4N Motorsport on Instagram: "First start of the N55r26 in the M4 GT4 build. I’ve got a few more things to button up and she will be ready to test! Notice the mechanical S55 water pump is gone. I wasn’t joking. N55r26 is now in the GT4 build 😂🔥🤘 #bmw #n55 #m2 #m3 #m4 #racing #performance #135i #s55 #bmwlife"

4N Motorsport on Instagram: "Sound clip from yesterday! This was a flyby in the same area. Still low boost/low timing 18psi pull at 6,000ft elevation. Posting a few more of these videos in different locations this week. Can’t wait to go back on a high timing 27psi map. Will be over twice the HP soon! #bmw #bmwm #racing #performance #f1 #n55 #135i #335i #m2 #m3 #m4 #bmwlife #bmwgram"

4N Motorsport on Instagram: "///M Monday! Some sound clips for you guys and an update on the N55r26 2.6L N55 engine! So far this has been the most fun I have had with an engine build in a project car. It’s still on low boost while I test a new tune. In this video you can see how responsive it is. This is due to less stroke and a major reduction in reciprocating mass. The throttle response feels similar to that of a N/A S65 engine. There is less torque down low below 3,500rpms but the way it pull

老款H6用的这款2.0升自然吸气发动机，型号4G63S4M，来自沈阳航天三菱，很多厂商都在用他们供的这款机器。从技术角度来看几乎没有先进性可言，不过皮实耐用倒是很明显的优点，很有吃粗粮干粗活的潜力。#二手车搬运工 #二手车 #好车不等人 #抖音汽车
