Hirdy Member 31 Member For: 5y 11m 1d Posted 26/04/19 10:39 AM Share Posted 26/04/19 10:39 AM Hey all, just St want to know peoples opinions on the cheap EBay turbos, I see there is multiple turbos on there for around $350 and want to know if anyone has used one and how it went and how long it lasted for??? My turbo is getting a little noisy so I’m just starting to have a look now before it’s too late, not keen on spending thousands on a new turbo. Car is a Bf series 2 xr6 turbo, currently tuned to 420rwhp. I can here turbo spinning down once car is shut off Link to comment Share on other sites More sharing options...

You can get a genuine chra for about a grand. Link to comment Share on other sites More sharing options...

You're best off retaining your stock housings and replacing the CHRA if the bearings are noisy or the shaft play is so bad that the wheel(s) are touching the housings and fixing what caused the problem in the first place (most common cause is a blocked oil line filter causing oil starvation or oil coking).

Hirdy Member 31 Member For: 5y 11m 1d Posted 26/04/19 10:48 AM Author Share Posted 26/04/19 10:48 AM Ok so is there a big difference between journal bearing and ceramic? Would I notice any less power or other between the two? Yeah at the same time I need to replace turbo feed line as it is still the original type. Car has done 195000kms and was a x nsw police car so who knows if it’s original turbo, I have owned it for maybe 18 months and it has worried me the whole time Link to comment Share on other sites More sharing options...

It would be fine for your power level but you'll need to block off water supply/drain lines and take some precautions in your driving methods to make the turbo last a reasonable length of time. ball bearing is quite good and good enough for your current power level. It is more expensive than journal bearings but will retain your current setup. ceramic ball bearings are the best (newest) design and is the most expensive.

finnas Gold Donating Members 105 Member For: 14y 3m 7d Posted 26/04/19 01:24 PM Share Posted 26/04/19 01:24 PM I got a ebay turbo in the mail. gtx3576 (power spirit) for 1k. I tossed up between the gt3582 journal bearing for 360 odd and the ball bearing on for 600 odd for awhile. My turbo was making the same noise yours is while it was spinning down. So I decided replace it. Baseline was a used gt3582 for around 600-800 depending on condition. But that was pot luck same as trying an ebay turbo. I guess we will see how it turns out.

Hirdy Member 31 Member For: 5y 11m 1d Posted 26/04/19 08:33 PM Author Share Posted 26/04/19 08:33 PM (edited) I found a eBay CHRA cartridge core with dual ceramic ball bearing and billet wheels for $500 shipped , direct bolt in so am thinking of going this way. Has anyone tried this type before? https://www.ebay.com.au/itm/STAGE-2-GT3582-Turbo-Dual-Ball-CHRA-Cartridge-Ford-Falcon-BA-BF-XR6-FPV-F6-/112343377358?

I have a Hypergear replacement turbo on my RTV ute and am happy with it. Plenty of the RB crowd use them with good results as well. 1 Link to comment Share on other sites More sharing options...
