GTR Cranks 32 vs 33

[BigMicky]

Now I know this topic has been done and I have done my research but am left a bit confused....

I know the 33 GTR crank has something different with the oil pump drive that gives greater reliablity.

Can I put the 33 GTR crank straight into my 32 GTR engine?

my crank has spun a rod bearing on number 5 and needs to be replaced so I though I might as well upgrage at the same time.

the crank can probably be repaired, but I think its worth the cash to just get a new (or good secondhand) one.

Your thoughts??

mate i've already been through your path.

in my garage i have 2 RB26 cranks sitting

1.R32 GTR RB26 with a crank in the middle

2.R33 GTR Vspec RB26 with a crack found after crack test. (second hand)

they are the same material but the pump driver is wider so there is less chance off oilstartvation.

i currently have a R33 GTR N1 in my RB26 wiating to go in.

the 33 crank will be a straight in straight out for the 32 block.

invest in a new crank well worth the money..

but if u cant. get the second hand 1 crack tested and buy it.

u can not see any internal cranks

Hey Danny can you get a pic of the 2 crank collars? there are a lot of questions about this....

Yes I'd like to know too , I gather the later cranks are wider across the flats that drive the oil pump . Or is there a difference in diameter as well ?

Cheers A .

If your crank is still ok ( no cracks ) besides no 5 pin , you can have it rebuilt .

They dip it in hard chrome to built up the pin and then have it regound .

Its not cheap though as its time consuming , around 100-150 to do that one pin then another 150 to regrind the lot , big end and main pins .

Just another option that we have used many times before on cranks and cams .
