Gtr Crank To Gts-t Block

[skylinekid]

hey fellow skyline owners im currently building my r33 gts-t engine up from scratch and have been told that the gtr crank will drop inot the gtst block. my only concern is the gtst crank has a 71.7mm stroke and the gtr crank has a 73.7mm stroke but the lengths and height for gtst to gtr rods and pistons are axactly the same. im wondering whether or not the deck heights of the blocks are different or the 26 head gives more squish space but im just not sure. i wanna put a gtr crank in the gtst block h beam eagle rods and je forged pistons but im just very unsure if i would have to have custom rods made to suite gtr crank. anyhelp would be much appreciated thnx....

Deck height is the same.

Only difference is the piston compression height.

If you use a rb26 crank, use rb26 pistons.

I built a combo like this a coupla weeks ago, no probs.

the RB26 piston has more of a dish in it?
