Some of you will frown at this, but I'm looking to make a torquey all motor H23, and next step is cams. Just a little confused about the stages. Are stage one cams specifically for turbo applications? or is there a stage I cam for turbo and one for n/a?? And if not, if I pop some stage II's in do i have to upgrade my valvetrain? Are stage II's good for n/a applications? I need to be pointed in the right direction . Brand, power, the whole dealy. I realize the answer is prob buried deep in the FAQ section somewhere, but I just could scan through anymore threads about lift and duration.

 

Stages mean nothing.

Real cam specifications mean more. Anything greater than 200˚ duration at .050" lift and much more than .425" total lift is getting into the realm of an aggressive cam for the H23 IMO. By the time you get up around that duration you end up having issues passing emissions and have a lope to the idle that gets difficult to tune on the low end and part throttle.

You need to determine what your goals are. You can have a peaky power band but then if you intend to street it it'll be a dog around town. If you want a middle of the road cam then you can keep some of the low end performance but sacrifice some top end.

On the H23 you'll have to upgrade the valvetrain if the cams go over .375" lift or you'll run the retainer into the valve seal.

Not a lot of people have built H23s so you're not going to get a lot of feedback. I've run Crowers and the do pretty well considering the small amount of money I have in my build.

You may want to look into GUDE also.....They were big with SOHC Non VTECs back in the day.

 

Not too worried about emissions, we dont have checkpoints here or anything like that. And I am looking for a daily driver motor that makes more torque than power really,

 

I agree with gude they seem to make some impressive h series sttuff

Then don't ever rev past 5252 rpm, either that or or get a diesel.

Yeah, everyone can have more torque than HP if you keep the RPMs low enough

 

Lol..kinda set myself up for that i guess. But seriously, with some stage I non turbo cams on and h23 with a exhaust, header, intake, s100 and a good tune, could this be ok? Mainly looking at stage I's just so i dont have to go out of my budget by upgrading the valvetrain. I'll look into the gude cams too.

 

After you spend all that I think that if you blow the money on a "stage one" cam you will probably be disappointed. The H23 is not a bad engine but camshafts really do make a mediocre engine shine. If you go with small cams then you're likely to still have a mediocre engine. If I was going to spend the money on building an H23 at all I'd spring for some cams at about 200˚ and at least .400" lift. I wouldn't go much bigger without raising the compression more.

Also I'm not a big proponent of Hondata but the S100 is a ripoff. At least with the S300 you can retune if you ever decide to change camshafts or mod anything else.

 

with a 200 degree (couldnt figure out the lil symbol) and .400'' lift, would that denote a valvetrain upgrade? Trying to keep this all within a budget here. If it does, can you recommend anything that wouldnt be as disappointing at making low end-mid end power that i won't have to sell a kidney for?

Are there any pistons PirateMcFred that i might be able to swap from another frm sleeved engine to get higher compression with? Like h22 pistons or something? Would this also just be another disappointing venture as i wouldnt have the cams to compliment the higher compression. I'd prob have to choose one or the other.
