Over the last 2 weeks, Ive been trying to get this turbocharger either from my classmate in college from off a Ford Probe GT, this turbo from Ebay from off a Benz for 40 bucks, or this junkyard turbo from off some old 18-wheeler/generator motor in town. Ive had this idea before about turboing my Nova, and adding a mid sized cam in it, and the numbers and all turned out well. But recently, I herd my instructor say that It may not work, or it may cause problems with my motor and mess it up. So that eans all of those nubers are wrong. The motor is a 307cu chevy (not Oldsmobile) V-8, which had a 2 barrell carb, a intake with small runners (I was told that they were made to make more low end torque) and a pair of 58cc heads (i think) with 1.70 or 1.75 intake valves, and 1.5 exhaust valves with flat top pistons that have four valve releafs in them. I was planning on changing out the small heads and intake for a pair of heads from off a 305, which have 1.90 intake and 1.60 exhaust vlaves, but have a 64cc head I think, and that may effect my compression ratio a bit. And I was gonna add a 4 barrell intake from off a 350 chevy, and a square bore Eldebrock 4 barrell on a adapter plate to allow it to bolt on to the quadrajet intake bolt pattern. The engine, I guess, originally had a high compression in the low 10s or soo, but if I change the heads, then it'll probably drop, which is perfect for a turbo because i herd they work best with a lower compression. Now, this is where things changed. Our instructor told my and my friend Alex (who was also looking to do the same thing as i was) that it may not work right, or it may mess up the engine because normally engines has flat top pistons, and not dished pistons. And that they also have those valve releafs in then too. I began to wonder why would they do that, when ive seen numorous people use superchargers, both roots and centrifigal types on cars and truck, and I never herd of them using dished type pistons before, then again, I could be wrong. So I when back, and I ran thru it again, and from what I have come up with, it ought to be possible. But I think I also forgot to take in consederation the psi of the turo itself. The Probe's turbo probably put out 8 to 10 psi, the Benz's was at 14 to 17 psi, but the junkyard turbo from the cummins diesel, if restored, could probably put out anywhere from 25 to 30 psi!!! At that psi, if I floored it, it might blow out my freakin' head gaskets, or do more than that. So now, Im gonna do more research and try to find out more about this, cause at nothing worse, is having your car's motor let go while your pawning this guy in a cery red Honda Civic.

On another subject, Ive also planned to either turbo or supercharge a 5.5 horse tiller motor on a go kart, or make a turbo jet engine from a junkyard turbo on using junk parts. How it'll run? I dunno. What to put it on? I home made gokart frame, of a mini bike frame would do because there light. And I may even considering trying to make it work in a similar fasion to a turbo shaft engine found on all helicopters to add a pit more performance, in that it'll drive the rear wheels instead of providing trust to push you forward. Heh, I'll try to get the demensions and numbers down late on when I have some time aftre class or when Im a home.

If any of you gearheads out there have any insight on this, please let me know. I'll read this when I get back on Friday.
