NEW 96 97 FORD ASPIRE 1.3L COMPLETE ENGINE ASSEMBLY

[Allch Chcar]

The Aspire had a Korean engine for one generation so it would be a gamble until you knew that it was the Mazda version, plus if I remember correctly it was always a cast iron block. The Korean engine has no aftermarket that I am aware of, and in this case you would want the Mazda variant which is just a smaller version of their 4 cylinder engine family at the time.

It's true that the KA and even the SR are heavy engines so I don't doubt it could be light. The problem would be sourcing a cheap Yaris engine.

I'd like to get a 240sx hatch and put a Suzuki engine init because they're both light and small displacements. And then I'd built an engine for E85 but keep it a street car. I spent some time researching the G family hence why I brought it up. But right now I just need a car so I can get a job away from home. Someday I'll get around to it .

Those 2.0 liter Ford Z techs might be neat. I think they use many of them in the UK's cottage industry. In a car that light it would be a rocket. Is it one of those Caterham cars ?

Lampredi Twin Cam 4 cylinder ( Fiat, Alfa, Lancia ). Best designed 4 cylinder in the universe, heck, everybody copied it. Bombproof, rally winner, simple, easy to get parts for, not that expensive, spins in the right direction. Put some compression into it and keep the cam timing near stock, should mpg well.
