Default Budget turbo build input wanted.

In the future I plan on using a 1976 455 olds in a build. What I would like to do is put a turbo on it for a little extra hp. SO... I need some input. I want to do all the fabricating myself and not buy anything that I don't have to. So that means using a used turbo off of something. Or two turbos off of something?

Anybody have advice on selecting a well working turbo set up?

Advice?

Two turbos will work much better than one big turbo. Turbos for 4cyl engine work good. There are a lot of the 4 cyl diesels out there. Lots of new turbos on Ebay for sale.

A turbo hanging off of each side would have to look cooler too!

Hope you do a build thread when you work this out. I'd like to see how it's done...

I'm not sure the term "budget" and Turbo belong in the same sentence.

go to eBay and type in "turbocharger books" and it will bring up dozens of new and out of print books on the subject.

DO a little math and find out how much CC or CI of each bank on the 455. Then go looking for a factory turbo 4 or 6 cylinder with about the same size as your 1/2 of a 455. Grab 2 and go! Lol

I've been patiently waiting on you to reply lol. Do you know of any turbos to steer clear off? Ones with oddball flanges or anything? Non rebuildable ones?

I also have a 440 Mopar that I could do this too. Or a olds 307, or a Pontiac 316, or a run of the mill sbc. All of witch I hold at very little value to me if they grenaded.

Cool

Well, I'm partial to the Garrett T3 turbos offered by Ford on the TurboCoupe's and SVO Mustangs but their little 4cyls are 140 ci x 2 would only be 280 ci. You probably need something bigger. Some of the diesel turbos may work.

If you were going to run any of the smaller motors (307-350ci) then you can run 2 Buick Grand National turbos. They have the waste gate built into them and most guys step up to a bigger one. If you are patient you can score them for around $200. If you are going to run the 455 / 440 then pick up a couple of Master Power T67 or T70 with a T4 exhaust flange. They are brazilian made and good quality for the money (Around $600 brand new)
