bro kumar,
1st of all, endorsement to 2.0 is not legal for all wira satria putra, only perdana body can be 2.0 not even powerfull cable can done it right now. if u dont care about it and in certain amount of budget just go for RVR halfcut. As i know most of the spec is as equal as evo2, only its auto tranny, so most of the part is compatible to install to your chassis, only the upper mount small inter-cooler that need to transfer to front mount. Then its can run inside your hood already. Its will be a lot of hassle if you get evo3 halfcut then as you said u want to be its auto, then u also need rvr gearbox also to fit to its.... a lot of hassle..
If u really dont care about budget, get evo 7.5 gta, malaysia boleh marr... any engine can fit to ur putra, if not mistaken its cost around 30k++ for 7.5 gta halfcut.... correct me if im wrong...
