ST205 Total Rebuild, Something a bit different Options

[antoine64]

bit of a note about the front flexible brake lines. there is a right and left line. I put mine on backwards then realized and had to swap them. the part connecting to the caliper bends at a different angle for each side. it's a tiny difference that's easy to miss.

The odd but of progress, I have been doing some design and preparing stuff for the engine rebuild. Getting more parts zinc plated, redoing wiring, battery relocation and basically waiting for the dashboard to get finished.

More parts in the engine bay, pretty much only missing the engine now, and a few radiators

[Tigawoods]

Is that a TRD engine mount?

[Nial]

No, it's just the standard ST205 engine mount.

[Batman722]

What's the bracket above the mount for ?

[Nial]

Its a brake stopper, helps reduce the flex on the vacuum chamber under heavy braking.

time to refurb my spare rear diff, although i have fitted one to the car already, i am not happy with the amount of effort i gave to refurbish it, basically just a coat of paint over the top. I decided i needed to completely break one down, de-rust it, ft new seals etc. get it as good as i can before fitting it to the project car.

Mid breakdown, plenty of rust to go around



the insides look pretty clean and not too worn out



Broken down ready to be either wrapped up to avoid contamination, or to sit is Deox C rust eater.



as well as some parts being sent away to the zinc platers 8)

So much rust for such a young car.

The diff came off my old faff, it is 21 years old, remember the UK isn't the sunniest of places and they salt the roads at winter time which doesn't help the longevity of any car

Yeah, salt is killer on cars. I'm glad the stuff never hits the roads around here, even when it does ice over they use sand. You'd think in this day and age they could invent some kind of coating to put on roads that'd make them hydrophobic.

Oil?!

[Box]

That's not permanent or safe. I'm sure there're people that've dedicated their life to finding something, but it's either too impractical or too expensive.

bravo for such an awesome job. how much power are you planning on making? are you upgrading injectors?

I got rid of this resistor pack and re-wired the engine harness to support high impedance top feed injectors.



I bought one of the 3rd gen rails on ebay and it worked perfectly. just an idea. engine bay will be cleaner with less clutter in there.

[Nial]

Not sure what I will do with injectors? It there for the time being so I know where it goes, if I go with high imp injectors then I will remove the resistor pack. How easy is it to rewire?

Which component is the resistor pack, and can you please explain the two different injector configurations to me. I am learning and love watching this thing go back together.

it was actually really easy. if you look at the wiring diagram, the resistor pack is a single wire in and 4 hot wires out. all you have to do is take that single wire in, and use a jumper block and split it to the 4 wires, removing the resistor pack.

[Nial]

Oh. That does sound easy...even I could manage that 😀

[Nial]

I dont like to harp on about Bilt Hambre Deox C.......but by god its good stuff.

Before



235000 miles of crud and salt etc

and after 2 or so weeks in a bath of Bilt Hambre Deox C (and some minor wire brushing to help it along.

You know what also works, vinegar. From reading the specs on the stuff it sounds like it's just super concentrated acetic acid, which is what vinegar is comprised of. Since any other acid I can think of off the top of my head is toxic and isn't bio-degradable.

[Nial]

I tried vinegar, it works on mildly rust parts but nowhere near as good as this stuff,, plus this stuff isn't acidic as you can put your hands in it and cuts don't sting. If it is acidic it's very mild.

I also tried coka cola, pickling vinegar, 5% acetic acid, all the things that people recon works "just as well" and non of them do. It's also cheap, buying 20 litres of vinegar wouldn't be that much cheaper.




Although vinegar does taste better. Sprinkling Deox C on your chips would probably taste revolting.


Hmmmmm chips.
