Air/water, supposedly good up to 300hp. The only way I could see it fitting is to change the throttle body position so that it is closer to the firewall. The you could try to fit it in the little valley between the head & the intake (after re-routing some wiring/etc.). Thoughts?

It's almost too cheap to pass up ( < $100 for the whole system). I'm having a tough time deciding...

PS- ignore the insignia on it!

Well, it looks like the one I have from a Toyota Celica All-Track. I plan on playing around with it this winter. I think it will fit over the head, in the 924 GT intercooler position, with a little modification. Let's keep each other (and the board) posted on progress.

Sorry I can't play with it now, I have too many other projects underway.

BHO who sometimes comes on the board has one from a jdm Subaru.The inlet and outlet are right on toop of each other and are located more in the middle of the unit,easier to plumb in the necessary lines.He has it fitted in the battery compartment and it looks awsome,perfect fit.They come up on ebay about once a month and are the same in price,about $75-$100.

i have mine mounted in the batt. tray area its from an 90 eagle talon eclipse or laser there all the same. just had to change the outlet to the side. its pretty good sized and works real well the plumbig looks awesome. i mached the pipes out of 1.5 pvc, took it to a shop i know and the welded it all. the only prob. was the t/b intake with its oval they had to cad it which cost a little more. the i/c was free and shop work was 250.00 it was worth it though. i'm gonna have to get an air/air or an air/water now though.

I also have landed a Toyota air/water intercooler like mick's, and looked at all the options of combining intake, cooler and throttle body.

Vince made the point recently that one of the factory racing intakes had the air flowing through (a) turbo (b) throttle body (c) intercooler (d) intake manifold.

Using the same intercooler that mick has shown, it is (should be?) relatively simple to insert the intercooler between the throttle body and the manifold, by moving the throttle body towards the rocker cover.

A question I need answering is about the intercooler having enough time to cooler the air charge. At WOT, I think the time the air is in the intercooler would be the same, when comparing the option above and a traditional layout. At idle the intercooler is not working (much). The difficulty comes when the throttle opens during acceleration. In the traditional configuration the air would have been "resting" in the intercooler, but in this layout, the air does not see the intercooler until 'it is needed in a hurry".

Does any one have experience with or an opinion with this alternative?
