I've searched a little, but haven't found much on the 4088R with a 2.0L. Most have been a 2.3 or destroked 4g64 to a 2.1L. So my question is, what could I expect to see as far as spool time goes on the 4088R with a standard 2.0L with a set of HKS 280 cams. My main goal would be to make very close to, if not over 500awhp on pump gas ALONE (no meth. or alky.) If anyone has any experience with this turbo on a 2.0L, I would appreciate input .

I dont think that would work out well with a stock 2.0L if thats what you mean.


On a stock 2.0L 500whp is going to be very hard to come by without meth or whatever.

on a stcok 2.0.... without meth/ or race... it is damn near impossible.

Stock motor or stock displacement? Doesn't really state..

As for spool.. I haven't had one on an Evo...but one of the Honda's here at the shop was running a 2.4L K series setup with a BB t3/t67 P trim (aka gt37r). We switched to a 2.0L with a twin scroll manifold and gt4094r. Guess what spooled faster and was more responsive and made 800+ whp

This would be stock displacement, def. not a stock bottom end .

^Then its definitely possible. Look at David Buschur pushing 30psi on pump gas.

If you haven't bought 40R then my choice would be 35R. It is hard but not impossible to achieve 500awhp mark on 93octane.
Search a little here & you'll know what I am saying
Good luck!

A guy in my Country has recently got his car tuned on FR twinscroll 40R setup on built 2.0L. Through some sources I have come to know that he is facing more lag than a 35r but may be it's the combo that is not letting more power out or may be unless one races him, it cannot be declared. If I get some authentic info on that car, I'll surely let you know.

My speculative opinion: 5,000 RPM and I hope you're completely built. You'll have to rev that thing to 9k+. Of course you don't have to, but then you'd be limited to a 2,500 RPM power band. Everytime you shift you'll fall into lag range. You'll lose races against stock Evo's at that point.

My 2 cents.

heres a k series with GT37R single scroll .63 A/R VS GT4094R twinscroll 1.19 a/r



being that you are in europe, i assume you visit lancerregister? one of the most respected forum members on there is Mark Shead... i highly recommend asking him his impression going from GT35R to twinscroll GT35R to twinscroll GT40R.

the twinscroll 40R has less lag than the standard GT35R (singlescroll) and a fantastic powerband

sorry, but that is completely false

That is surprising. I wouldn't expect a 4094R, and with a large 1.19 A/R TS T4 housing, to outspool much of anything.

ye i am also shocked ...
4094 is huge and has 42r internals just with smaller housing.
I will have some feddback for you soon but i am running full race 40r kit with buschur stage 3 long block.

I stand corrected--somewhat. He asked about a 4088 singlescroll on a 2.0 with HKS 280 cams. Your example is great, but that's on a honda motor and a very different turbo. It still stands to say that he MUST have his head built or he'll have to stop revving at 7500. So his usable power band will be LESS than what I stated. He'll have about 2,000 RPM's to use. My statement about losing against stock Evo's was an exaggeration, by the way.

Not sure if you saw my thread but here's some info anyway.

FWIW we just dynoed a car that had a lot of 40R setups on it, and tested out the new borgwarner turbo thats between the 40R and the 42R, and it kicked ***

spooled a tiny bit faster than the 4088R, and made more power at less boost with a broader powerband. BW is coming up!!! ill post the dynoplot on monday
