finally got all my engine back together today after the big rebuild (rb26dett). didnt think anything of it when the turbos (2860-5's) had been sitting it had oil leaking out of them and we just assumed it was because they had been sitting for so long. but when we took it for a drive today just blew a shit load of smoke. and now they are both leaking oil. not happy

what do you mean leaking oil? ...when mounting these turbos did you use a oil restrictor? if not, try to fit a 1 - 0.8 mm restrictor to the oil feed. The smoke may go away. That is unless if you are shure that the seals is not gone.

If oil's coming out of the inlet side with out any obvious shaft play then it means you've got an oil drain related issue. Check the drain pipes make sure its not kinked, bend or capable of storing oil.

Also remove and check the drain adaptor if you or your mechanic sealed it up with silicon instead of gasket.

when we pulled the turbos of the car the were fine and hadnt been leaking oil. They have been sitting in a sealed box for about two months why the motor was bein built. and yeah when we put them back on they have devoleped a leak. but also when we pulled them out of the box the had been sitting in there was oil everywhere in there so would i be correct in saying and hoping that just new seals and no major expense

considering you can see it droppin from the turbos and the whole rest of the engine is dry. yes i am very sure it is comin from the turbos

did you replace all the copper washers?

its ifs dripping/dropping from the turbo i would say you have a leak in one of the fitting going to the turbo and that the turbo themselves may be fine

      M35 Brake caliper replacement

      By Waders360 · Posted

      I've looked up the parts number (41011AL501). It's around $700 OEM. Usually our Infiniti G35 here in Canada have interchangeable parts with my Stagea but the parts number are not the same. I have looked around and it seems the JDM 2005 V35 Skyline (which is the same as our G35) has the same caliper but I cannot confirm. And I can't find a repair kit. The inner brake pads drags on the rotor, seems to be rusty piston. Thanks for the info by the way

      This coupled with 6-9 speed autos with ridiculously short gearing is why these modern shitbox cars always seem so fast off the line. If it wasn't for those things, Raptors would not seem fast. The problem we have is there is a driveability gap between a more gentle take off and a wheelspinning sideways launch. The difference between ankle flex required to achieve one and ankle flex required to achieve the other is about 0.5°.

      Yeah I think I'm also with the opposite here. It's 'hard to keep up with traffic' because in the real world I'm accelerating with 15% throttle and they are pinning it. It feels like I'm being an overt dickhead at anything above 15% throttle, so the car sounds like I'm being an overt dickhead to keep up with/get ahead of traffic when I'm really just trying to drive with traffic. There would be no issue 'keeping up with traffic' if we used the same level of throttle input/aggression to drive around. People really do just drive around with their foot nearly pinned in econoboxes.

      To be fair it's the other way around. 300kw is boring in a modern Golf or BMW. They are so competent / well-engineered / devoid of emotion that you have to go stupid fast to feel anything. Whereas the <300kw RB still makes all the right noises and it feels good to drive. Can pull off at the lights with the turbo whooshing and the blow-off pssshing and feel like the coolest kid on the block. Just don't look to the side where you'll see the bored housewifes in their shitbox Yaris/Corolla/Camry that kept up because you didn't go fast at all

      300kW is so boring in a Skyline, you'll get spanked by someone's mum's Golf with Alibaba pipes, and an email tune.
