Holset he221's! - MFSuper90 - 08-27-2013
I just saw were there are a couple Holset he221's for sale on ebay, brand new! Not mine, but I would grab them up if I didn't already have my hx30.
Be a nice little charger for a om617, flow a pretty good amount, and sound wickkkkked!
Just thought I'd let yall know

T25 flange right?
RE: Holset he221's! - Mark_M - 08-28-2013
Yes I think they are T25. Often wondered what these would do on a 605? Obviously wouldn't be monster power but maybe a good street turbo.
RE: Holset he221's! - MFSuper90 - 08-28-2013
I think they'd be a very nice street charger for a 605, they flow a considerable amount compared to any charger close to their size.
I'm pretty sure the bolt spacing is the same on a t25 as a t3, except t3 holes are wider

Guess I can let you know next year, just got my tracking number. If it's garbage it's your fault
lol. I have done the calcs and read as much as I can find on these and I can't come up with a reason why it shouldn't be a good Street turbo. It won't win any dyno queen awards but it should be a good laugh on a 1000kg car

They sound sooo sweet, at the hx30 on my car does, and the he221 maps look much better than the 30's.
Plus, just from eye balling it, I think the one you got has a billet wheel in it!
Kinda jealous actually...

Negative ghost rider on the bolt pattern. I had a HE25 on my car for a while, was a bit small. HE221 is probably great for a 601/2

Forced put one on something if I recollect correctly. I thought two of the bolts he used the original studs, but the other two were a short?

The one he has is a t2 as I just found out. I thought most were t25?
