So I have been reading a lot about set-ups similar to what my set-up is planned to be:


Head:
b16 head(decked .002 and pnp'd)
Supertech valves(1mm o.s. on the intake and exhaust)
Supertech guides, springs, and retainers
Bisimoto Cams(pre-owned, made tons of power to 12k on buddy's boost set-up)
Custom breather box

Block:
B20b (no decking or anything)
Eagle rods
King race bearings
RS Machines 12/1 pistons
Custom breather box

Tranny:
SC-4
Exedy hd pressure plate
Fidanza 7lb. flywheel



Now my question is:
Are these cams too big? They were made for a "near race" motor. Bisi wanted them to make my buddy's car scream as an all motor. Then he went boost and bent a valve. I don't have the spec card on the cams, but I know they are a nasty all motor cam. All I've been able to see, is people claying their motor. If that is what I have to do, then that is what I'll do, but would like to have a bit of "educated" foresight. Thanks in advance!

 

Are you referring to the ITR RS rep. pistons in your build? If so P2V clearances should not be an issue beings the block is not decked and the milling on the head isn't enough to make a difference.

If it were my build Pro 1's or 2's would be my cam choice. Or some RM24's
Tuning and cam degreeing is key.

 

I just saw a set of pistons on ebay that said the c/r would be in the neigborhood of 12.0/1. I want something that is a bit more aggresive than the pro 2's, as this will be more of a fun car than a commuter. I will be getting the tuning done in Salt Lake City by Jasen Penmen. So tuning and cam degreeing will not be a problem.

 

give bisi a call and see what he haves to say

 

Do you have any idea how hard it is to actually talk to Bisi? I wasn't able to get him on the phone. Is there a magical phrase?

 

And the reatarded post of the day goes to...


And its VTEC not VTECH
Lol

 

I've yet to see a b series cam from bisi perform..boosted vs na apps are different 12k? full of **** i think so.

Your setup would love pro1's or pro2's.

 

get the specs from Bisi or else you can degree them and find their lift/duration, opening/closing events so you have an idea of how big they are. Usually piston to valve clearance isn't an issue with minimal material being taken off. You should pay close attention to valve-to-valve clearance though being that you are running both oversize on the intake/exhaust valves.

Another note, if they have over 260* duration then most likely they are going to making power in the higher revs and will be considered a big cam.

 

some how i talked to him several times. i really didn't expect it, but i guess i caught him at the right time.

 

that block with a stock head, pro1 cams

 

This just tipped the scale. Im done with this site for the rest of tonight, maybe even the weekend. UNREAL the people that are on this forum now.

 

^^LOL i agree

 

If id never heard that before, it would be funny. Seeing as how you are probably the least original person on the forum, you can get f***ed buddy! If you have no info(which you don't) shut it down.

 

Ill upload the vid as soon as I can get it onto my computer. This isn't a debate, just asking as this is my first n/a build. Need a bit of info, from THOSE WHO KNOW! Thanks for the bump though.

The comment wasn't made to make you laugh, its quite sad the amount of people who don't actually know what vtec is

Try and make all the insults you want...just remember who the dummy is that posted this thread.

 

Do you have any information to contribute to this thread? If not shut up. Thank you.

 

You answered your question in your op

Clay it

Your not gonna get the same power gains without major headwork tho

 

I contributed..

People pay me to go fast bro. Not the other way around. I gave you your answer..and i question a cam making power to 12k, specially on a boosted setup.

 

I was gonna call bullshit on that as well, but I'm not the type to speak when I m not sure

Especially using NA cams on boost at 12k

 

Again, this is not a debate thread. If it were I would have uploaded the video before the statement so I didn't have to hear this horsesh*t. I just have a hard time beliving that a custom Bisi cam won't make more power than a mass poduced S2 P2. And that was not the question here either. The question was to see if there was, by chance, anyone who had run a B20-Vtec set-ups with a large cam. Furthermore to see if said people had any idea about what the p-v clearences might be. Please only constructive input from now on.

 

I have a b20vtec with pro2's. Had pro1's also

About to have my custom grinded cam in it soon.

 

Hahaha I just realized why you made this thread

If you had actually read what I said in the other guys thread I said specificlly that you could not use bigger cams then itrs without CHANGING THE PISTONS

Your swapping your pistons, you'll be fine

Pull your head out your *** and read EVERYTHING and you might learn something

 

It's people like you that make this site less and less enjoyable. Obviously YOU didn't read the entire post, or else you could have got your power thrusting out 3 posts ago, and we'd be done with this. I bet you get slapped around and your *** kicked a lot huh?

 

your a moron, plain and simple, don't try and profile me cause your head is shoved too far up your *** to comprehend a post



Just keep in mind who's username contains "vtech", and no it never gets old for the rest of us
