Ok guys,I've thought long and hard and I have these options:
1-Do a 20V BT swap,which I'm beginning to dought if it will fit in the engine bay cuz of many ppl saying it won't :s,but this is my 1st choice and I want advice from the senior members on this.
2-Do a Z-GEN engine swap(1NZ-FE,3ZZ-FE,1ZZ-FE OR 2ZZ-GE).
3-Mod Vitz's 1SZ-FE with NA mods and maybe install a Wet shot NoS kit.
