Another 60KW is a great improvement. What mods do you have apart from the highflow filter Dave?

lol too many for the measly small power figures... but the usual:

- gcg rebuilt (hiflow) original turbo (neo)

- split front & dump pipe with enlarged front tube to match enlarged exhaust outlet on turbo

- 5-inch body hi-flow cat

- 3-inch straight-through/mandrel catback

- nistune chipped ecu

- jaycar/silicon chip independent boost controller

- heavy duty high stall torque convertor for the auto, 'stage 1' shift kit from mv's w/aluminium servo upgrade

that's pretty much it... yeah way too many for this power I know... but I am still running the standard neo SMIC and it looks completely stock, even have twin tailpipes. I hope that I can get to the sunny side of 200wkw with a FMIC of some sort... boost is 'limited' to about 15psi at the moment. I was running up to about 18 before the boost controller but tuner said SMIC would be a bit risky like that. I love the torque it has now though... just cruises up hills at just under 3,000 revs and 2nd gear pulls almost as hard as first used to... you can really feel the 1st-2nd change...

but before someone says, yes I know I could've made this power and more on the standard turbo... but mine had the whine, bad. And it is to my mind almost as much to buy a decent low-drop front-mount intercooler to improve the standard turbo's breathing as it was for my ~$1,500 ish investment in getting the turbo rebuilt (ok so some of you guys have found intercooler bargains).

I do miss the response of the ceramic turbo though. It did spool very well. But the high-stall convertor and IEBC really helps that, and stall launches are awesome now (even better than with the stock turbo).

Just gotta get rid of my damn misfire (spark breakdown) which is happening now!!!!!

hay guys, got the car dynod today, only had the car for about 7 months now and haven't gone any performance mods as there were alot done already. heres the list

Series 2 2000 Stagea RS4

HKS GTR-S turbo kit

hpi intercooler kit

Full stainless 3" exhaust - trust catback

apexi air filter

spitfire coilpacks

malpassi fpr

bosch 040 fuel pump

Haltech interceptor with Boost control

its running pretty rich atm but the guy down at signature performance here in ipswich said afew hours on the dyno and she would be sweet.

so in acouple weeks i'll get it down there and try again.

Thanks

Curt

Looks like you have lot of the right gear there. Is that 190kw 2wd or awkw? I don't know what that turbo is rated at but I would guess that it is capabable of a lot more. maybe you could do with a better boost controller to give you a steady 16psi. Do you know how close your stock injectors are to max duty ? The afrs are very rich. With a better tune and more boost you will easily be able to do better than 200awkw.

With bigger injectors, a Z32 afm and a really good tune you should be able to hit 230 -240awkw.

no idea about the injector duty, but yeah you would think if the afr's are that bad it should be able to push alittle further.

i am looking at installing gtr injectors ( cos i have some ) and i have a z32 afm on its way. but i have also heard that the z32 afm doesn't like the haltech interceptor so i don't know what to do.

Don't know how much rewiring was required to fit the Haltech but for $400-ish you could get a Nistune installed in your stock ECU. That's *if* you have access to a workshop who can tune with the Nistune. Pretty sure it can handle Z32 AFM (well I will find out soon 'cause I will be getting a Z32 AFM sooner or later).

the haltech was already on the car when i got it. the boards are about $300 i think and i have a service tech that can install that for me. i can't see why you couldn't run the nistune and the haltech together to be able to run the z32??

diagnose the issue>?

What boost and rpm limit

Seems to be still producing easy power to redline.

That turbo is good for another easy 50rwkw's. I think it is only just coming on song.

Can they bring boost on earlier at all?

Auto box will be limiting you.

