You don't owe anything, save it for your drivetrain, you'll need it.

Once you add a turbo into the equation it becomes pretty easy to make big power, a good turbo system is not cheap though, when you figure in the new injectors, fuel pump, exhaust, intercooler, turbo, plumbing, etc. it can cost you more than the original engine (which is why I think a lot of people avoid it). No getting cheap on your turbo system and picking the proper components is just as important as picking proper components for your engine- if not more so.

What hotside do you have on your turbo? You may need to keep a look out for something different depending on what you have. Your cold side is really more suited for 550hp, but if you do a good job on everything else and run a slightly large hot side you can probably squeeze out 600hp.

i looked at that last night and i dont see any #'s. it has two ports on it if that means anything. the guy i got it from just told me 77mm what ever that means. turbo's aren't that expensive so i was thinking I'll use this one as mock up and buy the time this project is done I'll be ready to buy a better one. i had someone else tell me this turbo might be a little to small as well.

i know the paint job is out there lol but this is my other camaro. i stripped it, painted it, and built the motor. its pretty fast, i can lay 138 ft of rubber with both tires. this next one is going to be a little more mature.. something I'm not embarrassed to drive around town in lolol the green car started out as a car for my daughter... now she wants a truck so i took over the green car.

You need to measure the AR of the exhaust side, a larger AR will help give you more top end hp but will reduce your low end torque, since this turbo is on the small side on the compressor a slightly larger AR on the exhaust side will allow for better exhaust flow, requiring less boost pressure for a given hp output.

A LOT of people are not aware that the exhaust side is just as important as the nicer looking intake side. Also, what are your wastegate dimensions (if you have one already)?

This turbo uses an A/R system for scaling their housings, If you google "how to measure turbo A/R" you should be able to find a basic guideline how to do it.

Here is a link to Garrett's site with some decent turbo info-
