Ball bearing vs journal? Journal bearing on3 turbo is much cheaper.

That was me

Ball bearing is in the $6xx where as the journal bearings go for $299-$325. While I have not looked lately, I remember the TC78 ball bearing being a good bit more.

Yep, IIRC when i bought mine a year ago, they were listing for 500 more then a journal bearing turbo.

I didnt think we needed all that fancy ball bearing stuff in the V8 world, lol.

What's the price they gave you? I emailed them and asked if they still made the non-ball bearing T76 with a .96 AR and they had a batch in progress. I didn't ask about the price as I assumed it was still going to be in the $300 range.

They also make a 1.0x AR but probably don't have it in stock.

As told by one of our sponsors, a 65mm exducer will support under 600hp. Not sure if thats fw or rw. The 68mm exducer will support above 600hp, again not sure if thats fw or rw.

It is going to be a minute on mine. Customer cars come first, and we have to finish shoe horning the 5.3 into my Wrx. That part is almost done. Hoping to have the transmission finished in the next month or so and then off to get the custom driveshaft made. The single on the 5.3 got scrapped, but that motor and transmission will eventually go in a 71 camaro.

No dyno time, but i put a video up of it on the street. the 76mm with the .81 AR housing it putting out 17psi on my stock ls1. It will definalty choke the motor out over 6k, as I'm at full boost around 3600 rpms.

The bigger problem is that the exducer on the exhaust wheel is only 65mm. I wish it came with a bigger exhaust wheel, but the 76 should do fine in a rear mount situation.

Mine is going on a 5.3 w arp stuff, sto k heads, vicjr, lpe cam.

Looking for 700wheel, I got the 1.0a/r

I don't see the 76mm listed with a housing bigger than .81 does it cost more to get the 1.0 housing

Just bought my 76mm journal from them for $348 shipped and they said they sell the 76mm's in .81ar and .96ar. Although the housing says .81 I know for a fact it's a .96 but they must not mark them separately. Going in my 5.3 s10 this spring so I'm hoping it'll make some good power
