This is a brand new set of Wiseco Pistons and Manley H-Beam Rods for 6 Bolt Mitsubishi 4g63t 2.0L Turbo engines found in early model Mitsubishi Eclipses, and several other platforms. Please verify you have a 6 bolt crank (and not a later model 7 bolt crank) before purchasing these parts.
We like to use the Wiseco/Manley H Beam combo in platforms that will be making up to 700hp. If you are planning on making over 700hp, ask us about our High Output Combinations today! Wiseco and Manley make several different pistons and rods and we try to keep many of the most popular part numbers in stock. Just select which part number best fits your application from the list below, and include that part number in the paypal notes section of your payment.
All pistons come balanced within one gram, include pin lock grooves and wrist pins at no additional charge.
