ok i have a precision turbo 60 hotside 63 cold.....ls vtec fully built, but not tuned yet still on stock injectors.. just started the engine today and the turbo is not spining at idle, when i rev it up a lil it spins but it will stop a couple seconds later.... is this normal? i also am using no oil restricter and 10w 40 oil, (i have extra bearing clearance)....

 

i just turned on the car and now its spinning... idk what the hell is going on...

 

MAKE SURE HOT SIDE WHEEL IS NOT IN CONTACT WITH THE HOUSING

 

Turbo not spinning at idle is perfectly normal. Larger turbos only spool when there is a load on the engine

 

I love seeing these threads. I dont mean to poke fun, but you're a little too nervous for your own good right now. A fresh turbo not spinning at idle is perfectly normal. The reason i find this particularly funny is because on my first turbo setup back in good ol' 2006, i FREAKED when i started the car only to see the turbo stuck in place lol...

 

That just means you need a ball bearing turbo.

 

wrong room sorry

 

we had a car on the dyno a couple weeks back that had the same problem. turbo locked up about 2 days later. we didnt work on the car so i dont know the history/details etc.

 

make sure it's oiled up and the return isn't bent.

 

Must be something wrong, my hy35 in d16 is spinning pretty nice when idling and keeps spinning some time even engine turned off. Your turbo is not that big that it would need to rev engine to spin it. Trouble in oil line / turbo / both. If u have no oil enough in turbo i think bearing is going instant.

 

its normal. i have a t67 turbo and it does not spin at idle

 

It's normal.

I dare you to search "turbo doesn't spin at idle". double dog...dog.

 

ok some say normal, some say its not.. idk if i should tear the turbo apart or what?... when i turn it on and then off the turbine seems preety free to spin, but when the engine is on it becomes a lil harder to spin......

 

Did you try it with fingers when engine on? :O

 

I have yet to see a turbo not spin at idle on a honda, from a .57 trim to an S372.... In my experiences they never spin well when new, run some pressurized oil through them and they free right up..... I owned 2 BB T67ho's and both wouldn't do a 360deg rotation by hand and after I broke them in they would spin for 30+sec. Make sure its getting oil and then go take a drive and then check it again.

 

yea with the engine on..lol.... i am thinking its that 10w 40 oil.. maybe i need an oil restrictor?????? any thoughts?

 

I had sc50 .48 in d16 and it spinned new. Do a favourite and dont touch your turbo when engine is running, you could hurt pretty bad.

 

Dude...your turbo is fine. If it spools and produces boost under load, then you're okay. You should only worry when:

1. turbo doesn't spin freely under any condition, even when you turn it by hand.
2. blades are touching the housing
3. does not spool under load
4. oil leak
5. blue smoke out of the exhaust

Some turbos need a few clicks for the oil to circulate thoroughly through the turbine. Until then it may not spool at idle. If its a big turbine, it may never spool at idle. This all depends on:

1. Engine displacement
2. compression ratio (higher compression breathes more air causing turbines to spin easier)
3. Turbine size (smaller turbines spool faster and earlier, bigger ones later)
4. age of the turbine (newer ones may need to be ran and broken in)
5. Ball bearing vs. non-ball bearing

If you need it to spin at idle (which frankly sounds silly to me) you should opt for a smaller turbo. Otherwise, if its spooling under load and producing boost and power, then you're good. Shut the hood and enjoy your turbo.

 

^^^ Best advice yet

 

Even taken out of context, this is wonderful advice

 

x2

 

have a nice day

 

*palm to the face and shakes head*

 

i got a screen on there.... i need to get a boost gauge to see if its making any boost.... is there any way to see that the turbo is producing any boost because bov aint working for ****......
sorry for my ignorance... dont know whats normal for a turbo....

 

On a turbo honda, no. The only time the BOV will really function is when the car is under load (actual driving). Sitting at idle and revving the car will not produce positive pressure. This isn't "the movie", so you'll need a boost gauge first. this is good anyway, because then you can also tell if a clamp or hose connector is causing a leak.

1. Get a boost gauge with a strong vacuum source... NOW.
2. Put an actual filter on the turbocharger. you could seriously risk damage. Even dust and sand can destroy a turbocharger. if that happens YOU WILL PAY to fix it. No warranty there if there ever was one regardless of turbo company
3. Close the hood, tune, then drive.
