Joey/datsun

Well I have a 95 c280 ,the engine harness is **** and compression in #1 is (45 psi). It's been sitting in the garage for awhile and figured why not try to rebuilt it. Curious if anyone has a write up or something that explains how to pull the motor out and what are the motor internal specs? I know I've seen that these motor are 10.1.0 compression and has anyone ever bothered to lower the compression? Probably going to get bashed/hate by some of you guys about why waste your time on this car.
