I will assume that the factory shifter will wear out sometime, so I am wondering if there are any aftermarket shifters ( like Hurst or B&M) that would work properly with the Jatco 3N71B? thxZ

as some of yall know, i overheated my 76 280 recently, and my machine shop tells me that the head is shot. now i'm shopping around for a new one, and i'm a little confused. my head is an N42. i've been led to believe that an N47 will fit my year and model too. what is the significance of these codes? what heads will fit my car? i'm also a little concerned about my block. the cylinders have some striation in them, and though my nail doesn't catch on them when i run my finger around a cylinder, it doesn't feel too smooth. i can't really afford to get them bored, but i don't want to get everything back together again to find out that the block needs service. should i be conc…

I have to rebuild an engine and I have some decisions to make. I have a rather early 1970 240Z engine (it's a spare that I'm using as the foundation of my rebuild). I am on a 'no money' budget of course, who isn't these days. With that said, I want the most bang for my buck and am not out to build a monster engine...that will come later when I have the money to throw at an engine. This engine has an E31 block and E31 head. I can do a stock rebuild on this and call it a day. Or I can pick up an N42 block locally for $50 (includes crank, pistons, rods all disassembled) and build from there. The condition of any of these parts is a question mark. They may be fine,…

Getting hot here lately and want to have a constant fresh fuel supply. Was thinking about plumbing a return line in. Whats the best way to go about this? anyone have pics? Also what are people doing with the overflow lines with itgs air cleaners and such. Dont like the idea of gas possibly coming out on the headers. Currently there is two lines teed together run in front of the radiator if it where to overflow.

I am parting out a 240z with a good motor. A fellow has asked if it will work in his 280z using the 280z fuel injection setup. I don't see why not but I certainly do not know for sure. Any thoughts? Leonard

OK, so I did a valve job to fix a bent valve, and am seeing something weird- lower, but more even compression across all the cylinders. Before I was seeing 175 +/- 5 psi, now I am seeing 155-160. 2 ideas- valve timing is slightly advanced (2 deg on the cam), maybe due to new timing chain guide which is giving a slight inward curve to the tight side of the chain. My other thought was could the carbon buildup on the head and pistons have raised the comp by 15psi? It didn't look that bad, but I don't have much experience to judge by. Obviously its all cleaned up now after. Head was milled 0.003". Valve lash are all properly adjusted, wipe pattern double checked and OK, cam O…

As the title says, I want to replace the throttle linkage to fix my sticky throttle situation that many Z people experience. I know of the two fixes that are popular, but I have not been able to find anybody selling these linkage pieces... its the next thing to fix on the old girl...

Has anyone ever removed a differential flange from the differential? I need to switch the flange from my 75 R200 over to an 81 differential so the driveshaft will bolt up. Is it very difficult to get the nut off and how did you go about it? Thanks for any help.

Im just curious and dumb about this question that I like to ask.. Does the L28 engine fit with the SU carb manifold? I know it seems like its the same engine from L26 and L28 but do they bolt up... I really appologize for this question but I need to know

Hey guys, I have my engine sitting on the floor in the garage, and I have not rebuilt an engine before so I would like a tutorial to help me with the process. I would take it to a mechanic but i want to experience it myself. I have been lookin around and haven't found a lot of tutorials on this. Does anybody have some good links to engine rebuild tutorials for the the 2.4L? Thanks Frankie

Here's my situation, my daily driver has a smog problem and won't pass smog so it's time for it to go. I have about a month left on my tags. I'm going to pull my 73 240 out ( been collecting parts for it to do a total resto) and put it on the road. I have to get hold of a short block to get it running so I figure I'll get a 280 out of the junkyard. I have a fresh E-88 ready to go on. I will do gaskets and seals, timing gear set, oil pump on it. Do I use a 280 timing gear set ? Do I use the 280 timing cover ? Will a 240 distributor work with a 280 timing cover and oil pump. Thanks

i recently tried to start my 73 Z for the first time in ten years and some weird metal scratching sounds were coming from the head. i removed the valve cover and noticed the back half of the cam wasnt getting oil. The base of the back spray bar was bent and oil would leak out there instead of being sprayed on the cam. Furthermore, the short spray bar in the very back was loose and almost failing out (as seen in link) http://www.classiczcars.com/photopost/data/500/medium/IMG_6174.JPG i have been searching the forum for a long time now and found tourniqet had the same problem but didnt find any posts that explicitly had an answer so, lets settle this topic once and for a…