I will have a graph in 3 weeks time with the same Gt3076 but with the larger .82 rear housing to compare

got a graph with boost on it instead of torque?

yep, will pick one up later today - just asked for one.

boost is ~17psi and rpm is cut at 6500rpm

easy power to redline for sure, but the cut that comes in isnt from the stock ecu; its fic related or a component

yeah I want the cams played with next dyno session to bring it in a little more, but with more time trying the fic-8 exe program we'll get there.

and hope to fix that rev-cutout issue so it gets back to 7300

so, to fit next session is heater core, 3 din guages, and get that rpm rev limit sorted, as 6500 is a bit poxy - its set for 7300 so there is an issue there

map sensor driven and tuned now, excellent to drive

Impressive Tangles. Is your bottom end stock?? lol. Just wondered 'cause you were spinning it past 7,000 revs... does it mind that?

cheers matey. yeh everything bar bottom end is modd'd...

but its not like I rev up there all the time. engine is healthy currently.

found after a spin last night that different profec b settings resulted in different rpm cuts

10% gain 1bar boost revcut at 6500 rpm whereas 10% gain 1.15bar boost saw 6800rpm gear changes and no revcut

weird

monday; trackday. will try to sort out during the day.

i think mine is still pulling hard when it up changes too, at some stage ill get it dyno tuned and i guess ill see if this is the case.

does this seem ok for a pretty stock rs4s?

just has a pod and dump back exhaust (stock dump)

runs 8-10 psi on the boost gauge (aftermarket one)

what would be the first step on my way to ~200awkw?

Yep that's pretty normal. Next get a front pipe with split dump. The $64,000 question is do you have a S1 or a S2? If you have a S2 then after the full exhaust get Nistune fitted to your ecu or if a S1 then something like a chipped R32 or other ecu. Then with a good tune you'll be much closer to 200awkw.

If a S1 then get an S2 (R34) smic - forget the front mount til you have a better turbo.

series 2 factory manual

might take the i/c off and give it a clean, prob has a bit of gunk in it after 10 years

and to finish it off you guys reckon a bell mouth style dump is the go too? cos i though the split style were supposed to be better :S

there is what is supposed to be and what happens on the dyno.

my experience was bellmouth = a whisker more power (back to back testing against a "quality name brand split dump)

either will do a better job than the standard one so you can't lose whichever way you go.

S2 rs auto

Pod filter

HDI front mount

profec b ebc

JJR split dump/front

3" stainless with high flow metal cat and cannon

Nistune chip and tune - EFI performance

I think that's it.....

Ideally I'm after 220-230rwkw

So it's looking like I will need a turbo and some injectors to get there.

hmmm, will look into a nisstune - anyone know the rough cost +install?

also been looking at bikirom too, anyone know anybody running one? they have a daughterboard setup for er34's (same neo motor)

