Coz essentially it involves cutting out and rewelding the rear floorpan.
1. the right way of converting one is to actually to drill out all existing joints and rivets and remove the entire stock floorpan(which extends from somewhere on the rear seats to the entire boot floor section including the spare tyre wheel well which means when the floorpan is removed.. all you see is this massive hole in your entire rear section).
2. Then either purchase a evo 1-3/ GSR rear cut and then removing the same floorpan from that rear or try to source the rear floorpan from MMC in japan (last i read they were doing a stock clearout and was selling the floorpan at 1k aus each brand new. this was i think a year ago).
3.Then you reweld the floorpan to your existing car and tadaa.. you now have all the proper mountings for the rear diff, driveshaft, AWD fuel tank + exhaust. At this point you can also reweld any other joints in your car to proper evo standards as well.
Thats essentially a basic rundown of what you need to do. There might be a few steps i am not aware of as this is my deduction from the conversions on evocoupe.net
the common malaysian workshop way of doing it is to cut JUST the AWD mount section on the rear floorpan and also cutting the same area off your rear floorpan and then rewelding the new ketul of metal back on. Obviously this not only reduces the integrity towards the car's structure.. but depending on application.. the welds might just crack under pressure.
This is why AWD conversions is banned in malaysia. Ozzie land u first have to seek the advice and permission from a certified Road Transport Authority engineer where you will present your ideas, plans, or modifications and the methods you are going to take to get it done. The engineer would then deduce if you have met all conditions and steps to make the car roadworthy when its completed. If not he will advise you on the procedures that are needed and the extra factors that are involved. At this point only you can actually start work on the car. And once its finished... off to the engineer again to get it inspected and certified for roadworthy.
Its really a tedious process and really require loads of determination to do (also deep pockets if you dont know how to DIY most of the stuff).
My plan is to either start doing this when i attain my degree and get a proper job here. The thought of a 2 door Evo makes me high esp when its unique in a sense that its not a factory option at all.
I think i might have got most of the major points on the conversion right otherwise correct me if i'm wrong.
Cheers
