My take is w2a is good for an every now and then driven car or drag car.
A2A for street cars.

All for the same reasons Ben mentioned.

With an w2a you have more weight, plumbing, lines, parts, added electrical load from the pump and heat exchanger fan if you decide to run one and the sheer cost is significantly more.


My IC piping is 10" long total on my NX. Cody (lovefab) and I messed around for about 2 hours just to fit my IC. I run 1/2" rubber hose to an IC with a small heat exchanger. The weight of my W2A IC and heat exchanger combined is the same as my A2A IC unit I was running. The added weight comes from a plastic tank, a pump, the hose and the water itself. I put my tank in the trunk for weight distribution and increased capacity of the lines. I have never had a pump fail, water leak or line freeze in all the setups I have done. 6 ft. of IC piping is just not something I want to deal with, as well as blown couplers/busted clamps and so on. Those are just my thoughts on it.

We can go around and around on pros and cons. It ultimately just comes down to preference and what you have success in using.

People talk about heat soak as the major issue with W2A, but honestly, it just isn't something I have had an issue with. If I go to a HPDE road course event, I might drop half a bag of ice in between long sessions. Most of the time, the ice is still in the tank and I don't have to add any at all.

What I was looking for haha Thanks Coach. Did you happen to get a look at the parts list?

LOL I work at a shop, free washer fluid! Checked the container and it is indeed Meth/Water/Colored Meth mixture. Awesome haha. Looking at the AEM units.

The kit you posted is nice. You might be able to do it cheaper buying piece by piece, but I doubt it. The BOSCH Cobra pump is actually pretty nice, though they aren't rebuildable. That being said, I have never had to rebuild a jabsco pump in all the years I have run them so I wouldn't worry about that.

On to endurance and long term use, I don't see an issue running even endurance racing as Toyota did it with the Celica GTS All-Trac rally car which was W2A. It all depends on power levels and what you are doing. If anyone actually hooked up an IAT sensor and logged intake air temps after hours of use, you would be surprised how well the W2A keeps up.

I might look into logging some Intake air temps next year when the car is finished. Slowly acquiring parts like everyone else =p. The range of gauges for this is slim though.


Here's the pieced together kit. About 600 +- 75 bux probably. Not including fittings and hose. Compared to the 512 or so for the other kit with the Bosch pump (the votion speed kit has a 2.6 gallon tank).


Seems the Jabco pump is a bit better but not enough to fret about. If the bosch were to ever fail I could just upgrade. All around, both seem like viable options.

I bought this kit (basically exact same) and ran 24psi through it with a 60-1 and no issues.

I just don't like the two ports on the same side, there'd be some serious 90* bends to get from the turbo to there. That is a cheap kit. You're basically saying that the ebay intercooler held pressure fine with no drops?

With ebay parts and a jabco pump, could definitely pull this off for under $500, with a Jabco pump and jazz cell.

Note* main reason for posting a bunch of links is so I can come back to this when I'm ready to purchase everything haha. Easier than updating my thread in the "members rides" section.

That works to, I was just saying, lost of options. The Ebay units worked fine, and they are the same as the Votion kits you posted at the beginning.

I also managed to find someone that could put together trunk mounted tanks with built in pumps. Make the setup a little bit more...manageable

THere you go, that rocks. Post up if you do it so we can check it out.
