im looking in getting cams for my gsr the gsr has hytech header and skunk2 IM and 68tb cai full exhaust just don't know what to get. I tryed searching on ht but something wrong with the search engine. I was thinking about running itr cams cause i got a P73 for free and the map should run good with the set up with what i got. just need some input and suggestions

 

i had a similar setup gsr head no port, sk2 pro 1 cams and v.t, sk2 pro series i.m portmatched to 68mm tb, aem itr 3'' cai,hytech rep header with fat dent on bottom, aem pulleys, 2.5'' buddyclub spec 3 catback, gsr block rebuilt with jdm itr pistons tuned on hondata s100 made 216hp and 150ft lbs tq! this was one fast motor i'll tell you that!

 

might want to research tb's more just to be as sure as you can be... see what kind of numbers other people put down with their set ups and see how there power bands are and figure how you want your power band to be... 68 might be too big especially for a daily driver but obviously it all depends on the set up and what you want out of the engine... but from what ive read you want to be careful about picking the tb size... just some food for thought.

 

Not tru at all ive seen 70mm even 72mm on unported heads on 1.8l blocks its all in tuning the motor and why in the world would you need a stroked 1.9l motor just to run a 68mm tb!.. BS. you shoud research more your self and i acually had my sk2 intake manifold on my stock gsr motor with bolt ons, intake, header, exhaust and then added the 68mm tb and it always drove perfect with no issues then it was built and tuned still with a 68mm tb, unported head and still a 1.8l making 216hp 150tq thats some food for thaught!

 

ok wait a minute, first of all you said your 2 cents and i said mine... neither of us can officially be right.. this is a forum.. both of us our stating our opinions from our experiences and of course they are going to differ, that goes without saying, just try to hold back from flaming on someone like you just did to me... its not fair or the right thing to do... i could see if my opinion was WAAAY left field or just some stupid ridiculous opinion but it wasn't.. my opinion had logic and made sense. so easy tiger relax

my intention was not to bash you or say you were wrong in anyway whatsoever and i didnt mean for it to come across like that at all but apparently you might of thought it did... but again... that wasnt my intention...

what was my intention was to give the man some food for thought... nothing more.. nothing less.

he asked for help in or advise rather in general.. not just from you.. am i right or am i right? thank you

very impressive numbers though... i cant lie about that.. nice set up!

 

get ctr's or 00-01 ITR cams...it would be best for what you have right now

 

i forgot to mention.. i purchased a hytech replica off of ebay and the welds were actually pretty good.. i was impressed.. so if i were you i would at least take a look into getting a replica before paying for a authentic one.

 

buddy club 3+, they have higher vtec lobes and longer duration then skunk2 stg1 and ctr/itr. you dont have to change out the springs or retainers but you should so you get the full potential of the cams because they'll make power pass your stock redline. after that get a good tune and you're set.

but if you're tight on cash then, ctr/itr cams would be ok too since you got the ecu already, but you need the harness conversion since its obd2. gl.

 

the OP never mentioned if he has an obd1 or obd2..and there is no point of going with aftermarket aggressive cams like the buddy club 3 spec cams with the stock valvetrain

 

sorry about that guys i got a 98 with is the obd2a i belive but why get 00-01 ITR cams why not 99 ?

 

Get CTR or ITR stay oem.

 

Get the CTR Intake Cam and call it done. The profile of the ITR & CTR Exhaust cam isn't much different from your stock GSR one.

 

i had a 95 with intake exhaust 68mm tb stage 1 exedy clutch light weight fly wheel and header and it drove perfectly fine

 

it really doesn't matter. people prefer the later cam because it has 3deg more on the intake at 1mm. on the dyno, you would never see it. if you can find a good deal on 99s by all means, grab them. the only issue with ITR cams is you either pay $550 for new ones or $300-350 for used ones. prices are really solid on these. tuning is also the easiest since a p73 program is near perfect.

An ITR cam would be a good improvement for your GSR. I am running CTR/ITR cams in my GSR right now 182whp/134tq. But from the parts you've listed drop the P73 and get it tuned. Keep in mind the P73 is based on an engine with 10.6:1 compression and yours has 10:1, not ideal but it would work. I would suggest ITR valve springs for added insurance with these cams.
What kind of exhaust? With the parts you have listed and a good tune you should be able to see power in the mid 170's with ITR cams. You'll benefit even more with an increase in compression, and that should get you into the 180's.

I also have an ITR Intake Cam ONLY, brand new, drop me a PM if interested.

 

i was about to ask the same question myself wich is better to run. I currently have a stock 2000 gsr with bolt ons myself. The mods are as follows megan racing 4-1 header with 2.5inch collector, 2.5 inch tsudo n1 catback exhasut from front to back with a magnaflow high flow cat, ngk spark plug wires, custom short ram intake. I have the skunk2 pro series intake manifold with a jdm typr 65mm throttle body and have the right parts for the intake install also have a hondata gasket, weapon r secret weapon short ram intake with ram air install these parts are not currently installed yet. I plan on getting a obd1 vtec ecu from phearable.net and the obd2 to obd1 conversion harness. I plan on getting cams but cant decide on ctr, or itr, or skunk2 stage 1 tuner series cams. I talked to a skunk2 csr tech and they told me the skunk2 stage 1 tuners would be better since i do plan on going turbo later on and build me a engine. my plan is for a 400hp turbo dd. Just need some input on the cams.

 

this is true. the p73 is just a basemap. normally they run rich, especially at idle. more timing and less fuel on a custom tune would probably be worth some whp. i have a p73 on a real ITR motor and i would definately tweak the map if it was tunable. i've seen as much as 10whp on a tuned jdm itr versus the p73. do keep in mind that 10whp is gotten somwhat at the expense of safety with bad fuel, 100 degree days and the rest.

 

if you dont wanna mess with the springs then get ctr/00-01 itr. they are the same but stronger than 96-98 itr cams. also get both intake and exhaust because it has been proven that you get more power with both cams. theres a post on team-integra.net that proves it.

thats what i'm currently running on, 00 itr cams with stock gsr valve train. then got a custom chip from xenocrome. told them what i had and they custom made me one. feels stronger than before. can definetly feel it pulling hard at higher rpm like 7000 and up but i have to shift at stock redline cuz i dont wanna blow my motor.

 

thanks you guys been a big help also i heard that you cant tune a obd2 ecu is that true or is someone giving me bs

 

you cant tune any stock ecu...it needs to be chipped. obd2 ecus are harder because they have more restrictions. best ecu to tune on is p28(92-95 5speed ex/si).

 

ok thanks for clearing that up for me

 

What year is your GSR? If it is a 94-95 you have an OBD1 P72 ECU which can be reprogramed. I am guessing the P73 is OBD2.

 

Get a good cold air intake, 2.5'' exhaust, skunk2 pro series stage 1's and make sure you have a good header. I got one for sale!!!
