hey, I was wondering if anybody has a set of 63402/03 vtec cams. I want to know what you think of them. Has anyone had a camshaft break? If so, what kind of valve spring?

 

i've got a set of 63402's right now, and the car is having idle probs, but i was able to drive it for a 120 mile trip, and ran perfect. i'll let you know how it performs after everything is worked out. a friend had the same setup about a year ago or so. Crower 63402 w/ all recommended crower valve train. in a 00si w/ 65 shot nitrous he hit 13.8... he used the car for daily driver too. has a mild idle to it, but nothing radical.

 

well i just put in crower cam in my b16 first gen and i had some probs with idle too
my car wasnt idling enough so i had to turn idle up alittle and now it is fine
and man it is great when u hit vtec

 

dam slow *** crxs......jk brett

 

what motor are they in????? i dont mind about the idle, I know to make it run decent. I have seen one pair break.....Very unfortunate just checking on it w/ others. So far so good

 

well mine are in a first gen b16 and yeah i have read about them breaking too but u cant hit 10000 rpm they will break.. just make sure everying it installed proper and u should be alright.
man i love the vtec cams now i just need a clutch...booo

 

My buddy has the 63402 on his gsr and now he is considering changing cams because he feels the cams are not producing that much power.

Just some additional info for you...

 

I had the 03's in my 1st gen B16a. They had crazy top end, and a good bit of bottom end torque. But I took them out for CTR's. Now I sold my CTR's and I'm doing ZEX 59300's....

 

Some info on cam breakage...

I used them in a 1 gen B16 and they worked good for me. I ran a 14.2 with stock exhaust and intake manifolds, TB, air box etc. I tuned them with a hondata pr3 and cam gears.

 

we ran 12.3 with these cams b20 vtec hatch
