If you're after ultimate performance, then LPG will of course get you around the emissions problem, providing you have certified the system and notified the change to the DVLA, otherwise the computerised MOT system will test it on petrol, as the car left the factory. However, not all automobile engines are suitable for use with LPG as a fuel. LPG provides less upper cylinder lubrication than petrol or diesel, so LPG-fueled engines are more prone to valve wear if they are not suitably modified. Personally, if I were to go the 4 cylinder route for performance in a ZT, I would find an N Series unit out of an MG6, get the head ported and polished and then get the Z&F 204 BHP tune put into it, which I would think is probably enough for a 1.8 engine designed in the late Eighties. However, I await your developments with interest.
