86-87 nissan pulsar had the ca16de. if you're planning putting the cams in, you only need the intake cam. if you can a hold of both then get the exhaust cam as well.

Hi,

The ca16de cams only came in 1987 nissan pulsar, I installed both the intake and the exhaust last weekend, but I didn't notice any horse power increase at any power band, also before I installed them, I measured the duration on both the ca16de and the ca18det, and they both measured the same. So, in my personal opinion they are both the same.

Let me know what do you guys think.

Thank you,

Pulsar GTR

same grind, it's a rumor. This is confirmed by my micrometer and an article in Option magazine about such street myths. No cheap cam swaps for the CA, sorry.

It's not the cam height(valve lift) that's different, its the valve timing: CA18DET 248degree- CA16DE 254degree(or 256 can't remember exactly, looked it up along time ago)But i don't know if there are any powergains, although it opens the valves a few degrees longer (maybe with variable cam gears you can play a little with overlapping).

well the Silvia CA18DE at least has the same cam on the intake and a shorter duration on the exhuast side, no good. Not sure about the stateside 200SX ones

the stock turbo cams do pretty good pushing the S14 turbo on my wife's car. I mean how much power do you want?

i want about 400 RWHP and to do the 1/4 mile in 12 seconds or less, be able to spin the tires shifting to 3rd and smoke the local evolutions, subaru sti's and all the turbo honduh's...

but at the same time turn down the boost and let my mom use my car when i take her Peugot 307 to the beach to surf on weekends etc.

i just picked up an imported australian mag at my local book store. its called ZOOM force-fed performance. there is an article on a ca18det powered silvia. the article states as follows:

"The all-important camshafts are a mix of original on the exhaust side and a ca16de item acting directly on the inlet vavles. The naturally aspirated ca16de cam offers a max lift of 8.5mm and duration of 248 degrees compared to the ca18det's 7.8mm and 240 degrees."

just thought id stir up this "myth" a little more. it seems to work for him. id suggesting looking for this mag if you like interesting turbo cars. there is an old *** australian excort with a crazy engine setup. its got a mx-6/probe 4 cyl turbo motor setup up north/south for rwd, its got a dohc cosworth head, the original intake manifold with a volvo throttle body, a custom turbo setup, and the engine management is a modified factory ca18det ecu. strange.

well the CA18DET exhuast cam is a 256 with 8.5mm and this is straight out of the Nissan FSM. Seems like twin exhuast cams would work best.

I tried that, it worked allright but was a pain to get the thing degree'd in correctly since the dowel pins are different. I eventually went back to my CA18DE intake cam.

there are good gains to be had using adjustable cams gear on the dyno also to increase torque. the de cams are interesting I thnk there would Have slight gains but it wouldn't justify doing the swap unless you are complately bored :).nice to read some CA talk It hard to find . Ihave my gtr injeoctrs and rb20 afm wait ing for my ca lookign at fittig an custom manifold with a t3 from an rb25 I'll let you guy know how it goes.

Why not the S14 turbine, it bolts right on, no custom manifold needed. The RB25 seems a little large on the hot side for a CA, response can't be very good.
