I've spent the last couple of months researching various EJ16, EJ20 and EJ22 configs to see what would work best for the 1971 Volkswagen (type 3) Fastback I've been resto-modding. Ultimately I ended up picking EJ20 for availability and the CNC engine hanger and adapter that are readily available for the 2.0 but now need some help. NASIOC, here and a few other forums mentioned closed deck vs open deck, variations between US and JDM engine blocks, etc. etc. I'm not sold that I need the best of the best configuration since I won't be doing any power upgrades. desired specs: Stock output TMIC will be moved to to a BMIC as well as the radiator I'll be making a shorter intake manifold to clear the rear trunk lid I'd like to keep the stock ECU if possible or recommendations for an aftermarket ecu if that might be easier. Cheaper is better, i'll spend money where needed but this is just a runabout fun car.
