Re: need a new coil any recomendations?
Cap adaptor, cap & Rotor are under $30 for the premium ones with BRASS TERMINALS, no reason not to upgrade.
All from a '82 Ford F-150 Pickup, will bolt right on your distributor and work like stock components.
You will have to change spark plug wires.
Try from a '93 4.0 Liter Jeep. Most people report they fit really nicely.
If you want to, you can go to NAPA, get a ignition coil connector.
NAPA P/N ICC-1 (about $13)
And then trade the factory canister coil for the late model E-core coil.
Order the coil for a '92 Ford Escort. (between $15 & $50 depending on quality at the discount auto parts stores)
What this upgrade will do for you....
Cap Adaptor, Cap & Rotor
Cap adaptor will raise the rotor up and away from the distributor housing, and cut down on the number if firings to ground. When your cap and rotor nose get a little carbon on them, the spark energy is just as happy to find ground inside the distributor housing rather than going to the spark plugs.
The larger Diameter cap, along with a much better internal design of the cap, will keep cross fires (spark energy going to the wrong terminal) and multiple fires (spark energy going to two or more terminals) to a minimum.
You also get the added benefit of the new HEI style plug wire terminals that leak less spark energy out, and keep moisture, dirt, grime and corrosion out better.
The taller and longer rotor will keep the spark energy up and away from the distributor internals, and it will get the spark to the correct terminal, with more room in between terminals with the larger cap, the spark will be more likely to go where you are trying to direct it.
Remember to use BRASS terminals only, otherwise you are wasting time.
(Aluminum terminals in the economy caps are for sh*t)
You are using plug wires that were designed to keep radio noise down in WW II aircraft.
By upgrading to the newer style plug wires, you are gaining several benefits.
Better noise suppression, more spark energy transfer to the plug, less spark energy loss through the wire and it's insulation, and much better connector ends.
The older 'Socket' type spark plug terminals are crap, and they will cost you performance.
By replacing the older oil filled canister coil, and going to the new style E-core coil, you will increase the three important components of ignition spark energy.
Duration. How long the spark lasts in the cylinder. The longer the spark lasts, the better chance you have of getting that cylinder to ignite and make power.
Voltage. You will need enough voltage to light the cylinder even under adverse conditions.
Amperage. You will need enough 'Electrical Volume' to keep the spark energy sustained to get every cylinder to fire every time.
By switching to the E-core coil, you will increase all three necessary components, and there are no draw backs.
The entire upgrade will...
Work with your current factory module, will decrease your emissions, increase your horse power, torque, fuel milage, top speed, midrange power, your idle quality will improve and make your morning starts faster and easier.
It's also just tune up parts that anyone can install...
Cap adaptor, Cap, Rotor, Plug Wires, Change the coil, have a beer....
