Most people seem to forget about these cars. They can be found CHEAP. Parts are not that expensive...heck, you already have the turbo system in place. Stock motors can handle a good amount of power. Look for a GSX, this is the AWD turbo.
Just like to say that me and Silver posted some cars to tracciontrasera, he posted his 59 Impala, and I posted my 30 Model A Tudor (mostly because its questionable about permissions not fully being the original authors car and such so no links to either car for permission reasons).
