well i've been seeing alot of buddy club posts lately and was thinking about getting the st. 4's but my motor is a b16a2 what is the recomended compression for those cams??? would ctr pistons, 2 layer gasket and p&p polish do the job? looking for around 175-180 whp in my b16.

11:1 CR *MINIMUM*. the more you go over that the more power you are going to make. however, unless you have some internal work done, I suggest you stick with the stage 3s. they will be more then fine for a B16A2 unless, of coure, you are running crazy compression and feel the need to redline at or above 9K RPMs. Either way, remember to change out yor valvetrain. Omnipower valve springs and titanium retainers are what I went with, they are a good bet. As far as getting a higher CR, a mugen (or the like) thinner head gasket will net you ~ .4 points higher, and upgrading the valves to some with a "flat head" are good to bump it up even more. Remember, a stock B16A2 is stuck at 10.2:1 so you have a ways to go before these cams will b e worth while for you.

 

cool thanks man. you think it'll yield around 175-180 whp tho??? with the pistons and bc3+ or 4 plan to take to like 8.5 rpms. and head work.

 

if ou are able to achieve at least 11:1 C I could see 175WHP out of it.

Im shooting for 200WHP my self. see my bio for mods and (near) future plans.

 

200 whp and into the 13's i think you would be in the 12's with slicks. and maybe 13 with street slicks. my buddy hits like a 12.8 with 198 whp.

 

not with a 2600lb EM1 Im not.

 

alright guys help beezer out

would u
1- mill .040+run a 2 layer headgasket
and buy buddy club3+(11.8-1 ?)
or
2- run ptc s and a 2 layer headgasket with ctr cams-(11.6-1 compression?)

 

alittle help here guys

 

im not a big fan of milling the head. I know people do it all the time w/o problems, but its just throws everything that much more out of wack as far as what honda intended.. you know the valves are THAT much closer to the pistons. The headgasket, and pistons would be a great way to go, or di I im doing, and get the headgasket and some flat head vlaves. thats good for almost a .8 increase!

so a 11.1 cr minimun...should i go with the bc 4 or bc 3+...i'm not planning to get a crazy build...all i have is stock jdm itr with i/h/e and a apexi power-fc...

 

so a if i run a milled head to like 40 and a 2 layer gasket i will be ok for the bc4's or should i just run the 3's??

 

anyone think buddy 4s r too big on a b16 at 11.8-1 compression?

 

that should be fine. if you are closer to 11:1 id go with the 3+.

 

I have a B16 with .30 off the head and flat bottom valves. I run a oem head gasket and the BC3+s. Stock block. Having never dynoed my car, I can not tell you whether it makes 175, but I can tell you that where I come from midrange is what matters and for a B16 car, mine has a good amount.

The bottom line is that BC3s IMO are pretty good cams for a B16 from all the cars that I have driven. It is entirely possible to over cam a motor so that is something to think about when considering the 4's. It is one thing for the 4's to make great power on a 12.5:1 2L car, but whether it will work on a low compression B16 is another story. Alot of guys on here have been saying that 11:1 is enough to run the 4's but I think that is less than ideal.

The power band that you have specified of 8.5K does not really optimize the 4's either. That is the area that the 3's start to level off. So unless you want to change some of your parameters, then I suggest the 3+'s. My .02.
