My plan was to upgrade what ever turbo I get now into a red. Figured I would send it to FP while I'm waiting on my shortblock to be built.
Thinking about it realistically that might only be in a year or so considering.... Maybe I should just get the red and try my hardest not to blow my **** up still a question of bb vs jb though.
I wouldn't waste the time of upgrading a turbo. Sell the old one and buy new when the time comes. Always go BB if you're willing to pay for it. The difference in transient response is immense.

To the OP , if your engine is worn out or doesn’t have the proper crankcase ventilation it could cause the turbo to not drain well.
With the holidays coming up Fp will most likely will have things on sale. I would buy a new turbo also. A BB turbo would be nice if you are going to run it all the way up or take the car to the road course. Being a “small “ turbo I wouldn’t be too concerned about transient response.
But after running an BB hta and htz red, I would recommend an oil pressure regulator if you go that route. The 4g63 makes a ton of oil pressure and running a thick oil could make things worse . My current htz gets 2psi at idle and 10-11 psi at wot at 180’.
Start up oil pressure used to be 30+ without a regulator and now after adjusting the spring pressure its 14-15 psi cold.
Another forum member was told by FP that even 5psi of oil pressure at WOT would be ok.
Right now I'm leaning more on the BB 54 green. I think its the most comparable to the BB HKS turbo I had. I'm pretty sure it will give me more up top then the HKS turbo did. The red is super tempting, but I don't think I'm ready to move up to that. When it comes time to rebuild the motor I am planning on a Mivec Converted High compression ER 2.2, and then I think the Red will be just what I am looking for. Of course I lost the paper I wrote everything down on, but the compression test came back great so she has some life left in her. I haven't pulled the trigger on anything yet, still thinking about it. With black friday sales coming up too I think it would be worth it to wait a couple weeks anyway.
FP includes an oil feed kit with the BB turbo's which includes an in line filter with a .020" orifice, is that comparable to the oil pressure regulator you guys are advising?
You plumb the OPR in so that it feeds the .020" restricter which then goes to the turbo.
IIRC you have an Evo9. I would just buy the red now.
Actually I have an 8 and I am still running and plan on keeping for now the stock MAF/Airbox. I did remove the honeycomb on the MAF so no worries about it getting sucked in, but I did read something about possibly damaging the turbo with the factory airbox. You guys know anything about that? Also any recommendations on a regulator?

Turbo smart is the only oil pressure regulator.
And yes, using the stock airbox past ~350whp or so can start to make the turbo struggle. You may be running it a higher RPM/pressure ratio than you realize and shortening its life.
@Biggiesacks Kinda of off topic but have you seen results for the new HKS turbo? GT III RS, it might be an option since it seems like you want the fastest spool and most power you can get. Looks like stock inlet size.

Your good its pretty on topic . I have looked at that turbo, and my reasons for not really considering it are for the most part completely meta and not relating to that turbo itself. I don't really want to rag on HKS, but I feel dealing with a company I can communicate with directly and that can provide me with after sales support is an important quality I value more now then I have in the past. I can be more specific if your curious but I don't want to just jump into rant mode
After doing a bunch of reading on turbo failure a light bulb went off and I think I figured out how I killed this turbo. Like an idiot I replaced the Valve cover to Intake manifold PCV hose with some silicone hose that 1. I'm sure was collapsing under vacuum and 2. Is not fuel oil compatible. Expensive lesson learned*.

from what I can tell its basically the same as Radium uses with their catch cans.
*its the best theory I have so far on why this thing died, it's surely a problem regardless that I need to fix.
That wouldn't kill the turbo. It would cause it to leak, but you could fix that issue and the turbo would stop leaking. You said you have excess shaft play, that's not caused by a plugged PCV..

Sorry I must have done a bad job communicating, there is almost no shaft play, certainly nothing I would consider excessive. The video I posted does a bad job at visually demonstrating the shaft play because the turbo isn't anchored down and is just flapping around while I wiggle the shaft.
That all being said, you think I should clean up the turbo and try slapping it back on?
I just pulled the turbine housing back off and measured shaft play. My methods were not what I would call super accurate but I'm pretty confident I have ~ 5 thousandths of shaft thrust play.

still a question of bb vs jb though.
