Sorta only done basic mods so far, starting to get up there tho i guess, im wanting to concentrate on new suspension next, but not to much to choose from over here in NZ, so im hesitant to go for anything.

But anyway here are the mods ive done so far.....

Pivot Speed Meter X

Splitfire Coils

Greddy FMIC and piping kit

K&N Pod Filter

Apexi SAFC2 & Apexi AVC-R (Running boost levels of 6psi, 10psi and 14psi)

RPS 3" Stainless mandrel bend exhasut system, full from turbo back, etc.

HKS Cam Gear (Exhaust Side only as engine is NEO and wanted to retain VVT)

When I had the cam gear done I had new waterpump fitted also replaced the tensioners, idlers, pulleys and got a new gates racing belt too (pity no clear cam cover for RB25DET).

did a few other basic things too like got some blue hi temp gates radiator hoses, and replaced all my air lines with blue silicone hoses, because of FMIC i needed a new trans cooler too (needed thinner - factory was too thick), so got one of them as well.

Think thats about it.... :( thanks for asking.

Well here's the dyno chart for my s2.

post-23960-1157156394.jpg

Was very disappointing - its crap basically. Less power than a stock s1.

And also found that there's a fair bit of vibration in the drivetrain - thats gonna be fun to sort out... :)

so yeah the only good bit is the AFR's are fine.

An exhaust + boost controller would give me good power, but would likely throw the AFRs out of whack, requiring some kind of chip to tune it...and its money i dont have, nor will have any time soon.

All i can say is i'm fast losing interest in keeping this stag...just costing way too much...

Was this at the same place that suggested the GT30 turbo? I'd be asking them if they still think it was a good idea and if they can explain why you have less power now than stock (although I am sure you can't prove there was more power before)

That really sucks mate, it's probably still a good car so hang in there and drive it for a while, don't give up too easy. I guess if you want a huge power figure the Stagea might not be the car to achieve that in (not cheaply)... If you choose to move on I hope you make an informed decision and really find what you are looking for in a car.

nah that was adelaide turbo services who suggested the gt30 as opposed to a gcg hiflow. they told me i wouldn't see a huge benefit without bigger exhaust and fuel management. they did a great job so i'm not knocking their work. i doubt there's that much difference between a gt28 gcg hiflow or gt30 anyways so either way i think i would've been in the same boat.

It feels faster with the new turbo when on boost so i'd say the turbo isn't really the issue. i knew i wouldn't be seeing the best from the turbo anway. I'm guessing there are other problems with the car and that it actually only had about ~80awkw when we bought it - due to the stock turbo having issues, especially at higher revs.

Its quite bumpy to drive in, which i always thought was the suspension - but now i'm thinking there may be a bigger issue. I've been getting vibration through the accelerator pedal lately and there was quite bad vibration through the whole car on the dyno, indicating something not right in the drivetrain.

So yeah i dont think its a case of getting less power than before, i think its more that we bought a car from a dealer who pulled the wool over our eyes and covered up all the problems the car had. they knew there were suspension issues before we bought it and only confessed when we got them to fix it under warranty. should've taken the warranty a lot further but too late now.

i dont want to give up on it - but right now i've got the debt from when we bought it, plus the extra debt from the turbo replacement, and no performance to show for it. that should explain how i'm feeling right now... :)

Yes well until you can afford the supporting mods for the turbo I would not guess you'll see any gain in performance.

Also I took my old r33 to a DynoLog dyno and it got 132rwkw and the next weekend took it to a Dynologics and it got 153rwkw....... no change in it, so if you wanted bragging rights, then go around and find a dyno that reads high and run it on that.

My understanding is that a dyno is a tuning tool. You run it then change something, then run it again on the same dyno, rinse and repeat until satisfied. So dont be dissapointed at such a low reading, your afr's look nice and safe.

Now you just have to hunt out that "vibration" and work it out then start saving for exhaust and safc :)

Thanks, thats helpful. Hopefully you're not just trying to make me feel better about it :)

apologies for overreacting a little. But i'd seen a rough 120awkw figure posted on this forum sometime and taken that to be the standard S2 stock power output. and about 100awkw for a stock s1??

a FWD magna got 115fwkw on the same dyno this morning (stock, 147kw at the engine) so i dont think the dyno is to blame at all.

but yes i realise some dynos can give higher readings and that dyno results vary a bit.

