Youd be wasting your time, you need to talk to the guy face to face, with language and accents you'd struggle on the phone and hes very busy......hes in Sharjha- 15mins form Dubai,Liberty Motor Sports, youll find then on the net. Basically everything was rewired from the new engine linking into the existing system for the rest of the car, this is what took the time.....

good luck...

No big deal really, it fits....yes you are right the oil pan needed to be changed...as do the engine mounts...and other things but not a major deal....

Let me guide you through the swap. Sell the 2006, then buy an Alpha H3 = done, swap complete.
