Main bearings are a major repair (engine rebuild stuff).
I would be getting some quotes for a rebuild and also for second hand engines.
Not going to be cheap either way.

1988 300zx non turbo 2+2 need to change fuel filter don't know where to locate it on vehicle. warning.. female operator :-)

It is under the hood, on the passenger side, on the side of the strut tower, mounted in fuel line hose. If you are having a hard time finding it trace your gas line back from your injection rail/throttle body and you will run right into it, can't miss it.

a new car? I"M KIDDING!!! Haha! I'm sorry... I am a certified Nissan Scope Technician with over 10 years in a Nissan dealership.

These cars were kinda built "doggy" due to emissions regulations out at the time and it's a heavy car for what it is...

The first thing I would do is put a bigger turbo with a front mount intercooler and larger fuel injectors on this vehicle for more performance. The block is pretty much bullet proof to upwards of 350 horses...

I've built one of these cars that runs 10.50's in the quarter mile at 120+/- MPH...
