Hi guys... I'm looking for a direct bolt on ball bearing turbo for the 1g....any recommendations would be helpful.
Upgrading from tdo5 20g.
 
They are expensive but as for my first time recently owning a ball bearing Fp/Xona rotor turbo, I can vouge they are absolutely worth every penny in my opinion and many others! (Exceptional fitment quality and customer service!) So if you send it for the ball bearing black and its capable of your goals I'm sure you will be more then happy with the choice!
 
Bolt-on and ball bearing pretty much means either a BB FP Black, something suboptimal from PTE, or buying something used, or getting a custom machined turbine housing. There's no other ball bearing options being sold new currently in a Mitsubishi footprint. If you're concerned enough with it's performance to insist on ball bearing, I'm confused as to why you'd also insist on a restrictive stock turbine housing.

If you are able to find one, an FP3052 or FP3065 would be a natural step up from a 20G and were both available in ball bearing CHRAs.

Another option would be the .63 A/R turbine housing from PTE. I don't know much about Precision's line up, but as long as you use one of their BB CHRAs with their 62mm turbine wheel, that gives you a few more options for bigger than 20G, bolt on and ball bearing.

Here's another option from FP:

http://www.forcedperformance.net/xona-rotor-5757s-ball-bearing-turbocharger.html

Bolt on Xona rotor/FP turbo, go to drop down box for turbine housing and select FP 30 series housing. I believe eventually FP will be coming out with a bolt on DSM zero, but I don't think anyone knows when this is supposed to happen.

Or as mentioned above the FP black BB option or look around for used 3065 or 3052. I have the JB black and I really enjoy it, I'm sure BB would just be better.

Choices are slim when it comes to direct-fit and ball bearing. Keep in mind ball bearing is purely a durability mod and doesn't always translate into better spool or response when comparing two units of identical wheel specs...the only time ball bearing should really be necessary is when the plans for the turbo include it being over-driven to hell (high boost, large compressor on a small turbine in a small a/r housing) or lots of on/off/on throttle application such as a road course. Otherwise they have an extreme intolerance of oil contamination and easily cost three times as much to service than a comparable journal bearing unit.

Thanks for the awesome information. Here I have been lusting after 6466 BB turbo and scared of the price. But a standard 6466 will serve my goals just fine. Thanks!!
 
I am still worried about PTE turbos from years past bad luck. But I won’t argue that for there size and spool they put down some serious numbers.
 
I'm definitely not a fan of Precision...which is a shame because their compressor packages perform very well in their given wheel sizes.

They need to revise everything. They have the power to do it- I have no clue why they insist on using Garrett T04 bearing housing and fitment tech from 1967. The thrust system on the journal bearing units finally got a thicker thrust collar they've needed for the past decade or more. The seal plates bolt in from behind on the journal bearing models with four tiny little 1/4" x 3/4" bolts threaded into an aluminum seal plate...that's literally all that holds the entire two halves of the turbo together. Compressor cover is secured with (6) 5/16" x 3/8" bolts that catch about two threads...if you can tighten them more than once without stripping all six of them it's a miracle. Throw some typical corporate customer service and turbine heads that like to eject themselves while on the dyno before they ever see track time and I don't understand how people keep going back.

When you compare what you're getting there to a Xona turbo for similar money with it's own machined stainless bearing housing, it's own bearing system design, a v-band clamping the bearing housing and turbine housing together, a snap ring holding the compressor housing in place...or a Borg unit that's tough as nails for half the price, or a Holset that's probably the most-durable journal bearing turbo in existence- soon you begin to see the only positive feature of the Precision is their power potential.
 
I will absolutely vouch for Holset till the day I die. I went from a 20g to an HX35 and was amazed. HX40s flow more and are just as durable. I was using bullseye powers direct fit exhaust housing with my hx35 and it def flows enough to scare me at 30 psi...plus you can find holsets so cheap (think 400 dollars for a nice shape hx35).

At that rate you could kill 5 holsets before you get above the price of certain BB turbos.
