Wacky Dee

Cheers mate, I'll try and get a dyno run at UAS asap and will report on the results.

Finally someone with proof to back up what I was saying all along .. thanks mate! Got a couple of q's for ya if you don't mind .. did you have your ecu remapped by any chance and if so by who? Any chance you did a dyno run before upping the boost to 11 ? Where'd you go for your dyno run? Cheers Edit: yep it's a manual.

Hm ok I just quickly searched for dyno results and found this r34 gtt auto (8psi boost) and he made almost 20rwkw more than my car and with the same mods .. just a different dyno? What's this about remapping stock ecu .. i thought you needed a pfc to remap/tune the ecu?? please do tell me more! I might take it to CRD for another dyno run as I heard they use a different brand ..just to see if I get similar results

first dyno run and only 145rwkw If anyone's even remotely interested .. I have a lengthy write up at http://www.skylinesaustralia.com/forums/Di...ul-t219960.html

See the thing is i wasn't expecting a beast but everything I've read before on SAU points to the 160-170rwkw figure for a stocker and additional 10-15kw with a turbo back. Are all those people just full of shit ? If so, why do so many make that much with the same mods and have it in their signatures?? Different dyno ?? Oh and another thing .. the tuner quickly looked up their database of previous customers and found another STOCK r34 GTT that put out 184rwkw. This was when he said 'hmm.. you're right' and called the mechanic to take a look. I'm not trying to achieve the impossible but to me it seems 25% less power than a lot of other people with the same setup points to something not being quite right. Couple that together with the fact that I am pretty sure the car had a lot more 'oomph' before the timing belt change ..

Here's the dyno graph...

The mechanic was listening for detonations and he said it wasn't making any ... actually both him and the tuner were both surprised that there was no detonations/pinging at the 17-18deg setting, they said most skylines would do it at those settings. In the end he reset it back to 15. I am getting an O2 sensor installed hopefully sometime this week and they'll reset the ecu, I'll see how I go after that. Oh and I've only been filling up bp ultimate since I got the car (3 or 4 tanks now) Cheers

yep, turbo back exhaust (and 18" rims) - other than that it's a stock car. The dump/front pipe is JJR, the cat is a highflow xforce cat (JJ guy reckoned he uses the same one in his GTR that makes 300rwkw) and the catback is an HKS Silent.

Please bear with me as I tell the whole story from the beginning .. it's not very long I promise! I bought a stock standard R34 GTT a few weeks back with 62,000 Kms on the clock. The car seemed in very good nick, albeit no performance mods. So the next day (so to speak) I got a turbo back exhaust from justjap (front/dump pipe, highflow cat and 3" catback) and noticed a smoother drive and the boost was coming on earlier too (around 2500 rpm instead of 3000) and I was a VERY happy chap... until... I took the car for a timing belt change since most of the drive/psteering belts were very worn and/or cracked (and who's to know the car's odometer hasn't been messed around with so it may have already done 100k). One the timing belt was changed, I came to pick up the car and on my way back home I immediately noticed that the car didn't feel as if it had as much 'oomph' when the boost kicks in as it did before .. (to this day I'm not sure if this is just all my imagination). So I asked around and someone suggested that a timing belt off by one tooth could explain the perceived loss of power. So I thought I might as well take it for a dyno power run and see what I get at the rear wheels. I took it to Bel's Garage (very pleasant and helpful peeps) and after 2 runs we noticed the car was doing only 143rwkw. The tuner thought that's probably about right and I said it sounds a bit too low as I was told that a stocker should get 150-160rwk and a full turbo back exhaust should probably add another 15kw as well so I was hoping to see something like 175-180rwkw but instead what we got was 143. So he spoke to his mechanic who came over with a timing light and reckon the timing was right but then he noticed that the ingition timing wasn't reset to the default 15deg, instead it was set to 5deg only. He said whoever changed the timing belt, rushed the job as the ignition timing should be at 15 atleast so he cranked it up to 17. Both the mechanci and the tuner at this point seemed confident that this explains the low power output and that we can expect a lot more on the next run ... So they do another dyno run and lose boost at 6psi and everyone's scratching their heads ... the mechanic says he reckons the actuator must have got stuck when open. Turns out he was right .. the actuator was stuck open apparently because the aftermarket dump pipe from justjap wasn't fitted properly .. So he fixes the actuator and we do another dyno run. And this time we don't lose boost and the car does 145rwkw (2kw increase only since fixing the ingition timing!!!) and everyone's scratching their heads again "should be a LOT more than 2kw increase" they reckon. At this point it's already getting late so they can't do any further diagnostics and put it all back together. The mechanic tells me he has no idea why it's making 145rwkw only, even after fixing the ingition timing. So here I am now .. totally deflated and disappointed. I guess I probably should have gone in with lower expectations than 180rwkw, but 145rwkw with after-market turbo back exhaust just doesn't seem right. What do you guys reckon? What else could it be ? Could it be the coilpacks? Maybe one of them is dead ? Anything else that could explain the lacklustre performance ? I will post the dyno graph (final one) as soon as I figure out how to work this damn scanner.. Cheers

