Sounds good. Understand though that the Snow kit has not favored well with Evo owners and most will tell you to spend the extra money and get an Aquamist kit.

 

For what its worth, the AEM kit does look very good for the price and would most likely be the kit that I would purchase.

 

That kit looks pretty good as well. Do you need an AEM EMS to run it though?

 

hmm, not sure. Possibly need aem ems to run this kit.

I think i've settled on the HFS-5 i'll keep you guys posted with results.

 

I might be doing this as well. Can someone PM the DIY instructions please.

 

Here's the mod I did to protect the throttle position sensor (TPS). The seal for the left side of the throttle body is achieved by a gasket that is on the TPS. The TPS innards, the potentiometer, is actually indirectly exposed to the intake air. Normally this doesn't matter much, since NA cars are pulling vacuum. If you start spraying though, you can get your TPS wet. Here's the throttle body


and what is inside the left end


and then a cutaway of the TPS and throttle shaft.


I found that my bronze bushing was pretty much dry (55K miles) and there was no grease in the groove. First I packed the bushing with a vacuum rated grease. Next, I drilled a small hole in the bottom of the TPS mounting hub, in case anything got past the throttle shaft bushing. Finally, the blue arrow is where I put an oring. IF you have the cajones to take apart your throttle body then you can put in the oring .

Also worth noting, if your TPS goes bad you can change it out with an OmniPort TPS and save over $400 vs. buying the whole frickin throttle body. You do need to modify the TPS so that you can rotate it to the correct S2000 position:


For AP1, the voltage accross the TPS should be .30V at idle position. It's in the Helm's manual.
