okay so my supercharger idea is on hold at the moment, in favor of researching a Banks twin turbo setup.  (strange, haven't I been here before?)  anyway.  The system is very compact...but I still would not mind some advice on gaining more room inside the engine bay, specifically on the sides the engine, where the turbos will be mounted.  Here's a few pictures of the setup.

(unsure at this point if I need to buy that EFI package from Banks or if I can just use a different one, like Edelbrock or Holley)

Their website claim is that an intercooler wouldn't be needed up to an 800 horsepower output, but I don't know how much I believe that.  My goal is around 650.  Also, does anyone think those turbos are a little big for a small block?  I got that remark from a friend of mine.

I am particularly concerned with the passenger side...that AC compressor is HUGE and takes up WAYYYY too much room

Can you put turbos on a atmosfheric car with "stock" compression ? Or do you need low compression pistons ???? Or is the turbo pressure adjustable ? because i think with pump gas the max will be 12:1 end compression before detonation ....

just a tought.

not difficult at all to change the compression.  cometic gaskets might be able to lower it enough...if not, I can swap pistons and head.

okay, is there a map or diagram somewhere of a general under-the-hood view of a 1970, that labels the various parts?  I feel stupid right now.

alright, I did a little bit of measuring, and I don't think I should have any problems on the top of the engine.  on the driver side, the steering box is in the way...I've got roughly 4 and 1/2 inches from the side of the block where the headers mount...and the side of the box.  I don't know if that's enough room or not.  However...looking at the steeroids kit, it appears to eliminate that steering box.  That would free up some room, definitely...so...DOES it? from this Vette Magazine article I just read, I really think it does, but it says this bracket mounts in the same place as the old box...will switching to the steeroids kit provide me with more room on the driver side of the block in order to mount that turbo?

also, what is that huge black box on the passenger side underneath that vacuum actuator.  That's getting in the way, but there's a little more room on that side.

and is there a smaller AC compressor I can install in place of that HUGE long thing?

Really would appreciate the help, guys.

I've seen a similar kit...but that kit also increases turbo lag to disgusting levels.

haha. Than you'r back to option supercharger !  

well I SHOULD have room on the driver side.  It's the AC compressor on the passenger side, and that black box, that's getting in the way.  the black box...I dunno, maybe be able to do somethin.  The AC compressor...hopefully get a smaller one, and do some kind of custom mount?  Move it over toward the fender a little more?
