@supraman, i have done my eliminatory, i am running a car with swapped engine. i have the idea of expected issues in engine swap. Now i need to know about turbo engine swapping, i want to know if anyone is running stock 4EFTE (135HP) in khyber, how this car is going to perform, cuz i m getting very good performance with G15A (97HP) engine. I have gone through different forum, ppl are upgrading their turbos to gain some extra HPs, so now i need to know whether i should first go for stock 4EFTE and upgrade turbo later or should install engine with upgraded turbo (without sacrificing AC)
