The 3SGTE Swap, How-to Options

[brianforster]

oh really, do you think it woudl be cheaper to run a water to air tmic than a fully custom fmic? on an engine with currently no intercooler..

[Defgeph]

I'm not sure if it will be cheaper, but its definatley something to look into.
You might find some nice water setups on ebay.

If I did it all over, I would still run water.
Turbo Lag = 0 for me

[brianforster]

thats interesting.. so i dont have to keep picking your brain, do you know of any in depth guides to water cooling?

i doubt i could find a full setup for sale that will bolt right on, im sure that would be too easy

[Defgeph]

Dont worry about the questions, I'm here to help.
Not sure of any write ups, somebody might chime in with one.

I can list parts
1. intercooler
2. water pump
3. Heat exchanger (like a small radiator for the from of the car)
4. hoses to connect everything

And that about covers it.

[brianforster]

cool, perhaps ill have to look into that, except it seems like the parts would be really hard to find

[Defgeph]

ST185RC IC setup



ST205 IC setup


This should help you

[brianforster]

thanks man you are awesome! now i just gotta learn how to read diagrams like this hehe

[Defgeph]

The 205 picture is easier to understand

to the left is the heat exchanger (looks like a radiator)

Bottom right is the water pump

Top middle is the intercooler

some hoses that connect everything.


and other parts that you dont need to worry about.

Since this thread is active again I've got a couple questions...

1. Which fuel lines can be used to connect the 3SGTE fuel rail to the filter? 3SGTE or 5SFE?

2. Which heater hoses will I need to use? 5SFE, 3SGTE, or custom?

3. Which radiator hoses should be used? 5SFE, 3SGTE, or custom?

Also, you might include in this How-to what you did to fix your error codes that were caused by the W/A intercooler ECU or lack there of.

[Defgeph]

1. 3s fuel line to the GT filter
2. I used the 3sgte heater hoses
3. I have an ST radiator. I used 3sgte for the top. And I made my own hybrid lower hose. using a GT lower and some other hose that fit.
If you have a GT just use the GT lower


Thats a good idea about the ECU, maybe I'll do that.

Thanks, but let me make sure I'm getting this right since you were swapping into an ST...
5SFE fuel line from rail to filter will not work?
5SFE heater hoses will not work?
5SFE upper radiator hose will not work?
I realise that you may not know since you had a 7AFE but maybe someone else could answer for sure.

Also did you retain the EVAP system?

[Defgeph]

The 5sfe stuff will probably work. I like to use the 3sgte hoses, less things to remember.

By EVAP do you mean the charcoal canister ? or the a/c evaporater ?

Yeah I know what you mean by less things to remember but it'd be nice to know what is compatible... Hopefully someone that has swapped into a GT will chime in.

Evaporative Emissions... just curious if you kept it, not that it matters.

[playr158]

i'm just wondering do we have the
96+ ST wiring harness diagrams and the
st185 wiringing diagrams?

[Defgeph]

I have the hose from the engine to the canister connected, I beleive the purge is just left open.

I haven't found the OBDII diagrams for either the AT200 or the ST204. Some one will either have to scan them or pay for a subscription to TIS... http://techinfo.toyota.com/

The ST185 diagrams can be found here:
90/91 - http://www.celicatech.com/imagearchive/bgb...0celica_ewd.php
92/93 - http://www.celicatech.com/imagearchive/bgbonline/93tech/

The 93 BGB is almost complete but the menu for volume two is apparently MIA so I just use the directory listing to navigate both volumes.

This scan will tell you exactly what each folder in the directory listing contains:

A few new things going on with my engine. I ordered an ATS fuel rail which should be here by the end of this week.

I also had my injectors tested and cleaned.


Now I can say I have no worries at all.

[playr158]

very nice jeff!

[presure2]

good stuff jeff.
good to see that the injectors wernt in bad condition, but always better to KNOW theyre clean!

[x_itchy_b_x]

always nice to know.
