The Lucas 45D Distributor replaced the Lucas 25D in 1975. It appeared in many of the British classics that we know and love, being the most used production distributor in British / BMC vehicles. This electronic distributor replaces the points type on your 1275cc Mini, Spridget, or Morris Minor with an electronic type but with a curve compatible with the 1275cc engine.

The Powerspark 45D distributor is a brand new casting, taken from an original model. Being such a popular distributor, our 45D is a big seller for classic car enthusiasts worldwide in this new, electronic form. Electronic Ignition models replace the points set with the patented Powerspark Electronic Ignition module.

Powerspark Electronic Ignition is the original electronic ignition conversion for classic cars, giving reliable starting and hassle free ownership.
 
 
Question:
I have a 65 Sprite with a 1275 engine (positive ground) would this distributor be a good choice or what do you recommend?
Answer:
Most of the electronic distributors are for negative ground systems, including this one. We do offer Pertronix kits to convert your points dizzy to electronic that's positive ground specific - both for 23/25 types and 43/45 type distributors.
Powerspark does offer a positive ground 45D type distributor (without the 1275 specific curve) but it's more expensive than the PSD4-75.

Question:
I received my new ‘57 MM Traveler on Tuesday. Spriget upgrade years ago. Described as 1298 cc. Hard to find much info, compared to the 1275. The shop manual (Brooklands) arrives Wednesday. I want to work to tune her up for a weekend ride. Are the ignition components interchangeable between the 1275 and 1298? I’m going to need all the basics—I am guessing/hoping you keep the basics in stock? - cap - wires - points - condenser - plugs Also feeler gauge, SU balance tester, timing light. Do I need imperial gauge tools? What else would you suggest?
Answer:

There was no factory 1298cc engine. 57's came from the factory with a 948cc engine and a smoothcase 4-speed gearbox.

It's possible you have an overbored 1275cc from a Sprite or Midget and ribcase gearbox as this is a very common upgrade.

Overbore sizes of the 1275 are:

+0.020" = 1293 cc
+0.040" = 1310 cc
+0.060" = 1330 cc

I think a +.030" is around 1301cc so maybe that's what it is. Anyway, all of the components for a 1275 are the same regardless of the overbored size. All the hardware is Imperial not metric or Whitworth.
We don't sell feeler gauges or timing lights but do sell carb gauges. You'll need to know what carb(s) you have and which distributor.

Question:
I have a 1960 Morris Minor Traveller with a 1275 engine (I believe it's out of a MG Midget.) I am out to buy a new distributor the choice is between the Powerspark Mini Standard Electronic 25D and 45D Pre-A+ Electronic Distributor With 1275cc Curve, but I am not sure what is the CURVE is about, do I need that?
Answer:
The curve is the advanced curve that the distributor produces. The 1275 curve is more appropriate for 1275 engines but any pre-A+ style distributor will work for you as long as you're careful when setting the timing.
