I've ordered the r tech kit . Should be here next week
Do you have to loose the air con? As doesn't it mount to the original cooler?
Air con can stay. Air con and coolant rad screw/bolt to the standard intercooler, so you will either need to leave this in place, or smash our the core and just use the end tanks as brackets
You will need to mount it in front of the A/C rad but behind the crash bar, and some trimming of the crash bar is to be expected.
