I bought a s2 intake manifold for my GSR but have not installed it. I will be installing CTR cams, 4-2-1 header with 2.5 collector and Intake. The car will be tuned with hondata or uberdata. This is my daily driver and i want to have usable power and keep my midrange. I am looking for first hand experience of anyone using CTR cams with the stock intake manifold and your opinions.

BTW it may be for sale for 180.00 plus shipping.

 

I'm using a pair of CTR cams in my JDM GSR with a bone stock intake manifold (for now) and they really woke up the motor. You could feel a night and day difference in mid to high end power. Myself I'm gonna try a ported gsr manifold with butterflys removed and a 70mm throttle body. The S2 intake is still a great piece though heard alot of good things about it on GSR's, needs some tuning though. My advice, start putting on your parts

 

I have CTRintake/ITR Exhaust combo on my LS/VTEC using GSR head and stock IM... Numbers are in the sig, tuned w/ 440's...
