It has been done, many times I am sure. There are many options available, personally, id yank the engine, have the bottom end rebuilt and do a VG33 head swap, better performance with the same wiring and injection system, no mods necessary other than the head upgrade. There are affordable rebuild kits out there and with a bit of machine on the bottom end along with the cylinder head upgrade, you'll be golden. Sent from my LG-H700 using Tapatalk
