hello Some may be aware fromprevious threads of mine that I have been looking a possible ways of getting a little more grunt out of a 1.8L petrol T4 transporter - also converted to LPG. A head change was one suggestion and seems a quite cost effective way forward as heads seem to be quite easily obtainable at relatively low cost. Fitting is a different issue I agree! Just wondering if any one has done a similar project on a standard 1.8L. I know of someone who did a similar project on a 2.0L transporter (AAC fuel injected engine) and suffered with overfuelling when running on petrol - fine on LPG.
