distrubutor question

[murderwagon]

i have a distributor with the ignition module on it on a l20b i bought. i have no idea what the motor came out of but i need to buy a cap and rotor for the distributor. so i need a year make and model for the local parts store. thanks

EI L20B dizzy is the same as any other. '78 510 should work fine.

DQ Volume 4 Issue 2 - Electronic Distributor Guide - Installing an electronic ignition distributor is one of the most recommended and a relatively simple modification. The benefits are clear: You get better reliability, more accurate timing and a more powerful spark that delivers easier starts, a smoother idle and virtually eliminates missing and stumbling at cruising speed.

^will have your distributor listed by part number on the body, can determine year, advance, etc.

thank you i have had it on for about a year with no problem. but its starting to skip a bit and the cap is pretty gross. its a cheap aluminum terminal garbage cap in the first place. time for an upgrade

The only upgrade cap is the JH63X. Generally NLA from parts stores, but they are on eBay. I have one, it is better built, with copper contacts. Probably more a longevity thing than outright performance, but...

I have used the BlueStreak ones as Okfine has mentioned. that was made by Standard Motor products.

They sell another version with black cap and bradss contacks. close to 20$ retail.
Match box distributor I usually just say 79 200sx rotor and cap. But I believe all the way doown to 1975 will work for the rotor&Cap

Be honest I havent changed a cap in about 8 years on any of my datsuns. So maybe just clean them. swap in new plugs( I rarely change them also) and ck the timming and ck the valave lash.
tighten the carb intake bolts

motor is brand new valves are set, new ignition module, plugs, wires, coil. im positive the cap is junk. thanks for the advice thou.
