Over the years, we here at MAPerformance have built hundreds, if not thousands of Evo X 4B11T engines and we like to think we know a little something about the parts that go inside them. Give us a call at 1-888-MAPERFORMANCE if you need some advice on which pistons and connecting rods will hold the power you want to make and our experts will give you all the information you need to make an informed decision. We also offer Staged Cylinder Head Services that can turn your stock head into a thing of beauty that will handle the abuse a track car takes. Don't forget the engine oil, the lifeblood of your powerplant. Maybe you're more of a show-er than a go-er... we also have dress-up parts to make your engine bay to talk of the show.
