Difference? R32 -> R33 Gtr Crank

[johnbarry88]

Hey guys like the title says im trying to find out the differnce between the 32 and 33 gtr crank any help will be appreciated.

I was told by the guy who built my engine that the area that the oil pump attaches to the crank is superior......It was only last Friday I was told by someone else I trust a little less, that there is no difference, and that a 33 crank would need a collar to ensure the oil pump had a good grip on the crank.

I too would like to hear the answer to this one.

Whoever you trust - dont trust them cause they are horridly wrong.

R33 does NOT need a collar.

As for pics/difference... plenty of threads. Its just the oil pump drive. Thats it.

Ive got pics here somewhere.

Notice the larger surface area of the flattened oil pump drive on the snout of the crank on the R33 item. The R32 is significantly smaller. You can see why they crack oil pump gears.

That third pic sucks, but it appears to be an R33 crank.

You just saved a grand on a new crank! Now you can go spend it on a million other things needed for what you are doing. Ive been there!

hey shaun thanks for the info. I actually bought the engine as a running standard r32 engine got it home and the insides were stuffed but thankfully it had those magic numbers on the side 24U and now it has a 33 crank thank you god!!!
