I'm building a 93 mr2 in an attempt to break the factory chassis mr2 e.t. record of 9.66.
The motor is a 87.5mm bore x 92mm stroke 2.2 with a decent 3rd gen 3sgte head (similar to a b series in port design). going with gsc 268 cams.
Anyway, I had my heart set on the EFR 8374 .92 twin scroll internal gate, but they're apparently unavailable. So do you guys have any preference as to what the next bext thing is. I preffer a twin scroll setup. I was looking at the 62mm precisions and the Comp ct3's and ct4's. I'm having a hard time deciding on the hot side. I basically want the twin scroll flow equivalent of a .63-.82 a/r t3. I'm not sure how that works out in the t4 sizes. I can get a t3 1.15 divided in the Comps though.
Help me out.
I need to make 600whp and have 400whp by 4500rpm with a 8000-8500 rpm rev limit.
