The RB, VQ, and VR are engines developed by prince/skyline engineers, and save for the VQ, have been exclusively used in Skyline Chassis. The VQ tech was shared with Nissan's original flagship, the Z (ie Fairlady Z); the Skyline being Prince's flagship vehicle, which became Nissan in the 1960s after a merger.

The RB, VQ, and VR engines have roots in the Prince tech L20 straight 6 engine . the first 2 GTRs used an S20 straight 6 setup, which most probably was a variation of the L20.

The L20, or L series engine, is considered the overall predecessor for R Skyline and V Skyline vehicle engines. On one hand Nissan kept the L20 in straight 6 formation developing it into todays RB, while on the other converted their L20 I6 into a V formation giving birth to Nissan's first V6, the VG engine class. Later on the VE was developed from the VG, after which Nissan developed the VQ for the G35 & G37 Skylines. The VQ with racing inputs most probably became the VR we see in today's V Skyline GTRs.

The S20 was not seen in later Skylines after its only two appearances in the C10 and C110 GTRs (Hakosuka & Kenmeri GTRs respectively), although the L20 saw further use in later Skyline Gens including a turbo charged variant. Therefore, the S20 may have been discontinued by Nissan due to lack of ability to handle forced induction. Moreover, the L20 is also the precursor for the FJ, SR, and CA engines used in other Nissan vehicles. In fact, all Nissan engines most likely have roots in the L series engine developed by Prince.

The C10 2000GT was the first Skyline to use the L20 I6 engine.

The C Skylines, R Skylines, and V Skylines are the only ones with GTR variations.

C Skyline GTRs: S20 I6, naturally aspirated (only time NA Skylines called GTRs & engine name didn't match letter in chassis code)
(C10, C110)

R Skyline GTRs: RB26 I6, twin turbo charged.
(R32, R33, R34); (ACP Offshoots: R35, R36)

V skyline GTRs: VQ35 V6, VQ37 V6, VR38 V6; twin turbo charged (ACP & NCP)
(V35, V36, V37)

G37/V36 GTT, single turbo; S & R tuned.

(I apologize for the profanity toward the end, I did not make the video. it is a great GTT setup for the G37, so I felt I had to share it)

R34 GTT sedan. Most probably a 25GT with a single turbocharger.


An R34 GTT coupe about to get the GTR body kit conversion. Not sure if driver will also add another turbo to the engine to make the full GTR conversion.

if there are skyline drivers out there who want to share their car's specs:

1. state the generation of your skyline (1-13, or if its an offshoot skyline generation).

2. give us the full chassis code with letter (denotes engine) and number (denotes body design), ie V36, R32

3. if its a coupe or sedan

4. tell us if its a GT, GTS, GTST, GTT, or GTR (depending on number of turbo or presence of carburetor); or if you've got a supercharger on it.

5. give us the horse power your machine is dishing out, at what boost (psi), and the third party tuner who did the work (if applicable).

I don't know this seems to be a fun way to get to know your own car and tell other skyline enthusiasts about it.

PS I'll see if I can find other Skyline tid bits later on.

You're doing it wrong.

the driver here put a dodge HEMI in the G35 Skyline and then placed a GTR badge on the front grill. rather than the GTR badge, there should be a HEMI badge instead, because the car is powered by a Dodge engine.

GTR badging by Nissan is done on Twin Turbo charged engines, I don't think the HEMI has any turbo. moreover, to be given GTR status the engine has to be native Skyline technology in a Skyline Chassis, like the RB, VQ, and VR; when these engines are twin turbo charged the GTR label is given to Skylines.

So therefore, neither is the HEMI native or original Skyline tech, and second I don't think there are twin turbo chargers on the engine. at least 2 reasons why there shouldn't be a GTR badge on that skyline; a HEMI badge like the one below is more appropriate.



in other words, the only way a skyline can be a GTR is if it has a legitimate skyline engine like a RB, VQ or VR. a hemi isn't an original skyline engine, plus GTR means a twin turbo has to be mated to the engine, and since only skylines can be named GTR, the engine should be a native skyline engine as well (VQ RB or VR.) so this is a skyline with a hemi, its not a GTR. instead of the GTR badge in the front, there should be a "HEMI" badge instead

Badging aside, he still is a hot rodder. Enough to put american muscle in a japanese car just to make it faster and have something rather unique. Perhaps the badges are to throw people off as to what's under the hood... I'd love to drive or even ride in it...

I do have a lot of respect for American muscle and the craftsmanship and creativity that comes with hot rodding; the focus for me here isn't really American tech vs Japanese tech, but more so the technicalities involved when badging a car a certain moniker.

I do applaud his creativity as well as American muscle (shout out to the Challenger Hellcat/Dodge Vipers!!), and yes he could be badging GTR to throw others off in regards to increase in HP over a stock G35, but once that hood shoots up everyone's going to know its a HEMI powered Skyline.

Your assumption that Gran Turismo Racer means twin turbo is ridiculous. I stopped reading after that.

thanks for the comment. if you have doubts you can check the engine codes for every skyline labeled GTR by Nissan (except the first 2), they all have twin turbo (designated by "TT" in the end). imagine sending in the R34 into a racing competition without the extra HP supplied by a 2 turbo system. also ask why are some skylines given GT, GTT, GTST, GTS nomenclature instead of GTR? I suggest you go back to the first page where this is explained already.

thanks for giving the full form of GTR (Gran Turismo Racer) I forgot to mention that, focusing too much on why its called a GTR

^ You sir are very disillusioned. There are so many other things that define a GTR than just the addition of twin turbos (AWD & Manual Transmission - except the R35, ATESSA ET-S, HICAS, subframes, floorpans, panel materials, interior, etc).

To even try to make the connection that adding aftermarket twin turbos to a Skyline makes it a GTR is absurd. Therefore, I will not be reading any of your "info" that you have posted because it was all fabricated under false pretenses.

Sir "floor pans" aren't going to do diddly without the 2 turbo powerhouse, as well as the ATESSA. Competitors would probably love that: "yes remove the turbo, keep everything else, and send your car to compete with us!" The heart of the beast is the twin turbo, it brings all those things you stated to life

The videos on the thread are proof what a well tuned twin turbo skyline can become, making stock G35s and G37s go head to head with other super cars even with all the trinkets

^ I never mentioned removing the turbos and keeping everything else. I said that the turbos are NOT the only thing that defines a GTR. I.E. just adding turbos does NOT mean said car is a GTR, even though you may be able to "go head to head with other super cars".

I'm done with you, because it is obvious the disillusionment in your head calls for professional help.
