I'm trying to figure out what size/style injectors I should go with.

I have an '04 LQ9/T56 going into a '67 Camaro. I'm doing an H/C/I swap, and will probably be looking at 450-500rwhp. Intake is an Edelbrock Vic Jr. EFI, so I think that means I can use standard or Pico injectors. Right now the LQ9 has whatever it came with (stock) injectors.

The fuel pump will be a Walbro 255 liter/hour or possibly a 400 liter/hour pump (overkill?).

What size/style injector is recommended? Is it possible to go too large on the injector? I don't plan on spraying this motor, or going FI in the future, so I won't need a ton of room for growth. Thanks.

 

bump...

Would 32lbs EV6's be a good choice for my application? Or should I go with 39/42lb?

Are all EV1/EV6 injectors the same length? I have seen some listed as long style. Thanks.

 

give a call to Fuel Injector Connection - FIC

The 32# would suite that power level fine. I would rather put in some 36# or 42# just to have a little breathing room though and they would run fine.

 

if you have the lq4 wire harness you will need to adapt that. i would put in a 42lb ev6 bosch and splice in the pig tails

 

Thanks for that. Green Top or Green Giant?

I'm having a custom harness built, so they'll build it for whatever style injectors I choose.
