So I’ve got a new turbo on the way from Hypergear and wanted check whether I’ve got my supporting mods covered. The handling and brake upgrades etc have been done.

The car: '99 C34s2 RS4-S Stagea

Current Mods:

  • Greddy Front Mount Intercooler
  • 3" Full stainless steel Fujitsubo exhaust and stainless steel front pipe with 3" Venom 200cpi hi-flow cat
  • Nistune ECU
  • Turbosmart Boost Tee
  • Nismo High-Flow Volume Fuel Pump
  • HKS Panel Filter

The turbo: Hypergear ATR43SS2 inc billet comp wheel, oil line and 14psi actuator with Nissan 6bolt OEM assembly.

Mods to be installed with turbo:

  • Nismo 480cc Injectors
  • Z32 AFM
  • Scotty metal intake pipe

Is there anything else I should be considering? Subscribing to the “do it once, do it right” philosophy here, so would much rather spend a bit more on quality parts now rather than have troubles and/or dissatisfaction down the track.

Would it be worth ditching the Turbosmart Boost Tee in favour of a Greddy Profec B Spec II? Is upgrading to a Splitfire coilpack going to make a difference?

Cheers guys.

The t will be fine my greedy boost controller sits in the car not hooked up just ended up using a t much easier to tune with and if your stock coil packs are holding up they will be fine too but some time down the track they will need replacing , have you got the plug with afm

i basically done everything u done above with same turbo except for the injectors and only have cat back zaust.

Main mods i would have liked to have completed if funds permitted would have been injectors, dump pipe, ebc, shift kit, cams & greddy plenum. Its a good turbo by the way excellent midrange

Internal gate, so a EBC might be worth it... depending how hard you want to lean on it .External gates are a different story.

Ill be interested to see how it goes, was so close to getting the ss2

cheers

Yeah I'm worried about it being too laggy... my understanding is that an EBC can help bring boost on sooner?

R34 GTT Brake conversion...

You might as well do oil and plugs while your at it... especially plugs before a tune.

Gaskets (as above) and vac line.

I'm interested to see how you go with the ss2 on a heavy stag.

Cheers

Justin

PS... an ebc will only bring the boost on sooner if the actuator is 'blowing' open prematurely. it can't make the turbo spool any faster.

R34 GTT Brake conversion...

It has R33 gts-t brakes with slotted rotors atm.

I should probably mention that I'll be getting this all done at a workshop... I'm not game to tackle something this big!

Fuel pump?

See first post - it has a Nismo fuel pump ;)

Ouch work shop sounds expensive

Yeah it won't be cheap, but at least it will all be installed at once and then tuned. Thus my reason for wanting to make sure I haven't overlooked anything!

Just out of curiosity Andrew, what kind of costs have you been quoted for the new Turbo and Injectors, etc? Interested in doing those upgrades as well, I've got the same (almost identical) Mods to you at the moment, so I'm pretty keen to know what I'd be up for.

In relation to the SplitFire coil packs, I'd highly recommend the upgrade, whether your existing packs are good or not, if you've got the cash to spare, get the new packs, you won't regret it. The existing stock coilpacks will most definitely shit themselves at some stage.

The total for the turbo as described above was $1500 delivered. PM Stao from Hypergear for a quote.

The injectors, I'm getting through forum member 'elrodeo666'. Marcus is able to order directly from Nismo in Japan. The total was $725 delivered.

Who's tuning/fitting it all ?, i got the G3 type A, be interesting to see the difference when finished, mines auto though

Your car will be a allrounder after turbo fitment, looks so bloody good , will have the speed to go with it to !

      Sorry, are coilovers ACTUALLY ILLEGAL in NSW? They aren't in Vic, as long as they retain 70% of stock travel and the car is above 100mm off the ground. Does NSW actually have a law making coilovers actually illegal? RWC/Blue Slip/Engineering people not knowing the actual f**king laws boils my blood. Demand them to point to the documentation that states a coilover is illegal. (it may exist in NSW )

      But seriously, can we ask for the results of the "tip a bottle of metho into a nearly empty tank" experiment?

      Hang on. Let me get this straight. The desire is to have coilovers, BC in particular, to be MORE comfortable on Sydney roads than stock suspension? Well, that's obviously not right. BCs have crude damping design at the very best, and typically hard spring rates. BC stands for Billy Cart. And then, the desire is to put in some shitty old worn out stockers, to get it blue slipped and then put the BCs back in? And then.....what? Not worry about getting pulled up by the Plod? Because you seem to have raised a worry about paying for engineering (which actually does solve all your legality problems) and still getting pulled up.... but the only problem there is that if/when that happens you have to show your paperwork at the inspection station. Whereas, if you just swap in borrowed shitty old stockers to get it slipped now, and then you get defected in the future, you have to go find more shitty old stockers then too. You course of action looks like this set of options: Buy brand new stock type dampers, and springs. probably cost a bit more than $1k all up, but will last for the remaining life of the car. Put them in, pass inspection, drive on them forever more. Hell, they could even be really nice Bilsteins and Kings or other lower&stiffer springs if you wanted. Get the car engineered as is. ~$1k. Buy new Shockworks coilvers (or MCA) and also pay for engineering. You're spending a lot more here. But these will be the best things that you could drive around on.

      Might be worthwhile hitting up Facebook's groups, I know most of them contain terrible people and scammers - however you might be able to find someone that's in Sydney with factory suspension you could purchase and/or hire. Just do not send any form of money anywhere, in person cash only.
