The intercooler they supplied with my kit is a tad small, but it is made to fit in the lower opening in the stock facia. Mario replaced his Front end with the Zefiro body kit, and also wanted an more efficent/bigger intercooler to fill the space.
Apline claims that the intercooler they supplied was good for a 50% reduction in intake tempatures....however they do not state what that temp was...or what the temp was lowered to. I'm in the process now of working up 2 air temp meters...one before the intercooler, and one just before the TB. That way I will be able to monitor boosted air temp, and the intercoolers efficency.

Random is right, I changed the front of the car with the Zefiro kit and the position and size of the Alpine intercooler is not exactly the best for where I want to get. I bought a nice 3inch deep 6inch tall, 24 inch wide which is perfect for my kit and efficiency (temp and pressure drop) is very high. I want to reach 14 to 16 psi and therefore need a better intercooler, I will also be injecting water to reduce detonation. I am running 12 psi quite well now. Our fuel is not that good so we need better intake cooling to avoid detonation.
About the wastegate I dont know why they are different. I have talked to Randam and it seems his kit has some differences with mine. Remember mine is a MAP system. The wastegate allows you to adjust your boost but once you set it up you need to get off the car to adjust it. The boost controller allows you to change your boost from the inside by the push of a button or by turning a knob. In my case I am running 8psi all the time (even with the controller off), 12psi on the second setting (button) and have not used the higher setting yet which will automatically turn of after a given amount of time say 30 seconds.