    • Hey was wondering if you ended up installing the R33 GTR speed sensor - I found one too and wanted to confirm it's a direct swap into the R34 6 speed?
    • After 23 years of owning a Skyline, finally had the latch go.  Followed this guide,  works like a dream again. Great Guide 👍
    • Hi all,   I’ve got the biggest lot of problems with my R33 GTS-T   It was a freshly rebuilt 25th anniversary RB25DET (plastic cas, neo cams) probably 6 years ago now   The engine was running so well but I fkd up badly and trusted someone I’d known for 10 years that was well known around Plazmaman for his welding and fab work. I added a lovely photo of some of his previous work. Not sure why my car was worked on by whoever did this shit     I’m normally someone who would never open myself up to something like this, I still can’t believe I did it. Trusting him literally fkd it all up for me. Everything has been a struggle, like it’s almost been 6 years that’s how much I’ve just on and off been trying to work it all out.    All I wanted was a car that danced down low, like full boost from around 3~3500rpm to redline, don’t really care what power it puts down (if it ever does) but I just wanted it to be quick to get on it.    He recommended the turbo to get, I picked Hypergear but he told me to get the front 4” with a T4 and 0.68 rear housing.    I was expecting all these beautiful welds, tidy fab work and paid for it to be ready to go to a tuner when I got it back.    I got a car back that was an absolute mess, I actually couldn’t believe it was my car anymore. I don’t think you could even call what he did welds, they’re disgusting.    So I stripped everything he touched off it and with every bolt I loosened it just got worse and worse.    I covered it and literally built and finished another car in the meantime but now it’s getting to the point where I really want my Skyline back.   Its a struggle because I paid him to do all this shit because I didn’t know how to and now I’ve had to try and figure it all out omg    Please excuse the bird shit horrible welds, I’ve got my show pony car and am so beyond dealing with this car I don’t even really care at this point.    If someone told me about what he did to my car I wouldn’t have believed them but it happened to me. It was unbelievable. He went missing, my car went missing, it came back missing parts, the straight af chassis rails bore the scars of being dragged up a trailer backwards, even the sandwich plate was bent. Everything was leaking and open to whatever fell into it, rounded off/ missing bolts, power steering oil and coolant everywhere, no gaskets, parts stolen off it, even managed to damage the sump pan.   Promised me he’d finish the car, knew what it meant to me, I paid him thousands and thousands just for him to trash it. He told me he was fully licensed and insured, come to find out he’d cancelled his ABN, so obviously no insurance. I had laid up insurance on the car and would’ve been covered but I was scared they would’ve written it off or because the business was no longer trading I’d still be liable.    He was supposed to:  New fully custom mild steam pipe exhaust manifold with turbo location moved from factory position to high forward mount. (I don’t know if it is a mild steam pipe, I’ve got a funny feeling the waste gate isn’t in a very good position and I don’t think the outlets off each cylinder are equal) 4” custom stainless steel dump with external gate (he re-plumbed it) Cut and shut OEM intake manifold with throttle reposition (I ended up doing the throttle reposition) Box in pod filter (left out) New 100cel catalytic converter (pretty sure it’s there but unsure if it’s 100cel) Front mount intercooler piping fabricated to suit (all smashed up and rusty holes where he was supposed to make it look standard where fmic piping passes through. I don’t even think my front bar is going to fit 🙄) Custom 5” intake pipe from pod to turbo (didn’t come with it so had to do something to make it work with the Z32 afm)   Engine: Full cylinder head service & machining  Brand new valves Precision upgraded spring kit Engine block honed New bearings  New piston rings  New ARP conrod bolt kit New ARP head studs Cometic head gasket VRS kit   ATR43SS2 ball bearing turbo 0.68 rear housing  Turbosmart 45mm external wastegate (got delivered to the fab bloke, I’ve got no idea what spring is in it, I’m assuming the one that came pre installed) Walbro 260 fuel pump  Nismo 740cc injectors (tested to 880) Spitfire coil packs GCG FMIC RB25DET manual 5 speed 4:11 rear diff   I’ve got an Apexi Power FC in it atm, I was hoping to just get it to operating temp to make sure everything was okay before towing to a tuner but it’s over-fuelling too much. I don’t think that’s going to happen so i think I’m going to get either a Link G4 or Haltech for it. What do you guys recommend? I can’t work out the power FC so just gonna give up on that one     It’s got an exhaust leak coming from somewhere I can’t see 🙄    The fuel pressure was steady but now it like drops from 40 to 20psi randomly (noticed this yesterday)    I’ll attach pics of the shit he put on my car and the engine bay now as it sits    I really just need some help, I need a tuner in Sydney I can trust, I’d like to be with the car while it’s being tuned if possible, I know it looks terrible but unfortunately I’ve just got to put up with it for now and fix the cosmetic stuff later   Do you guys think the manifolds are going to be okay? Or do I throw the exhaust manifold and try again?   I don’t even think these combinations are going to work tbh   I know everything I fitted was rated to be able to take at least 400kW but most rated higher    If you’ve gotten this far I really really appreciate it 🙏 I don’t mind if you trash me or the car, I made a rookie error and f**k I’ve paid for it. As you’ll see 🙄  
    • From everything I’ve heard you’ll be waiting a long time for  the parts to arrive 
    • Have you looked at the workshop manual?
