So... this is my first new topic posting, and I'm sure its a dumb one but here goes. It seems my left turn signal/ parking light socket came loose from the assembly and the harness dangled/dragged on the road until it ate away half the socket. I've been searching for just a replacement socket online, but haven't found one that looks like it would fit. I did find a pair of used harnesses on ebay for $65.00, but that seems steep to me. Is it? Does anyone have a suggestion other than just suck it up and write that check?

Okay here is a wacky tach issue. Not really a must fix issue bit annoying non-the-less. So when I hook up my tach/dwell meter when tuning up our 1970 L24 engine I've noticed that the tach in the dash is reading much faster than my tach/dwell meter hooked directly to the coil. We have stock coil and vac adv dist. I don't know if the tach is original with the car. I assume it is, but we haven't torn into the dash yet. Here is the issue: When my tach/dwell meter reads 700rpm the tach in the dash is reading about 1100rpm. When I slow the rpm down to say about 500 rpm the dash tach reads about 850rpm. When the engine rpm goes up to about 3000rpm the inside tach reads close…

Our Z's use ported vacuum for timing advance. So what's the theory difference between port based vacuum advance and simple manifold vacuum advance? I'm not a timing guy, but I got the basics: Manifold vacuum is highest at idle, lowest at WOT, and in-between when in-between. Port vacuum on the other hand, is zero at idle, highest just above idle, and the same as manifold vacuum everywhere else. I guess the question is "why"? Why do they eliminate the vacuum advance at idle? What's the advantages? Normally, the vacuum source is used as sort of an engine load sense device. In other words, when the engine load is low (like at light cruise) the mixture is lean and you need mor…

Planning MSD 6A (from amazon)with stock points distributor. Will also get a coil and Tach adapter. Anything else I need to go with it? Do I still need a ballast resistor? One comes with the coil. Anything to watch out for? The box will go near the other electrical stuff by the passenger footwell, I guess. Not very experienced with electrical stuff so hope it's easy. Wanted the shop to install it but not enough money after tax day. Is it worth extra $40 for 6AL? Never redline it anyway.

Hello All, I recently picked up a early 74' 260Z with 25k miles on it for free. It is all original, and still has the CT plates from 92'. Has some minor rust problems and lots of mouse droppings. Also has uncracked dash and besides the seats, a perfect interior. I've got it running pretty good now, but am struggling with the charging system. So far I have tried the following: - Three different voltage regulators - Cleaned all connectors - Tested alternator, and is fully functional - Checked and cleaned fused links The battery voltage is around 12.6V, and doesn't vary mutch when I change engine RPM. Any suggestions appreciated. Thanks, Pete

I bought one of Dave’s side-marker conversion plug kits from MSA and have installed both the headlight relay kit and parking light relay kit. Both of these were very straight forward and installation was pretty much a plug and play affair. Now I am working on the side-market conversion plugs (SCP) and having an issue getting the side-marker housing isolated from the body. The instructions say to use an Ohm meter and see if the black wire going from the housing completes a circuit to the body. I encountered a complete circuit tone so I widened the holes in the housing and put some electrical tape around the back of the housing and tried again. Once installed I conti…

I am next to installing an AC system on my 240z. I have noticed that on the right hand of the engine there seems to be 4 holes to install a bracket to mount a compressor. Where can i purchase this compressor mounting bracket? Will the ones from a 280zx fit? or should i manufacture one? I saw one on ebay from a 79-83 ZX. Anyone?

Install a lever next to the choke and wire it to the vacuum advance connection inside the distributor (remove the vacuum advance canister). The next step is to adjust the cable so that it swings the full excursion of the advance. The final step is to set the nominal advance with the lever in the middle. In theory this will allow you to set the timing in the middle then push it to dial up more advance for cruising on a highway and pull it to reduce advance for starting the car. I was trying to come up with a way to increase fuel efficiency then this eureka moment fell upon me . I think I hear Lazeum smiling You could also make the lever into an ejection seat activato…

I've always wondered where the 4500 RPM limit "rumor" about GM's HEI module came from and finally found the source, in a book David Vizard authored called "How to Build Max-Performance Chevy Small-Blocks on a Budget". The relevant pages are actually available on the internet - [h=1][/h] How to Build Max-Performance Chevy Small-Blocks on a Budget - David Vizard - Google Books I was a little disappointed after reading all of the the various things that Vizard has written. In the end it seems like he's using the old technique of selling aftermarket products by pointing out "flaws" in existing product. I think that he started by selling MSD product, then went to DUI dist…
