i do realize there are a ton of threads "similar" to this, but i havent found one "exactly" like this so here i go....

im putting a 2000 jdm itr swap in my car on the 16th of april and i wanted to do some upgrades before it goes in.

the head is getting milled, (standard not agressive, but im not sure the exact amount) and im planing on using a thinner head gasket, probably 1 layer.

the head is being ported and polished along with the intake manifold.


my car is my daily driver and will never see the track!

i have lots of the common supporting mods already in place....
j's racing intake, very large 4-1 custom header with 2.5" collector, bdl cam gears, bdl fuel rail, bdl fpr, bigger stainless fuel lines (not too sure of the size) 2.5" hks hi power exhaust with race pipe, p28 with hondata, blah, blah, blah

anyway, what im wondering is, my motor should be close to 12:1 compression.
so what cam can i use and get the strongest midrange power? peak power is second on my list but i will be reving to 8500-8900 rpm from time to time so i dont want my cams to fall off to early either.

i keep hearing that skunk2 pro1 and pro2 cams are great but only on larger displacement engines than mine. is this true???

i am also concerned with longevity and dont want to change my valvetrain everytime i change my oil!

gas mileage isnt really an issue
cost is a medium factor
reliabilty and longevity a major one
and midrange power is a must!!!!!!!!!!!

i dont want clearence issues nor campatibility issues, so i'd like to purchase the cams and valvetrain that are made to work together the first time.

i would also like to purchase these from one of our vendors if possible.

any advise that any of you may have is very welcomed.

p.s. the install will be done at trackmasters in huntsville and i plan on spending as much time getting it dyno tuned as it takes!

thanks in advance

 

A lot of people ask these questions and don't seem to find the answers they're looking for because they ignore one basic point...the cams themselves. There can be a hundred different questions about cams but there are only so many cams to choose from. The posts you search may not asnwer your question directly but they should give you enough relevant information about each cam to help you decide if it's right for you or not. For instance, if you want good driveablility and something that's easy to tune, you go with a cam that has stock or very close to stock primary lobes. If you want good mid-range, you have to go with a cam that has modified (bigger) primaries than stock and there's only so many of these which really narrows down YOUR search. All the performance cams have bigger VTEC lobes which give you top-end so you can look at the ones most people seem to run in a build that's similar to yours and go from there. Searching the posts and looking at people's builds will help get you close to where you want to be. Then it's a good idea to talk to your engine builder and see what they recomend vs 100 people on the internet.

Some cams I would probably suggest you consider would be RM M22x or M22xx, Skunk2 Pro 1 for sure...maybe pro2, Buddy club IV or V. Search these cams on here to get some feedback from different people's experience with them and look at the builds. Then ask your engine builder.

Honda engines don't seem to spend much time in Mid-range in general, they're made to rev and make power higher up. When they are in mid-range you're usually just cruising and don't require lots of power on tap. If you do you usually just gear down and go.

 

i think i actually read cam posts for about 6 hours last night and what i found the most were peoples builds that were larger or higher compression than mine so i asked. im very interested in the pro1's. my largest concern is my ability to take advantage of the cam do to my compression and displacement.

and thank you again 00Red_SiR

 

skunk 2 pro2 will give you the midrange you want and the top end. the pro1's are good as well but do not have the duration to continue to make power the the rpm's you suggested. so pro2's would be my suggestion.

thanks shawn

 

pro2's are too big for your motor IMO. and they require you to carefully degree and tune your motor to make sure you dont destroy your engine. something you seem to not want to do. clearances arent something out of your control, you degree them and set the cams where your clearances are good. sounds like you want a cam you can just drop in and not have to worry about. if thats the case, stick to CTR cams.

pro1 or m22xx gets my vote provided you check your clearances and take the necessary measures that are required when installing aggressive cams.

Pro2's require more displacement imo.

have you ran these cams in a 1.8?

how did you come to this conclusion they need more displacement mister smarty pants?

shawn

 

im def. not looking for a drop in application. i am willing to do what ever it takes as far as clearence is concerned. when its all finished though i want reliability. so any more thoughts???

how about pro 1's then???

pro1's are great cams as well as pro2's.

pro1's will not make as much peak as pro2's midrange should be about the same with either cam.

 

are clearence issues going to be vastly different between pro1's and pro2's? and will the steps required to tune be similar?

 

because he dyno tuned them both on 2.0L and 1.8L engines.

you dont HAVE to have more displacement, hes just saying they will work better with more displacement. you can run pro3's on a stock b16 if you like, but dont expect the best results. thats all hes saying.

they will be similar yes. the pro1's will have a little more clearance than the 2's if youre going to take all the steps necessary then it shouldnt be a problem. i like both of these cams. i run the pro3's where the clearances are much closer so i wouldnt suggest you running those.

buy the proper valvetrain and it will be a nice piece.

im not telling you information from reading by the way. ive ran the following in my engine on an engine dyno. ive also seen all these ran in a 1.8ltr engine as well on the same engine dyno.

crower stage 2
rocket m24
buddy club 3+
skunk2 tuner stage3's
skunk2 pro1's, pro2's and pro3's

good luck with your build.

would you actually lose power in some places by running one of these cams over stock itr's or ctr's?

 

tell me this???? what cam doesnt run better with more displacement??

even a ctr would do better with more displacement..

no you wouldnt lose power by running these.. you will gain power everywhere..

he actually said they require more displacement. which is bullshit. more displacement would obviously be better i wouldnt argue that. as i have a 2ltr..

 

should i still shave the head then? or would i be better off with a little more room for adjustment?

 

i would say just take a slight layer off to make sure its flat. if it was a race motor then shaving the head down for compression would be fine.

 

its not a race motor, and it only has 17k actual miles on it.

 

We've made more power on mild 1.8L's with M22X rocket cams than any other cam.

Pro-2's made less power compared to BC3's on a stock ITR motor. Pro2's should be run on high compression 1.8's - 2.0's.

Pro1's are also great midrange cams, with terriffic throttle response.

he said 12:1 above..

 

is 12:1 correct with a jdm itr motor, milled head, and 1 layer head gasket?

You'd have to plane your head roughly .030 thou with the 1 layer head gasket to get to 12:1. CC'ing the chamber is the only way to know for sure.
