turbo help

[GM Muscle]

I have a carbed 350 in my 69 camaro and im wanting to run a rear mount turbo setup.. i do have a few questions though.

1) should i go with twins or a single?

2) I currently have a set of stainless works long tubes. i know that the rearmount will take alot of stress and heat of of the headers but i also know the backpressure will generate alot of heat. i plan on running heat extractors through the fenders if that helps. are the flanges and tubes going to be thick enough to take the heat?

3) im also debating on running the inlet back through the interior of the car, through the firewall and straight to the carb. how hot do you think this plumbing would get? i would definately be covering with with some sort of console but dont really want too much heat soaking into the interior.

4) what are the opinions on having a separate stand alone oiling system for the turbo? like a small pump and canister setup? i have some really cool heat extractor tubes that i could use.

I will also state that im not really too worried about any small turbo lag issues or anything like that. the car is a stock weight sbc camaro, probably a 4l65e(shrifter) with a 2500-3000ish stall and ~355-373 gears
the car will mostly be a weekend warrior with occasional cruises and trackdays.. im not looking to make 1000hp or anything. maybe a respectable 600hp. we just put a turbo on my bosses car and its just great, all around fun.

Look back in the project introductions for the turbo Dart. "Deceiver" I think. He did a turbo on it with a carb. But he also has info and liks to other builds on other sites similar to what you are thinking.
Good luck, sounds like fun!

either will work great, though you'd use a different one for a single vs twin setup.

2) I currently have a set of stainless works long tubes. i know that the rearmount will take alot of stress and heat of of the headers but i also know the backpressure will generate alot of heat. i plan on running heat extractors through the fenders if that helps. are the flanges and tubes going to be thick enough to take the heat?

I think you'll be fine with those stainless headers.

3) im also debating on running the inlet back through the interior of the car, through the firewall and straight to the carb. how hot do you think this plumbing would get? i would definately be covering with with some sort of console but dont really want too much heat soaking into the interior.

I would avoid that, no real reason for it, plus you lose the cooling advantage as the air temps will drop as it makes its way back up front. The air temps can be fairly warm leaving the turbo, staying outside the car gives more temp reduction I'd think.

4) what are the opinions on having a separate stand alone oiling system for the turbo? like a small pump and canister setup? i have some really cool heat extractor tubes that i could use.

I'd use a feed line from the engine, one less thing to fail. You'll want to get a good quality scavenge pump though, don't go cheap here; if that fails you'll have a very smoky ride...............

There is a local STS rep located in Arlington I believe. Speak with them/him. They know their stuff and can answer all your questions.
You might want to run an intercooler as well.

They put out a nice product and have the oiling, lag, heating questions all worked out.

Let us know how it works. I have been wanting to put a pair on my 3/4 Ton 4X4 Suburban with a BBC. I pull a Tractor, and a lot of trailers with it, and despite the size of the engine, It could really use a good kick in the pants as I have added a lot of extra items to my truck and it is quite heavy now in and of itself.

Good Luck,

Ty
