Haven't posted in this thread in what seems like forever.

Lost a motor on the banking of Auto Club Speedway and started planning a new ultimate Boxster engine... It has taken quite some time to get everything together but things are starting to move again.

Bought a 3.8L X51 crate motor. Had a scarred cylinder 3.8L engine sleeved for an increase to 4.0L. Going to use the 4.0L case, worked X-51 heads, X-51 intake, custom 13.4:1 JE Pistons, Carillo rods, GT3 rod bearings, and our new dry sump system. Sold my Pectel ECU and will be making the switch over to the Motec M1 series. There will be a bit or wiring involved in that swap also.

I've finally got the custom pistons in hand from JE. They spent some time scanning the cylinder heads and we clayed the motor to get the valve pockets filled up as much as possible. Their milling process also took out a lot of weight, so we are down to 386 grams.





The dry sump system still has some work left, but it should be pretty trick. More photos when we are further along with assembly. Might be the first one of it's kind on an M97 engine? We may actually end up over 400rwhp and live for awhile...

Also had time to get the custom roof mold done. Selling off the prototype and making some production models now. Hopefully they will offset some of the cost in getting that thing built. The new version is a lot lighter! It is a mix carbon, fiberglass, and foam stiffener.
