Best shop around if you drive a mustang had my 16 GT pushing 700hp comfortably. But plan in advance them being the best means they are always busy and you’re gonna have to schedule something, but worth the wait.

Great friendly staff. They pretty much do everything there. From minor repairs to major engine swaps...and anything to do with performance. They do it there!

Hands down the best shop in CA. Covid kind of screwed me with timing and parts on back order but as soon as everything was in, it took them 4-5 days for a motor drop with a KB supercharger install. Couldn’t be anymore excited and definitely will be with these guys in the future, THANK YOU GTR!

I have a 2006 Mustang GT that I had GTR put a Kenne Bell Stage I along with suspension upgrades. Ran great for seven years not an issue. Finally decided to rebuild the engine instead of putting in a new Coyote motor/ transmission unit. Gonzalo gave me the recommendation to rebuild the stock motor and keep the transmission I already had that had just been rebuilt. Took them over six months to even pull the engine out of the car. Took them from March to August to get the engine back into the car and running to any degree. Shipped the car back twice to fix the new engine for the same issues and It is still not fixed. I’m stuck in Albuquerque with surging in low idle speed to the point it pulls through the brakes, stutters at highway speeds like there is a clogged fuel injector and no one can figure out how to fix it. It took them two years to rebuild a motor that still doesn’t work. I have a email trail that is two years long dealing with the promises and excuses. I wouldn’t recommend them for anything at this point. I have spent close to $20,000 to rebuild the engine that doesn’t work and wasted two years with the vehicle at their shop almost the entire time. Not sure what the issues are but it is not the same shop that put in the Stage I.

Do you have a handheld tuning device of any kind? If so we can. Any custom tunes though I have to advise are not California compliant. Honestly we only really deal with SCT stuff but it might be best to call and talk to Ricardo or reach out to us via Instagram.
Hi as a shop helper at GTR we don’t do much for V6 platform but we will be happy to do what we can for you. Please feel free to contact us at the shop anytime.
Nope unless you have a customized lower manifold/cooler to fit that

Hello, we mainly work on Ford Mustangs. Sorry about that!
Hi! We mainly do the Ford Mustangs, so I'm not too sure on those cars... sorry about that! You might have to look online for something like that. Thanks, GTR High Performance
Yes it is but preferably better just to come in
Mainly specialize in Ford Mustangs.
Mainly specialize in Ford, mostly Mustangs.
It's probably a better idea to contact them directly then on here. They do more than just Mustangs or V8's for that matter. I'm sure they can help you find what you are looking for.
Call Ricardo
No. Rear wheel drive vehicles only.
