im really leaning towards ITR cams for my b18c1, what do you guys think?

will i have to upgrade my valvetrain? even if i keep my stock redline? also, will keeping the stock p72 ecu with the cams, limit gains? how should i go about this? and what are some setups that work for you guys?

thx in advance.

 

I've been thinking the exact same things as yourself.

 

No, u won't have to upgrade your valvetrain until u decide to raise your revlimit.. About the gains, sure you'll gain mid and top-end, but as usual, the more you put into the breathing process, the more gains you will get..

 

Yeah guys I also have a B18c1 with stock ecu but wondering what program is better to run in a 99 gsr w/ITR cams or CTR??

 

Careful with the CTR/ITR cams some are the same spec. Intake I believe, Check with WAFFLES, he knows.

As far as Valvetrain, again mentioned above as well, only when you plan on increasing your rev limit do you need to upgrade.

The best program to run is always Custom. Or use the stock ECU and get a VAFC so that you can program your self and still have to option to change.

Cams: 2000-2001 ITR cams (intake) are the same as CTR (with 1 degree less duration - possibly) while 96-99 ITR cams are 3 degrees less than the CTR cam. 00-01 ITR & CTR cams have 2 engraved rings on the distributor end of the intake cam while the 96-99 ITR cam has one engraved ring. DON'T pay xtra for the CTR cam when you can get a 00-01 ITR intake cam - & yes the exh cam is the same for all R's

Valvesprings: get ITR intake (inner & outer) valvesprings only (mike ie typermsm @ IPS had them for about 80.00) & swap your GSR intake to the exhaust side (ITR exh springs are the same exact part as GSR intake springs) that way you can get the most power out of the ITR/CTR cams if you raise the redline

sorry for the book , best luck

great info guys

i do not plan to raise the redline (8100) so im pretty much set as to what im doing....ITR 00-01 cams with no valvetrain work.

im still a tad back on the ECU question and what to run

can i get a vtec controller and raise the vtec say around 4.8k? what about the 2ndarys? just run a skunk intake manifold and then just run an ITR ecu?

what are some of the things you guys are doing?

thanks in advance hybrid brothers

 

Definatly get the Skunk 2 intake or a Type R.

Once you do that switch to a Type R ecu and get the VAFC.

and have a good time on the dyno.

 

can i run the GS-R mainfold/ITR Cams/V-AFC with sufficient gains?

 

If u have someone competent, someone who likes taking care of their customers and willing to satisfy you since u are paying THEM for THEIR time, there are indeed sufficient gains to be had with the stock manifold, itr cams, vafc, and don't forget cam gears..

The cam gears should be adjusted to how YOU want your car to perform (not just peak horsepower), but take a look at the torque curves per each setting and choose what u want.. And the vafc is there to raise your vtec to 5100-5200 (due to the drop you will notice on the dyno since ITRs engage vtec higher than our 4400)and somewhat "tune" (i use that term loosely with these piggybacks) your fuel curves.. Remember all of this is only recommended if u can get your *** to a dyno.. If not, just get the cams with the stock cam gears and forget the rest..

thanks a lot.
