Some observations:

The GEMS Plus 8s are problematic. Outside the early Overseas variant (1998-2000) I find them sluggish. Engine management parts and some key parts in other areas are VERY hard to find as Morgan kept using the system after it had become obsolete and no longer produced. The frotn cover wear suggests are conversion of ignition systems will be needed by all of them. Many LR owners have already done so. But they are newer so people pay more.,

[quote=MOG 615] 5 Do you live in an area infested by speed bumps , if so the early Roadster has VERY low ground clearance , and although the sump modification certainly helps , the clearance of the trad +8 is better.

Actually. The clearance is the same or worse. However, the sumps Morgan used do not shatter as they are made of steel. (They did not use the later LR allow sumps). Steel sumps merely dent. One takes them off and bangs them out with a 2x2 length of wood. I keep two, so I can swap them without losing mogging time, The best Plus 8 sumps are those used on the Hotwires. They are stronger, less complicated, offer more ground clearance and carry an extra litre of motor oil (the best oil for +8s is a natural oil and a bottle of ZDDP if you like cocktails) much cheaper and the only secret to Plus 8 engine longevity.). Oil changes should be done every 3000 miles or yearly whichever comes first. The less expensive oil m itgates the cost. Please do not use synthetic. No help whatsoever in the circumstances.

Yes! I believe I have seen his web foot prints on the gomog site from time to time. I also have some UK racing people I advise who use Techniques. Brian is very savvy.

Please note that racing people develop racing cars. The needs and setup for road going cars is very different.

P.S. The mighty American aftermarket made an inexpensive (45$) steel sump for the Roadster engine, albeit after some minor modification. Sadly, it was not published much in the Morgan community and the ones I saw were priced at a huge price after the modification.
P.P.S. Excellent thread
