I think Outbacks are sweet, but I have no idea how to answer any of your questions!

I do know there are plenty of swapped Outbacks out there if you are going the turbo route, so you may find that to be an easier and more reliable solution than a rebuilt engine with an aftermarket turbo kit. A very good friend of mine had an EJ20 swap in his.

You may also want to check out LegacyGT.com. They have plenty of love for all things Leggy over there.

Most importantly of all, get your post count up and show us some pics!

DOHC motors tend to blow headgaskets with even greater frequency than the SOHC ones, which have had plenty of issues with that in their own right. In the long run, a reliable swap is probably your best option. It will make plenty of reliable power over a period of many years and will be easy to maintain with readily available parts.

Of course, this is conventional wisdom. By all means, do what you want to do above all else. There are guys on here running N/A or with homebrew superchargers. There are spare parts turbo kits, aftermarket turbo kits like Forced Air Technologies and AVO, and there are all kinds of crazy Frankenstein swaps with EJ20's, EJ22's and EJ25's. There are even a couple H6 swaps floating around. If your goal is to be creative, then by all means turbo your EJ25D. But if cost is your concern, the small amount of cash you save in going with a homemade kit is more than likely going to be spent in maintaining (or replacing) the finished product.
