late 944 u.s. spec?

[uvachief]

I've read that the u.s. spec 944 na has horsepower of 147 to 151. Anyone know the real answer? Also, how many foot pounds of torque? 86-88 models.

Factory figures:
86-87 US 143hp 186tq
86-87 ROW 163bhp 205tq
88 All 160hp 210tq

Okay...where can I get a 86-87 ROW dme/ecu?

86-87 ROW engines had a higher compression ratio. Just replacing the DME is not going to gain you anything. Are you also replacing the pistons?

I rebuilt the top end in May of 2011 but I did not modify the pistons so I guess that idea is out the door. Thanks for the note.

I really do wonder if I have euro compression.. since my compression values are so high..

Just take the head off and find out. Here's what I found in mine..... US spec.

But seriously.... maybe a boroscope through the spark plug hole.

Either way, very happy with 190 psi compression haha

Yep, you need those Euro pistons (on the right), a DME and cat delete to get to Euro spec.



Here are my 10.6cr Chinamen before they were coated and installed:
