Or you can do it like the STS turbo and put it farther back rather than right off the headers. It still works just as a bit more plumbing to do, but its easier plumbing. Yes there are drawbacks but also pluses to that setup. Either way a turbo is going to cost you more than just sticking a plate system on it, if you want to play you gotta pay.

Junkyard scrounging ends up with more time invested for research and making things work. Buying a kit you pay to have someone figure all that stuff out for you. If you arent knowledgeable about how it all works, you can end up costing yourself much more. So pay someone else now or take your time and pay later.

A bud of mine in SC put two turbos on a stock Fox with a 5.0, he couldnt keep a clutch behind it and when it didnt slip he couldnt hook it. There is always more to it than it seems, but you can work up to the next level if you are smart about it.

I'm not boost master, but logic would tell me you're thinking about 'boost' wrong.. It is the positive pressure that is in the intake manifold (one would assume). So if you have 9psi in the intake manifold, you have 9 psi.. It's not like each turbo puts out a specific amount.. For example, if you pump 9psi into an engine, and make the engine more efficient (Breathes better), and everything else remains the same, the pressure would drop (At least, one would assume).

You need to learn more about boost and turbo's before doing this. Carb blow-thrus are pretty difficult to tune (ive heard). I think what you are thinking is just mount some turbo's, run some piping to a carb hat and the car runnin fine. It doesnt work that way. When you add more air you need to add more fuel, and timing. a 255lph single fuel pump will work and its adjustable with a regulater. Blow thru carb set-ups can not be electronically controlled to add more boost at a flick of a switch. Cause like someone else said you have to swap out jets and give more timing. Maybe just wait atleast a year learning more and more about boost. Maybe hang out with some ricers in the walmart parking lot and let them teach you of some turbo's. After you get your **** done, be like "ey... wanna run em?". Use there info against em lol. But then again you are dealing with ricer's... they lie.

2 holset turbos from a dodge diesel are a good size for a 302-351

But you're not understanding what I'm saying.. The psi is the measure of positive air.. So the turbos aren't 'putting out' 9lbs each, or adding, or whatever.. it is the measure of positive air pressure.

So for example, as I said, if you have a turbo and it's making 9lbs in the intake (Not putting 'out' 9lbs), and you make that engine able to take more air in, the pressure in the manifold will drop. It's not like a car battery that can 'put out' so many volts.

It takes resistance to create pressure. So a lot of it is based on the cubes and the rpm the engine will spin. Their is a section under Pipes Boost and Juice on the forum that has a wealth of info. A good place to start if you are interested in turbos. I have a 65 Fastback twin turbo in the works. It will get EFI.
