I saw two of these racing up and down the street I work on (Nissan Canada head office is right around the corner from my office). They sounded pretty good! Honestly, from my window I would have been hard pressed to know it wasn't just a couple of 370Z's if I didn't know any better.

This argument is worthless because you have no information to substantiate that. Unless you have seen BMWs simulations and FEA you have no idea. The simple fact is that every modern BMW engine with higher stock output than N55 is a closed deck design. Pretending you know why is pointless.

TBH, fairly certain Nissan has zero expectation that this will be some class winner, but its main goal is to offer cheap way to get 400hp with a 6 speed in an attractive sports coupe, and this does that. No doubt we will see these at the next takeover event doing donuts.

Diesels generate excessively high cylinder pressures thus need for closed deck blocks. Most importantly, BMW is in the business to make money thus parts bin sharing is the norm. |

That is true, but it's also true that you have absolutely zero knowledge of the reasoning behind their decision. We can only guess.

https://f30.bimmerpost.com/forums/sh....php?t=1171642 I don't know how much clearer this needs to get for you. BMW wanted to keep engineering and manufacturing costs down and designing and making engine blocks is crazy expensive. Instead of having to develop two separate blocks this time around, they developed one that can be shared between the diesel and gasoline inline 4 and 6 B series motors. Since diesels have high cylinder pressures, the block needs to be closed. Simple as that and why they did it. |

Yeah... except everyone I know or have known with one literally can't get their shitbox out of "reputable" shops. Still a huge difference between a supercar and a JDM time bomb. |

The Nissan VR30DDTT is an evolution of the VQ block But since we're on the subject of cost cutting, it uses the same open deck design, as opposed to the closed deck VR38DETT in the GTR BMW saw that the old N series design needed some improvements so the changed to closed deck for the B58 and S55 variants While also being able to utilize it on their diesel platforms Win win for them |

The open deck N54 and N55 blocks have shown that they can handle massive amounts of power beyond stock. Yes, the B58 closed deck block should hold more power, but we're talking the difference between one handling 600-700hp vs 800-900hp. How many people are really going to venture down that path? Once you start pushing lots of power above stock, the mechanical weak spots in the N54, N55, and B58 are the pistons and to a small extent, the rods. They all run hypereutectic pistons. They all can crack, break ringlands, etc. The N54s and pre-2013 N55s use cast rods. The 2014+ EWG N55s use the S55 forged rods. The M235 and M2 N55s alos use a forged crank. The B58 has a forged crank and rods. The limiting factor in the "365hp" with the N55 was not the long block. The limiting factor was the intercooling followed by the the turbo size and fueling. It has NOTHING to do with the strength of the short block at all. Add a larger intercooler, a bigger HPFP, and larger turbo, and you're in business if you want 500-600whp. The B58 is obviously easier since it already has a bigger turbo, better intercooling, and fueling (especially the later B58s). Even then, it will need a larger turbo to get 500-600whp and a newer HPFP if it's a first gen B58. Circling back to the Z, the open deck VR30TTs have been pretty dang reliable when pushed well beyond their stock power. Is it ideal for a 800hp+ build? No. But for 450-500whp/wtq, it's just fine and will be plenty fast for the street or strip. If you want a faster car, buy a faster stock car. Life is way easier. So many on this site think that having a 600whp B58 is simply a tune and ethanol and it's fire and forget. Nothing could be further from the truth. None of those cars run perfectly and need constant babysitting. Same goes for 600whp N54s and N55s. Hell, even Stage 2 N54s, N55s and B58s can have issues depending on fuel grade, quality, aggressiveness of tune, etc. It just gets worse from there once you start adding mods.

Not surprised at the reviews. I mean, regardless of the new engine and suspension tweaks its still running on a fairly front-heavy 20 year old platform.
That's what is limiting it vs Supra IMO. |

Where available, manuals are no cost options in BMWs and it's been that way for a long time. My 6MT M235 was no more than a 8AT AND I deleted the moonroof too which I didn't get any money back for that. In the end, I'll get way more money for my 6MT, no moonroof, LSD equipped M235 than the garden variety 8AT and moonroof equipped M235s the vast majority have. Manuals will ALWAYS command a higher resale in sporty cars compared to the autos, even if the autos are faster/quicker. I wanted my M235 to be the lightest, most connected, version of the car I could get. It weighs over 300lbs less than a comparatively equipped M235x. That's huge.
