I want to put cams in my GSR coupe. Which would be best and most efficient.

 

the ones you can afford that make the most power.

my vague response to your equally vague post. you didnt mention any of your mods, power goals, intentions for the engine, budget, yadda yadda yadda.

 

i'm guessing you have the basic i/h/e...with a b-series swap...i'd say get some ITR/CTR cams or you can go a little more and go with skunk2 stage 2's...but with these you'll have to upgrade your retainers and vavles i believe...
