Just Another Damned Z Car Project Thread

Thanks to @Yarb for the referral. Show we’d up yesterday but I didn’t check the Mail until today.

That’s a lot of clamping surface! What clutch and pressure plate should I use? 

[Yarb]

ZXTurbo/ 2+2 is the 240mm clutch I believe.

[conedodger]

So given that my motor is a Rebello 3.0 with 300HP potential, what brand of clutch? A quick search shows stock, Centerforce I and II, Dual force, ACT. 
What experiences have you guys had with these and what options am I not seeing?

[conedodger]

I’m at an event. A Porsche event actually, and they had door prizes during the dinner tonight. I won a pair of these. I didn’t intend to do anything overtly non-stock appearing with my Z but heck, free is free so…

anyone have any idea how these wire up? Jeep I think?? Second damned Jeep part on the car now… hmmm.

You'll probably need some headlight relays. Also, you can remove that pigtail so you just have the 9003 connector that plugs right into the connector for the sealed beams. Too bad you're on the other side of the country. I've been installing headlight relays that I hide behind the center stack so no one can see the modification.

Thanks @SteveJ! What relay do you suggest since we can’t seem to coax you across the country? You know, we’ve got this lake here that a lot of people enjoy seeing?

You will need the relays that MSA sells;

The reason you need these is because of the way Datsun wired the headlights which is a problem for LED's because diodes (the "D" in LED) only allow electricity to flow in one direction. Here's a thread I started that explains why you need the relays.

@w3wilkes provided the link I would have. Dave Irwin did a great job designing the harness. The way I do it takes a little more effort, but I put extra effort into hiding relays and the wiring. I haven't played around with enough cars to make a kit for other people to install.

Since I also did the 60 amp internally regulated alternator I "hid" the relays in plain site by mounting them where the old voltage regulator used to live.

[conedodger]

Wilkes, cool work! I grabbed your pic and I will do it too! 
 

tell me about this 60amp alternator? Why not one of the 100 or 140 GM 12si alternators?

[w3wilkes]

Since I've replaced all my bulbs except the dash lights with LED to take the load off the wiring including the headlights with the harness upgrade mentioned before the 60 amp alternator seems to be more than enough for my needs. I did do the Retrosound stereo and will be reactivating my dealer installed A/C eventually I think I'm more than good. The 60 amp upgrade I used was this from MSA that eliminates the mechanical voltage regulator where I mounted the headlight relays (there's a note at the end for 73 cars to contact MSA for some options)
