Crank angle sensor options

I've search here and the tech section but can't find the answer.

Is there a crank angle upgrade for pre 1993 z32 to a more reliable unit? ie: like the S2 PTU install, can a later model crank angle sensor be used in a 1990 model zed?

 

Aftermarket ecu and crank trigger. Pretty much the best way to do it.

 

can you elaborate on this for us all?

 

*waits for mungy to chime in*

 

Yes it can. You'll need to upgrade the CAS connector on your engine harness to suit the later model CAS.

 

Thanks I was hoping that's the case.
Is there a tutorial or wiring diagram?

 

Not a fan of aftermarket ecu options. They cost as much as a zed (then you need them tuned), and why bother when the factory ecu is so easily tuned? Only benefit I can see is launch control and other stuff I'd never use.

It should also be said there is bugger all reason to do so.

In fact it could be considered a backward step, say you are diagnosing a problem and you wish to swap out the CAS, plenty of early ones around very few latter ones.

 

I got the impression the newer unit were more reliable?

Last time I had a problem I went through a handful of old CAS' before I found one that works. And then I wasn't sure if it was working correctly.

I don't find newer ones that hard to find, if anything they're easier as it's hard to find an old one that actually works! Again, I'm going on the assumptions newer ones are more reliable.

 

I guess newer ones are more reliable like clean air filters (new) improve HP.

People tend to not throw dead pens in the bin so picking up several in a row that do not work can happen.

But if yours is dead and you can find plenty of latter ones why not.

 

are they really that unreliable? mine seems to still be on the original cas and connector

 

series 1 or series 2 doesn't matter if they are new .

I bought a new series 1 CAS and TPS just to make sure they are working at 100%.

they went from Mitsubishi to hitachi .. whether it was a better deal for Nissan or they are actually better in some way ? who knows


.

 

No I would say they are very reliable, being optical and all.

 

My friend has gone through a couple recently so I'm just trying to future proof myself without forking pout for a new one.

 

some early cars were known to chew them out due to poor alignment. The machining wasnt quite right. only applies to 89 models i think though, maybe some 90 cars.

 

Hmm, do you know if the problem was at the cam or the shaft on the sensor itself?

 

I believe it was to do with the way the head was machined. Either the exhaust cam tunnell or where the cas bracket was drilled and dowelled

 

CAS was OK it was the cam locating dowel that failed.
