i have done a little bit of research on this but all i have really found out is it would be ok to run ctr cams on stock gsr valvetrain as long as you dont rev it out...

i havnt heard anything about using ctr cams in a b16a head with stock valvetrain

will that be ok as long as i dont rev past just say 8200rpm?

 

I ran CTR cams in a stock B16A3 head for over 5 years. Revving out to 8500 sometimes. Never had an issue.

 

Lots of people run single springs without a issue....I however would not.

 

ctr cams- ctr/itr dual valve springs simple as that. imagine how many times those gsr springs have compressed/compressed and lost that spring tension. and now u will ad a bigger cam in there. i wont be surprised if i see a thread in a few weeks by you were you ask " blew my engine need help as to why". supertech valve springs are CHEAP on ebay. get some. and save an engine rebuild from happening.

 

It works fine but I wouldn't do it on a tired valvetrain. It's easier to play it safe than be sorry!

 

This

 

I did it on a 94 Del Sol vtec back in 2001 that had 130,000 miles on it at the time. Just swapped cams up until 175,000 miles over 5 years. I even did open track events in the car like this. Never had a problem. This is from experience.

 

and for retainers. you can get some of those k series "CRmov" retainers for about 45$ shipped for all 16. http://www.acuraoemparts.com/delray/...All&vinsrch=no
The part#14765-PRB-A00 is just $2.32 a piece there

 

Do any of you offering suggestions have experience running CTR cams on stock valve train?

 

Me personally, no. I did it right and got dual springs.

 

lol, that's what I thought.. Carry on

 

I ran 00 ITR cams on a stock gsr head for about 2 years. Took it to 8500rpm numerous times. If you can then upgrade to dual valvesprings for safety. If not then do not exceed the stock rev limit of a b16.

 

I got friends that have run them no issue. Honda did dual springs for a reason and thats good enough for me...(i'm not cheap like my friends lol)

 

Ive been running 00 spec ITR cams (same as CTR cams) on my stock B16 head for a year now revving it to 8500 no problems. Also at the track it sees 9k in the burnout box off the limiter. I have taken it apart and inspected with no unusual wear visible.

 

Why do ITR's and CTR's have dual valvesprings in their heads stock, and b16's and GSR's only have them on the intake side..??

Its very obvious they did that for a reason. Valve floating will occur at some point on worn out springs.. if you're going to buy a set of cams that are a upgrade from what you have, get the proper valvetrain to support them.

ITRS and CTRS both have dual valvesprings on both sides, the exhaust is pretty stout for a oem cam, and there is a reason the b16's and gsr's have single springs on the exhaust.. the cam obviously isn't as stout.

Again, this all comes back to a saying, because you did it, doesn't mean its right for someone else.

 

I ran them for about 40k in my b16. then from 08 to this day in my gsr on stock valvetrain.

 

thanks for all your imput guys, im going to leave it stock for now while i save for supertech valvetrain and probably some pro2s...

i had just found a deal on some ctr's and i was seeing if i could get away with running them on stock valvetrain while i save for pro2s but the way my luck is... im gonna keep it safe rather then sorry...this will be my only car once its running and i have a heavy foot lol...

 

all motor guy is right..

 

I can get you a supertech valvetrain for 300 and i'm selling my pro2's as well.

 

He asked if you can run them on stock b16a valvetrain, the answer is yes. I don't understand this mentality of "Honda did it this way; so should you". If that's the case why are we modifying these motors at all then?

I think if someone (in this case many people) have done it, yes it will work for someone else.

 

i run mine blox a's with stock gsr valvetrain, so pretty much the same thing. I havent had an issue, but if you can get a cheap set of supertechs then go that way

 

edit-realized that the link doesnt work....so just use the part number in theyre search box.

..just because it works doesn't mean you should.

do people build plenty of ebay turbo kits that run fine for a few years? yes. do they run as good as probably built ones? no and not for as long.

if honda thought you'd be fine on single springs they'd put singles in ctrs/itrs. the reason people say this is they're a successful still going car building company. and they'd have to worry about engine failure. hence dual springs. its fine you can ride on singles all day long. its like some people(god knows why) like to build their entire engine from ebay while others use tried and tested parts that are known to work well.

 

Singles are known to work well.

I put 45,000 miles on my motor setup that way. Revving to 8,500 rpm's. A few thousand of those miles were open track days on the road course.

Eh, I'm done trying to defend experience vs reading stuff on the interwebs.

 

o.p take a piece of paper and "cut corners" off lmk what get.
