Injector size
What size injectors should I use with my HSF-5...........720cc or 780cc? I have a GT35R turbo and want to push about 30-32psi of boost.

Thats a lot of meth nearly 13is gph. I think you should be more around 10gph. 630 is my option. Going big and bigger is not aways the answer. You will have to pull more and more fuel to get your o2's right. So you really want to go with the smallest nozzle you can get all the cooling you need from.

i think they are talking about FUEL injectors. If it were me I would go for the 1000's incase you ever want to do a race gas tune. but if 1000's isnt your bag then 880's for sure. put it to you this way i had 720's with a big ol' M15 meth jet (around 960cc i think) and at 31-32 psi i was maxxing the 720's (106% IDC) and thats at 550whp with a Turbonetics GTK550 witch is close to a 35r as far as flow...
