im wanting to know whats the best cams for stock valvetrain? i know i can upgrade valvetrain for relatively cheap and run bigger cams and make more power but thats not what im interested in. im curious as to whats the best cams for stock valvetrain, not oem cams either, i want something aftermarket. ive heard of skunk2 stage1's are pretty good. thanks in advance

 

Spoon?

 

skunk2 stage 1's wont yield much more power than CTR cams...id do with those or BC3's..keeping stock rev limit of course

 

I wouldnt use anything but CTR or ITR max.

 

BC3+ all the way. Will give you a **** load of midrange.

Honestly I thought the BC3+s sucked on my B16. I mean yeah there's a midrange gain, but once you get up top they don't feel very powerful. Almost like stock cams

I'd just do Skunk2 Stage 1s or Toda A (not sure if those are ok on stock valvetrain though)

 

BC3+ for stock valvetrain.

 

BC3+ for stock ITR valvetrain

Skunk2 Stage1 for anything else

what head gasket?
where can i order 1 online?
if anyone has any info that might help that would be the business </TD></TR></TABLE>

huh? I'm pretty sure you do not need that much compression for the 3+. BC4s yeah. I think you'll be fine with the ITR compression.

are you all talking about pro1 or stage 1

 

regular Stage 1 of course.

Pro 1s are like the regular Stage 2

 

BC3+ is more aggressive on valvetrain then you guys think. duration is in the 250-260 at .050 and lift is over .450 on intake and exhuaust. I checked a set I had mid last year and I remember the numbers wer somewhere in there. Exhaust cam did have more lift on it, but the intake had a lil more duration.

 

I ordered mine from evasivemotorsports.

 

thanks for all the info guys. this will be goin on a b20vtec wit aebs manifold, 68mm tb, pos header, and rs machines pistons. head is mildly ported, and hondata im gasket. also has itr valvetrain. another question is, if i go wit bc3+ will i have to grind the valve reliefs in the psitons? im gonna go wit rs machines itr replica pistons.

 

does rocket make anything comparable to the bc3+? does anyon have dyno charts of b20 vtec wt bc3+ in it? a buddy of mine made 214whp on a b20vtec that was pretty simple wit s2s1 cams and stock valvetrain. so its kinda hard as to what to choose. thanks

 

Yeah RM makes the M20/M21 cam but I don't know if I would run it on the r valvetrain.

No you wont have to grind anything with the rs piston. You will have more than enough clearance.
