No better place to go! I called at least 20 places to find a turbo for my Cummins in a hurry, everyone said no they couldn’t get me one by the weekend. Ja performance worked hours to get me the turbo I need in the time frame I had. He got it to my door in less then 24 hours. Great guy very easy to deal with!

One of the nicest guys in the business. Returns your calls, doesnt let you waste your money on parts you dont need. Builds one incredible motor.Been through a bad experience with an engine builder in NJ.Took the unit to James to have it refreshed only to find out the NJ Builder lied about some of the parts he was suppose to install. Of course he showed us the parts that were suppose to be put it just never made it.

Great guys and they built some awesome engines

He is the best.

The Best!!! James is so honest and balls on with his expertise with every aspect of engine building!! Many Race/Show Cars proudly display JA Performance on their motors. James is a dying breed. Go for it!!!

Built me the badest pumpgas 555 in the country ! He’s Honest tells you everything up front no surprises and does what he says he’s going to do, and these days that’s more then any of these wannabes out there and a good person besides a great engine builder .
