N55 vs. N54 In the market for an E90 again.
Alright so I had an 09 E90 with the N54 engine and loved it. Now looking to get back into it but was wornder maybe to go with the N55. But the most important thing to me is tune-ability. The N54 sure has ALOT of bang for your buck mods.
What have you guys noticed with the N55? Can it put down the same power for the same amount of m/oney? What upgrades have you guys done? w/m, tune, dp, exhaust, big turbo??