hope you don't mind the hijack mate .. can anyone just explain the difference between the powerfc and safc ? are there any other aftermarket programmable ecu's for and r34 gtt?

yeah i dont have any of those silver bits (speedo, shifter and dash, windows buttons etc) so it must be a series 1. Must say I like the s2 update ... shouldn't be too hard to make it look like an s2 anyway though I think there's a thread here somewhere on how to paint the plastic bits into any colour you like

sorry, I need the spare (and no it's not like the normal wheel, it's narrower)

Neither did I but apparently there are ... was gonna buy some dash leds but the seller says they're no good for the s2 r34 so I'm trying to find out which one I've got. googlign 'r34 series 2' brings up a lot of results too eg. Redline Stock ListR34 GTT Series 2 Coupe 2.5lt NEO turbo 206kw Straight 6. Stock 5719 NEW STOCK Year 1999 Price $19990 Kilometers 84198 (Grade 4 Auction Report, ...

if someone could answer that for me or tell me how to determine it myself, cheers.

Here are a couple of pics of the rims and rubber... enjoy.

I was under the impression the timing belt is a bitch to get access to .. ? Can anyone show me some pics as to what I should be looking at precisely as I'm not so mechanically minded (although my dad might be, but I don't trust him with a skyline ..his forte were gemeni's ;D) Could a dyno power run do any damage if the timing is one tooth out? I wanna be sure there's something wrong before I actually take it back to the place that changed the timing belt so I don't look like a complete tool. In my mind, there's definately less power since the timing belt was changed .. the turbo doesn't seem to spool up as early or as much as it used to and there's no sudden oomph when it does. It feels like I'm just running on 6 cylinders. Having said that, when the car is idle it's not rough which I've read somewhere is a definate sign of wrong timing ... so it could all be in my head hey?

Thanks mate, i'll be in touch soon to order the shocks, caster kit and subframe alignment kit. Cheers

you got offered $20k for plates and turned it down??? that is absolutely insane.

hmm shit that doesn't sound good. Would you recommend against dynoing the car if it's "one tooth out" .. could the dyno do more damage? Any way of checking if it's one tooth out without actually taking the whole engine apart again??

Item: HKS Turbo timer Age: No idea, came with car Condition: working Price: no idea, make an offer To Fit: came with my R34 GTT Location: camperdown nsw Contact: pm me or email [email protected] Comments: The turbo timer came with my R34 GTT and was taken off because my new alarm system has a built in turbo timer. I have no idea what the model number is but the brand is HKS. No idea how much they're worth, so make an offer. Cheers.

