so in what little free time i have, im actually attempting to get my car running again, i swapped out my cam for one with a cam key but just need the tq spec for the cam caps. RB25DET s1

also a few people may suspect my wiring to my z32 maf might be wrong. something about the wiring because i have a power fc? that it was able to start up once only? im not exactly sure, but I sure would like to double check to make sure its correct. can someone guide me, link me or something so that i can make sure all my wiring is correct for the maf?

help me out, thanks

Not 100% on the rb25, but the SR is like 7 ft-lbs. I'm sure it wouldn't be far off from that.

Cam caps torque - 0.92 to 1.2 kg-m, or 79.8 in/lbs to 104.2 in/lbs.

When tightening cam caps, try to use only a 1/4" torque wrench. The larger 3/8" torque wrenches are not nearly as accurate at those low torque levels. Hell, some of them don't even go below 10 ft/lbs.

And for future reference, those specs cam directly from the Skyline FSMs, available for free at http://www.nicoclub.com/FSM/rb/
