Default Replacing longblock...suggestions

My 2002 wrx had a blown head gasket and a popped radiator. Long story short, I took it to a mechanic who did more damage than good; proving the old adage, if you want it done right, do it yourself. I would like to see some improvement in power, if I am going to be that far into the car.

Time and the budget are tight. I see no point in swapping in a worn out USDM engine for the same price as a JDM engine with half the miles. I am looking to do the job with $2k to $2.5. I will be doing all of the work except for any tuning, unless there is a simple and inexpensive way for me to do that. If it is going to take me several days or weeks of intensive studying to get the job done, that part will need to be done by someone else.

From what I have read, my choices are 99 to 2004 ej205 or ej207. I saw somewhere that an ej207 v5 could be used as a longblock. I am assuming anything before 2001 will need to have the intake manifold, cam gear and harmonic balancer transferred from the old engine. I plan on using the USDM ecu. I was just going to leave the avcs disconnected (if it has avcs). There was a 97 sti engine and transmission I found in the price range, but I am guessing I can't use it as a longblock without rewiring the whole car.

I am not looking to build a rocket. Its a dd, so quicker spool or low end torque would probably be the grin factor I am looking for.

The questions are:
Will a 97 sti engine work as a longblock with a fresh tune?
Would I be better off with a JDM ej205 (99 to 2004) with $600 exhaust, a different turbo and an intake?
Where can I go for a tune? I am 2 hours from Chicago and 1 hour from Indy.

Sorry about the novel. I am looking to get a more focused direction on this, as I need to hurry up and get this done.

Save your money and buy a newer ej207 with the jdm ecu.using the older engines turn into a breaches. Also you could do hybrid with your heads and a 2.5 shortblock. You will gain torque and if you do your heads right then it will be a nice combo

I would like to have a v7, but I need to do something now and without an ecu I'm looking at $3k minimum. If it doesn't get fixed in the next 2 to 3 weeks, I will have to get rid of the wrx and drive something not so fun.(Not happening!)

I read where someone swapped a v6 longblock and stripped the the intake, accessories, etc. He said it was pretty much a direct swap + a tune. Since anything jdm will be higher compression, I will have to get a tune anyway. I was 3 hours too late getting the v6 I saw the other day, so I am waiting a couple of days.

If I don't do the older sti, I will end up putting in a jdm ej205. I think the 60 to 100k less miles will make my life easier in the future. That way I can at least get the right year. There should be enough left for some minor mods.

The hybrid sounds more like something I would do to the engine that isn't in the car. From what I can tell from the mountains of threads, its all in the heads. I can tell you right now, I will not have the time to get the heads done. Not because that is how long it takes, but because I will spend the next month reading and second guessing myself, while looking for perfection on the first attempt.
