I'd talk about how I'm a noob but this thread isn't about that, so I'll just get down to it.
I have: Stock '90 NA6
I want: 1.8 swap, built, bored, boosted. Hp goal: ~350 with room to grow
I found a '97 NA8 in a junkyard that some d00d apparently used for dorifto (worldwide/supreme/gimcrack stickers) and it ended up stacked on an Odyssey in south Philly. When I got the car for $700, it started immediately in my garage, found idle, happily revved. It had no doors, top, front fenders, bumper, steering wheel, or radiator. Immediately viewable were Racingbeat shocks and sway bars. The engine looked really clean, too. I got to work taking everything I could from the car in the 4 days that I had the garage available (borrowed). Out came: engine, transmission, Flyin' Miata Happy Meal (!), PPF, driveshaft, diff, rear axles, shocks, sway bars, ECU, fuel pump, some electric doodads, clutch cylinders, headlights, and a few other parts. Found a garage for rent up the block, score! Removed as much as I could from the block while it was on the dolly, then it was up onto the stand.
Since I'm learning this as I go along, I figured it'd be better to post this thread sooner than later so I don't go too far off course. The build diaries and other threads on this site have been instrumental in learnin' me some cars, so while I search and research for solutions, I'll defer to this thread instead of making more, unless I have to.
Currently, I have the block stripped as much as I can get it (need to figure out how to remove oil cooler threaded pipe without ruining the threads). I took out the cams and lifters yesterday, need to find something to help get the springs and valves out. Tomorrow, I'll find a machine shop for the first phase of the build: boring the block for the new pistons, maybe porting the head - what I've taken away is that more breathing room is good for turbos, but not too much or else you lose the "push back" that creates pressure for b00st. This takes me to the next part...parts.
Here's my parts wishlist so far. Excuse the links, they're there to help me stay somewhat organized. This is pretty much me just going through lists and build threads and copying what I'm seeing, learning what stuff does, and applying it (hopefully). The first numbers are what I'm ordering them in by priority and timeline of when I'd get them. Any critiques and input are welcome.

Get an MS3 variant.
You are going to want more than a DW200 to for a 6758 or 7163
Skip the blanket
Spend more than $200 on a quality intercooler+piping.
Don't build an NA8 head. Spend a bit more to get a 99-05 head
Don't see a manifold listed there. Get a TSE manifold+downpipe, and then their intercooler setup whenever it comes out.
Both those turbo's will blow a 6 speed. Either plan $3-$5K to pay someone for a transmission solution, or build one yourself.

MS3 as said. Also I would not spend a penny in the head. You can make 400+whp on a stock 99+ head. I would get a VVT head, leave it stock. Get a flat top intake manifold. EFR 6758 as the turbo mated to a TSE manifold and down pipe.

TSI's are sold because people think they are cool looking and race inspired.

TSI let air in to the engine compartment that doesn't have to go through the radiator. Because it slightly pressurizes the engine bay (relative to no TSI), there's less air flowing through the radiator. Radiators are what cools an engine, not air flowing past the block.

Short of you building your own manifold and exhaust. Nothing on the market will be cheaper or better then the TSE setup.
VVT is not needed, but is a very nice thing to have. Helps out mid range a ton. I would take a stock VVT head over a 94-97 head with all the head parts you want to spend money on.
6 speed will probably handle 350whp on the street, but I would plan on having a spare one laying around. It should be considered a consumable item at those power levels. Its not worth the cost going inside a 6 speed and no one makes stronger gears or anything for it.

I guess I don't have to quote everyone in my replies. I feel from the explanation about the TSIs, it does make sense. What solution does one have for IC in front of the radiator if the intercoolers I'm seeing rated to this HP are covering up a large part of the radiator? Or does enough air get around?
TSE's kit seems to be universally shown as the best on here, in other threads I've seen people talking about a wait for them? I have plenty of time, but how long is the line to get one of these kits? Thanks guys

Don't open the motor right now, just put it in stock. Doing everything at once is a big undertaking. People bite off more than they can chew all the time, the build loses momentum, never gets running, and eventually gets parted out. Break it down into steps, you'll be much happier and more likely to actually finish the car if downtime is kept to a minimum.
Install the stock motor and get it running. Get the megasquirt and get the car running. Install injectors and retune the car. Get a turbo kit and run the car at low boost for a while. Source another motor and build it, then when it's ready swap motors and sell your old one. If you manage it right you'll never be off the road for more than a weekend.

I'm seeing '99 heads on ebay for about $400. That doesn't seem too bad. Is it wise to change out sprints and valves when buying a used head, or wait to see how the car runs after dropping it in?

I can identity with that ^^^^ statement 100% I have the ability to fab a lot of parts, and this was a 17 month project for me. Because full time job. I highly recommend not doing it all at once. Maybe build the motor and install it for now. That will give you a good head start, and insight to the entire project. Also minimum investment if life happens and you can't finish it.
