Post turbos on a olds 307ci 5.0 "87"?

i have a 1987 cutlas supream. therein lies a 307ci
normally aspirated. i plan on adding two junkyard turbos wich i found in a couple of volvo's i believe they run between 5 and 18 psi of boost
i wanted to run them at 15psi each putting me at 30 lbs of boost
more than doubling my hp. no intercooler though
the air will be drawn directly from outside the engine bay via the hood or head lights spot.
does all this sound like a good idea.
ps i know i must prep the engine with forged pistons ,rod and crank, sound like there is anything missing???

Thumbs up

I would not personally run those at 15 ea. A lot of people believe that two is better than one. Not always true.

As for the turbos from the Volvo's = JUNK turbo lag, turbo lag, turbo lag!!!

30 lbs. of boost = NO WAY IN HELL

As for you stating that the air will be drawn from outside the engine compartment, IT DOESN'T MATTER. Turbos are obviouly run off the exhaust = HOT AIR. Run an intercooler, although you don't have to. Turbos get up to extreme temps., likewise the air they shove in. There is no way completely around it. Intercoolers help considerably.

I had a turbo car. It was a Turbonetics T04 Hybrid, capable of putting out up to 32-34 lbs. of boost, ran it at 25. Awesome power and slight lagging, not noticable.

If you want a turbo car, do it right, you will be much happier.

Good Luck, Jason

find a better engine
307 olds didn't have that good of air flow
Instead of getting all turbo up on a olds find a better engine
I have a 350 olds bord out and stroked out to a 425. And it looks stock wich makes a really good sleeper.
Good choice with the oldsmobiles though
there aren't many out their that want to mess with them but when you know what you are doing you can kick some serious *** !
Chevys are a dime a dosen

have fun
