Yes they are both 6 cylinder, a 325 is a 2.5L I6 that puts out about 184hp and the 330 is a 3.0L I6 that puts out about 220-230hp (cant remember the exact number). In terms of driving, a 330 will be noticeably quicker than their 325 counterparts. 01-08-2010, 05:08 AM #4. roverT604. Member. Join Date.
A stick 328ci will keep up with a 330 until you get to higher speeds (80+) With performance mods, a 328 will SMOKE a 330 and will keep up with a 330zhp. A simple 3.46 differential on a manual 328 will make the 328 as fast as an auto 330. With good intake/exhaust and software added, you can keep up with a ZHP.
