if its resale value you're after, the decision has already been made. the type R is the way to go. if you're after something fun and still reasonably cheap then stick with the EG. Like you said, you've already sunk a bit of money into it.
the sad truth cars very rarely make money. all modders have come to terms with that.
Just to make things more difficult. My mate got a type r coversion priced up by a workshop in perth. 10k for front cut, conversion, extractors, exhaust and some minor brake work. i think he was talking some coilovers too.
