Lotus Elan

Most satisfying long term upgrade

PostPost by: JJDraper » Fri Jul 28, 2017 12:09 pm

Looking back now, I realise I have spent far too much on my +2 for a cost/benefit calculation to make any logical sense, however, there are a few things I have bought or done which have been deeply satisfying.

A short list:

Magnecor red dizzy cap & leads - bought at Stoneleigh from QED for 60 quid in 2003. Seemed a huge price, but has just worked & makes me feel good.

Wipac plastic headlight units (for land rover Defender I believe @ 30 quid for the pair in 2009) and Osram nightbreaker H4 bulbs - precise beam pattern and best head lights of all my modern car - who needs xenons. No bulb failures since fitted 30k miles ago.

Millers 20-60 CSS fully synthetic oil. Makes those long tours in hot countries worry free.

Weber head refurb by QED workshop in 2003 - full rebuild including guides, valves and new cams. Expensive at the time at nearly 1300 quid, but time has proved the spend as worth it. The valves, guides and cams are still in service after 100K miles, albeit with a clean up & check when head gasket has been changed.

So what has made other owners quietly satisfied over the years with something that has just worked?

I got an Orange tire pressure monitoring system (TPMS). The plan was to have a safety margin and run without a spare tire. That eliminates some weight and gives us a bit more room for luggage. It works great and reads temp or pressure or both. All good. But here's the deal - when the sensors were installed, last fall!, the tires were filled with nitrogen. I've put about 3k miles on them since then and the pressures are exactly the same now as when they were mounted! Perhaps the moon and stars were lined up that day, but I just got another set of sensors for some performance tires and they are going ro be filled with nitrogen too.

Top of the list: CV Joint driveshafts. Purists please forgive me, but I think they greatly improve the car.
Second: 3.54 diff. I think it makes the car much more usable on today's roads (despite my diff tribulations...) .
Third: New dash. Satisfying to look at every time.

Agree with CV drive shafts.
Next for me is EFI and wasted spark.
Again, purists please forgive.
Electric headlamp lift is also a pleasure, it used to annoy me intensly to find the headlamp pods half up after the car had been sitting for a while. This of course doesn't effect the pre fail-safe cars.

High torque starter. After a several episodes of stripped pinion gears and faulty electrics on three different Lucas units, I fitted an upgraded starter some 34 years ago, never an issue since.

My best would be the Emerald. Not going to win the pound for pound contest tho.
Next would be the Sue Miller drive shafts, incidently not failed me at all.
3.54 Diff as it keeps revs down a little.
All these combine to a fantastic drive.
Kick the tyres and light them fires...!!!!!!!

TTR manifold and full system for up to 150BHP. It felt like an extra 10% at the top end, it sounds great and looks great. Have now had the manifold ceramic coated which has greatly reduced the under bonnet temp.

I had a replica of the standard big/wide Elan radiator made in alloy. Never overheated or got close since.
