GTR Crank Questions...

[RB_26]

Thinking of building a new engine.. if I get the time..

What are the differences between a 32, 33 & 34 GTR Crank? ie stronger etc?

Can they be used on any RB26 with no additional mods?

How much are they new from a dealer... ?

What would you expect one to go for used?

Thanks

R33 and R34 cranks have the longer collar to run the oil pump as the R32 cranks had a thin one that can cause the pump to fail. You can add the collar to them.

I don't think there is any strength differences, if there are it's minor.

They can all be used in any RB26.

New from Nissan here, the last one was around $2500-$3000 ( I don't recallexactly how much we paid now ..) They are R34 GTR cranks, ex Japan. Got it in 1 week.

Second hand cranks go from $100-$1500. Quite often when bearings run the crank goes beyond tolerances.. and is no good unless you use different bearings, which is a bad idea.

A good second hand one with no wear would be worth over $1000.

The main thing to look for is worn thrusts and cracks.

Thanks, Is it fair to say that a used crank evenwith new larger sized bearings (after the crank is ground) will never be the same? Sorry to be such a newbie here but is it possible the re-ground crank & new bearings is more likely to fail as opposed to a new crank with new bearings? or are we just talking lady luck here?! :Paranoid:

Say you go for the r34 crank, what con-rod bearings would you recomend? (say 550whp) also do the rod bolts? Again type to go for?

No cash for steel.... so have to make do with stock'ish setup.

What will the stock crank hold? if held down, good oil supply?

Sorry.. question city here!

Fark me Troy, is there anything you can't do? Honestly, that's bloody amazing. So much for "jack of all trade, master of none"

Wow, any of the complete car as yet?

Sure tempting on the crank - is that from a dealer? Any links?
