I have Diesel Corolla 1996.Its original diesel.Want to change engine in it to switch to CNG.Intnd to use the car mostly for local use in Rawalpindi.But may be sometimes for long route travel or may be more frequently if the engine swap is succeeded and is then reliable enough not to give problems on M1.
Which engine is going to be a better option?2E,5A-FE or some other?Help needed
