Hi everyone, This is a really stupid question that I have. Which way do the control arms go on the car? I stripped my Z to the shell and am now in the process of sand blasting, painting, and finally putting everything back on. While I was installing the new urethane bushings I noticed that the control arms had a swept back look to them. So I looked on my parts car and it looked like they sweep back to the rear of the car. So I installed the control arms and bolted the strut/spring assembly to the frame. The problem I run into is the tension rod looks like it doesn't line up correctly with the control arm. So I was just wondering if I have the control arms installed backwa…

I'd like to know what head components are interchangable between all L series engines from the Z cars (i.e. E88, E31, N42, N47, P79, P90, etc)? Obviously the valve cover is but how about the cam, cam towers, valve springs, etc? I'm asking because I have a complete P79 head that I have listed on 3 forums including this site and nobody has expressed any interest, as I expected, so I'm wondering if there's any value in taking it apart and selling the smaller parts of it mentioned above.

Hey hows it going. I have a 240z manufactured in 10/71. It has the stock l24 block with an n42 head. Its mostly stock except for dual high flow air filters and no smog equipment. Im planning on installing a centerforce 1 clutch and pressure plate, electronic ignition distributor, msa 6 into 1 header, msa 2.5 inch exhaust and an msa cam. I was considering their stage 3 cam. They say it has a rougher idle and pulls hard from 3000 to 6500. the numbers on it are Grind: 17034. Lift(In/Ex): .460/.460. Duration(In/Ex): 270/280. This seems like a good cam for my situation. Im also planning on running some smaller mods, like a euro single groove crank dampener, since ive removed m…

Take a look at this picture of the piston top from my L24. It's got 200K miles and is about to be replaced. The compression was low on all cylinders and rose with the addition of oil. Are those shiny clean areas around the edge of the piston from blowby due to worn rings? I've got an L28 that is going in, and this block will likely not be used again by me, so I'm just asking as part of my ongoing Z education.

Ok heres the problem: When i touch the exhaust tip the whole thing started moving, and it wobbled for a while, looking under the car shows that it is attached to nothing, it goes straight from the header to the end. I cant see any places where the thing might have mounted. So can someone give me some advisory on what to do? Thanks alot.

I rebuilt sometimes ago my fan clutch as per tech tip on this site with silicone oil. The O ring was good and I put gasket sealer before reassembling both halves. I noticed today that I have oily spots on the underhood as before the repair. The fan blades also have black oily deposits and the clutch too. It seems that I have no choice but to buy a new fan clutch. Any comments or suggestions

On the '74 I have triple mikunis... Those of you that are running this or any triple setup, what are you running for fuel pressure? I assume that since these are not a draft style carb, the pressure is important as far as performance goes, not just keeping the bowls full.... At a sustained rev (3k RPM) my pressure is dropping to 2 LBS or so and at an idle it's at 5 LBS. I think that the motor is low on pressure fuel wise which is contributing to performance issues as far as demand goes, I have a great pull in the first few seconds then the engine seems to "drop off" a bit. Any suggestions as far as fuel set up goes? I am currently running an electric pump that has a ra…
