I'm interested in picking up a set of cams for my ride and I was wondering what is a good choice. I was thinking of skunk 2 but I would like a second opinion! Any suggetions would be welcome!

 

Hytech has a sweet set of cams they have been using on GrandAm race cars for a couple of years now...not too aggressive, should be sweet.

 

hmm maybe I should have put more thought into this post...ok the top criteria I am looking at is:
1.emissions test friendly
2.reflash friendly
3.streetability/daily driving

 

If you are swapping cams you might want to look into k-pro instead of hoping for a reflash to hack it.

 

If you get cams you need to get KPro. The Hondata reflash won't properly tune the car for the new cams; it's designed for stock internals.

 

oh well it was too good to be true, cams and a reflash maybe it's for the better the euro r kit is starting to look quite appeasing! Thanks for the info everyone!

 

Skunk2 stage 2 cams for K20A3 have the same primary lobe as TSX cams, but high cam profile is much better. That means as long as u stay out of VTEC zone, u are quiet, friendly and economical. The car would act like its 100% stock. However, getting cams requires K-pro, CAI, good header, high flow cat or testpipe and new cat-back exhaust. IE u have to make breathing and farting as easy as possible for your car. The price of the cams is also kinda steep... especially if u include installation, new springs and retainers and tuning on dyno. Yet the gain would be..... 20HP??? I mean unless u got pulleys and all breathing bolt-ons and RBC intake manifold and u are all out of ideas.... then go for cams



There are reflashes that work with aftermarket cams for RSX-S, but not the TSX

 

Stay away from skunk2 cams because alot of K20 guys have had serious problems with them. Crower, Blue Print, Buddy Club, IPS, Toda and Hytech are all good. Blue Print may be the best bang for the buck and IPS cams have made the most HP on moddified K20/K24's. Blue Print stage 2 Cams will run you $750 brand new and 1K with valve train. You'll need more than just cams though. You'll need a good "race" header as well. And dont forget KPRO!

 

Do you guys think Hondata would come up with a dedicated reflash if enough of us got cams? The reason I ask is cuz I'm not going to get Kpro because you can't smog it out here, but the reflash is smog test friendly.

 

^Interesting idea....

 

^^You or anyone wanna run it by Doug (seen you on the hondata forums)? I'm by no mean an expert, but I have heard of it happening for other hondas.

If it were in stages, even better. Again I'm no expert about any of this.

 

I just remembered something... TSX's VTC mechanism cant go past 25 degrees... getting cams with such a pathetic cam angle would be a bit useless and reflash cant make it go past 25 degrees even if the mechanism was swapped from RSX. Arghhh. I guess k-pro is indeed the only option, but if the reflash worked, I would sign up for it... I just think that current "bolt-on optimized" reflash is not good enough to make a car go fast since it does not change peak HP. Cams would change it all

 

^^right. I've heard that before. Oh well, just a thought.

 

^ I would love to have cams, tho. I pay a lot of respect to N/A tuners bc their job is hard. Extra 10 HP without adding PSI requires some thinking

 

This is not true at all... you can make good power without advancing past 25 degrees. Some cams dont even need more than 25 degrees and some dont need anything past 35 degrees. The reflash cant change the VTC past 25 degrees because thats the limit of the TSX's VTC period! Someone also made about 240whp with a K24 block and a K20 head using the 06 TSX intake Cam, Intake manifold and 25 degree VTC. So you can make pretty good power without going past 25 degrees.

 

I actually got this all mixed up.. one of the guys on K20 made 250whp with stage 2 cams and valve train in his frank k24/k20. He has the stock rods and pistons from a CR-V which are 9:6:1 with RBC and 3' cat and exhaust and tuned with K-Pro. Redline is at 7600 and VTC is stock at 25 degrees. So you dont really need to advance that much past 25 degrees to make power.

So if you had 06 TSX cams you could make around 220HP since compression is a bit higher. Some cams dont need that much advancement when tuning.

 

^ thats a Frankenstein motor and yes, some cams dont have to advance far, but most of them like to advance. Also, each cam would need its own reflash... how could we decide on which cams to get ?

 

Its called a frank because they use the K20 head but its basically a K24. The head design is the same as the K24. There arent any cams out specifically for the K24 but you can use K20 cams. Just like how K20's use TSX cams. So if you have a TSX and you use K20 cams and valve train, thats basically what a frank consists of. So those numbers ^^ are what N/A TSX's are capable of. Some tunes dont see past 35 degrees and some see alot less than that.

 

K20A3 has a very similar head as K24A2 and its primary lobes are exactly the same as TSX's. That means if u were to buy cams for TSX, u should buy those for 02-05 Civic Si with K20A3 motor. u would also need springs.

Back to the topic of software...

 

You do know when going aftermarket with cams, if you get K series cams they fit all K series motors right? Why would you put SI cams in a TSX?? TSX cams are more aggressive.. and you wont need any springs going with Si cams.. you know nothing about what your talking about. And this thread isnt about software its about Cams.

