SR in natural aspirated mode? Hmmm...

[chickentendah]

This curious question popped in my head one day:what would happen if you removed all the turbo parts on a SR20DET and tried to run it as NA?

If you were broke as hell, and you didn't want to fix leaking pipes and a blown turbo, could you still drive your car?

Hmmmmmmmmmmmm

MAYBE if you changed out the injectors and the ecu...otherwise I just don't see it running very well.

[ride4lame]

i think you would need a different ecuadn the compression would be low as hell so probly not well. I think it would cost more to run it non-turbo then fixing whats really wrong.

[Onizuka]

It would be more expensive and less powerful than just buying a RWD SR20DE.

[Cyberkreig]

I'd be willing to bet it would run just fine. What are mass air sensors for ?

[VitaminT]

I thing it would run okay as well. Probably slow as crap due to the low compression, but I think it would work. I know my SR will idle without the hotpipe on, but have never tried to drive it without the turbo.

[Onizuka]

So in other words, yes it would work, but it would probably only make like less than 90hp at the wheels.

[Cyberkreig]

yeah, definatly not the prefered way to do it.. but possible in theory (or thats my opinion anyway)

[240Kuminachu]

I did it with mine for a few days. It was gutless as hell. I had my SDS tuned for the turbo, but without it, it ran fine.

[Hijacker]

i've ran my engine without a turbo and it sucks. I had an issue where the e clip that holds the WG actuator arm to the WG door fell off, so the arm would randomly fall off. The car has absolutely no pick up and go then.

[usdm_180sx]

Your car would then be a Q's model

Toda racing has a SR20DET with a nismo N2 head that's using ITB's instead of a turbo. Might want to go check out todaracing.com under the race engine page.
