hmmmm, I will check out that holset. In an ideal world I'd find a k14 in a junkyard for $100 and get it rebuilt. Not looking to spend a lot of money.
I'm still running factory exhaust and downpipe. I kind of wanted to settle on a turbo before I fab a custom down pipe though. Will do a 2.5" or 3" downpipe and exhaust eventually, as well as a small FMIC. Not looking to boost over 20psi. Power goal of 125~135hp.
This is my daily driver, and all my driving is between 1700~3100rpm, so I would like a smaller turbo that will make good boost around 2k rpm. With my t3 and current setup I can feel the boost just begin to build right as I shift near 3krpm, and then rpms drop too low to keep it going. Feels like I'm not taking advantage of the turbo.
holset he211w can make 30 psi at 2500 rpm i think it is.
If you rebuilt your T3 with a 360 degree bearing and did the 2.5" all the way back you should see full boost by 3,000. Mine would start boosting @1,400 or so.
Thanks. I saw some pretty cheap T3 rebuild kits on ebay for $50-60 with 360* bearings. I know they're Chinese... have a better source? I know gpopshop has a good reputation, but didn't see 360* available as part of their standard kits.
360 thrust bearing won't have any effect on spool, only reliability at high boost

That is wrong sir. Not only have I experienced it with my own turbo, the professional turbo rebuilder I go to told me so. Think about it...turbo shaft thrust floating on 360 degrees of oil or floating on 270 degrees of oil. The 270 degree bearing there is a ton more drag which hurts spool. That drag is also friction which could be why they don't last as long as the 270? There is a ton more cushion with the extra oil which is why it both helps with longevity and spool.
