what turbo?

I've been thinking.

i have a s4 fc rx7 running a s5 motor and box.. the engine isn't in yet because i am taking it in too get a rebuilt in the next couple of weeks, i have planned too go ahead with a 13b motor being slotted too 3mm with the secondies ported. then using something like a t66 turbo with a mirco tech lt10 running around 18psi..

Is a 't66' turbo the way too go? or should i think of something alse? i'm not too cluded up on turbos but would like too find out what people think and maybe learn something.

The T66 is a big turbo. You'll need to do some pretty serious fuel upgrades to run it. I'm going to be running an A-Spec GT35R kit this season and I'm running an LT8, two fuel pumps located within an in-cell collector (surge) tank. I'm current running 550 and 1680 injectors, one pump for each rail. I'll likely upgrade the primary rail to 720's before I get serious about the boost though.
I think your biggest challenge might be heat though. I run a huge circle track car rad along with a great deal of ducting up fornt to keep the temps down. I think you'll have to go a similar route.
18 Psi is also quite high for longevity. I'm planning on 14
