RB26 Power-readiness; Fact, fiction, and BS.

[bobbo]

Oh and about the clutch thing. It's all wheel drive. Way way way more stress on the clutch when your wheels don't spin... Much

Fact. I die a little inside every time I do a launch knowing all the stress it's putting on my OSG. Do it right the first time so you don't have to do it again anytime soon but I hate beating on good gear.

Well, hold up guys. I don't think 650 should be the maximum hp range for the GTR. I say it's optimal. The car can really perform to it's full potential. Want more? I don't see why not. What is too much, you ask? Well, i think those RIPS tuned (New Zealand tuner) RBs are ridiculous. 1000HP out of 2600CCs (even stroked to full 3 litres...still) and 6 cylinders...Nah... It's a doofus tune.

600range. Mid 700, LOW 800. To me, those are the boundaries, in terms of necessity, for the RB26 engine.

Furthermore. What i heard earlier about in-line performance and cornering. I disagree that the GTR is only good for track performance (although track performance is true performance; real performance, the only thing that CAN be called performance, and what makes a performance car a performance car).

It has in-line speed, and it's an all-rounder. A true driver's car. A serious machine .

@bobbo: As for said "tinkering" required for smaller engines to get power. I don't think it's required in every example of a "small" engine. It's whether or not it is built from the factory by the manufacterer, to be power-ready.

It's about Power-readiness, as i refer to it as. It's the main focus of this thread i made , after all.

The RB26 doesn't have it, in ALL aspects. However, im confident that the R34 GTR is the best candidate. It's the most refined, and most complete of the Skyline GTRs. It by far has the DIRTIEST transmission . That Getrag 6-speed is a very, very nice transmission.

Also, in regards to turbo lag, someone mentioned it earllier, i think it was hozer. In the GTR, it's strange. It's some sort of turbo-related phenomena that not all engines experience. It makes you want to take apart an RB26 piece-by-piece and inspect it, . It's...Not turbo-lag. Rather, something i would call turbo "response"...it's quite amazing. Usually, turbo lag, as we know it, is the turbo spooling up when you put your foot down. You can feel it!
On the RB, on the other hand, it's more like an RPM range where the turbo simply kicks in.

It might seem like it's the same thing being described in different words. It's hard to explain...

The supra, despite having an extra 400CCs at it's disposal,and despite having a twin turbo set-up just as the GTR (although it's sequential), it isn't fortunate enough to experience this. Well, the engine, anyway... You see Supras with with 60+mm turbines, even worse, something like a 72mil, and they take longer to spool up than an M134 gatling gun... It's a shitty, shitty, CRAP-ASS driving experience. I hate it. The GTR is more like a...Jet? I don't know how to quite describe it. But i hereby say the GTR has turbo a turbo-response range. As do other examples of that forced induction experience.


Say what you want, it might sound like i've been...eerrr... Under the influence , but i assure you. It's not the same experience. The RB is SMOOOOOOOOOOOTH, and streetable.

Lag?????

What is this....lag, you speak of?


Anyway, you my friend need to do some serious reading, all the info you are looking for is all over the place in here. I spent 2 years on here and read all I could before I got my car. Put in a better clutch, steel wheels on the turbos, Nistune, Z32 mafs and a set of 750cc squirters and you have a 500 whp monster that will decimate most that get into it's path. Nothing under $250,000 off the showroom floor will hang with it. Alot under $400,000 will be sent to the showers too.

Pretty damn good for 25 year old technoledgy.......

How much does a new GTR cost?

Yeah, wasn't necessary to reiterate something i pointed out myself earlier. I asked for more info, and Mr. Cortexx was kind enough to provide me with some very nice and substantial reading... .

Also, Y'know? Turbo lag? . Big turbines tend to take time to spool up.


And steel impellers on the turbines...? WHA? I know the stock ones are ceramic. So you're running stock turbines? And producing that power?

[knate]

n1 turbos have steel blades

Lol....

Im packing a tad more than stock turbos.....check my sig. One thing that will hold you back is the bulk that comes with an R34. Putting R32 gears in an R34 will help out a heap (just like Nissan did with the R35...gearing). A set of N1 turbos on any of the RB26s will give you the potential to run as fast as 130mph in the quarter.....more than enough to stomp alot of arse.

With R34 GTR they use 4.111:1 R33 GTR V-spec diffheads. From what I understand, the reason behind why they use the R33 GTR V-spec diffheads is due to the active rear LSD on R34 GTR V-spec.

