You drove sensibly then :)
Info on trans swap pls? thasts solid
It will soon be available thru xcessive manufacturing, everything you need minus the transmission which you would have to source yourself.
@@madchyers5416 how has the trans been holding up?
Where can I find a page about the TL70 trans swap??? I need to get rid of this awful w....
The full swap kit will be available thru Xcessive Manufacturing, ill eventually post a better documentation for the swap in another video.
what’s the front bumper?
Elixir
timing belt sounds like it is to tight that’s what the chirping might be
What kit is used to get the TL70 in there?
Xcessive Manufacturing made the kit. It is a pre-production kit at the moment, but will be for sale on their website soon.
@@madchyers5416 sweet. How much was the tl70?
@@KnownworldwideSup Uce you also checking this out too? Pretty dope huh?
@@BongoisaPyro what’s good family! Yeah just looking for other options for manual transmissions instead of the hugely overpriced OLD transmissions.
@@Knownworldwide yeah forsure those itb sound sick on the 2jz
So like a bmw but better
