One of the two close ratio 5 spds that I rebuilt last winter jumps out of 4th gear on deceleration. It was rebuilt using the correct rebuild kit and I'm sure it all went back together properly. I want to open it up again this winter to try and fix it but I really don't what I would do differently, any ideas? Thanks, Chris

OK, I know for what ever reason the MN47 head is very controversial subject in the Z community. I know of a 81 Maxima being parted put in my town. And I plan to do a mild warm up of my L26 in my near future. rebuilt SUs, electronic ignition, exhaust, cam and a mildly ported head, is kind of the basic plan I'm thinking right now. something that'll be a bit quicker but can still be driven every day, that plan could very likely change fast, but we'll have to see. I searched a ton about it last night, and I found everything from its awful to it's the best L series head availible stock. I doubt either are true. We have a very old very reputable head shop here in town where Im …

I have a 1970 240Z with the original real end, but with a later model 4-speed manual tranny. The Speedo is reading about 10 mph low at 60 m.p.h. I don't know which speedo cog I have. I think it's the black one. Which one will increase the speed? Should I count the teeth and go to one with more teeth? Coop

Just installed the transmission in my '71. Very lightweight crosspiece I thought, and with only two vertical bolts holding it to 43-year old captive nuts, how much torque would it take to strip one out? I have some parts laying around from a '73 and notice that the transmission mount assembly is much more robust. I have to assume the factory was motivated to make this substantial change. Has anyone had some bad experience with the early mount coming loose? Installing this transmission reminded of something a wise old mechanic told me many years ago. He said "Only a bad mechanic blames new parts for this problems." I've found that to be 100% true - until now. On …

Just swapped one close ratio 5 spd for another almost identical close ratio 5spd and as I'm bolting everything back up I notice the angle on the slave plunger is way off and I had to pull the clutch fork back halfway just to get the slave to bolt up. This all worked perfectly on the other transmission and the only difference between the two trannys is the one that is out of the car has the tall ears on the shifter, and the tranny I just installed has the shorter ears.

For and driving environment like Oregon and Washington, what is the best thermostat for the early 240Z? I find them in 160F, 170F, 180F, and one other degree-rating I can't locate at the moment. Thank you!

I made my own RT mount for my diff and I'm thinking I didn't make it quite right and it is causing my clunk in the rear. I'm looking to compare my spacing between the moustache bar and rear control arm down braces to your set up. I think my diff mount pushed my diff and moustache bar back too far and it is hitting my braces for the control arm. Pics or a measurement would be great showing the spacing between the two. I am running a r180 diff and moustache bar

Recently found a reliable mechanic to tune my Hitachi twin SU Carbs. He managed to set the car to 1,100 RPM at idle due to the fact that i have a FAR 311 Race cam and the RPM needle will never keep steady. However after driving the car the following symptoms came out: 1. Car has power but is not running smooth it tends to choke when shifting from 1st to 2nd gear; 2. After 10 minutes of driving the RPM started lowering from 1,100 RPM to 500 RPM tending to stall; 3. Finally when arriving at the shop the electronic fuel pump fuse was blown and there was no fuel present at the fuel filter. 4. Replaced fuse and the car threw a flame from the exhaust when started. Now i am all…

Hello all. I recently found a 280zx turbo rear end which included disk close to me for 50 dollars. Would this be a worthy investment for me? I believe it has the 3.565 r200 rear dif, but I'll double check. I just figured for 50 dollars, this could be a steal and I should jump right on it. Thoughts?

I have a '71 240. It has the earlier, stamped-metal cross piece supporting the transmission. On the top surface of this piece there are two thumb-sized indentations, one on each side of the centre mounting bolt-hole. They cover about half the width of the cross piece. So my questions is, does it matter whether these are to be at the front or the back of the cross piece once installed? Makes sense I hope. Thanks
