BigNate i personally avoided APR during my search since i did find a few negative comments about the way they conduct business,i was able to locate a couple of good engine builders with a good background and did not find any negative comments about their company.I have purchased my engine from Raptor Engines out of Oregon the price was right and came with 7 years 70k mile warranty as long you stick to their requirements,i also found Yota shop from Washington state who builds only Toyota engines only and also have a good warranty. check them out and see if you like what you see.here is some link.
YotaShop offers Quality Toyota Engines and Parts
Raptor Engines, 7 Year 70000 Mile Warranty
The only reason i went with Raptor is the warranty and a few hundred bucks cheaper,my engine is currently running and fired right up after install.no problem so far and the guy in charge answered all my questions prior to buying the engine.
