Doing the GT-4 Conversion, Should I? Options

[94CELICAGT_98584]

Okay I have a 1994 Toyota Celica GT with the stock 5SFE motor in it. IF you check out my pics you will see I have all the Gt-Four body parts. What I want to do is do the 3SGTE swap. Not just the 2nd Gen 3SGTE swap but the 3rd Gen. Then I want to get the rear end for the GT-Four and have it installed. I have been talking to an MR2 Shop near me here and they have found me a 3rd Gen motor out of a Celica in Japan. The guy is currently putting together a quote but he is thinking about 5500 for the motor/installation. The car I have has a ton of miles on it but it looks great. It currently run great just leaks a ton of oil, and all the electronics and everything works great as well. I guess what I am asking is if I should do this or not. I'm thinking after I get the motor in for 5500 the rear end will cost another 1000 then I want to custom paint the interior and get new seats which I think will cost around 1000 then get a few dents pulled and fixed and finally get new rims and tires. All in all I believe I will have around 10-12 Grand into it. Is it worth that much to have an almost one of a kind car in the US. I know that there are a few others that have done the whole conversion but I have never seen one before. Just looking for some advice. Thanks
