Trying to figure out what I need? Need help please

[rcorte3001]

Hey guys I'm looking at buying a professional products 85 mm manifold and throttle body, this will be going on my 98 ls1 the guy I'm buying it off has the red fuel rails that come with it aswell, now what I'm wondering is what else will I need to make this work ? cause I know it is raised a bit more also what about the fuel regulator ? And will I be able to use my stock fuel injectors still?

Any help would be greatly appreciated!!

I could be wrong, but you might need bigger injectors to assist with the added air going into your motor. I know you will need a tune once everything is installed as the computer will go nuts with the larger air/fuel volume.

Well what about when u convert to a ls6 intake ppl don't always change thier injectors I thought ?

LS6 intake is 78mm if I recall.

your injectors are fine for a mostly stock bolt on car. Have you considered the LS6 intake? People tend to stay away from the aluminum intakes for our cars because they heat sink more then the plastic intakes. Hot intake equals less power potential.
