Just got a turbo BA in the drive & will be doing a coil swap next week.

Anything I need to know that's not in a book ? ( I don't have a BA service manual...yet)
Will be getting fuel miser coils.

Background: 160 thou odd K's on odom, factory / unmolested other than a twin tailpipe set up.

Engine idles & revs fine, drives well with minimal right foot, falls flat on its face under load so coils are the first item on the list.
Car has been babied & has been semi stagnant for at least 2 years & not a lot of maintenance done in that time.

With BA Turbos i would only use genuine coils and plugs. Reliability of the genuine is proven.
And if your going to do coils you may as well do the plugs while your at it.
Not hard to do at all.

So do ford have their own brand / generic, or did they use a branded product... bosch, NGK ... ?
Plug change already discussed.

Is it also wise to use dielectric grease on the plug fittings ?
I've heard some horror stories of plugs & coils being corroded together.

Yeah it is a brand under the Ford banner,trying to remember/stupid scotch. , as mentioned they are well proven.
I'm using the coils that I had N/A in the XG's first engine in my turbo setup,Drifter Coils which are High Output coils with some good NGK plugs.
Have heard from others that they are good (turbo wise) but can't tell you first hand sorry.

All good. Job is done now & car runs perfect.

Brakes hadn't had love for a while either, both front calipers had 1 seized slider each, no rubber boot!
Again all fixed now.
I've never seen "offset" brake pads, but these old ones certainly were!

LUBE YOUR SLIDER GUYS!!

As a follow up, few things I wanna mention, for the sanity of others,

The coil change fixed the misfire issue, runs "as new" now, however getting to them was fun...
, the rear rocker cover bolts were a pain to access being against the firewall* & the fact they're allen keyed bolts, & access to no:6 spark plug was hindered for the same reason*.

Had to detach socket from ext' bar just to get it in & out of the hole (plug 6) & ALL plugs needed a magnetic tool to pull them up out of the head.
All 6 spark plugs were homed up very tight, alloy against steel threads played a role I reckon.
Sprayed wd40 on no:1 but made no difference extracting it, so didn't bother spraying the other 5.

One wiring plug on a coil had a broken lock tab, small ziptie secured it to the coil.
Small, round rubber blocks on top of each coil pack when you remove the cover they stick to the coils but refit into locating holes on the underside of the cover.

Had 1 bolt disappear when removing the top intake plenum.
A stupid rubber mounted bolt above the inlet manifold that vanished somewhere within the confines of the engine bay after the rubber portion snapped.
An "unseen" failure, only audible as the bolt fell to its new home!
