A nice G13B is certainly the ideal solution. The main reason I'm reluctant to try that is that I know my daily driver would be out of commission for weeks while I worked my way through a swap.
Also, is a switch from automatic to manual transmission incredibly difficult? I know that my idea of 'difficult' is a lot different from some of the forum-goers who can apparently do automotive magic. I'm confident that I can get through most projects as a matter of time--I've got a good knowledge of how they work and some connections, just never torn a car apart before.
If not a manual, are there automatic DOHCs around? I must admit that even after lurking here for a month or two, I'm not sure if there is such a thing as an auto GTi.
