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

Cool. Yep the one I bought comes with a Tomei plug.

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

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 !

cheers

    • perhaps i should have mentioned, I plugged the unit in before i handed over to the electronics repair shop to see what damaged had been caused and the unit worked (ac controls, rear demister etc) bar the lights behind the lcd. i would assume that the diode was only to control lighting and didnt harm anything else i got the unit back from the electronics repair shop and all is well (to a point). The lights are back on and ac controls are working. im still paranoid as i beleive the repairer just put in any zener diode he could find and admitted asking chatgpt if its compatible   i do however have another issue... sometimes when i turn the ignition on, the climate control unit now goes through a diagnostics procedure which normally occurs when you disconnect and reconnect but this may be due to the below   to top everything off, and feel free to shoot me as im just about to do it myself anyway, while i was checking the newly repaired board by plugging in the climate control unit bare without the housing, i believe i may have shorted it on the headunit surround. Climate control unit still works but now the keyless entry doesnt work along with the dome light not turning on when you open the door. to add to this tricky situation, when you start the car and remove the key ( i have a turbo timer so car remains on) the keyless entry works. the dome light also works when you switch to the on position. fuses were checked and all ok ive deduced that the short somehow has messed with the smart entry control module as that is what controls the keyless entry and dome light on door opening   you guys wouldnt happen to have any experience with that topic lmao... im only laughing as its all i can do right now my self diagnosed adhd always gets me in a situation as i have no patience and want to get everything done in shortest amount of time as possible often ignoring crucial steps such as disconnecting battery when stuffing around with electronics or even placing a simple rag over the metallic headunit surround when placing a live pcb board on top of it   FML
    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked...

    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily.
