It would be an upgrade, your car is more along the lines of a modded Mk3 in performance (and they kinda have the same body lines B) )
1986 Porsche 944 Turbo:
0-60: 6.0
1/4 mile: 14.6
1989 Toyota Supra Turbo
0-60: 6.6
1/4 mile: 15.2
1997 Toyota Supra Turbo
0-60: 5.1
1/4 mile: 13.6
I'm unsure of the Porsche's suspension system, but I know the Supras are fully independant, and handle quite well, put some sticky meats on em and they will hold as well as most sports cars. Supras are easily as plush as a porsche, they ride smooth, the interior is nice, and they've had climate control since the 80's as well. About the only thing I can say is look hard on places like autotrader.com and go scope one out and take it for a test drive. You'll be the one that will either fall in love with it or hate it, good luck
