Flywheel And Clutch

[Nytrosfinder]

Alright here is the deal, I posted this in a few places but to cover the whole thing here it goes.

Spring break March 12-21

Mission: Bring Pathfinder home and get her running by the 20th

 

While I have the motor out, I might do an engine swap or a rebuild... depends on what I can find between now and then

 

Considering the motor is shared with the 300zx, is there possibly a lightweight flywheel or a performance clutch I could put on it while I have the motor out???

 

If not, should I replace the clutch while I have that area disassembled?

 

Any thing would be helpful...

the 300zx fidanza and stillen flywheels fit the pathfinder 3.0 and 3.3. Many belive the pathfinder/pickup OEM clutch to be be superior to any aftermarket "upgrade".

a flywheel will let you rev quicker and may save a MPG or 2

 

BUT less rotating mass on the flywheel means less torque derived from inertia. What that means is that if you are charging @ an obstacle on the trail it will take less restance to slow your driving down. get stuck in the mud cause you couldn't keep your tires spinning fast enough?

I'll have to pretty much agree that there is little point in changing anything. If you wheel, you probably want the heavier flywheel and the stock clutch is quite adequate for anything other than racing.

I'm not knocking the flywheel, It is a proven MPG gain and a lighter balance which is good for engine life (thats reason enough for me) I'm just makin sure you know what else to expect(as in pretty much no other benefit to a pathfinder)

 

look on N4W for info about clutches I think you'll find that as much as they "roast" their clutches on the trail the OEM ones have always kept grabbing longer than aftermarket. I my first OE clutch wasn't even in need of replacement @ 190k but it was done anyway because it was part of whole the trany swap package.

Makes sense to me... I will stick with stock stuff...
