ok, this is exceptionally weird

the past 2 weeks or so whenever i have turned the car on, the turbo has spun fine.

although today i modified the oil intake as it was leaking the old way.

and when the car starts, the turbo spins and then just gradually slows down and comes to a COMPLETE STOP

and on idle, it just sits there, no spinning.

give it some juice, and it spins fine, but let it fall back to idle and it slows to a stop.

this kinda freaked me out, because i am just about ready to get the exhaust made and thats all that left to do.

and now this.

so please boost help me.

ok, no there is no evidence of scratches on the walls, so the blades are not hitting the side. and i cant move the shaft so there is no shaft play, although i can easly spin the turbing, and both the intake wheel and exhaust wheel have no obvious problems, everything looks 100% perfect. but it just doesnt spin at low revs.

its weird

its a new T04e turbo

HELP

its a china turbo, reason being that i want to see how they work as i am using the car as a track car only

wastegate is fine, working as it should.

as soon as i give it some herbs it spins, the boost guage indicates boost is being made and it appears to be fine.

when i stop, it just chills and slows down

its common for the china stuff to stop spinning at idle....

some turbos spin at idle, ball bearing types would be easier than normal but all comes down to exhaust wheel getting enough gas to spin and engine creating enough vacume to drag the wheel around

if turbo is large then prob wont spin at idle unless its got sufficent gas to turn it

track car using china turbos

oh the humanity :)

Hope it holds together and doesn't make mince meat out of your motor

well experimenting with different turbos and sizes before making the final selection, and simply do not have the budget to get the top of the range for all of them.

as much as i would like to lol.

    • 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.
