is this similar to what youare talking about? i couldnt find the exact one but this one seems pretty similar On 3 Performance 76mm Turbo Camaro LS1 LS2 LS3 LS6 LSX Camaro Trans Am 6 0L 5 3L | eBay
also, am i right in thinking that typically the lower the ar exhaust the quicker the spool?

Do you have plans to strap the truck on a dyno and shoot for 500 rwhp?
I wouldn't worry about rwhp numbers. I suggest you put on a good sized turbo and adjust the boost to your liking.

Yea, thats just like the one i mentioned, but 76mm compressor. You might have to run a smaller turbo at higher boost to get what the power you want and still have fast spool. And yes, lower A/R equals quicker spool.

I think im gunna start with the turbo i posted and go from there.
I do have plans on putting it on the dyno but like you said ill play with it to fot my needs best. Having it be 500rwhp would be cool but this will see many many miles

well this is gunna take longer than expected, life got in the way with some un expected bills oh well itll give me more time to figure out what i want.
i thnk im just gunna get that 76mm turbo with the .81 A/R. im more concerned with low end than top and if it doesnt work itll give me a better idea of what i want then i can spend the good money on a good turbo.
on to the next thing, wastegates. can i get by with just the normal 38MM gate? or will i need to go bigger?
and iwould like to have a manual boost controller, or would an electric one be better? i really wanna keep it as simple as possible.
thanks for all the help BTW, you gus are awesome!

I'm running this controller in my truck: Hallman Evolution Kit : BoostController.com LLC - America's Source for High quality turbo boost controllers, silicone hose, and more performance products - 877-836-6155- precision boost control. Turbosmart Warehouse Distributor
If you want 12 psi MAX, then run a 6-8 psi spring. The boost controller will allow you to double whatever spring you have in the wastegate.

think i have the turbo stuff figured out. now i need to figure out my fuel system
for some reason i cant remember for the life of me what pump i put in the tank and i cant find my receipts. im pretty sure that its the walbro 255 pump in the tank with the corvette fuel regulator on the frame rail. i know i need bigger injectors but will my pump support the turbo and still have room left over? if not my buddy will give me his brand new aeromative 1000 for $200. will that be better? he doesnt want to hold onto it for too long so i have to make a decision pretty quick.
i have 1 more payment for my trans then ill start buying a lot of the parts. i hope to have this thing boosted by the end of summer!

Good to know that either will work. I'll look for a 44mm just to be safe though.
Any recommendations for manual boost controller? I'd like something i can control from inside the cab. This one looks cool, but its pricey!

You want the WG spring for the LOWEST boost you want to run. Boost controllers can only raise the boost. They can not lower it.
