I put it on a Suzuki but then I had some tuning issues - best described as a fail on my part. I never was able to duplicate the economy improvements on the EFI engine due to lowered engine temperatures. I injected too much cold water and blew the Head-Gasket. My enthusiasm declined after that although I do have reflections on how I could have done better.

No, but I get where you're going with that -

but the bodykits that are available for them in Japan make them look so fast.
2003 Renault Scenic - 30% more power with no loss in fuel economy.
1991 Toyota GT4 - more economical before ST215W engine-swap.
previous: Water-Injected Mitsubishi ~33% improved.
future - probably a Prius
