i have a question, i have an ls/vtec with the folloiwng

the head is b16 with ITR valve spring and retiners
buddy club spec III cams
str cam gears
dc jdm 4-1 2.5 header
holy fpr
aem fuel rail
aem short ram
RC 270 injecters
es ovel muffler 2.5
VFAC
low cash ecu
integra rear disc
walbro 255 fuel pump
the head has a 5angel valve job port and poilsh
and shaved .30, and ARP head studes and cosmic head gasket

my question is i just installed the cams and was wandering if anyone has something along the line as this and if so what they had there vtec set at and there cam gears because right now the cams arent really doing much because the cam gears and vtec are i was told way off. but i dont know how they knew that but not how to fix it, but i am just trying to get half way close to right before i get it dyno tuned. thanks

 

why not ask the guy u bought the cams from

 

Leave the cam gears at 0 deg until you put the car in the dyno.
Concerning vtec engagement, agressive cams such as BC's like higher vtec engagement around 5500-5900 rpms depending on the setup.
I would set vtec engagment at 5600 rpms until you put it on the dyno.

 

Well I will say that every setup is different and the bore plays a part in it too. I know on the cars that I have tuned NA with the IIIs or IVs, the vtec has always been around 5000-5150. I could tell you the cam gear settings, but that would just be too much info for this tech forum.

 

I was reffering to my experience with sk2 stg2s on 81mm bore. I have yet to even see a car in person w/ BC cams.

I personally would run a 5600 rpm engagement & stay out of vtec until I put the car on the rollers y0

 

i really wouldnt worry about either. whoever tunes your car will take car of both.

 

I would personally upgrade to something better then the ITR valve train.

buddy club says that the spec3's can be run on stock b16 valvetrain. he should be fine w/ the itr's. bc3 are close to skunk2 stg1's in the lift department but have more duration.
