GT-R turbos on the VQ37

You can change the bearings without entirely rebuilding the engine or even removing the heads. That is, if you felt it was worth all the work. If you planned to build it in a year anyway, I wouldnt bother. But if you wanted to get several years from the stock engine it could be worth it.

I've changed bearings before without pulling the motor. You might be able to do the same thing. Depends on how willing you are.

In the Z you need to remove the engine to remove the upper oil pan. This would get you access to the rod bearing. If you needed to do the main bearings too the bedplate will have to come off and thats essentially a full tear down except you can leave the heads on.

I suppose you could also drop the crossmember to get the upper pan off but that is a nightmare. I did that with my DE once to change the rear seal housing and it was torture being under there with the engine dripping oil on me the entire time.

I've lifted a couple of V8's up with hoist. Dropped the pan to change the bearings. Yeah, forgot how the bottom of the Z motor is. Not enough room, even with the motor lifted.
