Ive been thinking about this for a while. I've tried some things that no one else has listed as their mods, so i wanted to start a thread where we share our experiences on misc parts.
I will start by telling you about the starter i bought off ebay from a seller by the name or "Datsun Parts"
heres a link to the same thing:
like any starter, the install was very simple and straight forward. i however went for the gusto and also purchased their "Starter Relay Kit" (Link Below
i didnt attempt to start the car without the two installed together, so i have no idea if one works well without the other, BUT my OEM starter wad started to decline very rapidly in performance, it would slowly struggle to get the car to start for long periods of time, and slowly spool up eventually building enough speed to start the ole L20.
with this new setup, it spins very fast, BUT it may just be my particular setup, but it takes a while for the first start on my engine. i imagine its due for the most part to my timing, but none the less when it DOES start, i dont have issues for the rest of the day, literally BUMP the key and it fires right up. i have to say it was a great purchase, and i recommend this setup to anyone else who has a struggling starter.
here is a side by side with my OEM starter:
and the starter relay:
this was really easy to wire up , just 5 wires, i had to extend them all of course because the pigtail is really short. if it came with 3' of wire, it would be awesome, and much easier to hide, but no matter. i have no idea if this really helps much, but i read about a lot of people using similar setups on their old Z's, so i took the dive, and at only $15 it was worth it.
