[mycelicagt]

i just ordered a st205 motor and i was wondering all the small parts that i would need to find for it, i do not have the front clip, but i do have the GT

Hopefully your engine set is very complete and you have things like:

1.) Uncut harness.

2.) MAP sensor (BPS)

3.) Intercooler pump, wiring.

4.) ECU

5.) Fuel pump resistor

6.) Heat exchanger for IC

....and so on.


If you are missing any of those parts, you can sometimes find them floating around on AllTrac.net, MR2OC (MR2 3rd gen uses similar components, but not all the same) or EBay.

The ST205 swap is very straightfoward on a 6th gen US model, the main plug EA1 in the junction box is directly interchangable with the ST204 platforms, as are the interior plugs, making things much easier.
If you don't have the rest of the engine room harness after the junction box that would be found on the clip, you will have to bust out the BGB wiring diagrams for the ST205 and wire up a fuel pump relay, as well as a relay setup for the intercooler water pump.


Good luck with everything, and enjoy the swap.
