I wouldn't say hype. The results were probably poor.

No, it is not a hype thread. We spent a lot of time on this setup dialing it in for a completely stock vehicle. What we found was the power/torque gains are all in the middle of the power band and the top end is the same. No do realize this is on a 100% stock car otherwise, running 91 octane.

The next step is to get some headers on the vehicle and see what it can do. Also working with an engine builder on some suggestions he has to make the ITB's really do their magic.

Were the gains noticeable and repeatable, or anecdotal?

Nothing wrong with more midrange.

One would argue that additional mid-range power on this engine would be welcomed. Were gains substantial?

truth is, the only reason i want to do ITB is for the sound.

as long as it has that, i'll be happy.

Damn. 9 pages and nothing. Feels bad

In another thread somewhere, I think someone mentioned they were putting a new engine in the car, so it sounds like testing is still happening. I'll try and find where I read that.

Heyo, I found it. The Ultimate FA20 ITB thread

i still have hope

I woudn't be so hopeful given what's been flying around FB lately...

Looks like greddy is stuck with some itb kits for awhile

Unless you saw something different, I don't think they're any more stuck than they were before. My comment was about the stuff between Delicious and CSG.

Yeah but everyone is waiting for zach's or dts tuning results before deciding on them.

There is a dude on Instagram with the Greddy ITBs and a turbo kit and I'm pretty sure I saw an article in Super Street about another one with them. If we're all waiting here for one tuner to show results, then where the hell did those guys get their cars tuned???

Any real reputable tuner worth his title should be able to tune ITB's.
Just prepare for a ton of $$$.

Sasha at Onpoint comes to mind here in Toronto, he has the knowledge and experience to get ITB's running on any car provided it's not a hacked together job.

CSG announced a partnership with Zach too...

People are hoping this will be the next big thing for na results. Nobody has been able to provide conclusive before/after na dyno numbers

Agreed. There have been a couple of completed ITB conversions, both in Canada oddly.lol One guy was satisfied as it was a shop T/A car runninga Motec and the other one said for the cost and complexity it isn't worth it.



Personally I'm more than happy with my extrude honed MY17 intake, but hopefully the RacerX IM performs decent on E85 since it would have been cheaper all said and done.

I don't see it adding significant power without some much more drastic done to make the engine breath better above 7k rpm. Cams, headwork, etc.


Will it have better response, absolutely. Will it suddenly let us make 250whp on internally stock engines, no chance.

And once we go above 7000, more than just an oil cooler is needed to ensure adequate lubrication on this mill.

I'm keeping a hopeful eye on these kits, but they are expensive and their biggest issue is no trumpets. It seems almost pointless if they don't have the trumpets haha

Revs to 8500rpm


1st pull: 210whp
2nd pull: engine seizes

Why do you say that? Stock redline is 7400. I've been driving mine hard for more than five years and 100 track days. It seems to me like regular oil changes with good oil gets the job done as designed.

Zach is a partner, as in equity partner, at CSG, not just "a partnership like a sponsorship"!

The original CSG vehicle supplied to DT with my ITBs for NA development suffered an engine failure while on DT's dyno.

The ITBs have since been transplanted into another CSG vehicle for NA testing, before I take them back to put on my personal turbo car.

Testing is ongoing, not only for power, but also drivability.

Mike, just so you know, I'm just a bystander here lol and would never question your experience or the time and money you guys have put into developing parts for this platform

They haven't realized there are tons of people that have changed their cars redline to 8k. I think I read on here that people have used 8200 or 8300 safely as a redline. Above that is where it gets iffy.

Sustained 7000+ rpm has been the demise of more than a few of these do to oil starvation, on engines that have never been opened, so we can't blame sloppy sealant application.
I thought it was pretty common knowledge that that oil supply system really isn't up to snuff on this car.

Why in the world would anyone sustain more than 7,000 RPM on these? There is zero benefit to doing that. That is strictly abusive.

Did anyone tell this to that guy from the main forum fighting the dealership about his blown engine?

Lots of AutoX cars will be bouncing off redline consistently at the top of 2nd gear.

Bouncing off the red line consistently does not sound very fast to me.

There's a high likelihood it yields better times than upshifting and then downshifting again immediately.

ACS Roval usually ends up with redline in 5th for about 20-30 seconds WOT. If you're mostly bolt-ons there's barely enough power to keep the car going at that speed on the bank.

In 6th there's not enough power to the wheels.

Not really abusive if you want to get faster at the track, but you're right, it's abusive in the eyes of SOA.

My crappy driving:

Same story here. I've done about 40 track days on mine. Nothing crazy with my setup, just an oil cooler and Castrol or Mobil1 synthetic 0w30 or 5w30. Plenty of trips to 7400 RPM, although granted I don't sit at redline and bounce off the limiter.

Engine is running great. Now that I said that though, it'll probably explode tomorrow. :D

"i HaVeN't HaD aNy PrObLeMs YeT!"
The fact of the matter is, we know this engine has oiling issues, be it starvation, lack of pressure, over temperature, or all of the above. You guys do whatever the fuck you want with your own cars, but don't try to pretend like you're bullet proof reliable at redline, because that just isn't the case. An oil cooler is a bandaid for the actual deficiency.

You sound like fun at parties.

People at parties not like the truth or something?

While I neither condone nor encourage it, I occasionally rev up to 7800.

Anything over the factory redline of 7400, is "at your own risk", and you 100% will not be under warranty of any sort.

It isn't ideal, but...

In a 60 second run, you might have 5 or 6 instances where you get 2, 3, 4, 5, 6 or maybe more limiter hits. Sometimes you would have to immediately downshift, sometimes there isn't really a chance to take your hand off the wheel to upshift and/or downshift.

The only engines that have consistently blown are the ones with ridiculous redlines, like 9k. There is zero proof the stock redline will blow up cars.

Oiling issues aren't about the rev limit. Many cars would have oiling issues if you tracked them, because most cars you buy off of lots are not meant for that.

People that actually take care of their cars will be fine. You use your car in a way that the manufacturer did not expect, and you will have issues you need to correct. Every issue is correctable.

Stop pretending these are made to order race cars.
