Ive seen a few turbo shadows, theres that noisy criket daytona thing. . . but if you want fast for under ten k then you should buy a plymoth laser. just dont tell any one its got a mitsu engine and you can pull 500 all wheel drive horse power good for tens and ethonal friendly, with a bigger turbo, injectors, new ecu, and even a gm maf. 80s gm sounds easy though and less hate mail.
Have you checked out Allpar.com or MyMoPaR.com they have or at least use to, some good tech articles for these Laser's, Daytona's, Lebaron's & Shelby's...
