ah, thank you guys for all the tips! just to clarify a few things, I already have a turbo laying around, one out of a 1.8 litre subaru, and those were supposed to make boost around 2200 RPM factory. I bought it for $10 just to dick around with, the engine was toast, as were about a half dozen others in that same yard (all from the same family, died of no oil...) the turbo was siezed, so it was just a nifty paperweight. turns out, the same dipstick that ran it out of oil put RTV in the compressor turbine, so evidently it never ran for most of it's life if at all! so, now I have a perfectly good turbo laying around, some spare manifolds, and now a perfectly good holley 1904 glass bowl to go with it! so, this project is a "why the heck not?!" thing.
