what do you guys think of 550 prim and 1600 sec on the stock turbos and motor. i plan on going with the apex bb rx6, is the 550/1600 to much? what are you running with what single turbo?



mods so far:

act strip/street clutch
hks dp
pettit resonated mp
apex gt sec exhaust
apex gt intercooler w/ intakes
apex pfc
apex turbo timer
autometer boost and a/f gauge
new vac lines

i plan on getting a fuel pump, most likely the bosch fuel pump and a fuel regulator.

1300s should be enough for your setup. You can buy them now and keep the stock rail then if you end up running out of injector you can upgrade to the 1600s with the new rail.

1300s would be good for at least 450rwhp.

450rwhp is all i want. what else do i need for fuel?

I use a Greddy T-78 w/ 550 prim inj. and 1600 sec inj. I dont think you should have a problem with it since your going single!! And the car is still very drivable. kinda of drives like stock twins

Someone that has gone the 1300cc route might be able to give you specifics of what you need. From what I know, all you need is the injectors and install them in the stock rail.

Plus of course a better fuel pump.

thanx for the replies, i was told by jason that 550 prim and 1300 sec would be fine, if i need more to go with 850 prim.

Still fine tuning car but generally having no probs with 1300cc secondaries. Car pulls pretty hard from 3500 on up.

Just buy some Blank rails $15 a foot and have a machine shop drill the hole and tap the ends thats so easy on a 2 gen.

If you take Bosch 1600's and cut the plastic around the top they will slide right into your fuel rail. You can also take an 87-88 TII fuel rail and bore out the holes until the 1600's fit. Both methods work well.
