ok thanks guys, on the brakes side I have gone for a 109 setup ie 11 inch front drums, twin leading shoes and a split stsyem with servo also from a later 109, i know from testing that a well setup and adjusted drum system is every bit as efficient as disks untill the heat starts to rise beyond what most people would call normal use, should the drums prove adequate then i will leave them alone but if im not happy then i will look at a disk conversion, i wont mess about on this as brakes are vital but i think the 109 brakes will be fine on the lighter 88.
Im going to fit the petrol for now as I have been advised by the mechanic that will be doing the mot to keep it as per v5 log book as it has not been on the road for the last 8 years, then after the mot to convert to the 19J and update dvla before the next mot.
as a note, Has anybody noticed how closely the two engine blocks are in looks, i would even go on to say they look exactly the same with the various openings being used to drive different units ie on the petrol its the distributor where as on the diesel its the vacuum pump etc etc. the diesel is much heavier tho. can anyone shed any light on this, do they share the same crank, cam, clutch, starter etc.
again very many thanks for your advice / input.
Drew.
