That's my personal goal. I wanna do 35 mpg highway in my B2200.
Maybe it's an overly ambitious goal, but I figure "reach for the stars ... and I might at least make it into Earth orbit!"

Not only do I want 35 mpg, I want it with a gas engine!

I think everybody will agree it isn't gonna happen with the F2 engine, not even with fuel injection, and it probably won't happen with the FE engine, and even going to a Kia Sportage DOHC engine probably won't net 35.
Any of these engines, properly built, can make nice power in a B2200, but 35 ain't easy for a truck!

So, I'm thinking bout making the best if my 8 valve F2 for a time, do a full rebuild, deck the block for higher compression, and install a header to compliment my new Weber carb - while I find and buy a 1986 or older Toyota Corolla for it's 1.6 liter 4A engine, and its rear wheel drive five speed transmission.
How hard could it be to engineer this little drivetrain into my Mazda? It would be easy! And it'd give me many advantages. Old Corolla's got around 30 mpg, and newer ones do much better! The older Corolla's are a dime a dozen, and performance parts are readily available. And - once I've installed the rwd 4A drivetrain, I could then use any front drive 4A engine, up to 1998 I think, going from 8 valve with carb, to dual overhead cam with EFI! Surely this will get me in the 35 ballpark! And I'd still be driving my pickup! (Morphadite pickup, but still a pickup!)
