Question type: Car Customization

Is the new Nissan GT-R engine as tuneable and strong as the old RB26DETT skyline engine?

5 Answers

Time will tell but its early days yet in regards to strength, longevity & tuneability. Many of the well know Japanese tuners - & a few UK ones - are still learning about the engine & all its counterparts. Remember each engine in an R35 is hand built, so no two are the same & the advances that tuners have made so far have been well researched & tested before being released to the market. But it could mean that one engine takes an upgrade better than another. Its all a case of time & currently money, lots of money! Besides the early RB26's were found to be stronger than the newer ones found in the R34's! So will this be the same?

in response to your question about the GT-R motor. The VR38DETT is tuned from Nissan for MAXIMUM efficiency as a street-able and emission friendly platform, the motor is able to nearly double it's crank HP with the removal of all it's emissions components, but that would be a car that's for track use only and there's no guarantee that the motor will hold up reliably to those modifications, From my years experience with Nissan engines, and the fact that I work for them, I can say that the motor will be able to take anything you throw at it, as far as the drive-train/transmission, I wouldn't push that because it's internals are specifically geared and tuned for the most output from the stock motor, anything extra is just a tranny, transfer case, differential waiting to fail....... basically my advice to ppl out there that want to get more power out of their GT-Rs make sure the bullet-proof the drive-train first before doing anything, other than that, I stand by the motor with my credibility (which really isn't much on facebook)

i think you are about right on. the tranny in the new gt-r cant hold up when the car is in the race mode. as a matter of fact the gt-r's warranty is voided if the car is put in race mode and it is determined from the car was raced from examination of black box records in the car. the borg wanrer transmission isnt rated for the stock hp the gt-r makes. this problem is being fixed for next year though so the voided warranties wont happen.

"early RB26's were found to be stronger than the newer ones found in the R34's" - THIS IS UNTRUE The early RB26DETT found in the R32 GTR had a narrower oil pump drive at the front end of the crank and therefore would crap itself when rev-ed hard enough, that is the main reason why people tend to upgrade to the R33 RB26 crank when installing the N1 (or Tomei) oil pumps to their motors in the R32 GTR. There is actually a collar you can buy to add to the front of the crank to give the oil pump a 'fuller' drive contact area. ALSO, the turbos in the later R34 GTR N1 had steel turbine wheels compared to the ceramic (plastic crap) wheels found in all other RB motors....The steel versions can take much more boost without going BANG. As with the VR38DETT in the R35 GTR, the only main problem experienced by a lot of owners seem to be the 1st gear cog as it tends to shit itself if used too aggressively in 'launch' mode.

The only thing that was lacking with the RB26DETT was the capacity and oil issues up the top end, once you upgrade it with a domestic RB30 bottom end (forged) or the more expensive JDM option of the OS RB30 deck plate / sleeves (to keep the RB26 engine numbers so no problems with rego !), matched to a decent single like a GT3582R for response or a T04Z (or even a T51 SPL if you're insane) for outright top end, this motor is invincible. It's capable of 450+rwkw all day everyday. Considering the RB-series of motors being late 80's technology, it's done well and it's proven itself over the years.....Remember, no V8 shit boxes could keep up with Jimmy and Skeife around the mountain and the RB26-powered R32 STILL holds the Bathurst 1000 race record ! But then again, you have this motor to blame for the birth of our V8 Supercars.....bloody losers (cant beat them, ban them.....real Aussie attitude)
