I've got the same rig. mine has 375+K

I just had the topend done, but that was because the last shop really [email]F@cked[/email] up the last time. My new mech said they used the wrong headgasket...the thinks it was for a Camry.

Right now it is running real strong, but it needs CV boot, muffler, tie-rod warranty thingy and a PS box (the PS has a slight leak. I've had a spare for the last 2yrs, but haven't wanted to deal with the pitman arm.

I think the only major things I haven't repaired/replaced is the transmission, xfter case, cat, and ball-joints.

Semper Fi,
Alfred
