Just found out something curious

Officially, stageas have less power at the flywheel stock than R33's.

Skyline http://english.auto.vl.ru/catalog/nissan/s...e/1996_1/21671/

vs

Stagea http://english.auto.vl.ru/catalog/nissan/s...a/1997_8/21850/

Why the hell did they detune the stagea when its 300kg heavier!

Nissan decided that the S1 auto gearbox needed some protection from the heavier weight

The manual (S2) Stageas have the same power as (R34GTT) Skylines

But what about S2 autos and R34GTT autos?

:D cheers :D

Somewhere in Skylines there is a comparison of a Stagea, (S1 or S2 I dont know) and two or three other FI cars. The Stagea did better than some. Perhaps someone (SK) knows what thread.

According to this: http://english.auto.vl.ru/catalog/nissan/s...a/2000_6/21829/

The S2 Auto and Manual both have 280ps, which doesn't surprise me too much.

I was under the impression Stagea rb25det runs a little less boost that R33 versions. Like 6-7psi Stagea, 8psi Skyline. Although that would imply different ECU maps, otherwise, based on Stagea AF's, the Skyline would be too rich.

It's just a different calibration to protect the auto. The autos break! Heaps of cars are detuned for the auto variants. The Stagea is detuned a bit more than the skyline auto because it id heavier and AWD.

yea true the detune it cos their auto gearbox cant take it. This is also true for an Rx8 an uto the rev limit is at 7k where the manuak goes to 9.5k rpm.

well, i really dont think 10kw difference will kill an auto box....

but hey, we've all worked out an extra 60-70kw can :cheers:

More likely the 20 nm of extra torque

Regarding boost, our Stagea came with 4 psi / 6psi (high / low)

The R33GTST came to us with 5.5 psi / 7.5 psi (high / low)

So my guess is the extra 1.5 psi of boost accounts for the torque difference.

Auto ECU’s and manual ECUs in R33GTST’s are definitely different.

When I swap the turbo on the Stagea, I will check the wastegate actuator spring pressure. If my guess is correct, the Stagea wastegate spring should be ~1.5 psi lower than the R33GTST spring.

:ban: cheers ;)

I always thought this was just down to slightly different configuration between the two cars.

To use another example, look at where the VQ35DE engine is used, its in like 5 different nissan cars (probably more), including the 350Z, stagea M35, maxima, skyline v35, patrol?, and there are sure to be others I've missed.

In all of these cars the power figures differ - either in kw or torque or both.

I figured it was just that the setup is configured differently depending on the purpose or the target market of the car.

Sounds like the same theory diesel engine manufacturers have.

Most common rail deisels will produce a difference of up to 200 HP from the same motor simply by programming the ECU. You simply tell them what you want the motor to do and they'll program it for you.

    • Probably speedometer itself if the odometer is ticking. If the needle is stuck from a bit of grease or something that can cause it to stay at 0. Or a cracked solder joint in the speedometer can do it too.
    • Thanks Fella’s   to take this off topic and to elaborate a bit more. I have an rb25/30 going into a r32 GTST.. expected to make around 600-700hp. Would you?   A) R34 GTT box   B) CD00#?  I’ve seen a few posts about the CD swap and sounds fairly involved with making it fit etc but if it’s worth the work then I’ll go that way
    • Lower at the hubs. Funny I forgot to mention that part. Do this pull here I turned the camera off too soon but the graph shows a drop at the top and that was because the pipe from the turbo blew off. The tuner said we could’ve made possibly another 15 whp. He also added if I switched to ethanol we could up the boost some more as well. I was comfortable capping it at the most of 20 pounds. Turns out the turbo pipe just needed a new worm clamp. Got home replaced that then did a third gear pull from 3k to 7200 rpm and the power was great to the top. I just got an ecu mounting bracket from IEE that I need to try and get everything to fit well. It’s a PITA to get the harness and ecu fit properly behind that kick plate 
    • He means "as opposed to mechanical cable drive". Older cars (R32 for ex.) had cable drive. Later cars with essentially the same gearbox, ie R34 GT (NA RB25) used essentially the same box as the R32 GTSt, but instead of a cable drive, had an electronic speed sender plugged into the same hole in the box, running from the same little gear that would have run the cable. Some of the shittier later cars use a speed sender on the nose of the diff, or the ABS sensors.
    • Lower than engine, or lower than it should at the hubs? Either way, that is a nice power figure and I'm not surprised you say it rips now. What stopped you from turning it up any more? Injectors? Or did it just stop responding to boost?
