i think you can probably get close.
It costs $ though.
My B21ft, with a mild tune running 14.5AFRs on the way home, did 30mpg on my two hour all-highway drive from college to home. Thats a b21ft. 7.5:1 and a big dumb turbo that I liked to roll-in on, and a k-cam.
It has 373 gears, the 3.35 t5, and megasquirt. Now do I think you can get to 40? No.
But if it had the ever-illusive 3.31 gears or the 2.95 t5 with the lower 5th gear... and a high-comp b230, I think you can get low-mid 30s out of it. I hope to find out shortly what my 10.2ish:1 b230f+t will get me. Im hoping for the 32 mark with the same drivetrain.
