i dont know if this is the right place to post this but i am..lol im looking to build up my b18b1 im doing an ls vtec and i am boosting the compression ratio to around 11.7-12.1 and want to put forged rods in the car and i was wondering if b18c rods will work i no they are a little longer and i just wanted to make sure before i bought them

thanks

 

If you put GSR rods into your LS engine it wouldn't be an LSVTEC. GSR rods have a smaller stroke for top end revs. LS have a longer stroke for more torque.

 

stroke is determined by the crank. not rod length

 

im pretty sure if you use gsr rods, you need to use the gsr crank too.

 

stroke on the LS crank is longer than GSR. I don't think it'll work.

 

thanks

 

They are correct you must use the rods/crank together. The length is different on those rods. GSR is 5.433 rods LS/B20 5.394 Use the GSR rods and LS crank and be ready to hear those pistons crash the head!!

 

don't forget that the gsr big end is narrower then ls aswell

 

Ok I have an ls vtec swap that bore over n some things done to it.. One question, are the stock b1 internals forged? Because I know my crank is stock, but I have forged rods, I don't think there were any markings on them, def. not gsr rods.. R the stock b1 rods forged or no?