 

OK precyse, RSX-S has lower primary cam profile than TSX for economy's purpose because it has 310CC injectors. Civic has larger primary cam profile and its same as TSX's primary cam profile. It also has 270CC injectors whereas TSX has 310 CC injectors. Why use Civic's cams instead of RSX-S' ? Because if u read Hondata's tuning page u would have know that primary cam profile of ITR/RSX-S is lower than TSX's so if u drop those into TSX, u will lose low end power and torque, but gain at the top bc ITR's high cam profile is more agressive than TSX's. That is why u want to go with aftermarket cams designed for EP3 Civic. They have same low profile of cams as TSX, so u dont lose low end anything, and since aftermartket cams will for sure have more agressive VTEC, u will gain at the top. I didnt mean stock cams from EP3 Civic, of course....

 

They dont make cams designed for the EP3 Civic... Every company makes 1 cam.. and they fit "ALL" K20 and K24 motors. They dont make K20a2 cams and then make K20a3 cams.. they dont do that. So like i said.. your making false statements. ITR cams use to be more aggressive than TSX cams.. 06+ TSX cams are more aggressive than ITR cams.. I believe the 06+ TSX cams are the most aggressive cams honda has at the moment or maybe they use to be.. And the ITR cams hondata used wasnt the reason why hondata lost power in their testing, it was due to not having a race header. They used the comptech header and intake only.

And why are you talking about injectors?...haha.

 

I am talking about injectors to make sense why they gave lower primary profile to ITR than EP3 Civic. Check out Skunk2's or BRian Crower's official web sites. They make separate line ups of cams for K20A3/K24 motors and K20A2 motors. Do that research and then come back.

 

The K24a motors.... not the K24a2 motors! You do more research . They mean its for the Accords and CR-V's.. they dont even use the same i-vtec system as K24a2's and K20a2's. Read up some more and then you come back!

 

Let me help you since you need guidance. Go back to BrianCrower's page and look at the difference. Under K20a3/K24 cams they list which cars and it says CR-V, Accord and Base RSX. Then go to K20a2 cams and you'll see how they list "TSX", RSX-S and the JDM Civic Si. Not the USDM Civic Si that has the K20a3 motor.

 

And why does Hondata's tuning page say that RSX-S has lower primary cam profile than TSX? Thats right... because they are different.

 

If your talking about stock cams.. i never said they were the same. And the arguement isnt about the RSX having a lower primary cam profile. Its about if you want to use cams in your TSX you'll need to run with 06+ TSX cams or if your going after market, you'll need RSX-S cams. The only cams made to work with the RSX-s and TSX. So stop informing people to get K20a3 cams to work in thier TSX!

 

well it looks like we are talking about the same thing without understanding each other... yes, the cams are interchangeable and yes stock K20A3 cams and K24A2 cams have the same lower cam profile. When it comes to aftermarket, go for K20A2 cams if u want low cam profile to be close to stock. Go for aftermarket cams designed for K20A3 if u want lower cam profile to be higher than TSX's stock low cam profile.

 

Listen man, k20a3 cams aren't the same as the k20a2 and k24a2 cams. Those motors use a different i-vtec system then the k20a3 does. The most aggressive oem cams is the 06+TSX. The k20a3 only has vtec on the intake side and the other two have vtec on the intake and exhaust. You are making people confused with this k20a3 stuff man. Why would some one with a k20a2 or k24a2 head want k20a3 cams, it doesn't make sense. If you want oem cams, 06+ TSX cams is the way to go. It will still retain stock reliablility.

 

Thanks for the help.. this kid must wake up with a headache everyday! He's hard headed! I dont know how he thinks a 2 lobe cam will work in a 3 lobe head! And he really tried to make it make sense.. He just found out what a car was a few months ago, now he thinks he knows everything about them..

 

Hondata will not make ECU's tuned for every specific cam profile out there.
thats the whole purpose of KPRO

 

what if i were to swap in the 2006 TSX intake and exhaust cams into my 2004 TSX and run the reflash? Mind you would I have to run the reflash for the 06 or can i still stick with the 04-05 reflash?

 

You need just intake cam , exhaust r the same on 06 , and a 06 reflash for it to work properly.

 

You can't put the 06 reflash on a 04 ecu. The throttle body, intake manifold and valves are also upgraded in the 06. So is the exhaust system and cat. You won't change your engine into an 06+ with just a cam swap, and either reflash won't be expecting that configuration.

 

What about Kelford? I heard that Kelford camshaft give a good gain of hp and torque for K series motor. I am considering to get 179-A or B for my 04 TSX.

Check it out on Civic SI from importuner: http://www.importtuner.com/tech/impp...nda/index.html

 

You will still need to tune the car to it - they will make changes beyond what the ecu cam compensate for.

 

Yeah you are correct! That's why I am waiting for FlashPro. If FlashPro is not available then I might have to go with K-Tuned KPro.
