Default WMI or PW TMIC?

So I'm on a budget for one of the two (for now) and i need your input on this.

Here goes: 08 WRX stock. I already got a Catless downpipe and a invidia N1 resonated CBE. should i get the Process West TMIC or Aquamist HFS-3/4 kit?

The reason I'm torn is that WMI seems to be a freaking good mod that will reduce my temps significantly (since i'm in Kuwait and temps here are oven-like) and reduce chances to knock. however i'm afraid the increased boost the WMI would allow might be over the stock intercooler capacity. If i get the PW TMIC that would be great but i'm sure it would be less effective than the WMI.

what mod do you think should come first? car will be protuned.

get the intercooler, the plastic ends of the stock tmic stuck and have been known to leak past 18~19psi. The Intercooler will be way more effective then Water injection at this point. Get all the supporting mods first, then look into water injection.

Also OP I hope when you say your car is stock with a catless downpipe that you're still not on your stock tune. You will grenade your engine. Don't go into boost until you get it tuned if you dont already.

Freddy, thanks for the input. the car is still stock in regards to hardware and software. the Turboback is in box still as i intend to install everything at once and get it tuned then.

+1 on the intercooler. My tuner told me he won't push me past 18.5 until I upgrade my TMIC. The end tanks will eventually start to leak or worse. Process West is a really good option. There are other cheaper options, but remember, most of the time you get what you pay for. It's a shame Subaru switched their IC design.

And for the record my car is a 2011 with intake, turboback, and EBCS.

If you are looking for cheaper intercoolers (you said you were on a budget, or did I read incorrectly), you could always look at the FMS top mount. Although there is large debate about knock off brands and all that jazz, in my experience the intercooler does a fine job of providing a adequet amount of cooling to the charged air. In the car's I've seen tuned with it the tuner has had no issues adding the expect amount of boost without experiencing any det due to too high IAT temps from the charged air.

I'm actually considering buying one, welding a spot for an IAT sensor post intercooler, and conducting some tests myself just for the sake of having more reliable intercooler data. If you haven't seen already the data on how effective different intercoolers are (not just how much they flow, but how well they actually cool the charged air) is very slim here. You sure will find a lot of people making all sorts of claims though without anything to back them up. Even in this post I have no hard data, but I do have experience with 5 different cars using the FMS intercooler all with good results.

I'd love you long time if you did this as there has been near ZERO data about any bigger TMIC. BE SURE to use two temperature probes though....one pre intercooler (intercooler hose) and one post intercooler (throttle body) as this is how you determine intercooler effeciency. Using only one leaves room for naysayers. You could also do this in conjunction with/without waterspry and with/without turbo wrap. Hell, if you get the time/money/balls to do this, I'll buy you a turbo wrap kit to use/test.

I'd leave the MAF sensor alone and use the IAT from there to compare to the ones post intercooler. Where would you suggest welding the second sensor, I was thinking welding it at the end of the intercooler right before the throttle body.

I second the FMS tmic suggestion if you're on a budget, I love mine. $420 shipped from IIR. You just have to be willing to fuss with the bpv screws a bit as the bolt holes are quite small.

My tuner recommended it, otherwise I wouldn't have considered purchasing a "budget" part.

Don't forget about a fuel pump either. If your turnin up boost you'll max the pump.

If you are a weldy guy, that would be the right spot. Or if you are a gluey guy, you could put it into the throttle body hose like the water spray dorks do. As long as its post intercooler that's all that counts though it would probably be 8.5% better if done in the hose as you can test 19 different intercoolers this way if you want.....in a perfect world, you'd do stock pulls, then aftermarket pulls so ruining a $9 hose is better than a $XXX intercooler if you follow me.

PM me when you are ready to roll on this. I will paypal or straight up send you a turbo wrap kit to use. Not sure if it will make a difference at speed or not, but at least you could prove/disprove it if you have the time and desire to test it out as well.

I'm going to get in contact with AEM and buy one of their IAT sensors (unless you have a better [cheaper] option. I don't have the financial luxary of testing a variety of different intercoolers at the moment, but maybe if I get the ball rolling on this some of these other companies that produce intercoolers might want to contribute to the testing . I can get my hands on one of the FMS intercoolers easily, and I know there is alot of debate about the "knock off" or "replica" brands basically being ineffective, so that's where I'm going to start.

I'm a weldy guy , as a simply glue job just doesn't seem to be a smart thing in a place where 20+ psi will be seen, maybe that's just me though. If I do this testing I'll have to hold off my temptation to get a SD tune on the car as soon as the sensor is installed, hah.

I am extremely curious about finding out the results of these tests though
