Hey, I have read tons of threads and info on the 5sfte project, and I am getting a bit of mixed info. I was wondering if you guys could help me get it straight. Some places say run 315cc injectors, and some say 440cc...not sure if both will work fine, or which ones I should go with??? Also I have seen in a couple places ppl say to upgrade fuel pump to walbro 255hp, but most threads don't say anythin about changing fuel pump.. is this needed at all, or can I do without?? Planning on ct26 with 3sgte manifold, running around 7-10 psi. Will be dyno tuned also.

You'll need the walboro 255lph fuel pump.
As for injectors, I'd say the 440cc's. If you're looking for 250hp, 440's will run at about a 90% duty cycle depending on what your fuel pressure is, which you also might need a fuel pressure regulator.
What do you plan to use for engine management or piggy back?

my setup ran the RX7 440s and i used the stock fuel pump no problem. I was using an FIC and stock map sensor.
the information you read about using the 315's and the 3S-GTE map sensor worked on MR2's they had an older version of the 5S and older computers. that setup doesnt work well on the 6th gens
