i know this subject been brought up before but i couldnt find anything

was wondering if i can run the itr cams on a stock b16 valvetrain??

if not can i get some details?

 

ttt for some info

 

I stated before that you could but was quickly corrected. It would be unsafe to do so. If you're going to upgrade cams, upgrade valvetrain

 

keep it within the stock b16 rev limit and you should be fine

 

under 8500??

 

DING DING DING DING DING DING

Dont cheap out on valvetrain...your interference motor will thank you

 

Cant be said any better.

 

That is exactly what I said. Someone posted the a picture with the differences between the different valve springs. Explained how the b16 springs are more prone to binding and so on. If you can't afford aftermarket, find some used ITR springs

 

b16 redline is not 8500rpm, im running 00 ITR cams on my stock gsr valvetrain for a year and a half now, i havent had any problems so far

 

is b16 valvetrain different from gsr's??

i thought that was the redline, guess i wont pass 8200rpm then

 

not familiar with b16 valvetrain but if you do put them in keep it in 8100rpm. i take mine to 8500rpm i guess its jsut my luck according to everyone, yet i wasnt the first to run itr cams with a stock valvetrain

 

i c haha, cool

imma put them in and stay under 8200rpm or so


thanks to all that gave me info

 

you will be safe with them just dont rev over the b16 rev limit. i got 2001 itr cams on my b16 and got it tuned on crome redlining at 8,300 and my motor is still fine. have it for 6 months now.

 

So, with bigger cams you just need to not exceed the stock rev limit and you're ok.

 

^^, doh* with itr cams you MIGHT be fine, but to be safe you might atleast need itr valvetrain.


or just run it to see what happens

 

i just ran it around for 2 days but didnt past 8k so i guess its ok

 

gsr intake side is the same as older itr intake. some people run gsr on both ex and in. they are dual springs. i also had a friend run ctrs on stock springs and didn't have a problem. Just dont miss shift.

 

Thats not whats being said here. Its been stated that with ITR cams, one would be ok with the stock springs if the rev limiter was kept to the stock point... of which I would agree... now if you wanted to run something like say stage one cams, I would say you would need the ITR springs. If you wanted stage 2's or greater then its time to look into aftermarket springs.

 

Lol, so what limits spring usage, lift or rev limit?

Also, have any of you looked up MOTU spring test?

 

Both. Since you are limited by both coil bind and the springs ability to keep up at higher rpm(valve float)...

And PLEASE don't tell me you are one of Rockets old minions. He can do all the "tests" he wants. The guy might know a thing or two but I would take it with three grains of salt and then still research the hell out of it before I believe anything more from his mouth. The stock B16A intake springs are the SAME as the ITR springs. Move them to the exhaust side on the B16 and get the ITR intakes if it really worries you. He can test all he wants, people have run these cams on stock valvetrain for years without issue.

 

lol i ran Itr cams in my b16 and reved it passed 10,000 plenty of times and had no problems at all.

motor finally popped when i ran alot of nitrous threw it :D

 

Wrong, you do not know how to design a spring. If you did, you would know lift is the controlling factor.
Further, itr and b16 are not the same springs. Again, you need to look up the data and the parts.

 

i dont even think ITR cams make power to 10k.LOL

 

But does that really matter it rev's to 10K that is more important.

 

how is it important? obviously he wasnt running a stock valvetrain
