Hi folks, I posted this in the 70-series forum yesterday and it was recommended that I post it in the diesel forum as well. I'd sincerely appreciate some engine advice for an Aussie-market HJ75 Troopie. It's a 1985 HJ75 that was used for railroad testing in and around Wyoming. (I took the Hi-Rail gear off long ago.) 90% of the mileage was on rails in 5th gear. (God only knows the idle time, though...) I've been sitting on this vehicle for about 16 years now, always hoping for the time to do a body-off restoration. The time has finally almost come. The factory 2H is a little weak on oil pressure, and really gutless in the mountains. I'd originally considered rebuilding it and fitting an aftermarket turbo kit, but I had a really bad experience with a 2F rebuild I had done in Wyoming a few years ago. I'm considering a JDM engine/transmission package, thinking the 12H-T is the way to go. From what I "think" I read years ago, it's a straightforward transplant. I built a 302 Ford powered FJ40 twenty years ago, and hope the 2H to 12H-T swap won't need as much creativity. I'd like to think I could have all my original gauges working, etc. I know the 12H-T is a strong, reliable engine, with a big following in the markets that get it. Can anyone comment on the practicality of the 12H-T swap, or recommend something better? Thanks in advance for any advice!
