88, st165, 1st gen. jdm w/ +-50k
aprx.16, 1.1 bar
about 10k @ 1.1
k&n oem replacement, MBC, intercooler pump constant run, bigger heat exchanger for ATW-stock core, primary cat is gutted.
no boost related failures yet, was missing because of old plugs but thats it.
this car is smooth and fast, i use Redline 20w50 synthetic oil i recommend this for all turbo cars, its designed for them.
