996 Deep sump conversion

Just by boring and stroking it the compression will be sorted or too high depending on what pistons are used. With regard to the heads it is possible to achive near 150hp with just sps cams , stock 50mm exhausts at 996cc as long as the ports are changed to the correct shape (not just a big valve port clean up)

There are too many options with that motor .

I'm using 996R pistions but with the bigger bore when I've reshaped the chambers to match the bore size I hope it will be about right. Bring on the horses!!

So your using standard 996R 100mm bore flat top testastretta pistons ? Or do you mean the pistol R 1999 100mm piston for a bored +2mm 996 desmoquattro.

I know somone who was selling some with cylinders and a 998 crank
