Got ripped off. Looking for a new idea for the inside of the engine. Stroker maybe?

That advice is valid and makes a lot of sense, except, he wants to have air-conditioning, and power steering on this car, and space is at a premium in the engine compartment for an A-C compressor and a power steering pump AND a turbo, a wastegate and all the plumbing that goes with it. Packaging all that stuff becomes a problem.

There are many rear-mounted turbos being used, successfully, (a whole cottage industry has sprung up, offereing kits for these,) and while they really do have the problems you pointed out, they work... obviously not as well as an engine-mounted system, but they DO work. Having one of these in place would still be more desirable then building a naturally-aspirated system, I think.

Just my 2-cents...
Roger Bill..... having raced a turbo car for years in rallying, all I can say is that turbo lag sucks! Getting the CR right and the right turbo impeller and size (i.e., not too big, and keeping it all tight, with a big exhaust pipe can make turbo lag go almost totally away.

The J-pipe shown is very nice and easy to fabricate, but turns in the exhaust side INTO the turbo can be a LOT,LOT tighter than that shown in the J-pipe pix, and it will still work fine; you can do 90 degree turns in an inch and it will work out. So the package can be made a LOT more compact than the setup shown. And the AC can be put up higher; not sure which AC package that Chuck is looking at but the Sanden type compressors are pretty small.
