Well I am overhauling my gearbox but I know I might as well overhaul the engine as well. The engine is a 1994 auto, it has done roughly 90000KM. So what parts do I need to do the overhauling?

Minis wear the bores oval over time so just throwing in rings and bearings and the like is a waste of time. You do need to take the engine to a specialist engine reconditioning machine shop. They will do all the measurements and the machining.

Pistons (with rings) are fairly cheap these days and they come in many different grades of quality. The machine place should then give you the option of sourcing them yourself or them just supplying them.

Look at about a thousand dollars for a reco'ed sub assembled block. Extras like balancing and performance stuff is going to cost more.

The cylinder is also probably going to need work and its a good time to get hardened valve seats (exhaust) so you can use unleaded fuel without damaging the valves and seats. Add about four hundred dollars.

Mini engines have two main archilies heels - oval bore wear and worn valve guides. Do it properly and do it once and you will have an engine that will happily spin for another 100,00o kms.

If you don't live in Sydney find a good mate who has an account with a courier company - only cost me $35 to get my motor in two boxes from Bris to GR using my son's Horseland Account with Startrack
