Okay, so im working on a built LS-Vtec for my 93 integra, and ive gotten to the fun part of getting a list together of all the things my paycheck is going to be spent on in the following months. My main concern is the cams though. Im trying to go as big and wild of a grind as possible, while still being an off the shelf part that will be easy to obtain if i ever need to in the future. So far, the cams ive kinda set myself on are the Kelford 176-R1 cams.

these have the highest lift, but compared to some of the TODA cams, not so long of a duration. and to my understanding (which could very well be completely and utterly wrong), the shorter the duration, the more low end power/torque you have, but you lose out on the top end when compared to higher duration cams. Long story short, this cam looks like its exactly what i want. What kind of head modifications would be required? valvetrain obviously, i was planning ferrea valves, springs, retainers, seals, etc. Is there a better brand i should use? I also noticed that ferrea sells their own rocker arms for b-series vtec motors, would it be a worthwhile investment considering the setup im planning? thanks for the help guys

 

I can tell you right now man, those are way too much for you. If you don't have more than 13:0 compression and at least 84mm bore that cam is not gonna work for you. And just because a cam has a lot of lift doesn't mean it will give you alot of power. There are better choices out there man. Lookin at the open and closing specs those cams, you better have some displacement to get them to be effective. What kinda powerband and power you looking for?

 

im looking at a more mid-range power band, and id like to be as "streetable" as possible while still on pump gas. Maybe i overshot lol

 

What's your setup gonna be?

 

right now, its going to be 82mm Ross Racin 11.5:1 pistons, forged rods, and a rebuilt/cleaned b16 head. Once i have that (because the car is my dd and i cant really afford any down time) im taking my old block, a b18a1, getting darton sleeves and boring it out to 84mm probably between 12 and 12.5:1 comp, and building the head. its an LS-V btw.

 

Ok well with that being said, go with the 176-c you are going to run kelford cams. Also recommend the edelbrock performer x manifold since you are a 1.8 liter. What are the other mods as far as exhaust, cam gears etc?

 

With The 84MM Bore, Ill Be At 2 Liters. IDont Plan On Building The Head Until I Sleeve And Bore The Block. I'm On My Phone, Sorry ForThe **** Typing

 

So you're building for a 84mm setup? Where do you want your power at? What exactly is this motor for, daily or straight race?

 

its going to be for an autocross car, and im shooting for 250ish after all is said and done. its not like im dead set on the kelford brand, but ive heard alot of good things about them. a buddy of mine is running skunk2 pro2's and vtec doesnt really snap, which i dont really like. im looking for the most radical cam i can. ill admit id like to have one that keeps the kick of vtec and has a lope lol

 

LOL. Okay then. If you really must stay with kelford cams, then go with the 176-c with the built block. But some cams aren't meant to have a pop or a snap and technically that's from a poor transition to vtec. But you can get that snap or pop even with pro 2's, it's in the tune though. If you want 250 maybe you can check out m24xx cams products 2 or maybe pro 3 cams. I'd advise you have some headwork and ported manifold. For autocross, you don't always need peak power but a setup that has some bottom end tq and response. You have to be careful, you could overcam your setup and the setup will run like boo boo if it is. IMO, look for a cam that has quick response outta vtec. I use the open and closing events to help me out with that.

Check out this video of kelford 176 c's since you like lope lolhttp://www.youtube.com/watch?v=-gox4Ui0tJo

 

i cant find anything on the m24xx cams, but i have looked into the pro3 cams (from skunk2 im assuming)

 

Are you doing any head work? What kind of intake manifold, exhaust, and header are you planning to use? I'm gonna be using m24xx on my 12:5:1 compression 84.5mm setup with slightly ported head. Could you throw all of the details if the entire engine setup on here?

 

like i said, because its my DD, im dropping in an ls-v with 82mm 11.5:1 comp pistons, forged rods, arp bolts (main, head, and rod) with a rebuilt b16 head. After i get that running, ill be buying parts. After all is said and done, im hoping for 84mm 12-12.5:1 comp, forged rods, arp bolts, and a fully built head with ferrea valves/springs/retainers 1mm oversized. the only thing left i really need to get figured out is the cams

 

For the daily setup just go with kelford176-c cams

 

cool, thanks for the insight

 

No problem man
