Instead of using a LS bottom end to achieve the longer stroke, could a LS crank and rods be swapped into a b18c bottom end?

This way, no vtec mods have to be done, and you get the extra stroke.
just a though.

 

works fine know a couple of people who have done it

 

I would like to hear more imput on this topic. Bump.

i thaught (don't know if i am right) that the gsr block is not high enough to accomodate the longer rods and crank
i have heard of ls block gsr crank and some unkown rod length don't know though i might be wrong

 

It is my understanding that the LS and gsr share the same block height, and same bore. however, I think the gsr block needs to have the bottoms of the cylinders machined to have clearance for the LS rods. I believe the cranks are the same size though.

 

As long as you use LS length rods with the longer LS crank, you'll be fine. That plus the bottom end width of GSR rods are narrower than LS rods. The journals on the crank are narrower on the GSR crank.

How difficult is it to machine the journals to allow clearance for the ls rods? Is this something i can do? or should i take it to a shop?

the oil squirters get into the way. simply have them moved back a lil bit (away from the rotating mass) and ya good to go. everything else is the same. height and bore

Is it possible tp just "move em back a bit" ? are they not attched to the block? also... what about rod clearance?

 

BUMp

 

i am in the process of building this set up.
it will consist of:
gsr block
balanced ls crank and rods with arp rod bolts
arp head studs
ctr pistons
gsr head

as soon as i know you will know
am waiting on the parts as we speak
i will move the squirters instead of taking them out if i can that is
