Flash i just saw your post in the previous thread about flatfour's 5peed project. ill answer both your questions here.
SVX is not nearly as quick as your car. not NEARLY.
unfortunately the SVX is not twin turbocharged, nor is it turbocharged at all

. sad but true, man o man would it be a beast if it was turboed.
it only has a large N/A 3.3L H6 that puts out 230hp @ 5600rpm and 228 lb-ft @ 4400rpm. and whats most unfortunate is that its only available drivetrain is a tall geared 4 speed automatic (number one preformance draw back). lower gears suck. the car is a dog off the line. higher gears are quite good and its got amazing top end accelereation considering its weight and power. it was designed to be a luxary/spotr/GT cruiser. very very smooth on the highway, but because it is also geared highly twards luxary its heavy as hell. between 3500 lbs and 3700 lbs depending on year and options. considering its gearing, its weight, and its power the car can still get up and go surprizingly well. 0-60 in around 7.5s. and quarter mile is around ~ 15.6-15.7 @ ~90-91mph. not bad at all for a 230hp ~3600 lbs 4 speed auto. at regular cruising the SVX has an unusaul (unusaul for subies) 90/10 torque split. (which i wonder if that helps its high end at all with less drivetrain loss?) when pushed into a corner it atfirst suffers from understeer, but when the front wheels start to lose there grip and the car begains to plow all the power is sent to the rear wheeels and you get instantanious oversteer.
the SVX's weakesnt link is its weight and it tranny. its got an awsome (probly underated) engine.
please excuse my spelling and grammer, for its 3am and im not sober.
