Funny story, I had an 80s one, I legit bought it because
@Rat Speaker (rip my nigga) told me too.
It had 450K+ miles on it no paint and was 700 dollars. Next thing I know it was coming home.
So after a tune up, I got the OEM turbo manifold, a wuhan war whistle and reflashed it.. 5 PSI then fuck it, intercooler (DSM) mounted where the oem airbox was and 7 PSI. Got some bigger tires and rims outta a junk yard, some wal mart speakers etc.
Sold it to girl I was seeing at the time for 2500 Less than I put into it and cost. It's ugly as fuck but she's still on the road.
Volvos can move, some of them, the 60/70R series was quick and has an AMAZING gauge cluster (also the leather was baller) but being 5 bangers sound like a sewing machine satan used, when he was high.
