MR-2 3SGTE turbo choice
My housemate has a Rev2 MR2 turbo and after lurking around here at my reccomendation he has decided that he can no longer live with miatas making more power than him!
So he has asked me to give him a hand with building his engine and upgrading the turbo with a power goal of 320-350bhp in mind.
So far we have assembled a shopping list of bits and materials required for the upgrade. This includes: Rods, MS, COPS, new manifold, new down pipe, etc.
What I'm not sure of is which turbo to use. Being a 2 litre I initially thought of using the GT2871 (maybe even go baller v-band like Sav). But my thoughts keep drifting back to the 2860rs which I think would have killer response on this setup.
Can some one offer some opinions on this?
He also has his heart set on an external wastegate. I know that this is available for the 2871 but after searching for I bit I turned up nothing on the 2860. Is there an EWG solution for the trusty tater?
Thanks
Tom

If you wait a little while you can compare pre-pubescent Savington's 2871 data to my gt2860rs d1zc0 p0+@+0 on the same motor, manifold, and exhaust. Look at the ATP site/catalog, you can get the housing with our without the wastegate and they're the same for both turboz.

There are a few people making 300whp on a GT2860, but they are having to try real hard to make it there. Most people I see running in the range your roommate is looking for are running a GT3071 or a TD06.

The weak link on US motors is the intake manifold. It doesn't distribute the charge evenly, and #3 (I think it's that one, it's been awhile) runs lean. It cooks even if you pull timing to prevent knock. Everyone seems to have trouble at about the 340 whp range with the stock intake mani.
If I was going to do one, I'd make a good exhaust manifold, use a Disco Potato, and a new intake manifold.
