Uh, the Mazda rotary is an internal combustion engine. I think you meant to say it will never replace the reciprocating-piston engine. I doubt if anyone expected that ... when you have two good products, one doesn't necessarily replace the other. People like choice.

I'd order a full-on A12 from Pitroad, bored and stroked. But with a milder cam than they usually fit, to go with a turbocharger. EFI of course for the ultimate smoothness.

Generally speaking, US A12s have the distributor under #1 spark plug, while A12As have the distributor under #3 spark plug. But this is not the ultimately identifier, as the engine could have been an import (there were additional types of A12s for other countries).

The serial number is the real key. Does anyone know what year or model this number matches?

I saw a Corolla EFI tank bolted in the back of a 1200 coupe (inside the car). He did it to get the in-tank fuel pump and baffling.

At first I wondered how safe that was, but then thought about all the older cars that had a similar setup from the factory, for example, the 1200 sedan has it right behind the back seat.

Charlotte, thanks for posting this notice. Your web site is one the coolest Datsun/Nissan sites!

You mean the H165, right?

Shipping from US to AU is very easy to do.

And not as expensive as you might think either. We have several choices, including Fedex, US Postal Service and others. You can calculate postage yourself at http://www.usps.com.

Yes, I had a 1984 Chevy Impala 5.7 liter that got 12mpg. The other one was a 1974 Lincoln Continental with (stock) 7.5 liter engine which got worse, like 10mpg. I doubt if a stock 20B guzzled that much fuel.

Quote:Are you saying you'd rather have a slower, more economical car than a faster more thirsty one? If those are the two choices, I'll take the extra performance and pay for the fuel. I've had cars that get less than 12 mpg (what's that? about 4.8 km/liter, I think) and it was no big deal (wasn't a rotary either, just detroit V8 iron in heavy cars).
