i have an s13 with sr20det with a t28 turbo...

my first problem is it is breaken up on high boost ...7-10lbs is fine but 11-13lbs.. it breaks up...like it is not getting enough fuel at high boost...

my main concern is after driving for 15 minutes or more.. then sitting at an idle it starts to blow white smoke and when i rev it really blows out... it only smokes for about 2 minutes and stops..the car runs perfect though ... never overheats or anything..

please i need help before i fuck something up... thanks bobby
