First time poster, big howdy from southern California Desert! I have been thinking of getting a "slow" car that I could drive fast. After much debate, I have narrow down to the X1/9, with Miata as a backup alternative. As a former owner of 124 Spider, I have been liking X for decades, therefore it's my first choice. Ideally this is what I would like to have: Keep the original steel body. Must have A/C, it goes to 120F here in the summer, AC not debatable. Improve the output to have about 170 lb/ft of torque, and say 150hp. reason being that I do bi-weekly dash up California Hwy 74, from 100ft elevation to 5000 ft elevation in 15 miles. Almost a hill climb, torque rules. Excellent brake and handling. Weekend or occasional use car, not daily commuting device. Questions, quite random, sorry: Anyone know the weight of that 128 engine? or better still 128 engine + tranny. What's is largest tire/wheel that could fit without adding arches? or minimum arches? How to improve X's weight distribution? From factory, it's quite rear based, does that affect handling? I am eyeing new generation of 3 cylinder engines for it's light weight, and high output, anyone tried that? https://www.cnet.com/roadshow/news/new-ford-1-5-liter-engine-run-two-cylinders/ https://www.wardsauto.com/2015/2015-winner-mini-15l-turbocharged-dohc-3-cyl I heard that X has some sort of rear torque steer, true? What's the realistic minimum curb weight one can expect without gutting steel body, factory steel suspension, etc? Thanks guys for helping out! California Highway 74.
