white smoke

Howdy y'all! I'm new here, but not new to Impreza's. I'm the original owner of a 2002 WRX grocery getter! She's 60,000 miles young! :tongue: Within the past 5,000 miles I've begun the process of modifying her. Currently she runs tasty M1 TDT 5W-40 as of the last oil change, but unfortunately...

02 WRX 2.0 VF39 swap with 99,000 miles, sti pinks had a dyno appointment today and after the first pull (only 191whp) started pouring out white smoke of the tailpipe. Smells sweet like coolant. Guessing head gasket or turbo????? Any feedback!!!!!! It's my only car so I need to fix it asap!
