Al right guys, I am thinking about putting a turbo on a non turbo motor. I see these piston guys running 22 psi booston on 9:1 compression motors. I was thinking of taking this '88 motor I have started to build and slapping a mid sized twin turbo from greedy or some other big name. I was thinking of about 14 - 18 psi max, with stand alone managment, a very larg street port, exhaust, yadda yadd yadda. My mane concern is the integrity of the rotor housing wall. is it strong enough to handle this settup? Or is it the seals I should worry about. I know I will have to runn higher octane fuel and I was thinking about the water injection form Edelbrock and timing control. Also thinking about nitros, but that may be too much. My goal here is about 500 BHP and still be driveable.
I only just got the motor the other day so I have some time to plan.

hehehe...you called it greedy...it is true...waaay overpriced.

You would be *much* better off buying a blown motor out of, or an entire, turbo II for your purposes. You will need most of the pieces out of a turbo II anyways to make this proposition economical (exhaust manifold, intake manifold, tubing, intercooler, etc), so you would be much better off, IMHO, getting a turbo motor and dropping it into your car. You should do a basic rebuild while you have it out (rotors, housing, apex seals, motor bearings and gaskets), and, unless you have biiig $$$, using the stock ECU out of a turbo II and either chip it, use a piggy back fuel computer, or, preferably, both. Even though an engine management computer will cost you $1 to $2 g's initally, you will spend easily another grand wiring it up and installing sensors (this is true for any car except OBDII gm's), and several hours of dyno time tuning it (at least another thousand, give or take). I will give the same answer I give to the people on the 944 boards I write on asking how to turbo their cars...the answer is simple...sell it and buy a turbo, or do an engine/ecu swap. Any other way is not economical and counterproductive...you would be trying to reinvent the wheel. Oh, and back to my first sentance...you are going to save a lot of money using a generic turbo and adapting it to your needs, like a garrett hybrid...my personal favorite...$1000 for a custom trimmed T04E, and a couple hundred more for custom flanges and piping, as opposed to $2500 for a "greedy" turbo...besides, greddy uses garrett internals anyways. Going name brand is not always the best choice for performance (all though garrett is THE name brand for turbochargers, just a lot of companies buy their parts and way overcharge for them)
