As above.

Which turbo in the precision range is closest size wise to a gt30.

Thanks

I believe a 5858 is very similar.

Cool. Thought it was about there.

Until you compare the 5558 and gtx30 side by side that is.

Fair enough if they are the same. Just by physical size it's a wierd one

It looks like that GT30 in particular has a smaller than usual turbine housing. But if memory serves me right those turbos are about the same size. You could always look up the wheel specs yourself to find out. From what I remember Garrett sizes theirs a bit differently, so you won't find a precision that is an exact equivalent of the GT30.

Sounds about right, the gtx has a .63 housing and the pt has a .82

Just makes it look ridiculously big by comparison

It's tough to tell, but looks like the GTX also has a weird turbine housing, like a tial or something, and that precision looks like it may be a T4 flange? Tough to say from pic.

That's correct. It's the stainless tial .63 vband housing

Looked up the specs and the in/ex ducers are very similar

The hot side v-band housing makes a noticeable difference as well, as you posted above. Don't let that change your perspective, though. Those GTX setups are no joke. We run a GT30R in our Si and it's a great DD turbo. The GTX is even better!

Oh I know how good they are. It's my mates turbo off his mk4 golf 20vt stroker. Did 537bhp before the mani popped, no joke popped the welds on the inlet manifold.

More to come yet plus water meth and vvt.

Shame they are so damn expensive. 750 for my pt, 1800 for the gtx

Did the floor board fall out too?

Not actually popped off, cracked at the top of each runner would have been a better descriptive
