Pretty cool, sounds a lot deeper than my 1.6 with a 2" exhaust & turbo muffler. What are you running for a muffler/exhaust?
On the 1st vid, there's a tick or rattle noise going on that increases with RPM. Is it the timing chain noise? Normal, or...?
If ever I was to go as far as an engine swap, the 2.0l l4 would be my choice, but I'm not very familiar with them... yet.
Neat work!
