What kind of gains can be made with type R cams on a jdm gsr(10.6CR) ? And will it be okay for boost ?

 

its fine for boost...Gains wont be much without a tune...

 

im talking about with a tune.

 

the gains will be noticeable..i run ctr cams in my car (00-01 ITR Spec)

 

have you any kind of dynos to compare in whp and wtq ?

When dynocenter.com was functional, there was a 96 GSR with an ITR intake cam (p/n 14111-P73-J00) and stock GSR exhaust cam. The intake cam with adjusted cam gears yielded an 11 WHP gain. There was a torque deficiency from 4400 RPM to 4800 RPM on that setup because the VTEC engaged too early. Otherwise, the ITR torque curve was better than the GSR throughout the RPM range.

wow

 

Good info Dogginator.

 

does putting in ITR/CTR cams in a gsr still allow you to pass smog?

 

ctr intake
itr exhaust


about 5hp gain.

I never had any problem with the sniff test. Heck, I even passed the OBDII dataport scan with my chipped P72. (Yes, it is OBDII with p/n 37820-P72-A02.)

 

Yes sir..... my high mileage motor with intake, intake manifold, ctr intake cam, cam gears, header, exhaust passed about 5 months ago. No problems what so ever....

 

they would be ok for boost, but running your GSR's you have would be better for a turbo'd car. when i had my boost'd EG, i sold the ITR's i had for GSR's and it ran better. easier to tune as well.

you would have made more power with the itr's

 

i actually gained by ditching them. couple thread below from a quick search on why. maybe it was my tuner, but you dont loose going GSR cams on turbo.

what kind of power would you be making if you also threw in some ctr or itr pistons along with the ctr or itr cams?

 

and would ctr cams make more power in the gsr than the itr cams?

 

I made 181 hp to the wheels with 01 ITR cams, skunk manfiold , mugen header, test pipe, greddy pe exhaust, cam gears and p08 skunk chip and VAFC tuned.

 

it seems like people only do the intake cam upgrade on the gsr motor. Does anyone know why this is so? Im saving up for cams on my gsr, (either itr/ctr) but if i should only do the intake cam, then that'll save me lots of money. what do you guys think?

The reason that they only do the intake cam is because it provides about 11 whp and the exhaust provides about 3 whp. I installed both cams and the ITR valve springs. (GSR intake valve springs = ITR exhaust valve springs.)

There are better options for power now than the Honda cams. I installed my cams in 2000, when the aftermarket options were few and of questionable quality.

well for me, this is going to be a boost application. So aftermarkets really isnt mush of an option. Wow I think i'll be pickin up just an intake cam from an itr or ctr and boost it.

 

ITR cams are great for boost way better than gsr but i thought ctr cams were for more of a NA application

Keep in mind that there are two versions of the ITR intake cams. The latest one (p/n 14111-P73-J01) used on the 00-01 USDM ITRs is quite similar to the CTR intake cam. The 97-98 USDM ITRs used p/n 14111-P73-J00.
