Yo yo. I got a built engine from MonkeyWrenchRacing.com in December and I'd do it all over again if I had to. You'll get some things overpriced from them, but they do excellent work. Look around on the CelicaHobby store and CarID.com for stuff you think might be overpriced. I went from a 1zz that was burning oil by the gallon to a 2zz with forged internals and some other sweet bits (Exhaust, Short Ram, Short Shifter, etc.) and it's like a whole new car ($5000 later).
The install wasn't too different from most other engine swaps. A few things you might wanna keep in mind are whether or not you want to keep your 5-spd or swap it for a 6-spd, what stuff you'll want replaced while you're in there (radiator, hoses, axles, etc.), and the things that will NEED to be replaced (Exhaust needs to be wider, burn up all that regular gas and fill it with 93 Premium, you'll need a new ECU and you'll want a rebuilt motor, not a used one). Just be prepared to hunt gremlins for the first few months. I had to prime the cooling system at least 15 times to get it working. It took weeks and I still find a wire or sensor here and there that needs replacing.
Do plenty of research and create plenty of shopping carts. Good luck!
