cam setup on ka's

[project-D180]

OK, after seeing the dyno sheets, I have a question on the cams. Wouldn't a stouter cam give better numbers? Or, are the hotter cams like the JWT 275 with higher lift and longer duration? Also, is there a reason the KA24DE doesn;t respond to dual pattern set ups, like say a 264/275 for NA?

And WANGAN,:cj:

This thread is educational for those who stay with a decent motor that when in this car has a very nice hp:weight ratio compared to a lot of other cars out there. It staright kills my old 2001 Neon ACR for hp:# and is a lot quicker AND faster on the end(140+ vs the ACR's 132)

dude brought up a good point and wanted to know what you kade guys think and did you ever try this offset cam set up with bc/kelford/crower(bigger cams in general):coolugh: cams??

Never tried offset cams I imagine the main problem people have is degreeing them correclty

Cams are sold in matching pairs for the ka/sr/whatever because the manufacturer expects you to turbo the car. Naturally, the intake side should be bigger than the exhaust side (which is why s14 ka's run a lil smoother than s13) but when you turbo a car you want as easy and as great exhaust flow as you can to spool the turbo. I have a 248/232 setup in my ka and I like it better than the stock 232/248 and the 248/248 setup I had in the car.

far as i know i thought the s14 was 232/232 stock and s13 is 240/248

[project-D180]

can anyone comfirm this?

[josh_schul]

I believe you are correct ... s13 cams are in fact 248 240 and the s14 is 232 232.

koo thanks for the comfirming that..has anyone ever tried kelford cams for the ka or colt triforce cams??

S13: Intake-240
Exhaust-248

S14: Intake-232
Exhaust-232

that's probably because you didn't properly degree the "intake" cam


IMO don't mess with cams until you turbo the car. It doesn't make much difference n/a

i have not messed with cams yet on my n/a but they will make a big diff compared to other bolt ons for an n/a. most cams out there are for turbo set ups jim wolf and pdm racing are the only ones that i know of that make a n/a cam and a turbo cam. there n/a cam looks very nice check it out PDM Racing - Cam Corner (http://www.pdm-racing.com/products/cam_corner.html)

It sounds a bit different.

Powerband shifts up a little.

At one point i wanted 11:1 cr, Itb's/mikuni/solex carbs and crower 3's but that was just for the sake of doing something different. not for all balls out power. I had 232 exhaust 248 intake cam that came with car when i got it. Wasn't too bad. The throttle response below 3k sucked but i think that was a compression issue somewhat. After 3k? Straight fire. Useable power on tap. Not much but plenty for drifting and grabbing some corners. Great for a street car.

Overlap period is what's going to help it draw in air faster by allowing the intake valve to open a bit when the exhaust is still leaving the cylinder.
