cruzer Posted July 17, 2020 Share Posted July 17, 2020 Hi Guru's I'm trying to figure out what the difference is between the 280zx L28 vs Patrol L28. From random bits of information I can gather: 280zx F54 block N42 head P90 head Patrol F54 block P90/P90a head with Hydrolic lifters Cam profile for low end torque Deeper sump Anything else?

pauly_adams Posted October 28, 2021 Share Posted October 28, 2021 the harmonic balancers are different between the 2 the patrol sump dips more towards the middle but still works in a S30/S130 block wise it can be N42 or F54 and ive never come across one with a P90 only ever seen N42 heads the oil tree can be different Intake manifold is a single 2 barrel Cam profile is different between the patrol and S30 the flywheel is larger on a patrol other than that, there pretty much the same internally Quote Link to comment Share on other sites More sharing options...
