    R33 GTST whine, most common gearbox issues?

    in Drivetrain and transmission

    Posted · Edited by Torques

    The car's odo is genuine.

    I bought it at 63K 6 years ago as the first owner.

    I got the Japanese factory logbook, exporter certificates and so forth.

    Though paperwork can be falsified the physical appearance support that.

    Headlights and windscreen are in mint condition , so is the interior (pedals, fabrics, etc)

    Car looks mint from below as well ..

    You don't have that with higher mileage cars.

    I doubt the gearbox was ever touched, but of course you never know.

    added picture

    My gearbox developed a whining sound in all gears. (louder under load)

    I changed the oil and there were metal shavings at the magnet. (more than what you'd expect to see )

    After the oil change the whining noise almost halved and is barley noticeable.

    Shifting is smooth.

    I suspect either the counter shaft or input shaft bearings, is that a common thing with these transmissions?

    Any other usual suspects?

    The box has about 70K on the odo, has never been abused except for the occasional drag run.

    Power wise the engine makes about 290ish rkw

    Cheers

     

    Attached the picture of what the magnet caught.

    Electric boot (trunk) release R33?

    Electric boot (trunk) release R33?

    Is there a drop in part available (from another Nissan maybe) that I could use to open / unlock the boot of my car via my alarm system remote?

    I already retrofitted the passenger side door actuator from a Micra  ... so just wondering if there is a part that fits right in..

     

     

    Thanks you ...

    RB25DET max 'safe' boost for valve springs?

    in Forced Induction Performance

    Posted

    I was trying to get some information since got a new turbo capable of 24PSI@ 6500rpm which is a big step from the 15PSI of the old turbo.

    While being on a roller I found that the power curve went through some strange 'ditches' and I was wondering if that might be due to valve float.

    Valve float was not of any concern to me before simply because my old turbo was running less boost.

    I'll dial in 20PSI and run more timing to get a good baseline, from there I can work it up should I feel the need.

    Thanks for the input!

    I might be a bit picky with how work is done, but to me it looks like a no brainer to make as much space around the wheel as possible ..

     

    And yes, I was thinking doing just that with a Dremel.

    But the whole project had been going back and forth for a long time and I had the workshop appointment the next day.

    So I didn't want to take housing off again and wasn't feeling like masking the wheel with gaffer tape and then possible sliding off with the Dremel (if you know what I mean)

    Machined out turbine OP6 housing on Hybrid ..

    I got the my OP6 hybrid back from the manufacturer but wasn’t too happy with how they machined the hole for the larger wheel.

    For some unknown reason they did not machine right through the housing and left a 1 mm sharp edge on one side.

    I think it will not impact the performance but on the other hand I don't understand why they left that excess material?

    I see soot build-up on that edge right away :(  

     

    Any input welcomed! :)

    Uprated Exhaust Manifold Studs?(RB25)

    I need your input on Exhaust Manifold Studs on RB25DET.

    Is there any benefit of using studs with longer thread on the cylinder head side?

    http://www.ebay.co.uk/itm/Uprated-Set-Kenjutsu-Exhaust-Manifold-Studs-Nuts-For-R33-GTS-T-Skyline-RB25DET-/131706920826?hash=item1eaa581f7a:g:p1gAAOSwqYBWoLFN

    Or would those do as well:

    None of my studs are snapped but I'm going to install a new hybrid turbo and I was tod that replacing the studs while at it would be a good idea.

     

    Thanks
