Engine Rebuild

[19pathy95]

I'm getting the engine rebuilt on my 95 pathy and I was wondering about any tips or recommendations to make it more durable or stronger?

replace the studs for the exhaust with 300z ones. Search the forums for the part numbers.

Either '84-'89 300ZX turbo studs or '96+ VG33 studs. Both are 10mm.

 

Without going wild, there's not much to do with the engines to make them any stronger that won't cost an arm and a leg. The cranks are stout, rods forged, main girdle set up, the blocks are a green casting, and the clearances are nice and tight. Now that being said, a major problem with the VG30s is the cross drilled oiling system where the engine starves of oil at 6,500+ RPM. Good thing the stock limiter is set below that. One thing you can do/have done is open up the oil pump and make sure its still 100% and have the passages ported out and smoothed. This gives you much better flow. When its being rebuilt the machines MUST grade the bearings to each crank journal.

 

Mainly, use a good oil and filter. Cheap garbage doesn't save you any money in the long run. An oil filter relocation kit is a worthwhile investment for added oil capacity, more filtering media, and you don't spill oil all over the starter when you change it.

 

DO NOT USE FEL-PRO HEAD GASKETS!!!!!!!!!!!!
