    Starting My Mini Up

15 years ago I ripped apart my 1992 1275 mini sprite, it’s a carb engine and I’m sorry to say in pretty bad shape!

Hopefully early next year I will be having the sills and doorstep replaced that should leave me with a solid shell to work from.

My question is, what’s my best plan of attack for rebuilding?

It’s a rolling shell, the engine although has not been in the car, turns over freely but the car has no wiring, breaks pipes etc etc.

I’m inclined to start with installing a whole new wiring harness to begin with, but also recognise that this really has little impact on getting the engine running, same could be said with the breaking system.

Just looking for advice from others that have been through this, any lessons learned or things you’d do differently.

Thanks in advance

My plan basically involves thinking it through and doing all the things that require easy access first then building up from there

So, shell first obviously and painting the underside and engine bay, painting enough of the inside that you can put in the pedal box, or all of the inside if that makes more sense at the time.

Then get the rack and subframes on, make it a rolling shell, get the brakes all fitted which also means suspension etc obviously. Just fit the ends of the drive shafts for now so the wheels can be bolted on

Once the inside is all painted i'll put the wiring in, fit all the lights and a battery or power supply to test them. You can loosely fit the switches or just use crocodile clip leads to test everything

Then I'll fit the tank and get the engine running, then when that's good and I know there's no more work to be done I'll do the bodywork and paint it

Personally I think just minimal interior stuff until the outer paint is done, probably fit the carpet and seats etc last but either way..

might be subject to some changes as I go along depending how it pans out but that's the general idea anyway

Interested to see what others come up with though and will bear those things in mind for mine

One point would be to fit the brake pipes and fuel line from front to back before anything else once the shell is solid.  Even then it may involve removing or at least partially dropping the subframes.

don’t do what I did… remember to install the fuel line pipe that runs behind the steering rack.

I fit pipes and battery cable to floor.
steering rack, then subframes.

Pedal box ideally should go in before any of the interior, remember to fit the carpet before fitting the heater.


I generally get the whole car built then once it's built I run the engine, treat any long term lay up like a fresh engine.
