Indeed!

More that in the end, it doesn't matter to me if this does end up failing, but i'd like to be positive about it, especially when one company like this is banking a fair bit on it working out lol... My gf is getting herself a skyline soon anyway for me to modify, so it's not like i'm going to be hard up for a fun car hah

not to distract people from the Boost discussion, this same article has this info about n52 displacement/stroker posibility:

“Only a marginal increase of the displacement is possible (for the I-6 engine). However, an increase is not planned,” Welter says. “This is consistent with our Efficient Dynamics program and philosophy, which improves performance and at the same time reduces fuel consumption.”

so 3.2 n52 means no MPG

As far as i've read, the 3.2 kit doesn't change day to day driving, only if you hammer it lo
Ed: and 3.0 to 3.2 is way beyond marginal haha

If you can't afford a 135i upgrade you can less likely afford to gamble with with a kit like this. Makes no sense.
