Kind of a noob question about the pontiac 301 turbo
Does anyone know if they have similar flanges to any other turbo in any other car or that are sold anywhere? I am having issues trying to find a turbo for a turbo 301 motor I just bought. The guy kept the turbo which is fine the seals were blown anyways. I have looked tons of places for this yet can't find any info and/or turbo's. Anyways anyone know where I can find a turbo from another motor or from a company that sells new or rebuilt turbo's for this motor?

Re: Kind of a noob question about the pontiac 301 turbo
you suck. I just gave away an old TB0305 for an 81 TTA like three months ago. Perfect condition with less than a week of use (in the 80's). A guy I knew bought it new back in 81 from GM Parts as an easy way to get a bigger turbo for his blow-through 79 Mustang turbo 2.3 (which he promptly crashed at the track). The early Ford and Pontiac turbos are almost the same, except for the hugeness of the Pontiac piece. I had that heavy piece of ---- in my closet for like 5 years. I gave it to a friend who's got a compound-turbo Jetta. Sucks to be you.
You don't want those turbos anyways. except for concourse show-cars. Shitty compressor design, shitty turbine, shitty mounting, shitty 70's technology. All around fail. They are basically the earliest ancestor of the later T3 frame. The bolt patterns are all retarded, too. Just buy a dirty cheap T4 or something cool, like the Holset VGT that one DSM guy here is running. All you need to support is like 200 hp. That's all the stock Turbo Trans Am made back then. Hell, they broke a lot at those power levels. The suck-through carb/turbo thing is a shitty all around idea. The fuel pools up in the compressor and good fuel distribution is impossible.
Take the small block advice from CspecRun. The 301 was a poorly concieved Bolivian ***-chowder of an engine. I'm sorry if that hurts your feelings, but you need to hear it sooner or later (preferably before you throw a bunch of money at it). If you need to throw an engine at a 301 car and you really dont want to change mounts and transmissions, you can always use a 350 Oldsmobile or 403 Olsmobile. Out of the Buick-Olds-Pontiac trifecta of suckitude, the late 70's and early 80's Olds motors were the least offensive. And they're cheap (ish). Just don't go turbo one of those. They'll pop head gaskets more often than I pop wood (at least 3 times a day, in case you're wondering). The early 70's and older engines from those three companies are ------- expensive. Probably worth more than any car a 301 came in. Sorry again.
If you want to be extra-bawler and you already have a running (!) 301 with a bad turbo, use this opportunity to fix what Pontiac fucked up on. Spend a few hundred bucks on a Megasquirt and 8 used injectors, learn how to weld injector bungs onto that cast-iron heap-of----- intake the turbo 301 has, and get a real turbo on that motor. It has no compression (like 7.5:1), so that's good. The biggest problem with these was fuel distribution with that suck-through carb. Do away with that and you might have an engine that sounds good and makes the same power as my stock 08 Si. Unfortunately, like the fat-assed Si, the 301 will never be fast on a budget. It might be faster than it is now, but there will always be some fucktard in a turbo 89 d15 heap that smokes your *** like a QP of purple. Wanna be faster than that porch monkey in the $400 89 hatch? Throw a small block Chevy in your ---- NOW!

So, what the ---- are you gonna do with this bitch? Curiosity is getting to me. And where the ---- did you dig up a turbo 301 anyway? Mexico? China? A Bolivian's mom's ***? Unleash your knowlege, beaner!

Re: Kind of a noob question about the pontiac 301 turbo
Beaner? funny. actually I wasn't lucky enough to find the 301 t/a I found and bought the turd of all turds when it comes to Trans Ams. I got the n/a 301 turbo. I am just looking for a relatively cheap way to add power quickly, and I am guessing it would be relatively cheap to swap over the turbo setup from a 301 turbo. But I have thought through every motor combo you could think of. I am just looking at every option I can before deciding.
So far it has pretty much boiled down to:
383 stroker
400 small block
turboing the current turd
buick 350...heard they put out mass amounts of torque back in the day.
