WHEN REBUILDING AN M96 OR M97 ENGINE, THERE ARE MANY CONSIDERATIONS WHEN EVALUATING YOUR OPTIONS.
Re-ringing your M96 or M97 engine isn’t even an option for most rebuilds, however most engine builders re-ring engines after only doing a visual inspection of cylinder bores rather than measuring the cylinders for ovality and taper. It is a guarantee if the engine has not been sleeved, the bores are out of spec on even a “fresh” rebuild.
Through our exclusive Nickies sleeving process, we have overcome the d-chunk, slipped-sleeve, scoring, as well as taper and ovality issues associated with Porsche 986/996 and later 987/997 models.
The price shown is for all six cylinders on the block process. Service applies to M97.21 and M97.22 engines.
Note: Although it is possible to increase your displacement to 4.0 liters by using a 3.6/3.8 82mm crankshaft, the extra cost for reworking the crankcase and 82mm crankshaft does not make this option cost-effective. We would recommend saving the money and investing in upgraded internals and cylinder head porting to build a stronger and more powerful engine for your 987.
