Engines, Purchasing Options

[mr_dude]

So I'm soon to pass the 200,000 mile mark. I have to think about the future.
Everyone talks about a 3SGTE swap and it sounds good, but the details elude me. I'm a few months from gradicating as an electrical engineer, so I can pick up car mechanics easy, but I don't have any background in it. (Just did the suspension with a friend's guidance and it was fun).
I'm sure there are some extensive how-to's, and those will be useful.
Question is, what are the options for getting a 3SGTE? Would I have to find one in some junkyard and have it cleaned up? Do companies still build them (as I've heard BMW does with their cars). Are there any alternatives even if I, say, wanted to throw more money at the project than the car is worth (which I do)?
If I do get one, what kind of experience should I be looking for for doing a good swap? Can I take auto mechanics at some community college (they don't have it at UCSD) and be proficient? Do I need to find a friend who works in an auto shop? Will somebody out there do it for a sixer of Newcastle?

People who answer questions rule.

yeah its ****in more expensive than I thought it would be but hell its all gonna be worth it

Lets see.....
Engine $1750
Tranny $300
Clutch/Pressure Plate $400
Hoses $50
Wiring $150-$400 Depending if you purchase qatar's services or not (Do purchase it, he rules)
Spark Plug Wires $160
Spark Plugs $40
Supra Fuel Pump $100
FMIC $300 (you can use top if you want)
Gauges $200-$400 (depends what you get)
Flywheel resurface $40 or Lightened Flywheel $300
That sounds about right to me, and some extra cash for flukes, never know whats gonna go wrong Expensive, but kick ass hehehe.

Hope that helps you a little bit and give you an idea whatcha gonna get into for a 3sgte swap, I think its worth it for the power and potential of the engine, if not, swap in another stock engine then for a couple hundred bucks.
