720's and 1600's on a stock port S4
I wanted to know what you guys thought about how my motor will run if i run 720 primaries and 1600cc secondary injectors. The motor is a stock S4 TII motor. To4e, Haltech E6S-8, FMI, 3"DP, 3" exhaust out the back with a hi flo cat, HKS twin power ignition box. Is it gonna run or crap out, I would like to run about 18psi boost. let me know what your thoughts are.

I think the injectors will work fine, but I think it is going to "crap out" if the engine is just a worn stock block. Most people only run about 12-14psig on the T04E series turbos.

One more thing, since the motor is fresh with zero miles i have put the 720 in the primaries and have 550 sitting in the secondary position at the moment. This is for break in, but once i have a few miles on the motor i plan on swapping out the 550's for my 1600's

I am running 720/1600 in a s4 block. I have already completed my breakin. I would suggest using the stock injectors until the breakin is complete. I have been messing with my haltech e6x and I have been flooding out the motor. I wouldn't want to do this to many times on a fresh rebuild.
