I started my project this summer by designing and making a new exhaust from the catalytic converter onwards.
Then I read the article on these m111 engines by @Alex.M-oneeleven and opened pandoras box.
Remembering that I had bought a pulley mos for the crank years ago. Installed that and I was very pleased with the result. Also fitted Denso iridium spark plugs. Now I am in the middle of this project with the just installed larger intercooler. Went for a test drive yesterday evening and it seems that the ecu is now cutting the engine on high revs. I was warned about this and I will try a new fuel pressure regulator next. I found one for an RS6 audi and got it on monday. I will try to post more on my mods here.
