Question about injectors for a boosted 3.4 dohc

I've got a turbo lq1 I'm putting into a Fiero and have been trying to find injectors. I was wondering what injectors to run and where I might be able to find them. The setup I'm planning on running is 10-12 lbs of boost with a T3/T04E 60 A/R turbo on a stock motor with ARP studs on the mains and rods.

I'm doing something similar in my LQ1 Fiero. I've got a GT32-76R and the calculations I made said I needed 42 lb injectors. I got a flow matched set of Bosch injectors on Ebay for a decent price.

42.5 lb/hr injectors will max out around 400 crank horsepower. You should be close, but likely okay.

i have the 42.5# injectors for a 3800 in mine. You can use the same injectors or i think they have 65# ones as well. I got mine from ZZP. Keep in mind you have to tune the ECU for the injector size. I converted from OBDI to OBDII (1996) with DHP. DHP is no longer around so if you have a 5spd trans you can do a 1997 harness and ecu and use HP Tuners. HPT doesn't support 1996 LQ1/4T60, and the 1997 ECU uses a 4T65 trans... but is tuneable with HPT. If you have a 1991-1993 LQ1 you can burn a custom chip.. 1994-1995 LQ1 is from what i understand not as easy to make a chip for... Hope this helps.
