s15 gt28r on ca18det help

[s13_st]

Need help clarifying. I know that I need a compressor in/out adapter and I was wondering if this is what I need. http://www.frsport.com/DIF-10006-T28-Turbo-Reclock-Adapter-w--GT28R-Style-Comp-S13-SR-Upgrade_p_13233.html

No. You need one of these if you want to run the stock inlet trunk.

On the outlet you can use the stock CA18DET adapter.
