Anyone who installs a Japanese engine in a German car will burn in hell forever. Or at the very least, develop an annoying rash in an inaccessible place.
Bummer, I thought Subie was Swedish or something....I don't have an issue with making the 914 modern, more powerful, and continue to make a 40 year old car contemporary.
That said...I do have a little reserve with the mix...German engineering and Japanese are very different...this make no difference to the Subie conversion though, just the thought of standard German 13/15/17mm bolts being mixed with the light weight 12/14mm bolts on Asian cars.
bottom line...do what ever, but don't put a fart can muffler on it!!!!
