R34 Gtr True Power

[Turbo Piston]

I have heard that the R34 GTR was released claiming it had 206 Kw. But when they places it on the dyno, it actually had 244Kw, is that true?

Or 280HP but truly had 327 HP!?!

206kW was the "gentlemans agreement" between all jap car manufacturer's. So cars like gtr, evo supra's etc all will quote 206kW. But guess what...

I read that too, on Wikipedia tho and I don't really count Wiki as solid info.

The gentleman lied! ?

would seem that the gentlemans agreement was more to be 'kind' to the opposing car manufacturers; Japanese culture is very different to western business and seems to include more morals and integrity.

Same as the new GTR; no-one knows how much power it really makes as every engine is different.

An RB26 would definitely make over 240kw standard; thats without any mods

[Bakes]

Yes, it definately has more power than 206Kw stock. Its more like 260Kw I think.

I think fully stock the R34 GTR would pull ~180Kw at all 4 wheels.

^^Thats about right.

i'm sure someone will correct me here, as i've never owned a GTR (or looked inside a standard one), but i read somewhere Nissan were kind enough to mark the restrictor in the boost control line so it was easy to remove, thus returning the engine to it's intended power.

[Turbo Piston]

Interesting, I wonder if that is true!

[Beer Baron]

yes the boost restrictor is marked on the line. I have owned quite a few GTRs now. 32, 33 and 34 and have had a standard 32, standard 33 and standard 34. I would agree they do have more than 206kw at the engine standard, but I don't think it's 240 or 260, I would say around 210-220 for 32s about 220 for 33s and about 230-235 for 34s. but what they really did was add a couple of basic resitrctions to bring the cars fown to the 206kw limit. so with a free flowing exhaust and 4 pounds more boost you get great gains. an extra 30-40kws just with those mods.

Safe to run without the restrictor on a standard car?

[Beer Baron]

well that's kind of an individual choice! but personally yeah I think it's ok. providing you get the car checked on the dyno when you remove it. check the AFR, knock, and boost level. providing the boost is not going past 14psi and the AFR is ok and there is no knock then go for it. enjoy some free power. just be aware that any 32 with standard turbos is a bit of hit and miss. some will blow a turbo even at standard boost. some will live for years and years on 15psi with no problems. so if we are talking R32 (or even R33 really) then do it at your own risk!

[CHO50N]

Nope talking 34! Mate has one that is dead stock and after reading this thread was thinking about taking it out.

[Bakes]

Yep Fine, as Baron said just get the AFR's checked on a dyno.

Best bet however is to fit a boost controller!

[Turbo Piston]

What exactly is a boost restrictor?

[pepe lopez]

Ben at RacePace put my 100% stock R34 GTR on his dyno and it made 211 rwkw. I fitted a HKS cat back and boost has now hit 1.2 bar, so I'm guessing it makes a bit more now.

The 211rwkw figure was made with stock airbox and panel filter, shitty compliance cat, stock exhaust, 180km restricted. The motor had 59,000kms on it.

[Turbo Piston]

rwKw? What about on all four? How much did it make?
