300zx Z32 Cams
I heard a rumor that that the Z32 cams are a direct replacement for ours but they have more lift. If this is true has anyone done this switch. I am afraid of running valves into pistons with the increased lift.

That kinda sucks I know where to get cams from a wrecked twin turbo 300zx. Thanx any way man.

Nothing but the 8 hours needed to replace the cams and chance at screwing up if you miss align the chains/sprockets.

You have nothing to lose by trying. Why don't you get a baseline dyno done and then swap cams?

Ok guys hers the plan for the engine. I have a turbo waiting but I also want to build the motor up. I just want to know if i can get some Aftermarket cams for a z32 and have them fit. If they do I dont have to get aftermarket cams built for my special application.

it takes a lot of modification to get the z cams to function right. i had over 15 hours in dyno time alone {so im a dyno *****}id talk to JWT about camming a ve and see what they say. i already know the answer
the vg max's are sohc motors, always have been

Err....
Well we got a dyno here. But the problem is do I wanna go through all that trouble. Probably not. I think with the setup I have instore then I wont need these cams. It would be nice if they were a direct change over.

Re: Err....
Here is the easy solution order new billet cams from nissan. There are going to be expensive since you have to order 4 of them and they should retail around $175-225 each cam. After you receive these cams contact a camshaft company (Crower, ISKY, peaco, Web, Schnider) and give them all the info on the stock cams and supply a dyno chart, so they can know how the powerband looks like. After that you tell them how much of a lopey idle you can tolerate and where you want the powerband to be shifted too. If your going with a turbo motor I figure a 260* duration grind would be a good bet. Turbo SR20DEs and VG30Es have good results from those type of turbo cams.

I wouldnt take stock cams out of a car and get them reground I had this idea already, the problem with that is that you cant get the lift to change or the center line, You can only change the duration.
What I need to do is get the specs off of a z32 or a SR20DE and order a custom made forged cam set but that runs somewhere between 1500 and 2000. So i guess I am at a standstill where I need to modify the internals to be optimized for the pre-existing cams. I am ok with this as I was planning using the stock cams anyway. I can always modify the valves instead.
If you guys have any other ideas I will take that.

i used n/a cams. they are no means a direct swap. a mechanic buddy of mine spent 3 days working on them to get them to sit right and the car to run {nissan tech for 30 something years}
then dyno time, messing with spark plug combo's, fuel pressure, timing in general, different types of fuel
for the little bit of hp i gained, its not worth the money.

Also before you started messing with plugs, fuel pressure and timing how did the engine run, any idling or driveability problems?

VE's don't like big cams, stillen and jwt will tell you this first off.
and as far as thwta all went into the install. im not 100% positive because i didn't do it, and i didn't watch. it was also done over 6 years ago as well.
im doing the best i can here bear with me
