i know this has been discussed before, but i would like to clear some confusion.

i'm switching my gsr intake cam for a itr intake cam. i understand that the gsr's already dual valve springs on the intake side, where it will actually matter. now should i go ahead and get itr valve springs or just stick with the stock valvetrain?

i have no vafc, cam gears, etc... i will also be using the stock redline. is there anything else i should have done or know about when doing the install (cam caps, stiffer outer or inner valve springs, etc...)? any help would be great, thanks.

 

To my knowledge, if you don't rev higher then stock gsr redline you are fine. That is how my car is set up.

 

Yes, you should be fine with a stock revlimit but you really won't be getting the most out of your cams until you get some ITR valvesprings and raise your revlimit.

 

so are you saying that just the intake springs are good enough or the exhaust as well.

because i was going to fit both ITR cams ,will that be ok?

 

If you are going to fit both cams and want to rev past your stock revlimit then you need to upgrade both intake and exhaust springs.
The ITR exhaust springs and the stock B16 intake springs are THE SAME so most people just move the B16 intake springs to the exhaust side and buy new ITR intake springs for the intake side.

 

at the present moment, i'm just getting the intake cam and will not be reving past stock redline.

i have yet one more question. since i am getting an intake cam and i already have a spoon air filter, will i need to purchase a FPR? would an intake cam and intake make me run dangerously lean? if so, what should i set my fuel pressure to?

 

Each car is different so it's hard to say of you'll be lean or not. But if you are staying stock otherwise, I say it shouldn't be a huge priority. The only way to truly know is to get the car dyno'd and have the A/F ratio checked. You can probably get baseline runs with the A/F so you save a few bucks.

Then eventually when you are ready to upgrade you can get the exh cam, cam gears, VAFC, FPR, Fuel pressure gauge, dyno tuning, etc.

 

You really don't need to rev much higher than a gsr to get power out of the itr cams because the itr's redline is just a tad above the gsr.

even thought the ITR and CTR intake cams are quite similar, why dont you just go for the CTR...its like an extra $15...and the ctr cam has more lift or duration...one of those.

 

well i got a pretty good deal from a buddy of mine who owns a shop. i got the itr intake cam plus install and valve adjustment for $210. it's a used cam...but i'm still not going to argue such a good price.

i was just wondering if i needed the FPR or if the stock setup was fine for the cam.

get it when you take your car to a dyno...even it you get a fpr, you shouldn't mess with it. the car should be ok even if it is running a little lean....i think...

The 00-01 ITR cam is the same as the CTR cam. Below 2000 the the CTR would be better.
