I'm just starting my new build, its going to be either 9.7:1 or 9.4:1(i haven't yet made up my mind on what rotors i'm going to use), inside a 13b-re block. As far as porting goes that were my questions come from. rather than by a template i've decided to make my own and was wondering what you guys think of this exhaust port so far. this is just a rough cut on and old housing to get a decent port on so that i can make my own template.

the rest of the setup is 13b-re irons(which are also going to be a big street port), a t4 p-trim t67 with a e-cover rather than a s-cover on the comp side, 1000cc injectors, full -6 fuel lines, bosch ext pump and surge tank setup, hks log manifold, hks 44mm wg, hks gd pro twin plate, 3" dp and apexi gt spec exhaust, and it has a microtech lt10s.

the car is mostly going to be used for auto-x and spirited driving, so as far as power levels go, its not a real big thing. it made 350whp with a stock re motor, so it should be intersting to see what it makes now at 14psi.

so here's the first attempt at the exh ports.

 

Hey man, interesting to see another high comp build. I'm doing mine with 9.7 rotors and am looking for around the same results as you. Auto X/Daily/Spirited driver and am looking for 350ish as well when I have my setup complete.

Any thoughts as to whether you'll be going with 9.4 or 9.7?
