The car in pic is mine. I have had many different ka motors in the car. it would run 14.0 at 99 with broken motor mount. it had 45mm webers, nissan comp manifold. Once i put a header, mild cam, and solid lifters it ran 13.4. Then i built a 12 valve with slightly bigger cam and more compression. Ran 12.4. The stock ka24de in the 1200 with 45mm carbs I was running 13.4. I think i will be doing a ca18det now. I want to take some weight out of the front end. The carbs on the ka motors probably made more power but i really think with stock efi tuned the car would have been faster.
