On the drive home from getting the TDI, It was 8PM for 73 miles on the freeway which meant the speed of traffic was about 85MPH. I got an actual 51MPG in the TDI, this is completely stock and somewhat maintinence deprived.
The RPM in my TDI at 85 is about 3K, in the Rx7 it would be about 4K.
The Rx7 for this same drive would get 25MPG, and I have tuned it to be as economical as possible, running opem loop off a wideband with a maped target value. At freway load at that speed it runs about 18-1.
I will aplaud you when you finish your project, but I still think you should go for a larger merc diesel instead.
Hell for about 5K you can get a merc CDI and trans, have a drive train thats matched and desined for RWD, you could have the power and torque with a chip to put an FD to shame and still get 45-50 MPG.
You could have it all.

I drive at 60 mph to work. I like the way the rx7 feels.I cant describe it but it just feels good. It aint pretty but I like it. I dont know if going 80 in a Jetta will give good mpg numbers either. When I drive my 5.9 cummins powered dodge I get 20 mpg if I set the cruise at 58 mph. As I stated I'm in no rush when going to work. Besides I want to be the first to convert a Rx7 to diesel. Where would the fun be in buying a jetta?
BTW, my 1.9 TD arrives today

I'm sorry to tell you that you won't be the first to convert an Rx to diesel.. There is a 1g with a big cummins diesel.
Also radial as this sounds, a plain old 12A will start and run on diesel. I did it with my old 85 model when I ran out of gas at a rest stop. It didn't run well but it got me 40 or so miles to a gas station.
