i just searched, and found nothing but FS ITR CAMS WTB ITR CAMS, and got fresturated so im asking you guys, how much of a difference does 00 ITR cams make in a gsr? is it even worth the 350??

 

i don't know too much about itr cams, but from my experience with brian crower i can say they are very worth the money.

 

thanks!

but can anyone actually vouch for them?

 

Speaking from my own experience with both of my GSR's I had ITR cams in them only cause I got them for free. But when I got a set of Blox B's for $300 for one GSR and then another $325 got me some BC3's in the other GSR. The ITR cams gave a bit more throttle response over the GSR cams and a little more top end, but for $350 you can get some more aggressive cams that will net you more bang for your buck than the ITR cams.

 

but does stage 2 and 3 cams not require new valve terain??

i know 3 is required, but is stage 2 just reccomended?

I want to help you, first with clues. What I mean is that if you want to get good with this stuff, then stop calling it stages when trying to figure out how aggressive a cam is. Next, if a cam manufacturer recommends a valvetrain kit, then get it.

Brian Crower would be your best bet if you ask me since they have various options that other cam manufacturers don't (i.e., steel retainers for dual springs that are probably a little lighter than the ITR retainers so you save loads of money.). Brian Crower has the best prices also from what I can see. The best thing to do is call Brian Crower tech support and have them recommend you a set of cams. They'll get it dead on.

I hope this helps.

it is worth the money for me. i bought brand new oem CTR/ITR 00-01 (same spec as CTR), i paid about $600 and then get it tuned afterwards, i can feel the differences. and u dont need to upgrade the valve springs and retianers. and the idel will be normal

 

On a first gen b16a and some others you need to upgrade the LMA's. If this is a gsr motor, then don't think there will be any problems.

Might want to rethink this as well. B16 LMAs limit you on BIG cams, not on stage I cams. You really dont want to upgrade any cams without the correct valvetrain (Type R dual springs for ITR/Stage I cams; aftermarket with anything larger then that...."that" being around 11.5mm on the intake and 10.5mm on the exhaust). Ofcourse your redline will also play a role into that as well. If its on a ls/vtec that you are revving to 7200, then you can get away with a bit more.

Either way, ITR cams are a great upgrade, many people have shown to make as much power with them as others do with most stage I cams.

 

apparently nobody checked these out or you wouldn't be asking questions about valvetrain recommendations. <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by integrawow &raquo;</TD></TR><TR><TD CLASS="quote"> stop calling it stages</TD></TR></TABLE> why not? if you read my link thats how they are noted as. stage 2 fi, stage 2 na, and stage 3 na.

I must worry about that site. Look at this dyno:
http://www.briancrower.com/mak...shtml

Notice the conditions:
<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by briancrower.com &raquo;</TD></TR><TR><TD CLASS="quote">BC0012 – B18C stock block and head, 81mm bore/11.5:1 compression, BC0010 spring/retainer kit, Hondata s200, ITR intake manifold, Edelbrock header/exhaust, sprockets set at -1 int/0 exh, 91 octane pump gas.</TD></TR></TABLE>

The data look reasonable, but the details are quite flawed, i.e. ITR IM on a stock GSR head. Then they also have an 11.5:1 compression ratio. I assume that the top line is the B18C1 and the bottom line is the B16A. The VTEC transition on the B18C1 looks like it occurred too early. I would really want to see an independent dyno with those mistakes.

 

different companys have different "stages" and a different variable of lift/duration to go with those stages

In general I tend to agree about the "stage" thing, however with cams most companies run very comparable "stages"....most fall really close to one another. Factor in ramp angle and duration (longer duration, less lift vs shorter duration, more lift) and next thing you know, they are all very very similar on power output. Now all of the above "should" play a role into the cams you pick, however you'll be hard pressed to find many detailed specs on ramp angles...which leaves you with lift and duration, of which most people dont know what they need.

 

I bought CTR cams for my gsr.... made a good difference between 6k rpm to 8k rpm.... i jus slapped it on there... and i can feel the defference.

 

this is all VERY helpful information!

one more question. ive got a hookup for some pretty cheap skunk stage2 cams, the website says that its recommended, if i where to run stock terain with these cams, and eventually upgrade the terrain would it be bad for the head?

 

if you are looking for some mild gains for street use....i think itr cams are worth it...

 

Definitely good for n/a but can actually be too good, which in turn harms the motor for boost.

 

ITR cams are worth it, I put my 01 ITR cams in a couple weeks ago with the ITR intake springs and GSR intake moved over to exhaust, and from personal experience I love them. Not only does VTEC pull a huge amount more now, its easier to deal with OEM cams and not have to worry about degreeing them.

I know someone making 654hp to the wheels on ITR cams bossting at 22 psi on 1600cc injectors maxing out the turbo thats rated at 600hp, go figure ITR cams being bad for boost.
