Turbo for Audi A4 (B5 chassis) Quattro with a VR6 3.2L 24v engine

Question

Hello, I'm looking for a turbo for my project.

I saw that you have a lot of knowledge in the field, that's why I'm heading towards you.

It's one Audi A4 (B5 chassis) Quattro. I have a VR6 3.2L 24v engine (Golf
Mk5 R32). I started the conversion to turbo.

My engine configuration 84mm x 95.9mm and now my RV is approximately 8.4:1.

I would have a final power between 700 and 800whp (if it's possible), 24psi max turbo pressure. My rev limit will be 7500rpm for this engine.

It's a car for street racing and dragrace 1/8 and 1/4 miles.

I want to have a quick spool and good stability in power.

It's true that I ask a lot of things, but I want to know what you can advise me as a model of turbo.
Thank you for your reply.

Answer 1

If it was me, I'd either do a Garrett GT4088 or a GT4094R. Good spool from your VR6, and good top end capacity. Power figures are not only controlled by the turbo, but manifold design, engine management, etc. Id do either of those two turbos though personally...
