KIT Motorsport Piston 5inline 81.5/ 82/ 82.5/ 83mm + Motorsport H-Beam Connecting Rod 144 / 22mm 8.5:1 compression for stock block + 92.8mm crankshaft

Our solution for power in the stock engine block, using the 92.8 mm motorsport crankshaft. This increases displacement to approximately 2.5 liters while maintaining high revving (revs up to 8,500 rpm are possible).

With this KIT, we close the gap to the 2.5L conversion with 22 mm piston pins. Above a certain power and rpm, the too-thin 20 mm piston pin tends to bend or wear out the piston bosses, which then become oval.

That's why we now offer this solution with the already proven performance piston (22mm piston pin), for which there was previously no suitable H-beam connecting rod. We had the connecting rods specially manufactured for this purpose. Naturally, they use the well-known ARP2000 connecting rod bolts.

The KIT consists of:

Motorsport pistons 5inline 81.5 mm to 83.0 mm (please select the correct piston size) + Motorsport H-beam connecting rod 144 mm / 22. Compression ratio: 8.5:1. Over 1000 hp have already been achieved with this KIT. Arguably the best connecting rod-piston combination currently on the market.
