Merci beaucoup ❤❤❤❤❤

That very nice at 13:18 made me chuckle. Great tip on the thrust clearance!

Guys, this is awesome info! Legitimately, as someone trying a home build an RB, these nitty gritty things like, how to check thrust clearance correctly, is VITAL information

Nice really good info. Let's see the pistons go in

Thanks for the upload😊. How do you choose which crank journal bearing for the applications accordingly with the crank shaft? and whar is the ideal tolerance?

Hey! Bearing selection is determined by the crank shaft journal dimension. while other factors such as the main line dimension come into play, the crank shaft size should tell you where to start. if the crank has not been ground i typically start with Standard bearings. and if they are too tight i run a HX +.001" More over the standard. or if they are to large of a clearance the .026mm or -.001" Tighter clearance bearing. if your crank has been ground you have two options for it to be ground to .010'' or .020'' i which case your machinist will need to measure a fitted bearing for an accurate grind. note some cranks shafts allow for .030'' of machining in some applications. but this is not common with the RB26. We may to a video on this in the future!

@@boost.factory Thank you so much for the infomation given🫡🫡🫡

So you were saying after measuring the connecting rod areas of the crank, that you wish they all measured so perfectly…. So for cranks you find that measure improperly, do you send that back to Nissan for them to fix it or send a new one? Or do you now have to fit the bill on a machine shop fixing them? Like is inaccuracy just a risk you’re taking when buying a crank, or will they(Nissan) make it right if you get one out of spec?

the other cranks i'm referring to are not cranks from Nissan but cranks from other machine shops or manufacturers that provide slightly less than satisfactory results. I Have never had a brand new Nissan crank give me trouble. Where i do have issues is when they are brought to me ( any brand or engine) and have been Ground .010" or .020'' and they are .0002" or more out of round or tapered and missing fillets. these ones do not get used and will be replaced if not repairable.

@@boost.factory awesome! This series is incredible! I’m going to be getting a 25 Neo motor soon enough here and rebuilding it with a few upgraded internal bits so this is going to help me immensely with everything! My first time building a motor as well so I’ll need all the help and info I can find! Hahaha I’ve got an excellent shop near me(bardabe performance; Austin tx) so I’m sure I’ll be bugging Juan to no end with questions as I go through it all!

@@boost.factory yes actually! I know it’s kinda asking for a lot but you did already reference it in another video, about oil getting trapped in the head and how to alleviate that… I know there are a ton of options like the BoostDoc dude sells those baffles, and then there’s the tapping a breather into the back of the head to a catch can and or recirculator, and oil cooler install, etc etc. As RBs’ biggest enemy is oil related, I’m sure an in-depth on “everything oil” would be really helpful. I’ve not yet seen anybody do anything as comprehensive as your videos are and the forums are so ancient and full of misinformation that it might be one of the only videos to properly address the topic. For instance like you can find a video of a guy showing you “oh yeah so I just tapped the back of the head and run this 90° AN fitting to this catch can/de-gasser, then it plumbs back into my oil pan. Well that’s all good and fine but that doesn’t help with the exact how to do it safely, and the WHY of making choices like where to mount the can, what size needed for potential applications, the importance of separating air/gas out of your oil, where and how to safely tap an oil pan and why to choose the location of tap over another location for instance.(I have two friends with wild amazing GTRs and one guy has his head tapped and returns on the turbo side, another guy has it on the intake plenum side… some interesting choices made there and I’m sure there are reasons but one should be preferable to the other and I’m not the person who knows why! Also like how different really is an OEM oil pump to a nice aftermarket… cause the price is like $1,000 different and there’s nothing priced really in between the two options… 300 or 1300; and then as you mentioned in another video also, like when doing an oil pump, how and why do you choose this or that spline option. Separate from above, I’m curious to know which I’m sure you’ll address in later RB26 rebuild videos, is why to choose which harmonic balancers and how/why to choose flywheels related to the balancer choices. I’ve not seen anybody go into depth about how the various choices affect your clutch strength/revving speed/capacity, etc.
