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.

      Mistakes were made, my R34 Story

      (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.

      Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things

      My new to me M35 Stagea wagon

      Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
