If you have a B16, tell me if youve noticed a diff when switching to GSR cams. I know they have the same lift (GSR is one degree less on the exhuast, i think) but the GSR cams have alot more duration. Would this be a worthwhile swap? Opinions welcome.

 

c'mon...

 

Oh yeah, you could rev it higher i believe. In theory: Less lift, More Duration= Good high rpm / More Lift, Less duration= good low rpm

 

I heard they are the best priced cam for turbo and I got a set with my GSR engine, I threw them in but didn't notice a significant difference. After going turbo nothing feels like it makes more power except more boost.

 

Yea, well for us all-motor folk, we'll take every ounce of lift and duration we can afford.

 

i just did a serch on this and this is the only post that came up. I have a B16 in my CR-X and have a complete GSR head sitting here. I've heard of people swapping out the Injectors and the Cams. IS IT WORTH THE TIME? (My set-up is All Motor.)

 

Injectors are the exact same.

 

thanx Beta13, what about the power diffrence in swaping out the cams fellas? ^

 

Ok, injectors are the same from LS to ITR, 240cc saturated. Dont bother with injector swapping. As per Crower.com, the cams are significantly different. This is kind of an old post, im going with the full GSR head with dual stage mani on my B16. That should cure alittle of the torque issues.

 

your gonna put a GSR head on your B16(block)? help me out here,confused.

 

Yea, I have a rebuilt B16 block that I got as my B-day present (21....woot) and Im getting a GSR head on a trade, so what? I didnt ask if you got the reasoning behind it. But, since we are on the subject, Im hoping the dual stage manifold will help in moving the torque curve lower thanks to the longer manifold runners before 5750RPM, and the smaller chambers of a GSR head will yeild a 10.44:1 CR and it has bigger cams to boot. Its not a bad setup if you can get past the "Why not just use the GSR block" way of thinking.

Plus, Im not complaining about the 1.74:1 rod ratio, either.

 

the reason i asked is because i have a built B16 block(bored .25 over w/CTR pistons,lighten FW) sitting in my garage (next to my GSR head)I thought about slapping them together but never really did any reserch on this,other than people telling me i would have to use a difrent IM,sutch as a SK2 IM.Has anyone ever tried this?

 

If you are using CTR pistons, then your CR will be in the high tens, low elevens (im not going to do the math right now) with the GSR head. YOu can use the GSR manifold to help torque as I am doing but youll need a P72 ECU to control the dual runners. If you were to use a Skunk2 manifold, then you can use your old ECU.

Just plugged in all the values, your CR will be 11.07:1

Hmmmm.

 

Back to Origanl Q: Who noticed a differance between B16 and GSR cam? anyone else?

 

Hehe, my original question and now im the one answering questions. Yea, lets keep this thread up untill someone who has a dyno sheet sees it. Or at least untill bedtime. Either one.

 

between 2nd gen b16 and gsr cams there isnt much of a difference in power, it would be very small if any.
now, if you have 1st gen b16 cams, it makes good gains.
in my car i dropped .2 in the quarter by swapping 1st gen cams with b16's
If they're free or come with the head, i'll say swap them
