ST185 RC Intercooler into ST162- Help needed

[Aerrow]

Hello everyone,

I am doing a 3SGTE into ST162 swap using an ST185 RC. So far the swap is going well but I have run into some trouble. I'm going with the water to air intercooler that came with my front cut and I need help working out the wiring of the pump and sensors from the intercooler. From what I know the stock pump is set up to shut off when the turbo isn't boosting. What do I need to do to get the stock set-up running in m ST162? I have everything from the ST185 so getting parts isn't an issue. I have heard that some people have rigged the pump to run constantly, this sounds as if it might be a plausible option for me, anyone have some info on this mod?

Cheers!

I would hard wire it in so that it is on constantly when the ignition is on.

How you do it with the stock pump i have no idea however.

check out www.gtfours.co.uk/ it could be similar to the st205 pump.
im pretty sure the 185 level sensor is same as the 205 and you just ground it, but this means u could run low of coolant and not know so be proactive and check it regularly. as for the pump pick the wires that are thick they will be your power and run these to a fused, switched relay. as for tricking the ecu. you will have to google this, it can be done with resistors, i did it to my 205 ecu, alltrac.net has some good 185 info.
hope this helps

I'm running a Liberty water-air intercooler on my older Leone turbo RX (which don't come with an intercooler at all).
I got it out of a donor car & they'd wired up a system where a switch was installed on the throttle body to activate the pump at full throttle.

Therefore, the wiring is completely separate from the ECU wiring.
Personally, I reckon the most heak soak occurs when the car's idling because there's no air flow.

So I'd be running a pair of switches in parallel for full throttle & idle, and then have that in series with a float sensor. This would then be on the trigger wire for a relay which operates the pump.

have you meshed the st162/185 loom together and got engine running yet?

if you want to run the IC pump constantly/bypass the ecu control you'll need to implement this


i just did this today, my setup is a little different. i have an st185 running st205 ecu and engine, but i used an adapter loom and then wired this in as i don't have the STD pump (bosch "cobra" pump) nor wiring going to the IC water level sensor or assoc relays.
