Actually I heard before that it's illegal because, as with most 2-litre Wira conversions, the chassis will be compromised with a 4WD conversion.
Most 4WD conversion involving cutting off the entire rear-half's floor, leaving only the main stress member (the centre tunnel and sides).
The halfcut's rear floorpan (with rear arm mounts, diff mounts, etc.) will then be welded back onto the car's monocoque.
If you do that type of modification, of course la Puspakom will be reluctant to pass your car. How can they test to confirm if the floorpan welds are strong enough? How are you sure that the welds are strong and will not crack? It's not a simple Mig weld job we're talking about here.. you really need those high-powered spot welders. How many mechanics are competent enough to do this sort of job?
