Introducing our brand new 87mm stroker crankshaft for the M10 engine! This is basically the 2.5L S14 crankshaft but with the nose machined for an M10 motor. These cranks come as knife-edged and ready to drop in. These are new crankshafts, NOT reconditioned S14 ones, so the bearing sizes are always standard. Given the bore of the M10 motors is between 89mm-92mm you should expect displacement around 2.3L!!!
Crankshaft made from billet 4340 steel and balanced to factory spec.
Note that this crankshaft may require some small modification to the underside of the block (grinding) for clearance of the counterweights or especially the connecting rods due to the increased stroke.
Custom pistons take 4-6 weeks to produce. See our other listing here for more information on custom pistons.
