I always like the turbo idea and it is a burning desire to build one. My LS1 in 67 Camaro has 28.000 miles and in stock trim. If I build a single or twin turbo what horsepower gains I can except and how much would cost?
Any ideas where to look?
Thanks

Depends on your fab skills, but I've heard of doing them for $3K to $4K if you do all the fabbing, and use stock manifolds, maybe a factory turbo, etc. A decent kit is $5K but nobody makes one for your specific combo, so expect to pay more if you have someone custom fab something. 800-1000 hp is not difficult to make with those setups. A twin turbo with small turbos on a stock LSX will makee 500-550 rwhp at only 6 -7 psi so there's a ton of potential.
Can you weld? I don't think they make any kits for a 67 Camaro. I'm making my own for my turbo LS1 67 Chevelle. On a stock motor is you just want a turbo and no intercooler you can run maybe 5-7Lbs of boost with all the stock fuel stuff but it will be pushing it. Low end, maybe $3k up to $5-7 depending on what else you decide to change. The figure $500-1000 for the turbo, 500 for wastegat and BOV, then all the little things start to add up...piping, clamps, silicone hose, exhaust manifolds...
As for power with low boost 450-500 maybe. There are a lot of variables
On a stock motor you can safely run 8 psi or so on pumpgas with an intercooler. You can do a twin setup for about $6k or less. 650 hp at the crank is a good safe power level on the stock motor.
Look up my car for a good place to start, that will show you the basics of what you will need.
When you blow your engine, you will just have to build another with forged rods and pistons.

You can upgrade rods and pistons along with some fuel system upgrades and get even more power. My plans are to take my stock LS1 and upgrade the pistons and rods and shoot for 650 wrhp. The stock crank is said to hold 800+ HP without any problems but the rods and pistons are not up to par.
Im still a good ways from building the tubo setup but I have lots of ideas. It would be nice to see someone else go through this before me so I can see what kind of problems you run into. LOL
Thanks for the all info. So if we are looking around 500 horsepower on a stock motor, ( thats the limiting factor damn it) that would be doible with the head and cam combo the conventional way. I have to think and decide.
I think doing it the right way starting building the engine for turbo and the twin system is the way to go.
If you only want 500 hp at the crank, go cam and heads. If you want more power by turboing it, Leave the cam and heads STOCK. You can make 650 hp with turbos and NOTHING else. If you forge the rods and pistons, you can make 800 hp with the rest of the motor being stock.

Are you serious about 650 horsepower without doing nothing to the motor?
How much risk involved to have that kind of power on stock engine with turbos?
Thanks
That's the max power it will put down with a GOOD tune and be a great weekend worrior. Alot more then that you will likely snap a rod. But yes, all stock. Don't even have to open a valve cover!
If you want it to last 150k, I would keep it around the 600hp level and you won't ever have to worry for the life of the car.
These motors have made 800 hp without opening a valvecover, but that will NOT last very long.
