what size should i do... injectors
ok I want 300 SAFE hp heres the parts/setup i have underway. 87 t2 motor, new housings, LARGE street port. 2mm 2 peice seals, 1 peice corner seals, all new internals and high vol oil pump and reg. i might do a light flywheel later. 4 puck clutch. BNR stage 2 to4 (90 turbo) r.b. 2.5" d.p to a custom 2.5" or 3" exh. I have a staron fmic and i figure 2.5" piping on that. ill have a microtech LT8 running this. I want a good safe setup in the 300 on the ground area. i have looked at a few setups like 550 prims with 720 sec. but i think thats gonna be on the line of not being enuff. then i thought 550 and 1k's but i think thats a LARGE jump. then i thought 680(or 720) primes(-se) and 1000 or 1200 sec.
I want to beable to pass smog if i need to(4 more years ). i just want a good safe motor that i can get lots o miles from... i mean im gettting new housings just cus i think these are MARGANAL and i want this motor RIGHT so i dont want to mess up by running to high duty cycle with to small infectors.

I don't think I would recommend 720cc for PRIMARY"S you will run RICH at idle. Maybe 680cc gsl-se injectors in PRIMARY'S. as far as SECONDARIES either 720cc or 1000cc will be suitable. Also think about up grading your fuel rails. I know SR sells some nice ones. Fuel pump is inevidable.

I'm running 4x720's and idling fine just using a Field SFC-HyperR to control things.

BUT IT DID LOOK GOOD

I have several "big" fuel pump upgrade here:  http://fc3s-pro.com/TECH/MODS/FUEL/fpump.htm
I have extreme fuel system FPR diagrams here:  http://fc3s-pro.com/TECH/MODS/FUEL/fpr.htm
The stock fuel rails can easily support up to 500, so it's not a choke point.  Running -6AN under the car from the fuel pump to the front is really overkill for your power requirements, but going with -4AN is too damn small.  -5AN is pretty hard to find.
