So I recently swapped out my Garrett 57trim for an eBay t3 turbo .60/.63(personal reasons) and noticed that it didn't want to spin while idling. So I tore it apart and cleaned the gunk buildup and figured that might help, but still nothing.

Anyhow, I took the car for a drive and it spools quite nice(as a t3 should).
Ended up tuning the car and at 8psi(same as last turbo) it made 296whp, 216trq revving to 8,000rpms(old setup made 301/216). This turbo provided a BEAUTIFUL powerband compared to the last(200whp@5k compared to 175@5k with last turbo)

Long story short, I'm pretty happy with the results, but still baffled as to why it wont spin properly as my last two turbos did. Any inputs?

Given that it's an "ebay" turbo, it most likely hasn't been balanced from the factory, which doesn't allow the wheel to spin freely & smoothly.

Could be a number of other things as well.

Wouldn't balancing only matter during high RPMs(of the motor AND turbo). I would think that during the lower RPMs, the turbo should have no problem spinning. Idk?..

Check for shaft play? Must be pretty severe if it is so you should have no problem noticing

I would suspect that it is probably a turbine bearing. It probably not the greatest quality. Think in rotating thoughts, when you have a bad wheel bearing the wheel is harder to spin most of the time, but once you break static friction its not that bad. An unbalanced wheel will still be just as easy to spin, but vibrates at higher rotation speed. This is just proof about ebay turbos. You can still make power with them, but its like pushing 400hp on stock internals. You can do, but dont excpect it to last long lol. But who knows you might be one of the lucky people and never have a problem for as long as you own the car. Ive seen an h22 make 522hp on an ebay turbo, but it only lasted a few months before the whine of death.

Put a screen or something over the inlet to your intercooler. Not saying the turbo will grenade, but it's happened before.

The lower trim turbos will spin sooner and a higher trim don't spool until later. I guess it's just not moving enough air at idle. It worked out, so it sounds like you don't really have an issue anymore.

I meant nothing by it. I personally mainly run ebay turbos simply because 99% of my cars are budget built. I dont see why people talk so bad about them ive only had 1 go out on me personally but i usually cant keep a car for more then a month before i get bored and want to do another. Its like alot of parts that you buy, you pay alot for the name that's stamped on it.

Ebay turbo's are nothing but cheap chinese **** that has been thrown together by someone that could not give a **** if it failed or failed and took the engine out. By buying there **** all your doing is supporting it... meaning even more will start flooding the market.

I fail to understand how anyone could be proud of there car or work when they choose to run this ****... and no i never have run one... i wouldnt lower myself to that level.

Dioxine

Im proud of every car i build cause its a piece of me. You dont like them fine dont use them. But this guy just made 300hp off one. Numbers dont lie . You obviously didnt read my first post so before you go off being butt hurt stop and read. Buy what you can afford and what you need, im not building race cars im building weekend fun cars and i will use what i feel is right for my setup. I dont have endless pockets and i have a family to support and they come before my car. And ive never lost a motor and ive built well over 50.

rich7777

Sorry, no i never read your first post. I just scrolled down the page quickly read your last post. Thats just my personal view on them anyway... and of course we're all entitled to our views including your self. Its not that i'm "butt hurt" its more that i'm a bastard when its come to anything "made in china" lol. Take it with a pinch of salt, i get most of it from my job as i'm constantly dealing with **** that has come from China. The way i see it is that it could have been made over here and 1. Been done to a much better standard 2. Give a British person a job.

See what i'm getting at ?

Dioxine

Yeah i got what your saying. Thanks for taking what i said in and not turning this into a huge fight on someone elses thread lol. I would rather have a garret but i would have to save up for a long time and with my luck i would drop the money for one and have an oil pump fail or an oil feed line break and i just destroy it lol. And i agree outsourcing is terrible (but thats another discussion topic). But if i take the time to put crower rods and skunk2 cams and acl bearings etc. in my car then im going to go with a name brand turbo. Cause why stop half way. But most of my boost builds have just been clean stock internals and i wanted a quick boost (not the right way parsay but i knew that before i started). But i never opened the hood and when people asked what brand my turbo was i would change the subject lol. And i would never slap a decal on my car that said ebay turbo inside lmao.

SQ is the SQUAD

is it just me or do most turbos not spin at idle? just cuz u mentioned its an ebay turbo everyone is going to junp on that as the problem.

SilverEk3dr

My gt35r ball bearing turbo would spin at idle, and for literally almost a minute by itself after you turn the car off. Same with my old bosses race car with a gt4202.

Now imagine if you installed a real Garrett turbo. It would have spooled better an made more power than the eBay Chinese unit. Other than the Garrett 57 trim
Being blown why on gods green earth would you swap out a Garrett turbo for an eBay turbo

SQ is the SQUAD

ive only had one car, sabb t3 mini me. dident spin at idle, turbo had no shaft play and worked fine.............

LightningTeg

Surprised the little guys arent spinning at idle.

My billet 6262BB spins for like 30 secs after turning the engine off from an idle.... lawl.

But yes, I had an eBay "57 trim" and it wouldnt spin at all @ idle. Surprisingly though, it lasted 15K miles and is still going strong on a friends motor. Made 304/245 on a bone stock LS @ 14psi.

My eBay t3/t4 57 trim spins at idle and for like 20 seconds after I shut the car off. It didn't spin at idle when it was brand new though, took a couple pulls for it to break in or something I guess.

pics or it didnt happen...

I'll be happy to take a video if you don't believe me. Problem is, it's dark outside right now.

A straight t3 like that should most def. spin at idle... hell my Holset He351cw (60mm) spins freely at idle no issues.... I think this is just a fact that the ebay turbos are absolute junk. But hey it builds boost and makes power so who cares.... you payed less than 200 bucks so you get what you pay for.
