Depends what power you want really, I've had two RB26 set ups essentially and the one I have in my GTR now is the best I've had (the stock unopened motor is holding it back alot however) I have had 3 single turbo set ups on my GTR to date.

I'm currently running a Precision Billet series PT6262 turbo charger, un real response full 1.6 bar by 4200rpm on 98RON however with a built motor my peak power would be a lot better. Previous set ups have included a Garrett GT3582R and a Turbonetics T66 (plain bearing 0.90 roughly housing) I've never liked the poswer delivery of twins however they may have their advantages in the 3-360kw range. However I have no complaints since changing to a single high mount plus the maintenance is a hell of a lot easier :)

Awesome thanks mate :) is it a lot of stuffing around to go to single? Sounds like you have some awesome setups!!

What do you have to change to go single? Do you still get aircon ect. I was reading that some people change a heap of stuff I'm not gonna go to big just something that looks nice and is resposive

if your arfter a bit more kick, why not just get some -5's? you have good supporting modes in place and they will just bolt up to your current setup. would be a cheaper option then going single.

single would require new intake piping, exhaust manifold, dumps and front pipe etc.

If your keen on the single route, i see alot of people getting good results with a t04z

Well it made 320kw on around 20psi which I'm

Not happy with however it may have something to do with the only mildly decent tuner up this way tuned it to around 10.8:1 afr's lol so it would make 350 or so leaned up a bit... However I was also after a bit of life from the stock motor to so I'm not complaining.

Going to a single was the best thing I ever did for my GTR, in terms of changing things that's par for te course however it's definitely worth it.

My GTR is currently getting parted out.... So my turbo set up is for sale complete with hot side piping, dump and front pipe to suit 32/33 GTR and intake pipe lol

Sedat i have been very impressed with precision turbo's. I hve just finished a r34 neo with 5558(precision) it made 367kw on 22psi ethanol and full boost at 3900,

I have just fitted a 6262 twin scroll onto my personal GTR which i was planning to tune this week but found a water leak under the plenum so i pulled that iff tonight.

My aim is 400kw with full boost at 4200.

U should go a 65 series or so for 450+kw

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By nouveau_poor · Posted

      I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly

      R34 Skyline Sunroof Won't Tilt/Vent

      I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.

      It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣

      R34 Skyline Sunroof Won't Tilt/Vent

      By ShezzDogs · Posted

      Hi guys, just after some guidance with an R34 sunroof that has stopped working correctly. It still opens and closes perfectly fine, but it no longer tilts/vents up or down. As a result, the rear of the glass now sags a bit as it drops down slightly in order to retract into the roof, but now it can't pop upwards into a flush position. I’ve probed the pins on the back of the switch connector with a multimeter and it seems like both switches (for open/close and tilt/vent) still work correctly. Any ideas on what it could be, or where I should even start in terms of diagnosing? I'm sure someone's had this issue before but I haven't been able to find anything online relating to this specific issue, most of the issues are with the seals leaking or the motor failing entirely. Thanks in advance!
