Fran,
I know I am a bit late to the party, but would like to thank you for this awesome project! As a hard core Mitsu guy, I just couldn’t get excited about Factory Five’s 818 project (even though, they are local to me). But I loved the idea of Japanese turbo four based kit car. Your car answers any reservations I might have had with the 818! Great choice!
And do not get bogged down in 4G63 building/tuning discussion. Making cheap, reliable power from this engine is trivial between 300-700hp. Going much above 700hp starts to get tricky, but so few people need or want that much power, that it isn’t even worth discussing (not here, anyway, there are plenty of DSM forums for that).
I am eagerly waiting for any updates!
