There are points. your right they do look a little warn.
And yes i am going to autocross this car.

We just pulled the rest of the harness and other crap out and spit shined the engine bay. getting ready to sand and paint in the next couple of days.

yeah, the "got pissed at the FI setup" was my guess too! Especially from how ghetto-fabbed some of the work is!

I think that there must have been two people who built this thing:

The first, who did shit proper, and the second who half assed OVER a lot of the good work already done.

Example: The distributor was HARD WIRED into the body electrical harness, there was no connector at all.

As far as the points through: does it have em? I didn't see any "points" only a magnetic pick up when I took it apart, so I dunno what points you're talking about Ted....

Bobby, I told ya those are not points, the distributor has magnetic pickup coils like the second generation CAS sensor. Here are the pics I took, and there are no points in there unless I'm missing something???

Sorry, then it's my fault.
I always though "distributor" = "points".
I never knew there were distributors without points.
Apologies for the confusion...

Ok, can you please point them out to me? (no pun intended) I thought that this is a magnetic pick up coil distributor?

... and WTF is nambla??

EDIT: Dude, that's just sick, what the hell?

The pieces up top are a give away as to it being points. The metal pieces on the upper side of the "tree" make contact with the specific points which then transfers the energy from the coil to the spark plug which is struck.

Umm, ok, I get what you mean, but I have never heard of those being called "points" isnt that just the distributor rotor?

I thought you meant BEAKER points, like these, which the dizzy obviously doesn't have, proving what I'm trying to say.



No matter what was actually being called "points" or whatever, usually when someone mentions "points" on a distributor they are talking about breaker points. Breaker points "Break" the ignition circuit every time the distirutor cam pushes them apart. They are a very outdated design that usually cant handle high rpm application well, so with time, the breaker points were replaced with a magetic pickup coil. It functions simillarly, but does not have any parts to wear since the trigger wheel does not touch the pickup itself.


I dont recall what the part you are talking about is called, but they are just contact "points" on the distributor rotor that yes, do wear with time, but that is just the way a distributor is designed.

On the other hand, breaker points are very well known to wear, usually lasting no more than 30,000 miles on an average passenger car. however, this distributor does not have them.

Conclusion: We are arguing about two different things. When RTED mentioned "points" I thought he meant a breaker point type distributor, which this one isnt, and made that comment. You are saying he meant something else. I'm not trying to say you both were wrong, but my statement about this being a magnetic pickup coil type dizzy is still correct.


I'm don't know everything, but I'm shure as hell trying to learn, so please teach me anything you know about this matter, thank you.

Does anyone know what you have to do to make 350z wheels fit on a fc?

I do!

Step 1: Throw 350z wheels in garbage

Step 2: Buy some cast aluminum replica wheels in any desired size or offset.

Step 3: Look good and save a bunch of money on your car insurance with geico!


...but really, you need to machine out the center bore, and use spacers, and still have wheels that look terrible on the FC.

rx8 wheels look way too much like Z wheels and would actually fit pretty easily.

/\ It's just that there is someone that's selling 350z wheels locally for kinda cheap, but I still dont think that it's worth the money, especially with the machining, i'm not sure on how that would affect structural integrity?

Yay, I taught the almighty RETed something new!

But seriously, the distributor system is way outdated anyway, and if you mostly work with modern Hi-Performance EFI systems, then it's not unusual for people to not be as knowledgeable about the older distributor system.

A good example is how I have very little experience with carburators, drum brakes, and steam engines.
