3.8 cayman
Although most of the is forum is dedicated to aircooled motors, here is a change of pace!
3.8 conversion on a 987.1 Cayman S. LN engineering sleeves, JE pistons, Schrick cams, IPD intake plenum, ECU tune and complete exhaust including catless headers... Here is where it is at so far!    And the reason it came apart in the first place...  Cheers

The scoring of the bores and pistons is becoming more and more common on M96/97 engines. The current theory is that the piston expands quicker than the block during a cold start and their is not enough clearance to accommodate this...

You will see increased oil consumption and begin to hear a ticking sound similar to a failing lifter. The ticking and oil consumption will get worse as the scoring continues to develop.

How did this build turn out? I'm specing out a very similar 3.8 conversion and was considering Schrick cams. Finding feedback or performance results on these cams by anyone has proven hard to come by. What HP/TQ did you get, swap in all new lifters, anything else?
Any feedback greatly appreciated. |
