u do realise that a NA engine has more torque due to the fact it dosent have forced induction to get everything going?

That i do and would work in theory......but i would still like to compare your torque figures with mine.....regardless anything else....

Despite being able to immediately impound the car under anti-hoon laws, the driver was allowed to continue on his way. He has been ordered to take his car to a police station tomorrow, where it will be impounded.

"The speed he was travelling at ridiculous.''

Yet they let him continue driving to his appointment ... even when he showed no care for the 160kph+ speeds he was doing? :pirate: What if he'd killed someone after the cops let him go???

in the report the old guy even confessed to driving even faster before......he said lucky you didnt catch me before....i was going faster....

I mean seriously WTF is wrong with the police....i bet you if it was a 18 year old kid behind the wheel then he would be behind bars and car either impounded or crushed......talk about the cops always having double standards.....

Mate, I've seen 50+ year olds driving hyundais hooning thru traffic and they get away with it day in and day out.

Altho I did see justice last night at Regency Park. P-plater with mates in his "taxi" Falcon edging me to race him at the Regency Rd lights heading north on South Road. I gave it a quick squirt right up to 70kph (speed limit) ... 10 seconds later they screamed past me at about 100kph. The traffic cop (whom I noted was there earlier when I drove past) on his bike was hiding on the other side of the road, pulled out, gave chase and they got nicked :pirate: Yeah, I set them up a bit, but they didn't need any encouragement anyway. :P

how was everyones day?

Same as yesterday really, so-so. Woke up at 11, had breakfast, moved a garden shed, started surfing the forums, watched the chasers war on everything, and played some cod5 coop with a mate. Tomorrow i am back at work, i find that i am rather bored unless i am going something...such as working.

How about you?

only na nissan engines worth driving imo are v's over 3.5 litres.

wut?

yes solid lifters, lower emissions levels , and if its a series 2 it has higher torque cams in it. the output goes up to 206kw as well

  • RB25DET - twin-cam turbo (T28 Turbo) (245 to 250 hp and 319 N·m)
  • NEO RB25DET - twin-cam turbo (206 kW (280 PS) @ 6400 rpm, 362 N·m (37.0 kgf·m) @ 3200 rpm

Released in 1998, the R34-series Skyline engines have a big emphasis on reducing emissions.

The existing RB25DET was reengineered to NEO specs, which apparently produce around one-tenth of the CO, HC and NOx emissions levels allowed under Japan’s 10-15 test mode. Further changes include a ball-bearing turbo, slightly larger intercooler, free-flow exhaust and revised ECU (which allows up to 10 psi boost). revised in late 2000 bringing extra torque (probably through a bit of extra mid-range boost).

Not sure where the RB25DET engine torque figure listed above came from, but it's actually quoted by Nissan as 30.0kgm at 4800rpm - just under 295Nm.

If one were to take the RB25DE and RB25DET minus it's turbocharger and compare the torque output, the naturally aspirated RB25DE would indeed make more torque, due to the 10:1 vs. 9:1 compression ratio. Now add the turbocharger back into the equation, where it rightly belongs on the RB25DET, and 230Nm vs. 295Nm tells the story.

Correct, however an N/A 25 will never make more torque than a turbocharged 25. Hence my "what the!?!?!" :)

    • 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
    • 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. 🤣
    • 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!
