AEI unit, coil, rear brakes

 I had a couple of hours spare last night so thought id get some more work in on the car. The first task was to swap out the old AEI unit for a newer one. My car seems to be kind of what is known as a phase 1.5. Its 1987 so one of the early phase 2`s and apparently they used up a lot of phase 1 bits in the process. My AEI unit was mounted above the turbo inside the engine bay. Its a Bendix 209 unit which is what the phase 2`s used but its in the phase 1 position. My previous 2 GT Turbos were both 1988 and by then the unit was moved inside the bulk head next to the battery to avoid heating problems from the turbo. 

You can see in the pic here of the engine bay, just above the header tank the AEI coil unit inside the engine bay.

I bought a later phase 2 AEI, mines a 209 B this new ones a 209 C. Im not sure what the differences are, as the main difference is between phase 1 AEI 208 and Phase 2 AEI 209 which has a different ignition map and 500rpm higher rev limit.

I firstly opened the unit up and undid the 2 torx screws holding the coil in. Reason being is that my rev limiter & shift light units need to be wired directly to the coil. The coil once you pull it out you can see 2 terminals either side of the spade connector on the front. Handily they are labeled - and + so you straight away know which ones are plus and negative to wire the gadgets to.

I drilled a few mounting holes inside the bulk head and mounted the coil up. I then had to extend the TDC and knocking wires to reach, plus drill a hole for the main king coil lead to reach through. Luckily the lead set I bought was for the phase 2 so it was plenty long enough. I have to admit I do now feel a bit nervous as to whether the car will start now. Im always reluctant to change to many things at once incase of having to narrow down any problems!

I then couldnt resist fitting the back brakes, so I fitted new EBC disc, new calliper, new EBC green stuff pads and bearing.

 Looks pretty good! I then had to fit the brake line which goes from the flexihose on the beam (replaced by new braided HEL line) to the calliper. Luckily I had kept the old brake line so I roughly knew where the route was. I also hadnt broken any of the mounting clips in removing the old line so could re-use them. The new copper-nickel line was really easy to bend into shape and you can see in the pix, looks lovely.

 I also fitted new handbrake cable whilst I was at it. It looks like the pivot on the adjuster under the handbrake is seized so I need to free that off, but new cable fed through the rear swing arm and to the calliper a treat. I need to get the rest of the exhaust off first before I can get better access to the handbrake adjuster/pivot.

So thats about it for this update, more later!
