i have a b20 vtec (b16 head) ive had it for 3 years im just wondering how i can find out what type of cams i have. im thinking they might be ctr or itr but i dont know, all i know is it pulls so much harder when vtec kicks in then any of my other friends with stock setups and its very loud?

this might not sound like i know what im talking about, but id just like too know if theres any kinda marking on them??

EDIT: my ls vtec w/ a gsr head didnt even sound or pull half as much as this does neither does my brothers b16

 

pull em out and see

 

if u havent changed the cams in the head and the head came off astock car then it is probably b16 cams

 

my heads a sir1 1990 b16 head (jdm) and ive pulled my cams manys times im just wondering if theres any marks on them im sure somebody in the last 15 year could thrown some itr or ctr cams in their.

Searching is usually the quickest way to find an answer to a question like that.

Also, I do not believe that it is the cams that determine the audibility of your VTEC engagement. Unless I am mistaken, it has to do with timing and intake manifold design.

My B16 sounds like a second engine coming on when VTEC engages. REAL friggin' loud.

And that bump in torque you feel when VTEC engages is usually a sign of a mis-placed VTEC engagement point. When tuned properly, there should be a smooth transition torque-wise from the primary lobe to the VTEC lobe.

I heard the guy with the loudest vtec always wins the race.

lmao.

i think ctr cams have a louder "crack" when they cross over. but thats my oppinion.

 

edit wrong thread

 

anybody else read that he has a b20/vtec? of course a 2.0 is gonna pull better then a 1.8, torque owns joooo

 

my ITR cams are way louder than my b16 cams were.

 

type r cams have a very loud cross over riding in my friends ctr hatch the ***** very loud compared to my skunk2 stage2. the cross over anyway lol i just walk past him.

 

a lto also depends on the ecu and tuning you have done.
i can make ANY engine with vtec have a very loud and noticeable changeover if i set vtec too high.

 

this is true my friend got a kenji chiped ecu and the cross over got even louder. in vtec you cant hear **** inside the car.
the vtec was lowered to 5700

Werd. I've gotten people who've commented that they could hear me going up and down the highway from 1/4 mile away. Putting a CAI or shortram on a B16a makes vtec engagement unbelievably loud.

 

they might be type r, my friand has the same setup and his cross over is loud<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by drobinson &raquo;</TD></TR><TR><TD CLASS="quote">My B16 sounds like a second engine coming on when VTEC engages.

sounds like your vtec engagement is just later than other peoples, not really a good thing, your exhaust might be different as well.
