Hey h-t, im looking to pick up a jrsc tommorow... and I was wondering if the gsr one fits LS because in the ad it says fits GSR AND LS but on the website it strictly says B18C1 AND B18C5...

 

It will fit on an LS block only if it has a GSR head on it. The JRSC uses a custom intake manifold to attach the blower, and the LS & GSR have different intake manifold bolt patterns.



Cliffs: No. The ad is misleading you.

 

ok thanks,worst case scenario i just have to sell it back to someone with a gsr then ...

also do i NEED to get it tuned, I heard alot of people say u dont need 2 tune in but im really skepitcal on that ! cuz it comes with injectors aswell so more fuel I dont want to lean out the motor

 

doesnt hurt to tune, my personal opinion is no tune equals ticking time bomb...

 

hondata s300 would be a good investment. has basemaps for JRSC systems on each b series motor

 

Cool thanks guys now heres the BIG question... Is it woth it to JRSC my LS ... im not looknig to be the fastest car im just looking to have some power to have fun with ... alot of people say its not worth it but some people say its worth it

 

Well you have the right block to do it with for it already has LCP so you should be ok with 7-10lbs, but i would def get a tune on it.... and for fun and power ya i think it is, especailly when people pull up thinkin im going to hate on this LS and get smoked instead!! haha
