experience with X trims?

[JDSfastGN]

I know its kinda old school compared to whats out there but I just had the dbb 70mm ITS turbo rebuilt for our T and we installed an X trim exhaust. It has a .85 PTE housing. It used to have a Q trim. What kinda times on iron heads have people run on a similar setup? Im hoping to see the track on the 8th with the new NL converter and the dbb70X trim? Thanks guys.

I had an its 70 x trim with a precision .85 housing for awhile. Ran in the 9.7s with a stock stroke 109 and gn1s. Needed around 30 psi to run this number. It was a greaat turbo until it chucked an exhaust wheel. Since its was no longer around, it was going to cost new turbo money to get fixed so I bought a new turbo.

Mine was a journal bearing though.

Hopefully this exhaust wheel doesn't come apart. So I guess I can expect bottom 10s out of a well sorted out iron headed combo. I guess we will see. It ran 101 in the 1/8th on 24 psi on the old converter that had it pushing 5900 through the 1/8 mile traps. I am looking foward to seeing how it does with my new n/l converter.

Who currently rebuilds ITS DBB 70 turbos, mines a P-trim.

It only has 40K on it but I want to be ready if it needs it someday.

You can get a hold of Rick Head at Exile Turbo.

I think I asked him when he first started up, and he said he was only dealing with Garrett turbos.

I'll shoot him an email.

Thanks for the info. :smile:

Yeah you should be able to get your goal easily. I would run my its turbo with about 23 psi and run low 10s all day long. It would do 6.5s in the 1/8th at that level.
215/220 hydro cam (I think the cam was mismatched for combo)
Gn1s that flow 260/245
Non stroker
11.0:1 a/f
21 degrees of timing
Shifted at 6k
Ran 110 octane turbo blue

I think those are most of the main details. Hope that helps.

I just got an email back from Rick and he says he can service them.

Would I ever steer you guys in the wrong direction?
Please don't answer that!
