2jz E30 swap questions for a newbie

New to the forum, not cars. Done a couple Subaru swaps, RSTi build, WRX build & 2 rallycross builds. I'm wanting to start another project. I want something scary & fun that I wont be able to keep straight. I've always loved E30's & I've always loved 2JZ's. I'm considering selling my WRX to fund this project. I could probably get around $8500 for my WRX. Is this a pretty solid budget for this kind of build?

-I found several E30's on craigslist near me for around $1k-$2k.

-eGay or maybe another engine importer would be the source for a 2JZ/tranny.

-My Dad & I own a little auto shop with a hoist & every tool you could need so that's no problem.

-Wiring - one of my 2 concerns. How does this work? For my RSTi, I had my RS harness merged to my STi harness. Do they make kits? Plug & play??

-Tuning - my other concern. I've always had a local come tune my Subaru's. What are my options as far as tuning the engine goes?

-With tuning, I'd like to run single turbo, injectors, fuel pump, exhaust, intake

-I'm located near Fort Wayne Indiana if that helps any

I've done some good researching over the past couple of days & found some good info but not everything I'd like to help with this swap if I do it. Just would like a lot of input, advice & any helpful links. Thanks!!
