the throttle bodies are suzuki gsxr 750cc throttle bodies. I chose them because they are easily separated and spaced for the 1.8bp.
mx3forever of clubprotege was the inspiration but he eventually gave up on his and sold them.
For the whp I am planning i dont know what to say. I am hoping for at least 240+whp with the T25 on the test engine since it has 9:1 compression. Some miata guys have put down ~220whp running 12psi on the same saab .48 T25, but they have a higher drivetrain loss from the RWD trans, no tubular manifold, no ITBs and no 94 octane gas. I also hope to be boosting at 16psi instead of the 12psi they ran as I am in freezing cold canada and not in hot texas. So who knows what will happen but it should be interesting to say the least.
The GTR bottom / MK2 top I dont know what to think. The realdieal is putting down well over 300WHP with his GTR motor with stock gtr head, which flows worse than the n/a bp head, and nowhere near the mk2 head.
So if I size the turbo large enough over 300whp but until I am ready with a LSD in the toyota trans I dont want to swap the GTR in. As there is lots of snow on the ground here I dont think GTR will happen this year, probably get swapped during april 2011 when i take a week off for my birthday.
Pretty sure therieldeal (guy who makes the toyota trans adaptor plate) is running11.87 @ 117.6 mph in his GTR escort right now, but he is a bit lighter than my MSP so i am not sure how I will do at the track for 2011.
pretty sure his is still running the GTR vj-23 and stock gtr head. So with a larger turbo, larger injectors and a better head (mk2 vvt) I would hope I could at least get in the 12s with my heavy MSP.