Some with R32 GTR fit stock R34 GTR gearbox (supposedly can buy conversion kits from Japan) which is said to have closer 1-4 gears and taller 5th, 6th gears and works with the 4.111:1 diffheads. This is matched with the Mines demo car spec engine with HKS 25/30 turbo's, etc. Seen 2x R32 GTR's with this conversion.

With GTR you have different models from factory that have different specs, then you have the Nismo specials (including N1 GTR which has a Nismo engine, etc) which are still factory but tuned with upgraded clutches, engines, etc.

This is using the R34 GTR lineup -

GTR (no undertrays, etc)
GTR V-spec (victory spec or basically a watered down version of a N1 GTR with undertrays, active LSD, etc)
GTR V-spec II (base model that's used when making Ztune model and N1 GTR)
GTR V-spec II N1 GTR (no rollcage, bigger turbo's, oilcoolers, upgraded factory engine, etc)
N1 GTR racecar (for N1 endurance racing teams and is basically a stripped out N1 GTR with rollcage, tuned engine, etc)

Nismo specials -

S-tune (street / trackdays, 400hp at engine)
R-Tune (racetrack, 460hp at engine)
Z-tune (racecar for the street, but without rollcage, 500hp at engine)

Stock R34GTR produces around 330hp at factory (N1 GTR should produce more hp due to bigger N1 turbo's). With boost up mods stock R34GTR engine can produce around 420hp or slightly more at engine (depends on mods you use, etc). Sometimes you get a good car that produces more hp than others at factory (I think due to stronger internal wastegate springs, etc) and when boosted up produces more hp.

From what I understand, Cobra is a Ford racing special??? That means it would be compared to Nismo specials.

That is a great point that I didn't pick up on myself, good catch !

BTW skym , you have 120635 % more threads that contain "I see" as the reply than the second place poster (who happens to be a slightly retarded squirrel that lives in the south pole that is constantly complaining about it being "Icey" )

[SFitter]

I've owned a bunch of mustangs including an 03 cobra. Theres no doubt the cobra motor and tranny is more robust stock compared to that of a rb26 gtr. The problem is no traction with those cars. The minute they make big power 1st and 2nd gear are spin. You have to use slicks or dr's on a well prepped track to make them work. On the street good luck beating a mildly upgraded gtr from the lights. Also keep in mind a 400whp gtr would probably run a 500whp cobra pretty even. You can always build an engine to make big power but you cant change the design of the car. Also you dont just slap a new blower on a cobra and call it a day. They need exhaust, intake, tune, clutch, tires, half shafts, input shaft, fuel system and IRS upgrades etc. The GTRs seem to go fast without sacrificing drivability plus no carrying around rims and tires and switching back and fourth to go to the strip once in a blue moon. I sill own a blown foxbody as well so no favourtism on my part

^true story.

[Prenihility]

Yeah, i guess, in the end. What i'm trying to say is. I'm shocked at the fact that the car(s); this goes ESPECIALLY for the R34 GTR, came with power in the 300 range (the 350 mark for the R34), and retailed at such a high price.

For the R34, they should have included a nice mid-high 400 HP range. I'm saying... 480. Either that, or low 500. 520.

It would have been nice for the folks spending over $60,000 in 1999...

Or at the very least, put more effort into this whole subject of "power-readiness".

Things like the oil pump shouldn't replacing in a car that expensive, if you want to pursue more power, given the fact that it was underpowered to begin with, in comparison to the price.

Although the NSX...is a whole other nightmare. Used NSXs (NON Type R models, mind you) go for the $60,000 mark.

Which is just f***in' NUTS!

You'd have to be a loon to spend that money on a car like that. Not to mention, one that doesn't respond to mods well, and is balls-expensive to work on.

[NismoS-tune]

You can buy a 2013 ford shelby gt500, loaded, for $65,000 nowadays. That thing has 662hp and is nuts. Year it doesn't have silly paddle shifter nor is it an autobot that can nearly drive itself but it's a lot of fun.

I don't think you have the right mindset. Power isn't everything.

The R34 had "only" 300hp because it wasn't worth changing an engine platform from the 1980s which had been under the gentleman's agreement to begin with, especially since back then 350 horses was impressive. The Viper GTS and corvette would make "ooh-ahh"s with 400-500hp btw. The average supercar was what, in the 300-400bhp? The Mclaren F1 had a nearly 15 year production car landspeed record with 600bhp.
