Exhaust/ cam question with sts turbo kit
I have a 97 vette with h/c/I. I'm looking at putting an sts twin turbo kit on. I'm running tsp long tube headers with off road x-pipe. Can I keep the headers on or should I put my stock manifolds back on? The cam that I have is a Howards Asa cam 226/236 .525 lift 110 lsa and I don't know if this cam will work with boost. I'm only looking at running 8 to 10 psi. I'm kinda new the the forced induction so any help would be appreciated.

I will always try and run stock manifolds on a turbo setup. They support plenty of power and won't leak or crack.
Instead of doing a sts kit I would have a custom rear mount built with a 76/75 turbo or a A&A kit.

Since you already have the headers, you could keep them if you wrap them [radiate a lot of heat] but TBO they wont do that much for you. You could sell longtubes to offset the kit cost and go with stock manifolds. I run stocks, stage 2 engine will have SS shorties
I dont think that cam would be a good choice for rear mounts. Too much LSA and duration. It will be a dog until it spools up. Comp makes a couple grinds specificly for rear mounts with a reverse [I>E] pattern
If you can get the Long deal on a used STS kit go for it.Mine has worked out well, very drivable. But if you are looking for ultimate power or lowest cost look elsewhere. A turbo setup will be more costly and nicele and dime you to death.The STS installlation is complex but will save a lot of fabrication. However, invest in a turbowerks return pump from the go. Be aware that the turbo type and size varied with what was available. Last I heard STS had gone **** up.

I just read that they went under also but the original owner bought it back and is planning on starting it back up.

I think youd be hard pressed to tell a difference in this application between LS1 and LS6 manifolds.
"Stage 3" is a nebulous term to define turbos.As always it will come down to housing size, A/R ratio, ect. Keep in mind bigger isnt always better, especially when it comes to rear mounts which seem to be even more finicky about sizing. Before you buy the kit, get the details on the specs and check with a knowlegeable person. Replacing the wrong sized turbos with quality units [and BTW if they are heathen Chinese knockoffs, run]can make what seems like a good deal a pig in a poke.Also, make sure you check the turbos for signs of blown seals. The early kits were notorious for scavenge pump failures leading to ruined seals that will rain oil. Later kits used two pumps.
