Not sure what engine I want in my new build but My brother has a rotting 1.6 mx-5 uk spec on a G plate on his drive, its' done high mileage but is free to me if I want any of it.

What if anything could I use. I don't intent to buy a complete sierra donor rather amass the right bits over time.

Was thinking the engine and gearbox as it will be non cat IVA and have a feeling the ecu and inlet will be an easy swap into the haynes.
Drive it for a bit and either upgrade to a 1.8 mx-5 engine or go zetec etc.

is the gearbox a similar size to the the type 9? Anyone used a mx5 steering column. I'll proberbly keep the back end sierra and the front uprigts to keep things simple.
