Everything I say applies to the 2.0T GTI and K20 Civic

The test data indicates 0-60 in 6.6 and 1/4 mile at 15 seconds for the SI, 0-60 in 6.3 and 1/4 mile in 14.8 for the GTI - this is repeated in almost every magazine review I've read

the GTI is always slightly faster, but then the Civic comes in and handles better, usually posting a faster track time, higher skidpad and higher slalom

the GTI really shines when you chip it - you're looking at 250 hp/300 lb-ft of torque (from 2000-5000 rpm, no revving to 7000 rpm just to reach peak torque output)

however, the GTI is crippled by its chassis layout - it will never be able to handle the way an SI does.
