I’m looking to get somewhere between 300 and 350 out of my engine. Now I have a street ported engine I am also running a BNR stage 2 turbo I will also be running a haltech e6k ecu. Now something I have been wondering is what fuel injectors to go with and whether or not I will need to get FPR and an aftermarket fuel rail, should go front mount or go with water injection on the top mount, and should I get an aftermarket radiator or will the stock one work? also is there anything els i should look into to getting?

 

with the Haltech, you can run a pretty large injector with out much worry as it can turn down big injectors pretty well. I can just throw out some random numbers for you, but your fuel requirements will be different if you go with water injection or not. For 350 HP, I used 720 pri and 890 secondaries and I had a bit of overhead left.

With a front mount IC, it would be a good idea to upgrade the radiator.

No aftermarket fuel rail needed, I am still using stock ones at 500 HP, but the parallel fuel mod wouldbe a good idea.
