I'd love to do this conversion but with some big ass 40mm bike carbs and a bespoke set of headers. Mitsubishi did do an old school twin cam engine on PHH carbs but not only are they rare but damned hard to fix if you are unfortunate enough to had a mechanical problem. Don't even mention the HKS aftermarket head unless you have bottomless pockets... Keep us up to date on he swap
Hi again geezer! Yes! though i'd been around engines almost all my life, this one is totally new for me, so i intend to gather all the info i can before starting and be really thorough when putting toghether all the parts, specially the timing belt! Thanks for the heads up!
My father has some 45-45 dcoe weber carbs to put in, so i think i'm going to ask him to lend me a pair to fire the engine up at first, but the goal is to upgrade to fuel injection in one 2nd stage. I want to put a turbo in so i think that an injection managing is more simple and reliable than a carburetor. Love carbs though, specially that ones cause they have a lot of history in his days as drag racing tuner.
Mi younger brother is a freaking awesome mechanical engineer (all the brain-gen of the family went there), he is in the railroad business and made some really successfull repowering work on several locomotives. Several night ago we talked about the idea of designing our own ecu. Hahaha that is gonna take some serious time though!!! if we ever manage to achieve it, is a really ambiciuos project but this is for having fun, so, is there a better way than to do it with your little bro? i don't think so.
I didn't know about this dohc carb fueled head from old mitsubishis that you mention, but here the parts are really hard to find! (1 year to find this head, so picture that) i see YouTube vids about guys who buy this head for just 49 bucks, and here that is insanelly unreal, i was asked to pay 500 for a peeled block, wtf? but looking and searching things eventually appear, so... i have to be patient.
Thanks again for the good vibes and all the info. you're the best!
Cheers!
