First ever post on a forum!

Owner of -
1989 EC9 1.4 Dual Carb Irish
1991 EF2 1.3 Single Carb Jap
Spare Engine/Gearbox from 96 Spec DC2 UK
I'm about to swap the B18c6 into the EC9 and using EF2 for Jap bodywork/spares.spare
I'm looking for people with experience and advice on the conversion (Mounts, shafts, looms, etc.)
I want to have all parts, information and knowledge ready to go so I can complete the job in a couple of days.

Engine clearance?
Best mounts?
Gear linkages?
Cable to Hydro clutch?
Driveshafts? Want to stay 4x100
Looms, distributor, etc? Have the ECU
Interior wiring, getting clicks working (rpm, Speedo, etc)
Fuel system Inline walboro fuel pump?
Any problems to prepare for?
Also rear disc conversion (again I want to stay 4x100)

All advice welcome.
Thanks
