Rb Block Differences

[andy kain]

Might be a strange one but is there any difference between the R33 GTST engine block and the R34 GTT one? Just talking purely block not head or anything.

Reason, I am building a second engine for my Rb25DET (neo) and I have the chance of an GTST block at a reasonable price and although I have good mechanical knowledge, I have no idea if there are any differences between the 2 that I should be worried about.

The main differences are in the head mate.

The blocks i believe are the same, if not very similar.

I have another head and associated bits and bobs, it was the block I wasnt sure about. Many thanks for your reply though, I will get one on order and crack on with my build
