Heat Resolution Explained

So it's been almost a week since the car has been driving with the absence of any over-heating with A/C on full blast. I really wanted to make sure this problem was resolved before posting about it.

What's been done,

-Reverted back to using the Internal Waste Gate rather then the use of the Tial 38mm External. With this, the stock Exhaust Manifold went back on replacing the HAFE.
-Stock Heat Shields back in place
-Switched from Mishimoto Radiator to a OEM Radiator [This was done for space issue's]
-OEM Condenser Fan is back in place.


Zero heating problems. With A/C on at all times! ( This is with the front bumper back on )


Here are a two interesting things I found along in the process.

  • Evo III 16G while authentic from the intake side, has a Ebay Exhaust Housing side, which is why I couldn't bolt up my 14b Actuator to it. If you compare a Ebay Evo III 16G to a genuine one, you will notice the Ebay actuator is actually adjustable. Also, where the tip meets the flapper lever is stick out way farther then a OEM one. I had to unfortunately bolt up my spare 14b Exhaust Housing to my 16G in order to make this work. [I'm guessing the previous owner replaced it with the ebay housing to minimize costs]
  • 02 Housing that has been on my car the whole time was from a 1st generation dsm! And what made matters worse is that it was bolted on with only 1 bolt! About half an inch of the 02 Housing was not sealed flat against the downpipe. So the good news is, I fixed a horrible exhaust leak I had no idea about, and quickly grabbed my spare 2G 02 housing

So after many days of rigorous testing with this setup, on hot and humid Miami weather days, I must say. The car has never ran cooler in the whole time I have owned it. And that's being said with the OEM radiator over the Mishimoto!

Average coolant temps on a 90F day with around 80% humidity and A/C full blast is roughly 183-193F. The car pulls harder then it ever has, and no longer feels sluggish during hot days. Over all, I'm very pleased with this current setup. 


At a later time, just to further help improve the cooling even more, I will be ceramic coating the Exhaust Manifold, 02 Housing, and wrapping as much of the down pipe as possible.

All in all, what I think really helped the car from over heating with the A/C on was the addition of the A/C condenser. The external was keeping me from being able to have a decent one on. Sure I could have replaced the dump tube and had it routed a bit different, but I honestly like hearing the turbo spool again. :)