Item: Stock R34 GTT rims with Dunlop Direzza DZ101 225/45/R17 rubber Age: Rims are stock factory wheels, no gutter rash that I could see. Condition: Rims are in very good condition, the rubber is also very good (atleast 50% I reckon) Price: $600 ono To Fit: R34 GTT (the offset is +38 iirc) and other cars with similar offset. Location: Camperdown NSW (near Newtown) Contact: pm me or email me at [email protected] Comments: The wheels are obviously the stock factory GTT wheels so about 10 years old. I got them with the car and I am pretty sure there was no gutter rash on them (I will double check this tommorow). The rubber on them is very good quality performance tyre from Dunlop and from memory I believe the tyres are still in average condition ie. 50% of thread at least (hence the asking price) so could potentially last another 1-2 years. These tyres cost approx. $250 a piece. I will take some pics tommorow as the wheels are at my parents place in their garage. Obviously due to weight, pickup only available (or if you want to organize delivery to some other city, feel free to do so but expect $70-100 freight costs)

Item: Dopod 838 Pro Age: Less than 1 year Condition: Very Good Price: $250 ono. Location: Camperdown NSW (near Newtown) Contact: pm me or email me at [email protected] Comments: I bought this smartphone approx. a year ago, paid $800. The phone broke down shortly after (the LCD module died) was was repaired under warranty. Because I needed a phone during the repair I bought a new phone and when I got the dopod back, hadn't used it all. The repair shop fixed it properly and the phone is fully functional. They even updated the software to Windows Mobile 6. For full specs please see http://www.dopodasia.com/Dopod/Singapore/E...838Pro/spec.htm Can ship anywhere in Australia at buyer's expense or pickup also available. Please excuse the 2nd pic below - the screen does NOT look washed out like that in real life, it's just a crappy pic. The screen/PQ is very sharp irl.

Item: 2 leather jackets, very large size (5XL) Age: approx. 2 years Condition: as new Price: $150 each or $250 for both Location: Camperdown NSW (near newtown) Contact: pm me or email me at [email protected] Comments: I bought these approx. 2 years ago and wore them maybe 5-6 times. At the time I bought them I was overweight plus I am very tall (approx. 2m/6'6") so these are very large size jackets - I believe it says 5XL on the tag. They are very nice jackets but will suit only a tall person of big stature. I can measure the size if necessary if anyone is seriously interested. I paid $700 for these 2 on special (store was closing down) and they cost $450 or so each normally. I'd like $150 for each or $250 for both. One of the jackets is 'Nahka Albert' from Finland and the other is Arepelle Australia (italian leather). (please excuse the bad shots .. the jackets aren't that shiny, that's just the camera flash)

Item: Xbox Console Halo Editio (green see through plastic) + 2 matching controllers and 13 top games Age: approx. 2 years Condition: Great, less than 100 hours use. Price: $250 ono Location: Camperdown NSW (near Newtown) Contact: pm me or email me at [email protected] Comments: The condition of the console is as new as I rarely played it and it's been collecting dust for more than a year. It includes 2 matching controllers and 13 of the best games for the Xbox incl. GTA San Andreas, Ninja Gaiden, Burnout 3 Takedown, Rallisport Challenge 2, V8 Supercars 2, Splinter Cell, Mortal Combat Deception, Soul Calibre and a few more I am ONLY selling the whole package together. NO individual games, sorry. I can post it anywhere in Australia at buyer's expense or you can pick up from my place directly. Any questions, ask in here please (not pm) so that I don't have to answer the same questions over and over. Once again, I will NOT separate the games .. only sold as a package. Asking for $250 ono. (last 2 games I bought, GTA and Ninja G. cost me that much almost and I haven't even played those games due to no time)

Gary, I'm very close to placing an order (just trying to get the money together) If you don't mind answering a couple of additional Qs I'd much appreciate it. I've pretty much decided to just change the shocks and stick with the stock springs ie. will lower the car 20mm (or is it 24mm?) only ie. 360 front and 350 rear. From what I understand, I won't need any camber kits (well maybe for rear, but unlikely) Anyway to the question ... my mechanic who did a quick visual inspection said that the 'crack marks were found to both front pan rod bushes'. 1) What does this mean and what do I need to fix this? The caster kit? Does the caster kit include these pan rod bushes ? 2) Oh and while I'm at it .. I've seen you mention in the group buy thread that one can lower the car 24mm using stock springs but above you recommended 20mm. I'd prefer 24mm if the stock springs can take that .. what are your thoughts? 3) regarding the subframe alignment kit .. in the group buy thread one of your customers mentioned he had it installed but notices some extra humming noise coming from this kit. He says it's quite noticable but not too obtrusive. What's that all about? And thanks again for all your detailed and helpful responses thusfar.
