I'm the proud new owner of a new-to-me 1974 260z. The speedo doesn't work. The previous owner said he thought this was a chronic problem with this model. If it is, what the fix. Also, I think the carbs have been changed over to dual Weber DGV's. This is based on the fact that the SAU on my 1976 MG Miget is side draft. I know I need to do some further research, but can anyone recommend a good book for adjusting the Weber?

I also recently purchased a '74 260Z (about three weeks ago). Mine is an early 260z manufactured in May 1974. I purchased it from the original owner. When I got it, the speedometer was working, but erratically. When I pulled it fro the dash, I found that the cable was unscrewed, and was just hanging on. You may simply need to re-connect the cable to the back of the speedo.

My car also had the carbs changed. Apparantly, the perfomance on the original Hitachi side drafts sucked. The owner told me that the dealer recommended to him when he purchased the vehicle in '74, that he switch the carbs for SU's (used on the 70-72 240's), which he did. Thus, I got mine with SU's, which appear very similar to the SU's that I had on a 1962 MGA.

It seems that we have a lot in common. Please contact me to ask any questions you may have, or to share experiences with your car.

P.S. -- I am planning to re-build the engine and am interested in learing about modifications that I can do to increase the output of the L26/E88 combination versus, rebuilding an L28/P79. I welcome any thoughts you may have.

I also have a 74 260Z I have never had any speedo problems but at some point my engine was swaped out for a 2.4. Iwant to redo the engine and i am in the same situation I would really like to put a L26 back in it for originality sake but the car does have 180,000 miles and I am not certain if parts availabilty for the L26 would be a problem I know Nissan doesn't offer the L26 through any contacts I've tried.
