if i have the setup as follows: disco potato t28, z32 MAF, fmic, 255 walbro, 3" full exhaust w/ test pipe. MR manifold and outlet

will 440cc injectors be big enough to reach 300-320 whp with a tune of course? or will i need to go to 550cc or 555cc injectors?

go with 550, 440 would be pushing the limit of the injector

S15 injectors are 480cc and should fuel that fire. But I would leave some extra head room and shoot for 550cc's. It least that's what I plan on doing. The 440cc's are top feed right?

My names billy and I'm in your area. Do you do any motorsports in this area? TR?

I have the same SN on TR too. I have been drifting at desoto super speedway for a couple years but I found that autocrossing is still fun but cost alot less. I have been to the last 5 FAST events. They are on TR, Here's a web sight :http://wedrivefast.com/ They get to use the police training course @SPC on 34st acrost from walmart on the southside. I still go drifting but I want to expand into grip as well. Is there a autocross group your interested in?

to be honest i have not really looked into it that much down here. im still getting the car prepared with better brakes, getting the engine in perfect working order. im hoping by mid-summer i'll be ready to get to an event, which should be interesting
