ST205 service parts interchangeability

Tue Nov 05, 2019 7:24 am

Hello everyone, so I received my ST205 swap last Friday.

The engine is from a WRC model with the anti-lag. I plan to do the typical maintenance: t-belt components, oil and water pumps, clutch, etc.

My question is, what parts interchange with the ST185? I know the timing belt is a tooth off, but how about the rest, where do you guys buy the service parts for these engines. Thanks in advance for any input.

I'm a bit surprised you haven't received a lot of input on your question from this forum yet. I can't really help you as I don't have any ST205 engine experience (just ST185). There is a fantastic parts source tool I use often - "www.toyodiy.com". If you register for it, you get the exploded views with all the part numbers showing for most any Toyota, and you can select the regions across the globe where you want to do your search. You might want to register on that site and take a look at it - it will provide answers to all your questions.

I think the question is too general. With more specific questions, you might get an answer, I guess.

Anyway, in my 185 are living 205 pistons and an 205 gearbox. Probably more parts, but I forgot. :shrug:

*edit* and injectors...

Before I mount the motor and trans, I want to service the timing belt area and clutch. I already found what I was looking for in another forum. Once I replace the parts, I'll update the fitment here.

If i were you id buy a complete OEM engine gasket kit and change all the gaskets and seals you can while the motor is out. Seals dry up and so do gaskets. I myself on my 205 transplant also took the head in to get refreshed as i knew id be using the motor to its limits and wanted no issues.

R-town, could you please post what you learned in your research? It could be helpful if other people have similar questions in the future.

I forgot to mention that i bought a full shim kit to adjust the valves. If anyone needs some let me know. These are odd size shims not readily available in North America
