Thread: Anyone ITB'd a DE yet

Just checking in on an idea that was brewing several years ago. I am wondering if anyone was successful with putting the Pulsar GTiR Independent throttle bodies onto a DE. Seeing that there are some better ecu options besides the AEM these days, It seems it can be done. I am just wondering who has some luck.

I have heard its pointless due to their small size. I never had the experience with them and honestly I think it would be a waste of time. I noticed some guys even ditched the ITB's for a traditional big plenum/runners/single TB design.

^^^^truth

Didn't the the SCC 200sx have them way way back? like in the 90s?

The manifold will not bolt up to the DE head. It would have to be modified.

see that was the issue if i remember correctly but we were talking maybe a 14 inch difference. i remember back in the day there was talks of using the thermoblock spacer for port matching ( if you want to call it that). I was not coming into this thread thinking " oh shit mad power yo!". The only advantage i can see to them would be a little kick in throttle response for some autocross kicks. and the sound

I have seen on youtube where a guy put the GTi-R throttle bodies on a rwd SR20 however.

Charles used GTI-R ITB's on a lowport DE. Car made 200whp+ n/a, but had some good work into it. Jun 280*cams, custom header, valvetrain etc

He had a build thread somewhere on here.

But for the money spent... VE

come on someone has to be doing it old school. I'm not sure if I want to be bitten by the street modified bug in SCCA autocrossing. But how it is going it will eventually end up that. I can forsee a stripped out, caged, Carbon hatch NX that is slammed on 13x8's with a 240hp VE setup with an SR16 gearbox... shit. need to get a tissue now. This forum is such a bad influence.

Just quick search from what i remember with ITBs... GTiR 45mm ITBs will be just fine. Go for it!

I know someone who did it on a RWD DE. He called it the most pointless SR20DE mod ever, and kept an image of it, saying just that, for his signature for a long time on an engine tuning forum I'm a member of.
