high Rpm cams for KaE
high Rpm cams for KaE
wondering of some companies that make a high rpm cam for the ka sohc engine that will increase rpm. i also plan a valve train upgrade and would like to know where i could get a bunch of parts like retainers, springs, and rocker arms because realnissan.com has closed.

well, so your looking for a full race cam? or daily drivable (especially in a truck) slightly milder cam? Either way, i would say pdm-racing.com has you covered. Im not associated with them in anyway just had good experience with their camshafts. The c404h works well with stock valvetrain components, the full race cam does not. If you looking for an all out race cam for ka24e, you wanting to be around ~300degrees duration, .500" lift for both intake and exhaust. This will allow the ka, with stock bore and stroke, to breathe decently above 7000rpm. This type of cam will also require stiff valve springs, and the stock hydro lifters could not handle it, so solid lifter conversion as well.
Im not 100% sure as to where to buy stiff valve springs to suit ka24e. Contact pdm and ask what they recommend for thier race cam. TulsaTurbo.com, and I both sell solid lifter conversion for ka24e, you can make your own, or find somewhere else to get them. I can get stiff valve springs and upgraded retainers for ka24e exhaust only.
You want this sort of engine in your 4x4 truck? you will be losing massive amounts of low end grunt. I would run a much more mild cam myself, and stick with the rest of the stock valve train components. You can upgrade to the 240sx cam for some higher end hp, or one of the milder pdm grinds. This would work well imho and save a lot of money in the headwork.

yeah i still do wanna keep as much low end torque as i can but i want the fun high rpms too. thats y i was looking at the pdm c404h. i was just wondering some specs like what it can rev too with stock valvetrain. I also wanted to buy a turbo later and dont want much overlap. ideas for that? thanks for the info.

The c404h pulls very hard all the way up to the stock 240sx redline. I think a rev limiter set 300-500rpms more would suit the cam well. This is with all stock valvetrain components, including hydraulic lifters. I would recommend solid lifters but its not necessary if your hydros are in good condition. Compared to the 240sx ka24e stock cam, in a 240sx, very little low end loss is noticed.
This cam is not super wild on the duration, so i see no reason why this wouldnt be good for turbo ka24e as well.