AFR's were good. I'm now getting 12.5 - 13L/100km city driving without driving economically at all. thats nice at least.

still a nice car - sorry to all for overreacting a bit and sounding like i wanted to sell it - sometimes you feel like that when things go wrong... :P

Don't give up on the old girl just yet. :) Just think of that dyno figure as a starting point. But I do understand the whole 'money' issue, you keep spending it,but don't feel like your getting anywhere. I think Ska's idea is fantastic, find a dyno that reads higher.......hey when you do let me know!!!! :)

yeah i'll be hanging onto it for a while yet. just real disappointed after spending $3k on a new turbo and not seeing any benefit on the dyno. I expected it to be a little better than stock. It definitely feels faster so thats all I can go by.

Still a nice car. Just need to start saving up for the exhaust and safc (and maybe fmic and boost controller). then i should start to see some nice power figures. my target would only be 150-160awkw. Not after a race car, just a sporty wagon with plenty of grunt. I reckon about $2000 or less would get me there. my gt30 turbo's got loads of potential sitting there - its just a matter of unlocking it.

Tell you what, I'll swap with you. I have all the supporting mods for the GT30 and a stock turbo. I'll give you my turbo and you give me yours until you can really use it and I'll show you it's potential :) WHAT A DEAL!

i was sooooo pissed of on fri. i was all set to go to uas and watch your car on the dyno andy but the dam boss wanted me in the city at 4am and didnt finish till late.by the sounds of it you had a good day

got my stagea dyno'ed today with the power fc installed and sorted out...

...check out the dyno video (click on the picture to play it)

Happy as Larry :laugh: :laugh: :laugh:

Damn nice ! 200rwkw ! good work, thats what- 170awkw? nice, only a cpl kw behind ya ! :laugh:

Pixl8r, mate, I was behind you all day on the cruise - your car booted damn well and Im not just saying that. I was watching......... was very interested in staying behind a S2 thru the hills and enjoying the eyecandy. It looked to me like a 120awkw car. And heading back into the city, Nth Adelaide your Stag pulled off nicely from the lights. :laugh: It NEEDS a full exhaust system. With a little clean cool air your stag would have an easy 140awkw - she's just reavily restricted at the moment. IMO. She's a nice car.

exactly, it can be done. hell, my catback system is a 3inch modified R33 exhaust ! extended behind the muffler by around 10inches.

good luck with the project, watch her evolve over the next few years of ownership. ;)

thanks for that tangles! :laugh:

I definitely think my dyno readout was a bit sus. Will give GWW a call sometime this week and ask them if they can give me any feedback as to why its so low.

Other than that apparently non-shootout-mode dynos aren't that reliable when it comes to power figures - more just useful for tuning purposes. And seeing the results of the magnas that were there on the day - the power figures looked a bit all over the place. You had cars with 163kw at the engine only getting 5 fwkw better than some with 147kw at the engine (all magnas) and it just really didn't add up on the whole. :laugh:

dont wanna blame GWW for anything tho - they do a great job with stags/skylines - but I do think there must have been factors not in my favour on the day. We had the stagea in 4wd mode (button on the dash) but i dont know if that changed anything since at higher revs it reverts back to normal atessa operation anyway as far as i know. I just wonder if the dyno was reading kw at the FRONT wheels only (being a magna dyno day) because the torque split isn't 50-50 in a stag - not sure how the dyno would accurately calculate awkw if the torque split isn't 50-50. Can anyone shed some light on this?

But its a simple calculation - my stag is pretty stock, but with a GT30 turbo, running more boost (8psi) and therefore i assume its flowing more air than stock, but approx 20awkw less than a stock S2 stagea. That doesn't add up.

Also it can keep up with a magna with 115fwkw and weighing 250kg less (actually my top end on boost should blow it away but thats beside the point). If I really did have only 100awkw i'd have been way behind...

that powerfc and fuel pump seems to make a lot of difference, how come you have an Autech bumber? custon fitted yourself or factory? weird to see it on a 25 :)

the front bar came with the car when i imported it from japan.

what boost were you running EGA?

its shown on the second graph (10-12 psi)

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
