Hoping to get a nice definitive list of what's best to get done to early-ish cars.
I recommend:
1. Suspension wishbone upgrade - Had this done - about £75
2. Replace off centre early rear-end and sprocket with later one - Had this done - belt quiet once more. Don't have enough miles to know if this is going to be a better long term solution but it's very nice to have a centred rear wheel!
3. Comfort suspension change. Steering less 'alive' and feels like more understeer, but much lighter and much less kickback / bumpsteer over all but huge bumps
4. Ecu software update. Had this done automatically and car now starts much better from cold. Pinking slightly reduced but still very much there. Plus see below (cooling fan).
I expect worthwhile but haven't done yet...
1. Spacers on front engine cover to help keep engine drive belt cooler. I want this done asap, as it seems to help but not aware of any real data to support this. Can't cost much!
2. Cooling fan addition + associated ecu change. My driving is mostly in country or light town and have never had skipfire mode kick in. Hate the look of the cooling kit and prefer the fitment of a fan behind the engine (as many have done and Krazy Horse etc.) Looks really worthwhile in hot climates and for town driving. But ecu change also allegedly retards ignition and reduces power.
3. Stage 1 exhaust / air filter. There are several kits - the Morgan one, the Garage 56 one, the Krazy Horse one. All seem to add power, and reduce back-pressure and seem to reduce pinking without retarding the ignition. I am waiting to decide which one to have added to my car and want to avoid the cooling fan ecu change until then (at least). If a Stage 1 upgrade also allows the ignition to be advanced back this might be a great combination. In the meantime my car suffers pinking but engine feels strong, so I throttle back where necessary. Not doing track work in this car for lots of reasons...
4. Chassis upgrades. Awaiting information about what needs to be done, but at present there seems to be evidence that many earlier chassis crack. Don't think mine is cracked at present, and Morgan has always been good at dealing with this as far as I know, even out of warranty (as you would expect).
5. Compensator. I am on early compensator and after 4500 miles it has not been a problem. I don't think it has the grease nipple added but it isn't especially noisy. I am 'considerate' to it below 2500 rpm... Centa compensator sounds like a great upgrade and I would have it done if I had to have engine out.
6. bevel box. My bevel box is not too noisy and quietened down quite quickly during running in. After last factory information last October the lube has been changed and it appears to be a bit noisier but not dramatically so. Don't think the NVH bevel box mounting work appears necessary or even desirable.
7. Empire kit. Sounds great but I am happy with the Comfort kit at present.
8. Harley replacement rectifier. Seems a good option to reduce cost of change if yours fails. Mine is original after 4500 miles and seems fine.
9. For what it's worth I prefer the early rear gear lever positioning, but it seems this is horses for courses. The later position allows more elbow room.
10. Blockley front tyres. Seems a worthwhile change over the Avons but no personal experience. However, I will change to the Blockleys when I need to change my front tyres which will be at about 6 - 7000 miles based on existing wear (although with Comfort kit the tyre wear is allegedly much slower).
11. Cosmetic changes - as desired but I'm happy with my standard steering wheel etc. but did add internal leather side pockets from Allon White which I'm very pleased with, look good and more capacious than the Morgan items.
