does a 3s distributor fit on a 5s? im looking to upgrade my electrical system with bigger wires and such but there are no distributors for the 5s
i tried looking here but couldnt find anything so if there is a thread could you link it? thanks

The 5sfe does have a distributor, it is pre 97 maybe?
My 94 GT has a distributor for sure.

If you want to upgrade the ignition system I would suggest using an aftermarket external coil which could utilize the existing components. You could also switch to something like the 6AL or 7AL MSD Ignition module. It is capacitive discharge, so it would provide more complete ignition because it works by firing the plugs multiple times at higher power rather than one long weak spark. The MSD ignition is also capable of generating spark well over 10,000rpm.
Of course if you switch the ignition module, there will be some modification required. While you could probably piggyback it onto the existing sensors you would negate the need for the Ignitor and ECU controling spark. And Im sure the ECU is much better at mapping a 3-dimensional ignition map than an MSD ignition.

If you change the size of the plug wires without upgrading the coil you will shorten the spark duration. The wires have some inherant resistance, lowering the resistance makes the spark shorter but more powerful, increasing the resistance will make the spark last longer but it will be weaker. The toyota engineers had the math equations to calculate this, and Im sure they selected a wire type that was the best compromise between spark strength and spark duration given the OEM equipment.

Bigger plug wires isn't always better. You won't gain anything going to 10mm wires if that's what you're looking for. The only time you should make your plug wires bigger is if it is necessary.

i wanted to upgrade to an msd system but i couldnt find a 5s distributor to accept it

let me clarify, i have a 95 GT and i want to upgrade the ignition system with msd blaster and ignition system for a better and stronger spark

to gain what? less bank balance?

there is nothing wrong with the OEM ignition system. it will support anything that you do to your car.

JDM YO!!!

nah, get a used one if yours aint working... someone is parting around here, if it aint broke leave it alone

a new toyota genuine rotor, cap and lead set and some new plugs is all u need

do the air filter, fuel filter and an oil change and away u go
