    Does anyone know here if there is a turbocharger available for 305 or 350 SBC out there? Could another model diesel be adapted to fit?

    There are turbo kits available. Check with <a target="_blank" href=http://www.innovativeturbo.com/>http://www.innovativeturbo.com/</a>. Someone brought the same question about the diesel turbo up on another board. I asked my father who designed turbocharger for Garrett in LA and he said that the Diesel won't offer much gain to a 350. Your best to get the correct turbo if you want to see all the benifits. GM did make a turbo Trans Am in sometime in the late 70's early 80's. If you could find one of those in a junk yard, you should be able to use that set up.

    The early 80's turbo ta's are pretty crappy. Not much to be gained for your efforts. If you really want forced induction for your rig, it would probably be easier to go through some junkyards looking for a 6-71 or 8-71 blower. Buses commonly had these and sometime they hold a treasure untouched.

    <a target="_blank" href=http://www.cartech.net/>http://www.cartech.net/</a> he has drifted to Miatas and imports unfortunately

    a little Holley owned Weiand or B&amp;M blower would be a cheap way to go but none will touch a turbo system

    what happened to TurboTechnologies in Tacoma WA? they did a single turbo 80ish chev shortbox

    Old city buses were especially good for having these. They aren't the easiest find and sometimes the units need so much work it will cost what a refurnish one will, but they out there. Just might have to search some obscure and far out yards.

    What the heck are you talking about??? If you are talking about me saying a supercharger would probably be easier... it would be IMO. At least for a custom setup. You are gonna have a lot of tubes to fab up if youw ent with a twin turbo setup, even a single would have a fair amount. Also sometimes the wastegates cause confusion and problems for people. I have owned two turbo cars, and do a large amount of work on a wildly modified 98 GSX, so I am at least semi-familar with them.

    A supercharger is easier since it has no extra pipes to fab up exhaust and no modification to the exhaust to install it. Sometimes the oil line can be a PIA, but there are self-oiled units that you just changer the oil on. Hood clearence you could throw out if you look at roots style blowers... the cent's will fit under you hood no problem though.

    Overall it depends what type of guy you are... both would be a blast for an mid to upper end kick.

    But even a supercharger or turbo kit doesn't fall on either /forums/images/icons/wink.gif You still need motor mods ovbviously. Fuel system upgrade mostlikely, and numerous other things.

    My point was that you can find these or can sometimes find these in working condition or rebuild them for far less then a new supercharger or turbo. Heck even rebuilt stock ones would be cheaper...

    I'd be interested to see if anyone has a "kit" for the turbo. I assume someone would have to have one for a sbc. I'm curious what one would run. What would be the cheapest route for a "bang for the buck" turbo on a sbc? If you can show me a turbo setup without major fabrication of pipes and exhaust that will make about the same power as a rebuilt stock supercharger MJ, I'll give ya two thumbs up and a pat on the back because I would of taught me some real good info there /forums/images/icons/cool.gif. I haven't been real up to date on turbos on a V8, but I know a few years back it was way more expensive. But since you are more up to date on technology of the turbo... have things come down in price that much? A new low-buck idea out?

    I cant find anything for SBC.
    fords there are several sites with homebrewed twin turbos.
    simply flip the factory 5.0 headers upside down and add short length of exhaust pipe to adapt junkyard turbos.
    exhaust piping doesnt seem like major fabrication, any muffler shop can do it, but I will have to try it before I can say for sure.
    hardest part is choosing what turbo you want to run. that is a chapter in Corky's book, reading compressor maps. then it come down to fuel systems $$$

    the little roots supercharger kits are under $2000 in the summit catalog and for mild under 10# no engine mods should be needed.

    No sbc's huh... I also guess I would like something a little sturdier and heat resistent/insulated then plain ole exhaust tubing, but it would work. Some cool links.

    well if you have a 5.0 ford and $4000 you can look at Incons complete kit. real sweet cast manifolds, super $$$ state of art turbos. everything down to nuts n bolts to bolt in 400+hp.
    these guys break the factory blocks with ease around the 600hp mark.
    I think he delved into the LS1 crowd but I havent looked there yet.

    I used to own a 87 Buick Grand National (GNX) Twin turbo, with all the Kenny Bell aftermarket mods. Turbo's are okay for mid to high RPM horsepower, but I really think you'd be much better off with a supercharger. My father had a 49 Plym with a supercharged 426 Hemi. That was one powerfull car. SUPERCHARGER is the way to go. Paxton does make one for the SBC.

    What he is saying about the turbos is true. If your looking for low end power, a supercharger is the way to go. I have seen photos of a Ferarri once that had a supercharger that cut out after a certain RPM and then twin turbos would kick-in!

    Hey, Z3PR, my dad designed the turbo for the Grand National. We had the first prototype back in '82 (dad had prototypes of just about every turbo car produced with a Garrett Turbo.) The first one was a lot faster than the production cars too. Was yours just a Grand National or the GNX? The GNX is worth a small fortune now! They only made around 600.
