I was planning on getting some ITR cams.. but i found CTR cams for sale for a pretty good price new, Im wondering if these 2 are the exact same... (CTR cams = ITR cams)? or does one produce more power?

I dunno any help would be useful

What type of ECU do you suggest for a mild setup? I have CTR cams w/gears, and the usual I/H/E. I read a little about the Hondata s100, and its said to be the correct way of tuning your car. The hondata can be pretty pricey, so i was looking for maybe a chipped p28. How do I know what fuel map to get for my setup, and who to get it from. thanks for the help guys!

There is a man named Kenji who makes programs and chips ECU's. If your in OBD2 mode than your going to need a harness to convert your system to accept the OBD1 ECU.

Email him with your setup and he will suggest a program and chip a P28 for you, for a reasonable price.

Either that or save for the Hondata and you'll be twice as happy.

A VAFC will help as well.

So with a hondata ecu, will there be varying points with which Vtec engages? because there are far more Vtec engagement points with the stock ECU as opposed to one using a V-AFC. Is it possible to tune a V-AFC to an OBD2 vehicle? I read that OBD doesnt take well to tuning.

Is it absolutely safe to run CTR valvetrain with Jun2 cams??

i mean the vtec lobes measure 12mm!! wouldn't it bind??

www.importreview.com tested the CTR valvesprings....and it binds at 12mm of lift...

so which is which??

If you are worried about binding with the 12mm lift, than run the JUN valvesprings.

You won't see the cams make power too too high in the RPM range, so with ITR valvetrain and an agressive yet appropriate redline, the ITR springs will be fine.

Too stiff a spring is no good either. Madtown learned this when using the Portflow springs on his Toda B's.

hmmm....because i'm very tempted to get toda bs....but have already bought the ITR springs (inner and outter)....and i'll be keeping to the stock redline....since toda bs have great midrange.

A lot of other cams have great midrange too. Toda is beefed up online a lot about their midrange, and so a certain extent it is true.

Jun 3's have shown amazing midrange too, with the right setup.

You could sell the ITR valvetrain as easy as you bought it, so that is not a factor to fret over.

I have a quick question. I plan on getting a set of CTR cams. Along with ITR intake/exhaust valvesprings, ITR set of retainers and SSR cam gears.

Is it nessacary to also get ITR intake/exhaust VALVES? I have a b16a2 fyi.

Forget the valves, if you really want them only do the intake side.

I'd put the money you'd use on the valves into your ECU management.

Forget the ITR retainers also. They're the same shit as B16A ones

Would you perhaps know where to buy just the ITR intake springs?

Oh and just to clarify, Is it totally necessary to do an ecu swap and use v-afc when I get cams, or is it just preferred because it can net you a few more horses? (I plan on going to a dyno and having someone else do the tuning.)

If it is needed, where can I snag a V-afc? and where can I get a more in-depth description of it?

^ More tuning capabilities, more power that you will discover or unleash.

ITR Intake Springs? I've been out of the Honda game for over 2 years now. I lost all my contacts, and forgot all my supplies. I have some in Canada, but it won't be much good to you, and you can get them cheaper where you are. Maybe try Len @ Baranco(sp) Acura. Someone is bopund to have his contact on here on Honda-Tech.

VAFC is just a tool used to control Air/Fuel and a few other small things. Save and get a system like a basic Hondata or something similar. There are millions these days. Lots of knockoffs that shops sell under their own labels. They are all pretty much the same unless your looking for wild power.

Anything with a stock bottom end can be tuned to its peak with a basic Hondata and no other tools but a dyno. And cam gears... Can't forget the beloved cam gears

I am using ITR valvetrain w/CTR cams, 9200 redline. CTR cams are designed to reach 9000. The result is alot of high end power on a B16A2. Torqueless? not to bad considering how my motor is set up.

No, I would look into stronger valvetrain for those cams...

I personally am a big fan of supertech's products, so I'd look into them.

i could be wrong but i heard that the better of the set ups is to keep the b16 springs on the intake side and type r intakes on exhaust. now i no this sounds wrong but i was told that the b16 springs are stronger because the valves are heavyer. which would make sense. the problem lies on the exhaust side because the are just single spring set up. working at honda dealership i have personaly seen just the exhaust valves bent when some floated the valves.(overreved)

Please give me a hand on this.

I'm using itr valvetrain on my b16a, and I'm stuck with choosing a cam. Basically, my question is whether Toda B & Jun 3 cam are ok to running with itr valvetrain? Let say if I keep it under 8800rpm.
