Hello i am currently runing on a B16a2 engine and i was wondering is the exhaust camshaft from my b16a2 the same on the B16b type R and only the intake camshaft is different. if so can i just buy the intake camshaft off the b16b and swap it in to gain more power.. with ctr or itr valve and retainer. BUT will i even gain any power or torque... my mechanic said that its a good upgrade, please helphttp://www.ek9.org/forum/images/smilies/aag.gif
B16a2 Upgrade help needed

thats what i was planning on doing ctr piston ctr cams and valve n retainer to get some more power will this hurt my motor if redline to much or will it be the same since it has somewhat stock jdm parts
are you sure cause im just saying here a lot of people telling just to get the intake cam only cause thats the only difference but you may also be rite. thanks i wanna the fact please thanks

If you put ek9 pistons on a B16A I think you have to take the block to the machine shop so they can make the pistons fit? Right? I think it is not a direct "swap"
Correct me if I'm wrong.

You are partially right. The EK9 pistons is not a direct 'swap' with the standard B16A pistons. To make the EK9 pistons fit onto the standard B16A conrods, the end where the pistons fit onto has to be machined slightly (1mm on either side, if I didn't remember wrongly). Nothing needs to be done to the block.
Not at all. I've the EK9 cams, pistons and valvesprings in my 214,000km-old motor for more than 7 years and it's still running strong (dyno-ed at nearly 200bhp and 180Nm (nearly 133 lb/ft) just earlier this month).

yea you will feel more torque midrange,i done the following to my b16a2...
oversize ek9 pistons 81.5mm (nippon) block removed!
dc2 type r cams
head skimmed (lots!)
mapped via "crome"
also done other bits like arp bolts etc but didnt change the valvesprings or
retainers as my redline is set at 8500rpm which stock ones can take,if going
higher redline then deffo change!
after my car was tuned via "crome" on p28 ecu it felt like a different car,good tuner helps!
lots more torque esp around midrange compared to before and gets going quicker so dont need to wait till tec kicks in before it moves.
it made 185bhp and 123 torque which i think is about right,could get more
with wilder cams but its daily driver and this set-up suits my needs
goodluck with your build buddy

sounds good with the torque im looking to aim about the same a integra ls and you basically got it. well so far i have the b16b cams waiting for me at my mechanic shop he's selling it to for 200 USD only 55k was on it with free installation, so as far i know i need to buy some retainers and springs and piston and bored out the block. CORRECT.

For sure. No doubt the characteristic VTEC mid-range dip is still there, it's better than stock.
how about the ITR camshaft whats the difference between itr and ctr cams??
The only difference between the ITR and CTR camshafts is in the intake cam where it has 2 (or is it 3 degree more) in terms of duration. The ITR exhaust camshaft is exactly the same as the CTR exhaust camshaft.
Incorrect. If you are fitting the standard-bore (81mm) EK9 pistons into your B16A, you do not need to bore your engine block. Just need to machine your stock B16A conrods slightly to fit the pistons. Valvesprings and retainers are not a must if you are keeping with the stock redline, but they are good to have for peace of mind.
