iI was wondering if its worth getting the gti or civic si I love tunning just dont which car is better to get for this and which would probably be faster in the long run and stock

Which model years are you looking at?

There is both an old and new GTI 1.8T engine, and old/new Civic Si bodystyle and engine.

The first 1.8T (came out in 2000) had 150hp and 155 lb-ft of torque; the updated 1.8T has 180hp and 173 lb-ft of torque.

The late 1990's Civic Si coupe was a 1.6L, NA car with 165hp and only 111 lb-ft of torque (less than my Golf GL :D), although the new Si hatch got bumped up to 2.0L with 132 lb-ft (but same hp).

So, by comparison, the GTI 1.8T is definately faster (and dare I say more refined) stock. The Honda would rev well in the high range though, and if you slapped a turbo onto an Si, as well as the usual bolt-ons, I'd think it could be faster than the GTI ... probably lighter than those husky mk4s too.

Everyone else here is probably strictly Euro, I would be too except I used to drive Hondas in high school, so I still respect them - especially the Si.
