I have a L28 in my 240 with a ZX alternator upgrade. The belt fits correctly in the alternator pulley and the water pump pulley. As you can see it does not seat all the way on the crank pulley. Do I have a L24 pulley on there do you think? If they are in fact different then I guess I need to get a L28 crank pulley.

I have a copy of the '73 Factory Service Manual and I'm noticing that unlike my Porsche Factory Service Manuals, there is no mention of fastener sizes. I'm trying to dress out my new Rebello engine but I'm having to constantly run to the hardware store. Has anyone compiled a list of the sizes and locations for the engine?

I recently installed the Crane xr3000 and used the 14 gauge wire - per the Crane instructions. However my tach is not steady and it will drop sometimes between shifts. It just generally works poorly. I have heard of a fix for this - anyone know what it is.

So my original metal fan and clutch aren't decoupling. Nothing new to me, since I got the car on the road last year it has never worked. Since I can't get a fan clutch for the metal fan (and because its dangerous) I will replace it with plastic fan and new clutch to match. I have some plastic fans from a friend, but I've read a bit about them cracking and inspected mine. These black lines are cracks, although in some places they line up with the molding lines of the fan. Can get a small screwdriver down into them. No bueno. Guess I won't be using this 8 blade version. The 7 blade one I have looks better, so I'll go that route. Or just buy a new o…

While cleaning up my transmission for installation I was pondering this. If i drill a new hole where the X is, wouldn't that create a shorter throw. Would it raise the pivot point? What problem might it create? Need help from you engineers. Don's iPhone using Classic Zcar Club mobile

I have been happily running a 190°F thermostat for a while now. I am about to head out on a road trip in June to Austin (ZCON yeeehaaa), and was thinking I should flush my coolant system to make sure it is tip top. I have an OEM Nissan 160° thermostat sitting in its box. I am concerned it may not be warm enough for the triple weber manifold. Anybody else run 160 thermostat?

In five years in Florida I've yet to experience vapor lock in my Weber down draft equipped 240Z. So my question maybe more academic curiosity raised while I was working on a different problem. My problem has to do with hard starting after my car sits for several days. I can't say I ever experienced starting problems when it served as my daily driver. Now that I've moved on to others projects, the Z often sits for 3-5 days without starting and hard starting has raised its head. At first I thought I caused it when I converted the sequential 2 barrels into synchronous operation with a kit from Redline. Also I re-jetted the carbs to better handle the ethanol laced gas we…

I have a 5 speed competition, close ratio, 5 speed in my 1976 280Z that was installed in 1976,77. I purchased car in 1979. The part #is 32010-N3200. It uses Servo type synchronizers. I'm looking for a synchros and friction pads, seals and bearings. I believe standard seals and bearings work. Any suggestions where I can locate these synchros and pads?

Last year during an 8 hour endurance race, my 260Z started missing and running like crap before it dies completely. We tried to diagnose the issue at the track and finally had to throw in the towel that race. We could not get the car to start no matter what we tried. Everything looked normal with the timing, valve springs, plugs, etc, but it wouldn't start even on starter fluid. We parked the car in the garage and until today, we had no idea what was wrong or how much damage was done to the engine. Today, we pulled the plugs and looked in the cylinders with a borescope. Everything looked great. We then looked down the front cover and all looked normal. The cha…

I ran into a local gauge manufacturer who actually sells a 10 Bar oil pressure sender. I asked if his sender would work with our Series I 0-140 psig gauges and he replied that he know without more information about our gauges. ( 1 bar is 14.7 psig) What is unique about his sender is that it is not a dual purpose sender like almost all of the other senders available for our cars. Dual purpose senders are intended for use with idiot lights and go open when oil pressure goes below approximately 10 psig. This is what causes our gauges to go to zero while idling after pulling off the interstate. His sender does not have this feature. For those who do not know, Series…
