The engine and trans are Japanese Domestic Market from
https://tennesseejdmmotors.com/ They are supposed to have less than 50k on them. This one looks like it came out of some kind of RH drive car. Celica maybe?
The only differences I've seen so far:
The shifter select lever shaft is different and will swap from my old 6 speed.
The knock sensor is different and must be swapped along with the mounting stud.
The rh engine mount bracket has a different part number. Even though it looks like it will work, I swapped it over. I'm also using all of my old mount brackets because it's easier to do it now.
I'm swapping the throttle body because the the one I received looked slightly damaged at the cable quadrant.
A couple of small brackets, etc., due to rh to lh drive differences.
The rest of my old harness hooked right up. FWIW, I disconnect the harness from the ECU and feed it through the firewall and pull it out with the engine. It's much easier to work with this way.
I'm waiting for a few parts before I install it. I've already installed a new clutch am about done with swap-overs. I'm about 6 hrs into this.
