You have a number of aftermarket ignition module options for D1’s noting pre 94 update model the amp was located on the distributer and post update located away from heat beside the coil. I have also added some matching coil info as ideally the 2 should really be changed as a pair, funds permitting.Quote:

The advantage of this alternative is you can swap out your OEM coil to something cheaper and arguably better.
2 The following are Plug and Play aftermarket units and match up the OEM coils which were either Lucas or later on Bosch units. The advantage of these is they are plug and play and the remote mounting plate/heat sink is used to fix very securely the rubber booted 2 pin plug coming from the dizzy (underneath and not shown in pics with 3 wires, 2 via the rubber plug and one being a ground mounted to the plate). Disadvantages are a bit more expensive and maybe not as good as the BIM 024 for gas, however that is bee utey’s territory.
a) Tridon TIM044 Australian made and which Bursons carry for about $100.
b) Automotive Ignition & Electronics in Brisbane Automotive Ignition and Electronics - Home import both a 2 pin (Pic 1) and 3 pin (pic 2) versions mainly for the trade but they do sell to the public. They sell these amps for $99.00 retail. Note while it may be a 3 pin plug on the coil harness for the remote amp style, only 2 pins are active.
c) You will find probably at your local LR specialist and on-line a number places in UK and US that sell aftermarket LR amp modules and some come with 3 pin plug adaptors for those with an existing 2 plug setup. I have had no experience with these.
d) A Lucas OEM coil will cost about $80 however Bosch are arguably better however a Bosch OEM coil (# 0 221 122 392) is a ridiculous $240 plus in Australia but 1/3 that in UK and US? Go figure? Working on the theory of getting rid of more things Lucas the better, I am currently trialing a older barrel style oil filled HEI coil made by Bosch (the BIC290 that I am assured works with LR OEM and aftermarket amps and can be found in Lasers, Sigmas and some Mazdas) to economise the plug and play amp module alternative. The BIC290 is only $35 new and apparently works so well to the extent it is used by some high end EFI V8 specialists instead of big name coils.
As a side note I have found LR amps to die slowly to the extent you don’t know anything is wrong until possibly the first symptom being a quick misfire occurring out of the blue. If your fuel mileage is a bit ordinary (say < 100 Klm / 20 litres) and you have checked out all the usual suspects with no problem, then a ignition amp on the way out may be the culprit.
