i searched but couldnt quite find exactly what i was looking for so i figure its worth a shot to ask someone with first hand knowledge. i am going to be putting my new itr cams in with omni valvesprings and retainers. i have talked to a few people about the hp. gains i can expect but ive gotten really broad answers. i have heard from 2 to 5hp all the way to 15. does anyone here have any first hand knowledge (dyno, 1/4 times ect..) as to what i should be looking to gain? i didnt pay for the cams either just traded my old nitrous setup for them so i think its worth it no matter what since i HATED nitrous

 

It will definitely pull hard all the way to 8,000 rpm, and will especially help in the higher rpms. VTEC will also kick harder. I picked up 2 tenths with the cams on the 1/4 mile. Most people will tell you that you'll see better gains with the CTR cams, which is true, but these are still a great upgrade.

 

itr cams will for sure help u over the gsr cams. my brother has a 4 door 99 gsr w/ chip obd 1 ecu,header,cai,& exhaust and run a 14.80 w/ itr cams.b 4 w/ gsr cams his b.t was 15.30

 

good street cams for mild builds and cant go wrong w/ honda parts

 

i gained 3.3 wkw going from stock to ITR cams in my gsr...

 

thanks guys i cant wait to get them in

 

U need a ctr Intake cam its the most agressive intake cam honda makes for the B

 

Do you need to change anything else when doing that swamp? Dyno? ecu? And what about the 2 butterfly of the GSR? Cause I know ITR has a single stage over a 2 stage design intake manifilod?

Or you just throw the ITR there and that it? Tell me everything please!

 

Would it be overkill to have a say CTr intake cam wit ir exhaust on stock gsr valvetrain revving to 8200 rpms!?

 

do not forget that gsr valvetrain on the exh side is single spring. I would not run ANYTHING but gsr cams on that. On the intake you are fine, I had type R cam for years...

that single spring wont hold up?

 

It might hold up....it's recommended that you upgrade to dual exhaust springs though. Especially if you plan on raising your rev limiter in the future. On an expensive engine, like the gsr, I would not take the risk of something that MIGHT hold up.

Also, I believe that the 98+ Jdm ITR ran the CTR cam. The difference between the two I can tell you is great. I have the 97 ITR and a friend has the 98, his crossover is a lot more aggressive than mine.

Somebody can teach me about that swamp what exactly I got to do to do it properly??

 

00+ ITR = CTR cam

 

upgrade valvetrain to itr and you'll be fine. slap in the itr cams and your ready to race! not much to it

 

so to run a ctr intake cam and a gsr exh. cam would be fine on the stock valvetrain? would the gains be worth it?

 

yes

 

what about fuel mapping? what obd1 ecu program would be best to run?

 

where are the gains in the exhaust cam or the intake one? would the gains be noticable or worth it just to put in the intake cam and leave the gsr exhuast one? if we are only talking 1 or 2 hp i may as well just leave it out so i dont have to get new valvesprings/retainers if i really dont need to.

 

I've been running the stock gsr valvetrain for over 1.5 years with my itr cams. Not that I would recommend it, but I've hit 9000rpm quite a few times. No problems.

 

Would cam gears be a good idea to mate them with the ctr/gsr cam combo?

Yes, what map or VAFC settings should be used on a GSR with 00+ or CTR cams?

would putting both in make that much of a diffrence? like if you just have the intake cam is that the cam thats making the hp or is it mostly the exhuast one?

 

you can run both intake and exhaust on gsr valve springs as long as you dont raise your rev limiter. i know because i did it on my 130,000 mile gsr motor. ctr cams alone dropped my 1/8 mi. times from 9.39 to 9.15 and then i put in cam gears and set them to +4, -2 and put in a lightweight flywheel and dropped my time from 9.15 to 9.01. never dynoed it.
