JDMs are just a bit of a crap shoot IMHO. I prefer to know what is actually going on in there and what parts were used, etc.

So as an estimate (These are close to the prices I actually paid, obviously not to the penny, but close);
- $800-ish in machine work. Which includes, fitting new pistons, decked block, all head work, cleaning, etc.
- $180 for Nippon ( OE supplier ) pistons and rings
- $150 for Main, Rod and Thrust Bearings ( Taiho OE supplier)
- $150 for OE Toyota head gasket kit.
- $180 Gates timing kit (included Aisin water pump).
- $65 Aisin oil pump.
- $35 OE knock sensor harness.
- $15 Toyota FIPGK
- $50 new OE shims (as needed, each engine will vary)
- add another $150 for incidentals and things that didnt come in various kits

$1775 grand ball-park total. That is of course with me doing all fitting and assembly, installing, etc. (except pistons, which must be fit at time of machining)

As you can see, I did a fair amount of work to find OE supplier replacement, and Toyota parts. This did probably cost a little more up front, but a whole lot less than doing it over again in a few miles.
