Would the V-AFC and cam gears make any sense to get with my current mods (I/H/E)? Would I be able to pull a little bit more power with them? Or would it be a waste of time without going with something like ITR cams? Better yet would just cam gears be ok since I've heard that the V-AFC is kinda useless without upgraded cams?

 

I think you nailed it, just wait and get all three, then dyno tune to get the most out of the cams/gears.

 

ive recently heard you really only need the itr intake cam, is there truth to this?

 

and also if you only use the intake cam do you raise your rev limiter and change valve springs?

 

get BOTh cams. They work together. I have stock springs

 

Using Just the intake cam would suffice for you.... I would say that if you plan on revving past 8300 or so, which the ITR cam likes... then swap the valvesprings/retainers... I would much rather pay for the valvesprings/retainers and not worry about floating a valve...

Cam gears are a must for tuning. Obviously, tune them on the dyno.

Also... for such an agressive cam... look into the Skunk2 IM...

I can atest to the fact that a reliable setup with a CTR cam and crower dual valvesprings/titainium retiners is achievable while hitting the 1/4mi track weekly and shifting at 8700rpm...

 

what do you know about the jdm itr intake cam? those are just now being sold on inlinefour.com. And you think adding the skunk2 im will also give me gains with those other components?

 

anyone?

 

chech out the current tech posts for more info on the skunk2 im. If you doing the itr cams than deffinetly do it.

 

yeah ive read a few of them, anyhow does anyone know about jdm itr cams as opposed to usdm? also what about head gaskets, are these a good idea to do?

 

1.- ITR cam are actually MILD cams.
2.- Valve float will not happen with stock GSR springs and stock redline.
3.- Valve springs are not the only thing that dictates what the redline should be. Other things like wear and tear, fuel efficiency, reliability, etc and looked at also.
4.- Everything is designed with a factor of safety. Take it from and engineer!
5.- If you are going to install cams, why not get both cams? I bought the exhaust cam for $135 SHIPPED.

 

what kinda times you running 1fastgsr? i'm planning on your setup. what brand stuff you using too?

 

are there more gains if you put both in? as far as id seen you only need the intake cam.

 

I am not a drag racer and I have gone to the track just once. I am still working on the launch.

Icebox, ITR exhaust, Carsound Cat, JDM ITR header
98 ITR cams, S2 gears, VAFC

With both cams the car makes HP all the way to redline. With 1 cam, it will drop off after ~7800 rpm. The exhaust cam does give more HP, but the intake cams gves 3X times as more. I am happy I have both cams.

where did you get the exhaust cam for $135 shipped?

 

someone from this board, stick
