agree with AlBundy above.
my entry level UDM was a M43 and it's till running strong now (belongs to a fellow member here). Same thoughts I shared, but it's not always about power.
It gave me the experience no other brand did - driving pleasure.
Enjoy your ride now, until you have bigger budget then go for IL6 - no point stressing out on a transplant project that can always comes with headaches.
I learn from here : there's no replacement for displacement.
