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.

    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
