[TR] 123 Distributer for TR6

Hi Creig,

I can speak to the 123 distributor. I have been running one in my TR4A since
I finished the restoration in 2013 with no problems at all. I have the
earlier one that has the advance curve controlled by a little hexadecimal
switch which has several preset advance curves.  Newer models now can be
programed using a laptop.

As you may know, the 4 cylinder motors are set up with the tach drive under
the distributor so I didn't have to worry about getting an electronic tach.

The distributor was pricey but it has quite a few nice features like
balanced spark and a built in feature that turns off the power to the coil
if the ignition is on for more than 30 seconds or so with the engine not
running so you save the coil from overheating.

There is a guy in the states that sells them which is a good thing.

Subject: [TR] 123 Distributer for TR6

 

I am building a TR6 engine with Goodparts triple Stromberg, GP2 cam etc.  I
am seriously considering the 123 distributer.  The drawback is the high
price to buy the unit.  Then the additonal high price to convert the tach to
electronic.  Searching online I saw that a few years past, there was someone
who put the 123 electronics into a TR6 distributer housing so that the cable
tach could be functional.  I have a few questions trying to see if there are
any other good options other than 123 distributer and electronic tach
conversion.

 

1)  Is there anyone who currently sells a TR6 distributer with the 123
electronics?

2)  What is the best mechanical distributer to compliment a healthy TR6
engine build?  (Instead of the 123 distributer.)

3)  I have seen mechanical drive units that will drive a speedometer cable
at the correct RPM to correlate to GPS position.  Has anyone done the same
for a tachometer?  (Engine electronic signal translated to a motor to drive
a tachometer cable?)
