I forgot about these but just came across the picture again. I figured they deserved a re-post.

Hello everyone. -I have a 3.0 motor that red lines at 7,200 rpm with triple mikuni's -I do not like the fact the tuner used a stock distributor and set the base timing at 20 degrees. The idle is not the best. -So I am going to do the electromotive XD200 programmable ignition with Hoke perf. trigger wheel/mount/etc. -Are there any timing recommendations from idle throughout the rpm range to 7,200 rpm? Thanks, GI

I have an early 5 speed transmission. I'm guessing it is from a '79. I had the transmission rebuilt recently. After the rebuild I didn't have 2nd and 5th gear. So I yanked it out and took it back to the mechanic. I put it back in Saturday and I still don't have 5th gear. It shifts flawlessly 1-4 and reverse seems ok, but when I put it in 5th it pops out when I let out the clutch. Before anyone goes there, the mechanic is used by many hear and considered to be reputable. I'm frankly pissed but I'm not going to call him out. My questions are: Does anyone have any ideas why 5th keeps popping out and if I leave it in for know and just use gears 1-4 am I going to mes…

Greetings Z buddies.... Been a while since I posted as I have been working my website and reignited an old passion of mine with collecting mechanical watches. Guess I am getting old.. But seriously... I have finally acquired a 5 speed from a 77 280Z and have been calling around to get it rebuilt. It seems to work fine on the garage floor.. Spins freely and feels smooth... but before I put it into my car, I want to go through it completely. Having said that I am getting prices to rebuild an old 5 speed in the 900-1300 dollar range. That seems excessive since I had my 4 speed redone for 650. well the mechanic in me sort of wants to give thi…

Hi, everyone, My first post... So, I am helping a friend with his 74 260z he just bought. Tried to get it running today. Once we got the firing order right (original owner had the firing order wired the wrong direction around the cap, no wonder it wouldn't run) It has a holley 4 barrel (390 or 450cfm haven't looked into it very much) The car has both an electric and mechanical fuel pump. We came to the point that no fuel was getting through the electric pump. After a little searching I just found out that there is a filter inside the pump we need to check out. But, anyways. My question is does he need to run the electric pump or do you think the mechanical pump will keep …

in the interest of science, I did a "cranking vacuum" test. I have never heard of such a thing but read about it somewhere. Thought it would be something to measure and make note of Completely stock NA L-28 manual setup for a 800 rpm idle. Warm up engine to about 150f (indicated on gauge) pull brake boost line and hook up HF vacuum gauge. using remote starter (ign off, plugs in) crank engine for about 10 seconds I get about 7" of hg with no noticeable movement of gauge. maybe 120ft above sea level. throttle plate closed. My normal idling vacuum is about 17-18 a little better if I run the idle mix a bit richer (about 19). I only foun…

Today after taking the car for a couple of nice spins the lower radiator hose came off the radiator inlet. Is this normal due to high speed. Any clues to the cause of thiS?

Hello, I have a question that I have scoured the internet to find the answer to no avail. I have an early 260z that was automatic so it came with the dual pickup distributor. One for timing advance and one for retard (starting and when car comes to operating temp). My question is can I simply remove one of the pick ups in order to finish my MSD box install? My question was partly answered elsewhere however I believe that member is no longer active. This person stated that they converted their 2 pickup to 1 and it ran fine. Not sure how much truth there is to that because he did not elaborate on which he removed or what he did exactly. If anyone has experience with t…
