Water to Air Intercooler Install *Pics*

Well after about a year of having a w2a intercooler on my workbench, I decided to install it.

I had to remove and relocate the condenser behind the radiator in order for the heat exchanger to fit, and I need to finish the pipe for the sc14 to the w2a intercooler, but other than that it's pretty much done.

Heat exchanger install - The hoses are 1in OD and 3/4in ID the cooler is about 24X10X3

Black grill didn't fit completely flush, but it fits well enough with only a slight bend in the middle.

Ignore the dirty motor, I haven't cleaned it in a little while, and it's on my to do list :thumbup

For the intercooler, I wanted to retain the stock location. I made mounts for each side to use the stock intercooler mounting points.

I made the pipe to the intake manifold, and routed up the coolant lines. The pump is from a lightning and it's located down by the charcoal canister.

wow, they both look really great.

Is there a lot of added weight with that setup?
and how much water does it take to fill it?
Yes there is added weight, I bet the system will take just over 1 gallon of water and with the intercooler and heat exchanger, add about 35lbs over the stock intercooler. That's just a guess, so don't quote me on that. haha

Well I learn a valuable lesson today. When I hooked up the lines to the heat exchanger I guessed on which one was which, and turns out I had the return running to the lower entry to the Heat exchanger, and not the upper, so it heat soaked bady and didn't work. I removed the bumper again, and turned this around, and wham, cools like a charm!!

One thing I did notice though is with the sc12 and the 2.5 in intercooler piping the car got slower, or feels slower. I think it's because of the 2in out let to 2.5 in to 3 in then back down to 2 in. I think this will be fixed with the sc14 goes back in because it's all 2.5 in piping.

Front mount and intercooler looks FANTASTIC! A2W intercooling is really coming down in price as it appears you can get a complete setup for around 500 bucks, while utilizing quality parts. I mentioned it before, but the Bigger Twinscrew kit looks as if it matches up perfectly with that intercooler in its current location.
Great work

Looks very similar to my set-up which was good for 177 rwhp with the SC12. Nice going! Have you bored out your TB yet?
I haven't bored out the throttle body yet, but I"m looking into a camry V6 one which I believe is 65mm. BTW what size piping did you use? I'll be at 2.5in on the sc14, but right now I'm at 2in from the sc12 to the intercooler, and then 2.5 from the intercooler to the intake manifold.

Also did you feel like you lost low end torque when you added it?

Finally, that stupid 90degree silicone bend actually caves in under vacuum, anybody know if that's normal? It pops back out whenever you rev it, but under vacuum it just caves in and very little air passes through it. I'm wondering if I should change that thing.

curious..which heat exchanger is that, like the 05 cobra?

Just curious, because at wok we sell upgraded heat exchangers for the Cobra, I think its fluidyne? or granatelli but either way.. it looks about the right length for the MKI up front.

But nice looking setup.

I am still using quite a bit of stock piping (2" diam.?) but the IC I am using has 2.25" inlets so there is a small section of 2.25" piping. Not as much of a change as you have but I really don't remember losing a lot of torque. My IC is smaller that yours though ( part 2-252 here http://www.racetep.com/tneticatolic.html)
Here is the original post when I did my setup in '04. FWIW here is the link to the post on my setup http://www.mr2oc.com/showthread.php?t=46211

Couplers MUST be spaced no more then 1-1.5 inches away from your tubing. Your entire system is under vacuum with the s/c. This also goes for bypass valve. That was lesson 10 or 11 learned the hardway with the Twinscrew. I think you also might have a boost leak, hence the loss of power.

It's the same exchanger that USPSPro had on his mk1. It's a custom dual pass from ebay. It's a 24X8X3 and fits pretty well up front, and uses 1/2in npt inlet/outlets.

I almost bought one of those fluidyne cobra exchangers, and I bet those would work well.

Thanks for the help, I'll keep working on mine. I would have prefered to use an intercooler like yours, but I couldn't turn down the $140 price tag for the xspower crap.

Help me out here, you mean the gap between pipes in the coupler can't be more than 1-1.5in right? If that's the case then thats where my problem is with the 90degree reducer, and that's the piece that's caving in under vacuum. I'll put a pic up of it in a bit. Other than that, I can't imagine any boost leaks, as I only added 1 pipe, and didn't make any welds for it, and used the tbolt clamps and they are clamped down tight.
