Pdm Cams

who has these cams in the ka24de? How long have you had them? Opinion on the product?

[240ondrugs]

I guess nobody has them or has an opinion on them!

Hey! I wanna know about them too! Someone....please? anyone?????

I'm having the Colt 404 specs reground into mine and installed here in a bit... Sucks because I just had the motor rebuilt.I'm not happy with having the cam towers lowered, but If I want the lumpy cam, I gotta spend the lumpy bucks. My machinist quoted me about 400 bucks for everything and he is returning a favor on the labor. Should be worth it.

Ahh, I've been away for a while from these forums, and it's a snowday today, so I have some extra time: I have the PDM Stage II cam regrinds in my KA24DE...I had mine reground, I didn't use their cores. I think it's well worth the $450, especially considering my exhaust cost more than that and gave less power....they are really smooth, streetable street-cams, you only lose a little bit of torque down low, not much at all, like around 2-2.5k, barely noticeable, other than that, the car pulls MUCH harder past 2.5k rpm all the way to the redline. My car wants to rev now, and rev it does, up to the redline in every gear...it adds a good deal of power throughout the whole RPM band, especially at top, but the best thing is that it pulls harder in every gear...PDM quotes 11whp at 6300 RPM...i don't doubt them, i chirped third after installing them (see profile)...I'd love to see how rev-happy my car would be with a crank pulley/better fan...Hope i helped!

It costed You $400 just to get your camshft towers milled. Is this normal, or what has everybody else paid? cause Iwas considering getting a pdm cam for my sohc, but if it cost that much to have them milled, well my broke butt aint paying that.

[S13Ka24e]

EricZ103 are you asking about what RedShred said? Because he said to get the cam towers ground down AND to have the whole cam grounded to his custom specs. The custom regrind would be what costs alot. I don't think that the towers ground down would be alot of money.

[EricZ103]

uh.. ok. I must have read the post the wrong way. I didn't think it would cost much to have your cam towers milled, I was just making sure I read that post wrong, I guess. I got sohc so its cheaper for me.:ylsuper . not that i wouldn't rather have a de.

[MarkEmark]

yes, it's a completely new grind from the base circle to the specs of the stage II one...I imagine the SOHC is cheaper (just go to pdm-racing.com and check it out)....the regrind was only $325...it was the $8 per custom shim that killed me (damn 16 valve DOHC's....)

Mark how choppy is the idle?

[MarkEmark]

The idle is surprisingly smooth...very smooth in fact...I couldn't notice but a very small difference in the idling of the car after I put the reground cams in...

[I am Technoman]

Yea my motorsport cams don’t have a very choppy idle. But if I let it idle for a wile. I can here a "fast" chop it kind of sounds like a helicopter from far away. I run open ehxaust maybe thats why....

[bmxruler4130]

325 thats not to bad. i heard you could run an altima intake and a 91 exhaust?? because the duration is higher.... anybody try it?

[MarkEmark]

the altima cam swap is a complete lie...it can't be done....It's $325 + $128 for the shims...that's $453...no cheap modification..

The Altima cam swap can be done but you will gain nothing.Nissan gave the 99 altima 5 extra HP from changing the intake cam But I dont know what the degree is or the duration. I say use two ehxaust cams from a 91 240 only.
