LS crank?

[Slava]

I know some already did this but I don't know who.


Has anyone put a LS crank into a GSR block?

From what I've wread on honda-tech it gives you more torque. But what are the cons?


Pros:
lighter crank
more torque


Cons?
I think some said something about lower revs?


This is on a boosted GSR motor with CTR cams.

I'm running an LS crank in my GSR block and I love it. A little longer stroke provides you with more torque. 87.2mm vs 89mm.

I ran to 9600rpms last year without a problem, and I plan to run to around 10000rpms next season.

I didn't think its lighter, if anything I'd guess its heavier because it has a longer stroke and a wider rod journal.

deck heigth is the same for a gsr and an ls.. you have to use ls rods though
I was going to go this way... Servion has a setup like this..
rev's are more based on the head assembly..

and he beats me to it

hahah :)

Yeah, springs, retainers, rodbolts are the first weak links for revs.
