Thank you all for your prompt responses, much appreciated.
Was considering the K6 turbo with auto for the simple reason that is easily available here, with wire harness ECU, tcm and since it's a van engine, it's ready for that 45degree angle fit.
Looking at the specs, theoretically, it's more powerful than my current F8 and Omni weighs less so power to weight ratio should also be better.
Again, theoretically.
Will give all an idea of my van.
Made custom 3 inch lift kit with camber adjustment so now she rides on 175/70 R13 wheels without rubbing.
Power windows , central locking, EPS off a Suzuki every, hang on AC etc.
Would anyone be able to tell me if the F8D, from the current alto 800 would fit on my bell housing, again, an easier engine to find.
Thanks for all the advice
