Toyota Carina Coupe GT-T TwinCam Turbo

Performance:

August 1997, 1290kg, 276hp@5800rpm/1.2-1.25 bar

interval, time, [gear at final speed]
0-50km/h 1.9s [I]
0-80km/h 3.6s [II]
0-100km/h 5.0s [III]
0-120km/h 6.5s [III]
0-160km/h 11.0s [IV]

and for the US viewers pleasure:
0-30mph 1.8 s [I]
0-60mph 4.8s [III]
0-80mph 7.4s [III]
0-100mph 11.1s [IV]

Top speed: 240km/h=7000rpm, will not try above that... With larger tyres and Supra W58 gearbox about 259km/h / 161mph [Japanese market cars have had a governed top speed of 180 km/h / 112mph. Check here how to disable it ;) About 200km/h were quoted in a German book for a Carina GT-T in stock form.]

simulated with RevAnalyzer, part of RevPro package:

   Blue=stock except no cat, [email protected]
   Green=limit of stock turbo, fuel cut removed, [email protected]
   Red=what I have now, [email protected], intercooler, T03 50-trim, 460cc/min injectors.
   Test weights 1290kg for current setup, 10kg less for stock setup 
   = almost full tank + me

Braking
Average deceleration from 60mph ~1.1g's
(fade is the problem, not initial performance)

picture from the days of cheaper gas.
Fuel consumption
Average for me 13.3 l/100km, 17.8 mpg
city 11-20 l/100km
highway 8-18 l/100km
economy competition 5.45 l/100km (220km, 59km/h average speed, 100km/h top)
Japanese test 8.9 l/100km, 26.4mpg
German estimate 8-16 l/100km
