A skyline that lags is better than a chick that nags

Ooh which one did you go for? Details? Sounds positive

Sweet, will keep an eye out for you! Be careful around Newcastle itself if your car is modified, the boys in blue had ruined the car scene up here due to the minority that spoilt it for all of us!

I could be wrong, but I'm pretty sure it's the other way round mate.

Who's telling you this? The seller?

-9s are An updated version of the -7s, pretty much the same response as the -7s but flow a fair amount more. -9s on the same set up make more than the -7s etc...

i spoke with DVS Jez, and a few other ppl they will make the same power diff is, the -7s have more top end and the -9s have a bit more down low, but in the end they will both do the same job.

also ill be getting a platnum pro plugin for her.

yea fair enough, i really thought it was the other way round though. -9s being slightly bigger but better in design, therefore only a tiny bit more lag than the -7s but more top end..

i was fairly certain the -7s were the smallest upgrade turbos you could buy, but there is so much confusion around these turbos that i wouldnt be suprised if i had it wrong haha..

Wedge you know abit about this dont you?

The only difference between them that i can find was the exhaust wheel 1 was like 3mm bigger then the other or somehting like that. But i cant wait 3 weeks for -9s anyway so -7s will have to do im over all teh waiting and f**king around, just want it to run so i can enjoy the car.

yea fair enough mate.

just be easy on the clutch when you get it back, its generally the weakest part of the car from stock. and it is advisted when going with bigger turbos to upgrade it etc..

you doing anything else bar turbos and computer?

I'm not 100% sure but i believe the exhaust housing is slightly different design on the -9 too.

-7's = r34 n1 turbos

-9's ARE HKS GTSS turbos

The graphs i looked at when researching turbos showed <150rpm difference between the two (-9's been slightly worse), but the -9's usually had the better top end (10-15kw's), however this is highly dependent on supporting mods and i couldn't find any back to back comparisons (who's going to waste 2.5k to go from 7's to 9's unless the've blown a turbo)

TBH throw 20-24psi through either of them and your going to be making ~330awkw and absolutly exstatic. You can't really be disappointed with that.

all this talk of turbos is making me very keen for the next stage on mine..

seriously going to have to consider E85 i think.. have seen results with a similar planned setup as mine making 370awkw!

will be hard to pass that potential up i think..

Yep - I've been saying for a while i rekon it would be possible to crack 400awkw with E85 with 9's.

Someones 34nur in melburne made 379awkw with 7's (stock n1's) and E85 recently.

Yea I reckon 400 would be too much for those turbos... Could probably get a dyno to read it, but how accurate?...

I'm pretty sure both run out of puff around 22-24psi?...which would restrict huge top end power etc...

Yep, going to do mid pipe on my exhaust since the cat back is 3 and a half inch and so are the dumps but has the stock mid pipe, also needs a new clutch as mine is almost shagged, will do injectors and maybe fuel pump with the ECU, then after i have it all sorted in a year or so i may put a big single on it when i get another car as a daily, and go for massive power since the engine is built for it.

ohh and i hope everyone has taken the restrictor out of the side of the stock air box to, it just pops out 2 clips just use a flat head screwdriver, will double the air into the box, i can now hear my car sucking in that sweet sweet air as i thunder down the roads lol.

      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

      By GoHashiriya · Posted

      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.

      Shoota's R33 GT-R RB30/26

      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!
