Assuming this is in the correct forum, I would like in future to build a Manta A with a TDI - new technology in classic body. I have read about the new Opel engines that will be coming out (twin turbo Ecotec 212 hp anyone?), as well as the current line of engines, so are there any suggestions re. a checklist for mods? I plan for the car to be visually stock outside with all mods under the skin. I am looking for places to start and any ideas / suggestions etc.
