if i was going to install civic type r cams into a b16a do i need to replace anything else like the valve springs etc.... or will they fit right in do a valve adjustment and i am ready to go thanks let me know

No need to replace anything, unless you want to reaplce the LMA's while you're at it.

exaclty, you can see what will happen in this thread here

thats my friend, you can p-m him and he will let you know haha that stuff is important, youll save money in the long run

 

You'll also notice many people run CTR cams in stock B16's with 9K rev limits with no problems...and so do I. I even misshifted into 3rd instead of 5th and was scared shitless cuz of mechanical overrev but everything was fine. On a street car, the stock B16 springs will be fine. If you want more insurance then upgrade the springs one step up. On another note, you don't want to go too stiff on the springs either as it will wear out your cams.

 

i like insurance....i floated a valve with my itrs on a stock b16a head. i hit 9000 rpms and it let loose. i floated a valve. i would just upgrade... its too easy to do it and one less thing to worry about

 

lets clear something up,

You do not need the valve springs or retainers unless you are going to rev to 9k,

ive ran these cams for 3 years with no valve springs or retainers shifting at 8200k without any problems.

And fyi there is no reason to take these cams past 8500 thats where they stop making power, anything else is just a waste on your motor.

 

Get an ITR valvetrain at least... Don't risk it!

 

Its my understanding the stock intake valve springs are actually stiffer than the ITR's. The ITR has lighter valves and a slightly softer spring.

I think all thats really necessary it adding extra springs to the exhaust side as many of them have only single valve springs instead of dual.

Agreed, however mistakes do happen... for instance at WOT in any gear and you are about to shift (at say 8K rpm) and all of a sudden there is a little bump you roll over, this can cause the rpm to blip and reach over 9k rpm. Yes there is no point in taking a stock B16A to over 8200rpm, but little mistakes happen so it would be a good idea to strengthen the valvetrain while swapping out the stock cams. (IMO)

 

so if i am not going to shift above 8200 i can just throw them in do a valve adjustment and i am done right ?

CTR are the best, and i think the 2000 and 2001 ITR's are the same.

Get the CTR's bro, more aggressive.

 

I did the ITR springs and retainers just to be on the safe side. I think a few years ago people suggested moving the b16a intake over to the exhaust side since it was a single spring, and at least getting the intake side of the itr springs.

CTRs are slightly more aggressive, I could swear I've read somewhere that the ctr's were drop in, and didn't need to be tuned unlike the itr's.

Someone else said it but, 2000-2001 itr's are the same profile as the ctrs.

I think what I said is right, I haven't thought about this for several years

 

alright thanks, also do you think i will still pass smog with the ctr cams ?

you could do that same thing with stock cams, if she has the stock ecu she wont be going over 8200 unless she mishifts,
