I just picked up a set of gsr cams for my turbo motor.. It's a gsr block, @1bar, built but not sleeved. stock b16a head. I heard I would get a noticable difference once installed. I will be using my stock valvetrane, so I will keep the rev limit to 8000rpm, but i never go that high anyways so I should be safe..
They only cost me $100 from a good friend so why not.

Whats the spec's on these?, I sthere a way to tell the difference from a b16a cam and the gsr? They have PR3 on the cam gear.. ? should'nt it be P72??

 

read through this...i didnt take the chance to look through it but if theres no info than i'll do some research for ya
