RB's are overplayed ricer fodder, and has no more potential than the VG30DETT just a higher initial cost
IMO RBs are a great nissan motor, and a great way to make space for power under the Z's hood. They are easier to work with and have more potential then a V motor hands down. Dont get me wrong I love the VG motor, and it's solidity but for those who like to do their own work on the car, RB will make the work easier and less costly.
um, no
the RB is a very capable motor as wal the L6 it replaced, and the VG30DETT is also very capable as was the VG30ET ir replaced, nissan has made some greatmotors and these are only a few of them, but ultimately, the old saying is true, there is no replacment for displacment, the VG moves aproxox 15% more air per revolution, for the RB to make the same power it has to work harder, both engines need the same mods at abotu the same points to make power, the fuel injectors and turbo's are the first obsticle in making power in both engines, both are capable of making north of 500 whp wiht only those mods but the Rb has to spin faster to move the same amount of air to make the same amount of power
lets say you wanted to make a 500 whp Z32, you coudl either buy a $5k TT then spend $36 on turbo's and injectors and have $8k invested in yur 500 whp car or you coudl buy a $3k n/a then spend $3k on an RB26 then another $3k on turbo's and injectors to have the same 500 whp except you have a lot mroe work to do and a lto mroe downtime while doing so and now have $9k for the same result but with more front weight bias and a higher center of gravity, but yes, and RB makes for more workroom when it's done, oh and if you are hiring the work out the labor bill for the RB will be a heck of a lot more than the simple upgrades to a TT
