Ok, time to do some thinking, I'm going to be rebuilding my GSR due to major rod bearing failure. So here are my options.........

GSR block, LS crank, LS rods, .25 over ITR pistons.

Total displacement = 1857cc ( I think )

Now, what's the force exerted at the crank on the LS rods. Would it be better to just use the LS rods, or go for some Eagle units.

I believe maximum revs should be just under 10k.

GSR crank = 87.2mm
LS crank = 89mm

Difference in rotation .9mm

Lastly, I can also go with GSR rods, and CTR .25 over pistons. Would the difference of -.9mm drop the c/r too low? Or is it just a waste of $$ to do this?

Thanks.

 

still can't do it unless you get ls rods and they suck.

 

also you want a moor that revs you wont get that out of the 1.53 r,s of the ls stick with the 1.58 of the gsr. or just bore and sleeve a b16a.

 

Get the Eagle rods, the LS rods are just not going to take it...
As for RPMs, get it balanced, should be just fine. I have not really beat on mine yet (not tuned yet), but it is a difference in torque down low...

Yea, that's what I was thinking too. The LS rods are ok for low revs, but once you get past 8k, they start to go to hink I'm going to get the Eagle rods.

 

you cant use factory pistons with aftermarket rods.
if you do you will have to have the piston modified.

 

To make the piston a floating wristpin?
