Hey mate, i had a KKR 430 on my rb20 and it pulled 297.5hp atw, Great fun to drive with cause it kicked in hard, but it is laggy. I am selling my turbo kit right now as i have put in a 26.
For $1200 ONO plus shipping ill sell u my kit which comes with:
-KKR430
-Highmount manifold
-External wastegate
-Cooler piping (no BOV)
-3" Dump with near new o2 sensor
-Oil line (custom)
So all u need to get it running is a BOV, FMIC and about a couple of hours to fit and weld up the dump to ur exhaust.
I bought everything new and i have only had it on the car for about 6 months. The turbo it self is in great condition, and has had the gate welded shut.
Drop as a msg with your email if u want to see any pics of it all.
