LOOPY309: do you plan on installing the turbo off on only one side (left or right), or somehow installing a Y-pipe with the turbo downstream?
Here's an idea for ya, have you ever looked into the remote mounted turbo setup? STS Turbo has a pretty genius design that works great. I have one installed on my 99' Camaro SS. Freakin' thing burns the tires off the rims at only 9psi of boost!! A good friend of mine liked my setup and decided to mock copy the design himself by getting all the parts individually. In the end, it saved him around $2K from what I paid... which upset me quite a bit, but good for him. If you're concerned about space, I would think this would be the setup for you. Here's the site: check em' out. http://ststurbo.com/

If you have questions, feel free to ask away I'd be more than happy to help.
