Hi All,
I bought a 1997 mini cooper 1.3i in September and am having lots of fun playing with it to get it the way i want it. I have my new rear subframe and a full sports ride kit coming next week I am so excited!!!!
The probelem I am having is that after this is done and the interior is ripped out and replaced I want to get on to some engine mods but don't know whther I have an MPI or SPI as I have been told that they changed over in 1997!
Could anyone let me know how I can tell which one it is as I don't want to buy the wrong parts when fettling the engine.
Any help would be appreciated cheers.

I don't know if there was a period in 1997 where cars were fitted with a mix of SPi and MPi parts, but the MPi's got quite a few "upgrades". Twin speed heater is the most obvious I can think of.

If the radiators infront on the engine its an Mpi, if its at the side of the engine, then it'll be an Spi

Ipod yours is without a doubt an MPI
1996 was the change over from SPI to MPI so chances are that yours is an MPI, the radiator is the biggest give away, if its unmodified layout and your radiator is on the front it is an MPI, but if its on the side, chances are its SPI, but apparantly, i dont know how true it is, but some of the very first MPIs had side mounted rads, so the other way to tell is if you have a coil, if you have a coil it is spi, if you have a coil pack, i.e a square lump with your HT leads coming of them then its an MPI, if its a traditional round coil feeding the distributer which then fires the HT leads, then it is SPI, surefire way to tell is to take the air filter cover off and have a look to see if you have a single injector its SPI, if theres 2 then its MPI

I thought all MPi's had a twin speed heater. Was it not one of the plus's to buying an MPi.
As for the upgrades. yes there are lots to be done, but just watch as some are expensive
What you doing with the interiour? and what colour is it?

Apparantly there are some Jap export MPI's with side mount rads that are finding their way back to the UK.
The absolutes would be SPI - dizzy, MPI-coil pack. The MPI also has a different block casting that the oil filter screws directly on to, next to the clutch housing.
