Thank you guys for your advice. Took me a long time with a few too many issues, but i did a coolant bypass first, then i switched out the black housing on the TB and I think I'm done. Idling is a little bit higher than usual, but it's steady. In the morning I'll drive it and see how it sounds and feels.

I did this mod a year ago. I had a friend port and polish the 4g69 tb i bought from ebay. The gains were pretty significant. Definitely one of my top bang for the buck mods. He did the coolant bypass and swapped the black box over and there were no issues. Your ecu just has to recalibrate its a/f ratio. You shouldn't have any rough idle issues though.

Can anyone tell me where I can by the 4g69 Tb for my lancer? Its a 2.4L. Also do I need to make any modifications to the TB for it to fit properly?
