Hey Fahad, I recognized you from your avatar! You used to be regular on the offroadpakistan group, what happened? You went from the Ford GPW to a 2JZGTE powered Mark II?? Wow that's a jump! I have the same engine, just non-VVTi, waiting to be installed in my CJ7. If I'd known you were selling I wouldn't have already bought that one. I wouldn't advise replacing the engine at all, just drive it responsibly and sensibly. You'll be spending money to downgrade... not a wise idea. But if you absolutely MUST, I suggest you simply go with a 2JZ-GE. It's the naturally aspirated version of the same engine and it will bolt right up. PM me your mobile number, I'll give you a call.
