Hi.. last year i found a pair of DC2 camshafts on ebay with a really good price, and i just baught them with the thaught of fitting them to my b16a engine. But then after realising that i need to change the valves, retainers, springs, head gasket, ecu, etc i put them in the garage and left them there.. Can anybody tell me if (1) They fit? (2) What exactly needs to be changed? (3) What are the results?
 
these wil fit your engine no problem.

you could go and change your valves and springs but this is not a must. you would only need to do this if you were goin to make your engine rev higher or making a higher compression. you should notice a little gain in power but if i am right you should move the limiter higher as the make power a little higher than the b16a2 ones
 
keep your stock valves, you just need springs and retainers and a minor remap.
 
Oh so i won't be needing to change the ECU? Cos obviously i want it to rev more.. And what about the cam pullys?
 
Several friends here have changed b16a cams for ITR ones, and i know they havent changed anything but the ECU* for the cams to work propperly, what year are your cams, for what i know 96~97 cams are less agressive than 98~

*Im not a guru but i would also polish (and port) the head, intake manifold and change intake pipe and exhaust (since im changing cams), and why not change the head gasket as well (for a spoon or mugen one).
 
The DC2 cams will work like someone already said. The thing about them though is that they will not make that much more power, they are still an OEM cam and designed for drivability and not extreme performance like something from Toda B's/C's or Buddy Club Spec III/IV would.

The B16B motor already has a lot of compression, so a motor with cams with a good amount of duration and proper tuning would really help out.

With what you have though, you may not see a big jump in power. You can still use your stock cam gears, valves, springs, retainers, the whole deal, that stuff should work fine. I would replace it anyway though just since you are going in there and doing laborous work, might as well put in all new stuff that you know is going to be reliable and worry free as long as it is all installed correctly.

What would benefit you most in short term would be a good exhaust header and a good intake system with a tuned or chipped computer. Those are the best simple upgrades for the B-series out there.
 
So... what you are saying is... If i just change the camshafts and ECU I should work fine right? But would't i have any valve bounce since im gonna have more lift from the b18c camshafts? And will the vtec feel like the itr feels eg. like the engine wants to come out from its engine bay? :) I think i would definately need to increase compression to really feel the difference? No?
 
can anybody help please as i need to be 100% on this and lots of opinions were posted..
 
I asked again, and you can use your valve springs, if you were changing cams to a toda B or alike, you would necessarily need to change springs for they would 'float', in this case the people i asked they have them with the b16 OEM springs.
 
these cams work very well in the b16a engine. there is no point in getting the itr valves as you need to get the head machined for them to fit and costs lots of money for no real gains. iv looked into this as im gettin ctr cams in mine. i have everythin vsprings retainers valves the lot but just going to leave the valves. was ment to fit them 2 weeks ago but still not got round to it lol. if i get them in this week or any time soon i will let you know how well they work and the performance

one thing first, Have you ever done internal work on an engine before? not to insult you, but it does not really sound like it. Cams are not like bolting a new header on or something, they need proper tools, installation, and measurement to function correctly.

It will work fine if you do a good valve adjustment. You have to lash the valves properly and make sure you are within the proper clearances.... I dont know them off the top of my head, but the cams should work, yes. You just need to install them correctly. you are not getting that much more lift. this is what I was saying in my first post, I almost see it as being pointless. You are better off buying aftermarket performance cams, it seems like you want the vtec to kick hard so get cams that will allow you to do so and a computer program that can handle the change for air, fuel, timing, and spark.

Look at some J's racing things....they have some very nice stuff that will all work together and will get you what i think you want. good luck

Oh thanks lumek4 it would be great to know how the new cams work.. As for CJM i did loads of overhauling on many different cars. The only thing is that i never actually tuned a car before so i admit i might not know some tricks like some of you guys do. I don't mind asking where im not so sure about things so... Its just that friends over here in my country recommended to change springs and retainers, ecu and a thiner head gasket so i thaught i'd ask over here whats the best thing to do. Did i do anything wrong or did it make me look like a complete idiot cos i asked these questions CJM ?
 
i guy on the civicjordan forum recently installed the ctr ek9 cams, and said it barely made any difference..

iv spoke to other people that have put them in and say they were good. from inside the car they say the v-tec noise is different a we bit more aggresive. they have all said on the 1/4 mile they have gained around half a second. but there is only one way to find out and that is for me to fit my cams and test them for myself. also if you dont get them set up rite after market ecu adjustible cam gears ect ect you prob wont get much out them
 
Oh wow half a second is quite a lot lum ek4!! I will soon put mine in and will let you know.. What Ecu do you recommend please and where to buy? Any links? And as for manifolds (in & ex) what do you recommend?

i know people that has had better gains than that. im sure R.V.M fitted a set to one of his civics before and he had good gains to. as far as the ecu it all depends on what you want out your car i.e fuel econ or launch controll. you could change to obd1 and run hondata witch alows u to re-map aswell. the manifold i would go for is the 5zigen 4-2-1.
 
you got any links from where to buy please lumek4? i use my car for everyday so i need some econ but i also love revs especially when a ford or a toyota come 2 challenge :p if you know what i mean :)
