That was a quick install! I wish my intercooler would go in that quickly. Did you use a air/air IC or a air/water unit? How much did it decrease your EGTs? Any plans to adjust the full load of the IP? Any idea of the pressure drop across the core?

i used a air to air unit. its the old one off of my Eclipse. to tell you the truth i cant tell a difference except for a little more turbo lag i dont have anything to monitor the engine with so i cant say much more then what i feel in the seat.

if you have a stp by step that would be awesome. I have an intercooler, but no idea where to start. how hard was it to disconnect the turbo and intake? did you use the stock intake? how did you get it all hooked up? I'm all ears and have a ton of questions

the turbo and intake arent bolted together. all you really have to do is (simplified explaintion) you loosen the bolts on the compressor housing, then turn it so it faces the passenger side of the car, then using silicone couplers and 2 inch pipe you route from the turbo to the intercooler, then back out into the intake using a silicone coupler on the intake as well.

did you have to move the intake at all to make the turning of the turbo possable?
