Engine Internals & Assemblies
While it’s easy to focus on the big components of your car’s engine, there are a lot of small parts that help make everything go. Rod bearings, drain plugs and crank straps may not seem like much in comparison to the heads, valves or intakes. But it’s these parts that keep everything connected, sealed and working together so you can go flying down the back stretch or nail a four-wheel drift. The gearheads at Modern Automotive Performance know how important they are, and our inventory of engine internals and assemblies has everything you need for routine maintenance or a complete performance rebuild.
No matter what you drive, you can find parts to get the most out of your motor. As a leading authority in DSM performance, we have a great selection for Mitsubishi Evo engines, including Evo X rotating assemblies and rods, head stud kits, main bearings and torque plates. For KA24DE engine–powered cars such as the Nissan 240SX, our KA24DE performance parts include Wiseco KA24DE forged pistons and Eagle connecting rods. Toyota drivers can pick up a Scion FRS Forged Internals Kit packed with quality parts. Owners of GM, Chrysler, Honda, Subaru and many other car makes will also have plenty to choose from.
Crankshafts, cam gears, oil pump chains, head gaskets and dipsticks are just some of the thousands of engine internals you’ll find at MAP. We also offer internal rebuild kits and stroker kits containing parts used on our in-house race cars. With OEM replacement parts, industry-leading brands and our own in-house components, you’ll have options for any level of performance. In addition to our fitment tool, you can also sort by bore size and compression ratio to find the parts that will fit your engine. Our experts have spent decades working on cars, and are available by phone or email to assist you with questions. Order today and get a competitive price on quality parts, with free same-day shipping on qualifying items.
