1000cc primary injectors is a bit overkill. What size turbo? What management? What goals? Just looking for some more detail on your build so others can give better advise.

im lookin for 400hp or just over. im gonna put in a high flow 255 walbro, or at least i was told to. should i just put 1600cc secondary? what differrence will it make if i change the primary. i have a microtech in it. can i just program it to give less fuel from the primarys?

I think you should go with a bosch pump, I hear walbro's do have problems but are good for lower numbers. 400 is a bit much to be aiming for at first IMO, from what everyone's told me so far and what I've read, it's gonna take a lot more than it would to make 300-350.

What motor is this S4 S5 RE REW ect? Daily driver? Don't even need that much. I forgot exactly how much power the walbro 255 is good for. There is a fuel/hp calculator somewhere that is fairly accurate. Im thinking 850cc/1000-1200cc is what would be good for you but dont quote me on this. And i believe you can tune your injectors with your microtech. Best to get it build with a base tune so it can start then tow it to a tuner who is good with rotarys and microtech. I haven't built a turbo'd 7 yet but i read ALOT.

EDIT: I also heard walbro was good for close to 400 then choke. (dont want that to happen and detonate)

mhh, ive got it street ported with a stand alone and a t4 sized turbo. im not sure what besides my fuel left to do to get that power. but ill be happy with whatever i get im sure. so what kind of injecotrs should i go with. does bosch sell a pump that will mount up? and how much are they ish?

What turbo? T4 is just an exhaust flange. Without knowing the turbo we can't help you.

i think its a s4 tII. it has no manual linkage between the throttle bodie and oil metering pump. but i got rid of it anyway. this build has already got a bunch of crap done to it. (front mount, greddy intake plenum, turbo thats probably to big to spool in a time.) ya it is currently running on stock tII injectors and a 86 NA fuel pump. and i will have it street legal so i can daily it but it will be my track car. im gonna build like a 12a first gen later for a daily

fixit

its a master power, model no. S 70
