What turbo

mmario_200sx17 Mar 2011, 16:01

Hey guys,

We are shopping around for a ball bearing turbo for the GTIR.

Seeing that this is a full track car, we are looking for something very responsive.

I was thingking the GT28RS turbo. What is the most power we can expect from a SR20DET motor with this turbo.

GT28RS is rated up to 360 hp

SR20det with 86,5mm piston

Ok awesome, and response?

How good is the response on those turbos?

GT3071 with 0.64 turbine housing.

Too big for track gary, its a 4wd so we want minimum lag.... I drove a RB with that size turbo and it wasnt instant enough.

Not looking for crazy power guys, just instant response.

We will be running 8" slicks in a 4wd car, so the resposnse can be instant. It wont break traction.

Sorry Gary I retract my staement there.... did some reading and you have a very good combo there! Should run suburb with some decent cams!

Yeah GT3071 is right, get some cams and RAS, retainers etc, so you can rev to 8 000rpm, then when you change you will always be above boost thresh-hold and the boost will be instant... 8)

I also say at least a GT3071/76, GT28 is good for a uno turbo, LOL

HKS GT3037/Garrett GT3076 is used by most at the tracks in japan!

You get many different GT28RS's...the GT2871RS is rated at 500HP

Best choice, or even a new GTX3071R, same spool, more power 😉
