Yep, B16A retainers = EK9 = every other Bseries vtec motor (im fairly sure). Have you searched on Honda-Tech? Heaps and heaps of info about CTR cams in a b16a and other issues surrounding it.
CTR cam’s work very nicely in the b16 engine you will find plenty of people running them, typically on a b16 engine with STOCK retainers and upgraded valve springs using CTR cams the rev limit is set to 9000rpm, these cams make power very nicely up to 8600rpm then drop off power.
Stock retainers are good for 10,000rpm over 10,000rpm and you should look at replacing them to lighten the valve train. Professional tuning is the key.
The stock bottom end should hold up with no problems with 9000rpm assuming everything is in good order, but I can’t comment on your setup as iv never seen it. If something isn’t perfect, it will break, and it will cause catastrophic damage at any engine RPM. Remember the b16 engine has a very good rod stroke ratio so it likes to rev. having said that though just reving the engine harder doesn’t make power unless its tuned correctly by a professional.
Meh as for Chics there always around thats part of racing girls n car's always go hand in hand ill tune the girls just as hard as i tune the cars...
Ghost,
be very careful of internet mech's & self proclaimed professionals.
I wouldn't be operating a B16A into the realm of the B16B (9000rpm) regardless of camming for a variety of reasons.
a) 7mm extra rod length of the B16B, gives around a 1.8r/s ratio compared to 1.74 of a stock b16a.
Have you ever seen the B16B rods, they are designed to reduce reciprocating mass. They are VERY different to the stock B16A rod!
b) Stock rod bolts & Stock Rods at that operating rpm range - Material stretch & quench clearance issues start to become a factor.
c) B16B crankshaft although displaces the same volume, is different in design & finish to the B16A.
I wouldn't go past about 8500rpm with a B series with the std rods, upgrade your rod bolts and all will be ok.. when upgrading your valvetrain upgrade all the parts.. I have seen plenty of retainers break and cause alot of damage..
