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?
