okay here it is my buddy bought a set of itr rods and ctr pistons now the question is will this fit in an ls block with an ls crank?

I have been told no and yes but not sure any help will be apprieciated thanks

 

help

 

well I would but he already spent a ---- load of money on it with out researching anything and I really wanna know if it will ---- everything up the first time he cranks it over

 

No it wont. The rods will be too long. Ls rods are shorter because the crank has more throw. You can swap type r and gsr ---- but the ls will only swap with the b20 rods.

 

what if he runs a gsr or type R crank then?

 

Then it will work fine. You can find a crank easily on Honda Tech for just over $100 shipped. You might just want to keep the ls crank and buy ls rods instead though. With the ls crank youll have 1834cc of displacement and with the gsr or the type r you will only have 1797cc(i think those are the numbers). It doesnt sound like much difference but there is a decent ammount more torque with the ls crank. If your going to be revving really high just make sure to have the ls crank balanced.

 

the type R piston will fit a LS block.
i know i did it.
and for rods all b series rods are interchangeable. its u got to mach the baring size up
i have put GSR rods on a LS crank
what u have to watch for is the clearance the part where the piston meets the head. the longer the rod the more compression.
rod lengh i am not to shour about i know SI rods are the smallest in lengh.

 

all b series rod arent interchangable. LS and B16a rods have a fatter piston end then GSR and TYPE R.
the crank ends are the same though. you can machine the LS or B16 rods to accomodate the GSR and Type R pistons.

simple rule, crank and rods need to be from the same engine

 

thanks guys that what I needed to know I wanted to make sure they would hit the head or bend valve or over all just destroy every thing
