Hi

I was wondering if thé k24a4 would maintain good fuel economy

I found this mechanic that would do thé swap for 4k$ in thé montreal area.

 

I have been getting around 28-30 mpg with a k24a2, you should see the same if not better from a k24a4, but i would not go with a a4 unless you plan to build it or turbo, the stock a4 makes less than a stock k20a2, if you want a good stock k24 motor, spend the extra money and get a k24a2, if you want good all motor power and good gas mileage, get a k24a4 block, put a k20 head on with 12.5 cr pistons, simple build and can make 240-260 easy
