Well this motor is rough and I can totally tell it's not near as balanced as
the 2035. This motor has tons more top-end. I'm sure we could all guess
that. And ofcourse not as much low-end, but since the car is much lighter, I
don't really notice the lack of low-end. Plus it's not a daily driver, so I
drive it really hard. Most shifts(after it's fully warmed up) are at 7k or
higher(it doesn't want to stop there, but I make myself do it). All in all,
it's very fun, but when it comes time for a rebuild, i'll do the 2035 again,
no questions.

How do you like your new 1984cc with 260-276 vs your
old Jetta motor with the 256's? Different kind of
power?
just wondering
