I picked up a wide ratio 5speed from a 78Z. I’m going to put in my 73 240Z. Do I need a clutch kit for 70-74 Z or the later 75-80 model? TIA.

Inspired by Captain Obvious, I thought I would go out for a last tango last night before they salt the roads. As it happens less than 1.5 miles in, accelerating off a roundabout at 2.5-3k rpm, the car suddenly lost power with afr at 18+ and struggled back to idling after pulling over. I suspect the diaphragm on my good mech pump has also started to go in the same way the other one did. Last time this happened I swapped the pump on the side of the road and it’s been perfect until now. I do have a NOS diaphragm, but I wonder if that will go too at some point. So I am looking at installing a tandem electric pump or possibly just going electric full stop. There are …

I find myself in an unusual situation today. I’m re-assembling a nice post body restoration early VIN 240 and put the engine/trans back in yesterday. It doesn’t fit. Well, the transmission mount doesn’t fit. The mount is now much wider (by two freaking inches!!!) than the transmission tunnel mount holes thanks to the lunk head that did the floor replacements couple of years ago. (Not me!) They’v even welded the old transmission mount plates on the side of the tunnel in the wrong position longitudinally as the holes are a good 3/4 inch behind the trans isolator mount stud. Custom trans mount here we come. I can’t even trust they welded the mount plates i…

I’ve inherited this electronic ignition system, it was working fine before I tore the engine down and assume it will be ok when I fire it back up. I’d like to find the appropriate cap and rotor for the short term AND know exactly what I have. To this uneducated shade tree mechanic ignition systems are the ultimate form of black voodoo magic. If anyone recognizes these parts please chime in. I’d like to upgrade to the 123 but I think some ZTherapy carbs may predicate the dizzy... short term Please let me know if pics of other parts would be helpful. thanks Tom

The hoses going from my fuel tank to the expansion tank are all rotted and leaking. My Z is a daily driver so I don't have time to pull the tank and replace the hoses. I cut and plugged all but one hose and routed it to the filler neck hoping that would be enough ventilation for it, but it takes about ten minutes to get all the gas squeezed in it will take. There seems to be an air pocket in the top of the tank; from bone dry to full (for it) is only about twelve gallons. Maybe thats full, but someone told me it should hold more like fourteen. Any ideas on what to do (other than replace every hose)? Thanks, …
