Welcome over here.
I have seen you over on the other board with the same questions.
It is good to be a buyer now. If you are thinking about this car being you daily driver forget about it. You didn't touch on that over on the other board.
There will be a few who disagree with me on this subject, but since there are so few cars that actually get driven there isn't a lot of feedback. On top of that most older guys who own these cars dont drive them at all and surely wouldn't be here debating about whos car blew it's motor, and who makes more power.
Just like you already know it's the blown 495-510 hp R-codes that are tuned on the ragged edge, that does not mean you can go out and drive the piss out of a straight-from Saleen- T code N/A car either. It's just that the detonation demons usually get the R-codes first.
There are a couple of guys on here that have mid to high mileage on their N/A and blown cars. Some with motor rebuilds and some not.
To be brutally honest, I think you would be better off with an 03/04 Cobra or 03/04 Cobra Saleen. They are out there, just like that one that other guy who advertised to the world that he just bought one and its wearing a KB. The same guy who hijacked your thread.
