We have an owner of one such beast in A2oc--he had it converted a few years back and its an incredible machine but it struggles to get the power down even though he has now put a trick quaif differential in it----there is a video of it on you tube ill try and find it. Malcolm built it as a result of the original 1.4 petrol engine suffering a seized camshaft. The engine compartment is tight with the 225 tt 1.8t engine and turbo pipework--it was even a nasty job to swap plugs as one was hidden under the windscreen requiring the engine yo be released from the mounts to get at it !
