Having no luck selling my AFI stuff I will just keep it. Now I need to decide on a turbo for my setup.

The manifold is a twin-scroll with a T4 turbo flange.

I've narrowed it down to a gt3076. Now im just wondering if there is a series with the Precision brand turbo.

For the gt3076:
T4 1.06 a/r t/s housing

Precision turbo: ????

Please provide some suggestions here. Thanks!

BTW: I like quick spooling turbos

why go with such a small turbo for a twinscroll setup.. id step it up to a 35r divided housing with the 1.06 a/r

^ Because it seems like he wants the quickest spooling turbo within his power goals. If his power goals fall within the range of the GT3076 divided why go larger?

Power goals?

Please define "quick spooling".

If I had the AFI stuff I would definitely go with a GT35R.

a gt35r twin scroll is gonna spin so fast. its not like anyone drives this car under 3k rpms anyway

I think a twin scroll gt3076r would be absolutely nasty...isn't that what AFI runs on their own race car?

towards the bottom a dyno of a AFI mani with a gt3076 on E85 @ 16psi:

if u drove the car at like 3500rpms. it'd spool up instantly. and faster the higher your up there hahaa. besides... when you race, your usually at like 6rpm anyway

lol I wish I saw this thread a while back.

I asked about a twin scroll manifold setup for GT30R back in 09, and people just laugh at that idea.

What's changed since 2009 that makes people think that this setup does work??
