ok so now for the parts list. just trying to make sure i haven't forgotten any thing.

Now since you're ordering lot of stuff from ebay, cross your fingers you get the right stuff. Next, you're missing oil and coolant delivery to the turbo and the fittings necessary for that.

most of it is not going to come from ebay i was just using it as a reference since it was easy enough to find all the bits and pieces. and good catch on the oil and water lines...

so next question where does one find an style fittings for the t25/t28 turbos? my google fu is failing

i;m sure jegs has them but i'll be damned if i know what thread pattern the t25/t28 turbos have.

so what bov would you recomend?

on the ebc. i was under the impression that a bost controller would be needed to up the waste gate pressures to the roughly 12-14 psi i would need to make the 200 whp i'm shooting for, since most of the turbos i've seen we pushing 6-8 psi wate gates. the ebc from megasquirt seemed like a fairly good cost effective option since i'll be using ms anyway.

what do you mean you don't need gaskets? and where do i find the appropriate flange with v bands?

i know the manifold is not great, and prone to cracking, but this it the best of the tube type that i saw for cheep since it's using the extra gussets and bracing. i'm hoping once i add a support bracket to the manifold to help support the turbo weight and do the same for the down pipe it should hold. if not i'm only out a couple of hundred bucks. (in the end you get what you pay for though. i'm well aware of that)

oh and injectors!

after beating my brain against the wall for 20 - 30 minutes i realized that i need a 454cc injector since i'm going to run the stock 43.5 psi fuel pressure... which is the closest match to Braineack's reccomended 460cc RX-7 injector /facepalm.... of course i see that after i worked though all the math problems below it in the faq...
