ya.. Im going to GS Motorsports in Irving in a few days. Went to go check it out friday. German, the guy who owns it seems to be really kool and he knows wtf hes talkin about. If youve heard of the team 16Niss, GS does most of their work I think. Its like the most renowned car club/team in dfw i believe.He told me he could prolly have my car running in under an hour... They specialize in Nissans, which is always good.

there is also Matchless Performance, havent heard much about them, I also havent personally been there.
I have been to Intercrew, know 2 ppl that work there, but after all the **** Ive heard, i cant honestly say Id be comfortable with them working on my car.
Dont really know anyting about Jotech..
hoped that helped some. Although, I would not take my car to a shop based solely on what others say. Id have to go visit and make my own impressions.
