Default air/water intercooler

does anyone think it would be a good idea (and possible) to fit a RS legacy air/water chargecooler to a wrx?

does anyone also know possible performance gains compared to stock ic, other tmic or a fmic?

thanks.

Should give a much cooler charge, very good for 1/4 type stuff.
i've seen this done, although it was a very long time ago. anything is doable Someone in our ranks is putting a wrx motor into a 67 vw bug, that's a much larger project then air/water ic

I'd look into a more professional setup first. The legacy one is frankly quite small, and not really sized right for best performance.

Definitely good performance. You may not think it is worth it if you hire someone to do it. Now if you could engineer one and let the rest of us in on it.

Regarding kewl Subaru boxer uses - I happened across a site the other day discussing using a 2.2L closed deck in an airplane.

When I get home from work I'll post a link to a site with a nice A/L intercooler setup. It uses three Laminova cores if memory serves which, if you're unfamiliar are one of the most efficient designs. I've been seriously considering one of these. Here's a link to Laminova's site

There is a company that builds intercoolers for RX-7s and Typhoons/Cyclones in Texas... When I get home I will post a link.... but what they do is instead of using water to cooler they actually plumb into your A/C system and use a condensor to cool the intake charge.... pretty slick setup... and if memory serves me (the link is at home and im at work) the parasitic drawbacks of runing the AC system are actually negates by dropping intake temps by 30-40degrees in the Texas Desert


Will post the link asap

being small is the whole point...water is 4 times more efficient than air as an intercooling agent....trust me, there's only 2 disadvantages to using water/air intercooling over air/air intercooling: added weight & added complexity. My Legacy RS comes standard with the water/air cooler & never suffers from heat soak....FWIW the standard Legacy water/air cooler is good for around 290HP (crank) before the radiator and/or water pump need upgrading...

I don't mind small, but looking at the Legacy one, it just looks to be of poor design. If it was 1-2" thicker it would be ALOT better as then the core would be roughly the same thickness or greater than the TB opening, and thus reduce the restriction at the TB side of the Intercooler.

I will be doing this Mod whenever I receive the Legacy Turbo to Intercooler Induction pipe w/ BOV flange from NZ. It doesn't really matter that the core is small, as I am going to use as big a reservoir as possible and hopefully an old VW Sciricco Radiator to cool the charge even further.

I still have yet to get confirmation on whether I will be getting the Pipe w/ BOV...... though, once I do, I'll do a nice little write up.

Yeah, I was in contact with some of the people who run Laminova, and was VERY interested in their set up. The only drawback is that you pretty much have to use their entire set up. That is, you can't just use their Cooling core with the Legacy Topcore, or vice versa. So their total price is about $1,200. Where as if you can do it right, the total price for a Custom job w/ Legacy core will cost approx $500-600.

Hey XT6Wagon, where are you looking? are you looking at an actual Legacy intercooler? or the water/air intercooler at the PDM link? just curious 'cause the Legacy item is WAY bigger than the PDM one....I've got some workshop manual diagrams if you're interested??
