I have decided on going the 1J route and ditching the 7M when I get my bonus check in the fall. I have a place to do the swap, but are there any shops or fabricators that do upgrades on the 12a's that come with the 1J? I have heard mention of putting the MKIV 12b's, mitsu turbos, or the EVO turbos on. Anyone in the state that actually does the installs/fabrication required? Also, approx how much would this run? I have done searches but all I gather is speculation from people thus far. Thanks in advance...guys and gals!
