Upgrading A heat exchanger

Q&A regarding engines, turbos, and intercoolers and power upgrades

My RC heat condensor probably doesn't do as much as it could seeing as how the AC condensor sits right in front of it...
It's be nice to flip them and hook up my condensor sprayers.

i thought the brackets would be how they were pictured in the ad but they were not, which was no big deal to me. but you have to lose the fogs and brackets. the dim are 24x7x3 and its pretty good quality there are also pics on mr2oc b/c some of those guys are using it as well.


You wouldnt happen to have a tutorial on how to install it now would you? planning on getting the same one...


no i didnt document the install when i did it.... that was the only pic i had. i could however take pics of how it is mounted with the brackets and you can get a really good idea of how it is done.
-all i did was i had to cut off the fog light brakets :cry:
-grind down the welds
-i made the brackets out of 1/8" thick aluminum sheets i had laying around (bent them by hand to a shape similar to an S, alum is nice b/c its soft enough to work with but still plenty strong and it doesnt rust... i still want to flat black it though)
-measure and centered everything how i wanted, marked and drilled the mounting holes on the brackets
-2 bolt holes to the intercooler, 2 to bolt to the bumper support (its tricky to bolt it to the bumper support because you have to go through one of the holes which is only like 2" big and insert the bolt and hold it while you tighten the nut down)

ill try to have those pics in a few days.

I agree totally - but I would like to see how some of you folks have mounted the brackets for the 'stang Cobra HE. Pix would be mighty helpful.

FMIC FTW :D


People always talk about the weight of the Water to Air cooling system, but really if you think about it. It doesn't really matter compared to using a front mount, the associated aluminium tubing, clamps, hose couplers and brackets. The heat exchanger is the heaviest part I guess but they are usually smaller than a front mount intercooler and although it is filled with water, it's usually the only part that really has any considerable weight as the plumbing for one is neglible.

I agree. Yes, wta setup is heavier but it's not like it is 50 lbs heavier. But I think the main advantage of a/a fmic is the simplicity and fewer parts to break down.

I can see your point. I'm thinking the only thing to break down depending on the setup would be the water pump. If you find yourself using the Toyota Water to Air intercooler I guess some of the sensor's can go bad after a while and if you use a fan but not really that much more to it.

I've always looked at it like this. Considering that I'm going to find myself stuck in traffic eventually with my Alltrac, and so long as I use fans on my heat exchanger, I'd rather have the slightly more complex Water to Air intercooler and have a little bit more safety for the motor than going with an Air to Air and having my intake temperatures rise. In addition, I like keeping the tubing short from the turbo to the intake manifold.

At least the way I've weighed the pros and cons I like the water to air option better than the air to air.

I need to get mine mounted better after I am done with the car, currently its zip-tied. I am going to make a pump bracket as well.

right now i'm planning on using the metal strips with holes in them you use to strap in water heaters... whenever i get a cs bumper i'll actually get some bracket action going on...
i need to warn everyone-
