I notice that the JDM ITR '01 specs intake cams duration at 12.0mm/ exhaust cam at 10.5mm...could it fit in my B20Vtec JDM B18C1 bybrid?...

 

dpends on what head your using ? if you have a b20 block with a b series head i see no reason the would not work....maybe if u have a b20 head i could see them not working...but i still think they would

 

Sorri fellas...i meant the DC5 cam specs...

 

I would assume they would work fine (I haven't tried so I can't say for sure). You'd be best off upgrading your valvetrain and computer along with them to take advantage of the addition rpm those cams can support but aside from that? I don't believe there would be any issue with a GS-R head and a B20 bottom having interference issues, the B18C1's combustion chamber is smaller but it shouldn't be an issue. Find a good deal on the ITR stuff or you just don't want to go with aftermarket cams?

 

cheers andy...i was contemplating on aftermarket cams as advice by MrFatbooty...but for a daily driven car i am trying to balance between performance and gas mileage...so tis either the CTR or DC5 cams plus a cam gear...next on my list would be a ITR head, Intake manifold and TB...what do you think...

 

Cams from the DC5R will not fit in PR3 head ... K series vs. B series.

 

Someday I'll learn the new chassis codes. I'm assuming since he mentioned '01 ITR that he was refering to the older Integra style chassis. I just know EF/EG/EK/DA/DC and use those, I don't know the specific model numbers.

If you stay away from the higher level track cams, you can actually get pretty good performance on the street with an correctly designed cams. As far as I know, the Skunk2 stage 1 and stage 2 cams both have very useable powerbands. I was actually looking into a set for my '92 CX/B18C1 hybrid before it was smashed. I'd recommend a valvetrain upgrade with any upgrade but I've heard and seen dyno plots of good numbers from Skunk2's stuff.

I don't know if I'd spend the money for the ITR head or not. For what your going to pay to get it, you'd probably be better off with some porting work on your GS-R head and a good valve job. With Skunk2 making the ITR manifold knockoff, you also have a good manifold to upgrade to as well. A lot of people who I've talked to who have upgraded have been happy with it. I'm not really sold on TB upgrades, I haven't really seen verifyable numbers associated with them (usually installed with other modifications so don't know what difference the TB itself made) but for the money, it's probably worthwhile.
