301 Turbo on other engines
 

I found a rebuilt factory T/A turbo for too good of a price to pass up. Seems like it’s in really good shape, seller claimed it had zero miles.

Main question: has anyone ever ran one in a draw-thru setup, but not in a factory configuration? Seems like the turbo qjet and adaptor are expensive and hard to find.

I was thinking of fabbing up an inlet adaptor for a holley, and running it on an old straight 6, perhaps even on my 326. Do you need to modify the carb to work for a draw-thru setup?

I suppose it could be run in a blow thru setup as well.

Is the juice even worth the squeeze? Or should I just sell it to someone with a Turbo T/A?

On a Draw Thru Holley setup, it should act just like a Holley on a NA application.

Do you have a picture of this turbo?

Lately I have been seeing a lot of Buick 3.8 V6 turbos that people think are for a 301. There were a lot more Buick V6s made than 301 Turbos.

I specialize in the 301 Turbo engine and make performance parts for them. If interested, take a look at my website.

Thanks Tom. That makes things much simpler.

Cool shop you have. Ive browsed before. Thanks for providing good products for the community.
Anyway, here's some pics:

It does look like a 301 Turbo.

It would require a lot to adapt it to a conventional Pontiac V8 and honestly, the turbo is too small even for a 301.

I have seen it used on a OHC 6. In fact there was a car featured in Poncho Perfection with one on a OHC 6. I think it was in an Astre.

In all honesty, for the amount of fab needed to use this turbo in a custom application, you are better off buying an aftermarket turbo for whatever engine you want to turbocharge.

"Skip" (Dudley) McCully and I had several conversations about installing two 301 turbos
on his 455 Pontiac vehicle. Told him that even with two of them the engine would be under-powered.

Ken Crocie did a HO Racing Turbo set-up and it was written about in several magazine articles.

Ken later did a Turbo upgrade/installation for a customer using a larger aftermarket turbo. (Written up in either Car Craft or Hot Rod Magazine. It made around 700 hp if I remember correctly on a 455 engine. Still a Blow-thru car/bonnet deal.

Ken C has been involved in a bunch of magazine articles over the years.
Once he figured out how to add the correct amount of fuel to the engine it had a decent hp on one turbo. The turbo was NOT a Rajay 301 turbo.

2 of them on a 455 can make about 800hp in a draw through setup. Done and proven. The correct qjet for this turbo has a boost referenced power valve. Using a random Holley carb will not work correctly. The Pontiac 301 turbo has a .82 ar turbine housing. The similar Buick turbo is smaller.

Is that twin turbo build anywhere on line. I’ve always wanted to try it and would be cool to see one done.

Interesting, makes sense that the carb is set up similar to a supercharged application. Would a regular holley supercharger carb be the simplest way to go?

Interesting on the QJ. for the 301T . The 301T that was apart (top end off the ling block) when I bought my 81 had a Holley 3310 on it i guess the previous owner used. maybe ran like crap is why he started taking it apart. Has head studs and supposedly an UD cam in it.
