STi air-water intercooler??

kotaro · 12-13-2002, 05:35 PM

Is this really an sti part or is it just a standard one painted in silver and with some different stickers?

A standard air-water IC:

An STi one?:

(all the pics are here )

Besides the different color, and the different stickers, the silver one has 2 caps or two openings in the top, while the black one has only one...so maybe it is an STi part?

Anyone knows anything about this?

I think its only a standard subaru air-water. knowing that its a legacy chassis with the EJ20T engine. Sti made only a handful of the ultra rare legacy turbo STi RA, and I think they still used the stock air-water IC. But yes, to me it looks like a standard legacy turbo with the stock air-water

Mark,

Those are right hand drive right? The location of the brake fluid resovoir and wind sheild wiper motor is freaking me out.

On the right side of the picture on the rear most intake runner is a tan colored item, is that the Idle controller? Where would the ABS controller go on these cars?

kotaro · 12-13-2002, 07:50 PM

Yes they are right hand drive cars, and if I recall correctly, ABS was optional not standard on RS turbos.

And I still think this MIGHT be something different from the standard IC...I mean I see 2 caps in the top of the silver one v/s 1 cap in the top of the black one...

biggreen96 · 12-13-2002, 07:54 PM

If you look real close you can see a hole where the cap should be on the black one.

kotaro · 12-13-2002, 08:00 PM

I can't see anything...so I went to fullboost to search for another pic and found this one

and I can't see anything either

kelley · 12-13-2002, 08:05 PM

what about the airbox in that first pic. does any body know anything about it. that is exactally what I've been looking for.

ciper · 12-13-2002, 08:20 PM

Looks like it was home made to me. I did something similar on my supra.

The easiest way is to make the box the way you want from cardboard. Get it exactly the right size then use the cardboard as stencils to cut the material. I bought a big peice of broken plexiglass for cheap and made a decent looking air box.

biggreen96: I think the silver one is different, I used photoshop to brighten up the areas of the two other pics and no hole exists on the passenger side of the intercooler for the black ones.

biggreen96 · 12-13-2002, 08:40 PM

maybe I just saw a smudge of dirt...

kelley · 12-13-2002, 08:54 PM

hey ciper, I get some low quality primered pics of the aerotech body kit could use photoshop to make it body color and freshen it up. thanks, kelley.

ciper · 12-13-2002, 10:04 PM

kelley: I could try, Im not a graphics artist or anything show results may not be so good.

SubbyRS · 12-17-2002, 07:38 PM

I have a '91 Legacy RS with the black water/air intercooler....AFAIK the only difference between the black & silver units is the silver one has a water level indicator/sensor which is the connector on the RH side of the intercooler...my black one doesn't....in terms of capacity etc, they're the same.

Legacy777 · 12-18-2002, 09:16 AM

ciper.......that tan cap thing.....is the IAC valve....if you were still wondering....

Jaxx · 12-18-2002, 02:16 PM

i have a black on in my garage ..i can take a bunch o picts if people would like .. it will probblay go up for sale soon

in background .. bad pict

ciper · 12-18-2002, 04:07 PM

Jaxx: ej22? From a RHD?

HomeSlice · 12-18-2002, 04:45 PM

those pics made me mess up my pants-----"Thats not chowder!"

Jaxx · 12-18-2002, 10:00 PM

EJ20G from a 89-93 RHD Legacy RS
exactly what is pictured above

220 PS
closed deck
tdo4
425cc injectors
coil on plug
relitivily cheep $650 no harnees no ecu

i have a tec 2 that i am going to use ..

current prob is making it idle
it has a 3 wire stepper motor .. ?

ciper · 12-18-2002, 10:05 PM

Yeah, combo stepper and metal "heat" spring. What about just setting it at a decent point, and let the metal spring take care of cold to warm transition? Your idle would be different based on the weather but still in a good range. I was playing with mine once, turning the valve by hand.

Jaxx · 12-18-2002, 10:40 PM

Jaxx · 12-18-2002, 10:42 PM

intersting idea....
i havn't taken it apart yet
not sure if that will be goo enough
might have to find a GM stepper motor to fit

ciper · 12-18-2002, 11:19 PM

Man, the inlet on that looks very small and some weird bends. Forced induction may overcome this but still!

Here, old but might give you an idea.

warlord225 · 12-19-2002, 12:51 AM

yes, that tan coloured thing is the idle controll unit (the one with the 3 wires).
i see alot of these motors.
also the cars are suprisingly fast, but not as fast as our gtb

kotaro · 12-19-2002, 01:51 PM

thanks a lot for all the answers and info
