Depending on how much downtime you're going to allow, I'd get another ECU to use temporarily because JWT will take their sweet time to get yours back to you. If you were swapping an SR20 in then you could use a DET ECU until JWT got yours back to you, but I don't know of any options for a GA16 other than using an OEM just so it'll run. As far as a CAI on your turbo, most people don't bother, but when I do mine I'm going to build a ram air plenum which will funnel cooler air coming in below the bumper, under the FMIC and up into the filter. I don't understand why people don't even attempt to get their filters to a cooler spot once they go intercooled turbo. We had this same discussion over at the SR20DEforum awhile back and a few of us thought it was at least worth looking into. So at the very least, I'd try to pipe that filter down low, and if you do a trunk mounted battery you'd have more room for options on this. I wouldn't do a turbo without the IC Andre, you can control your power with your boost level, especially if you spend the money on a nice Electronic Boost Controller. Although I don't know if I'd bother with a top mount at all.
