im asking this for a friend of mine he currently has ctr cams in his motor and he got a set of gsr cams and he was asking me if I knew what was better. ctr intake and gsr exhaust or gsr intake and ctr exhaust. (I didnt know the answer so thats why im posting)

this is his setup

Use both CTR cams.

 

with that kind of set up I would definitely get a 3" downpipe

 

without a 3" dp run both gsr cams. with 3" dp definatly both type r cams

 

im going to change the dp to 3" and retune and I need to figure out which cams to use

 

Use the ctr cams, much better then gsr.

 

type r cams best OEM cam for boost

 

meh both are fine, you can make over 600whp with both

 

wow, whats up with people trying to missmatch cams, its just retarted, this was done back in the day only because cams where so expensive and cheap *** people were being ghetto, THERE IS NO REASON TO MISSMATCH CAMS, ITS 2009 FOR GOD SAKE!

but to answer your lame easily searchable question use CTR both.

 

whats wrong with ctr intake, gsr exhaust theres not a whole lot of difference on the exhaust side is there? its been awaile since ive looked at the profile specs

 

Dur @ .050
GSR 230°/216°
CTR 233°/224°

 

i would like a gsr cam then, shorter overlap with minimal valve lift changes

 

its your car, do as you like...

 

i made 800hp with ctr cams

 

gsr exhaust sorry, ctr intake

 

once again, its your car, do as you wish... both cams are proven, one is proven to make more than the other but if you think you know some better way go for it...
