I would think that the V6 swap would be better for daily drivability and reliability in the long run than a turbo kit. unless youreally like "tweaking" because most add on turbo kits you always have to tweak SOMETHING. Most turbo cars you always have to tweak SOMETHING you just can't leave them alone. i've had enough DSM's over the years to know better lol. once you feel that boost, it's never enough. better intercooler, bigger turbo, more fuel, bigger turbo crap now the turbo won't spool until 5k rpm so let's throw a 50 shot zex on there to get the turbo spooled faster... it's never ending. if it's a toy/track car by all means go turbo. if it's a daily driver from my personal experience i would recommend a V6 swap... or unless you're particularly attached to your car (because it would not be a small project by any means) may better suit you to just get a new car with more power from the factory. i've always wanted a bug-eye wrx wagon theyre just hard to find around here that aren't abused.
I had a V6 Probe GT almost 20 years ago... that car was a blast. It was basically stock with a few bolt-ons and it wasn't "fast" (low 15's/high 14/s in the 1/4 mile) but "felt" way faster than it really was due to gearing and power band. I bought that car with 40k miles and beat on it daily, i was a kid back in college and didn't "think" lol. poor car had a really hard life... but I sold it with 170k a couple years later and never had anything break on it.
