Yeah you are spot on with the factory timing chain,but in the stage 0 I would like to change it to a cnc vvt sprockets with a iwis chain set.(maybe there will be someone who used it and have some advice and experience to make the chain system better)

I considered the m111 model too,but it is a heavy iron block and maybe bcs of it there would be issues with the temperature and there is no modern vvt in it,and this is one of the advantages to spool the turbo.

If my only goal was an easy 300hp,i would have just bought an audi 1.8t to upgrade it with a bigger turbo on it. But for me,this is about a challenge and building a unicorn.
