I recently purchased a manifold with a GT35R turbo. The person that is selling me the turbo is going to be sending me a Precision GT35R turbo and I just wanted to know how it compared to the garrett? I know that they are pretty much the same company, but one is supposed to be better than the other right? any inputs please?
thanks

Same thing...

Isn't the turbine housing different?

If I remember right in one of my old threads arturo addressed this and he stated that... The inards of the turbo are precision and that the housing of the turbo is garett and that there are two housings the e-housing and the s-housing, the s-housing being the bigger one.

I could be wrong tho...

I would guess its the other way around. CHRA and wheels are Garrett and housings are precision?

they use precesion housings and garret internals.

I personally would have gone for the garret genuine part for the casting on the exhuast side is much nicer then the Precesion counter part.

FYI, Precision is the largest of all the Garrett Performance Distributors. On the GT35R, we use the Garrett CHRA (center housing rotating assy) along with our own exhaust housing, backplate and compressor cover.

One of the reason why we do this is because the out-of-the-box Garrett GT35R has exhaust housing A/R's (0.82 and 1.06) that are simply too big for 4-cyl street applications. Our own housing has a a 0.63 A/R, better aerodynamics and is now available in either a 4 or 5-bolt pattern on the discharge side.

We also use a CNC machined aluminum backplate and have a wide variety of compressor covers available, e.g. a T04E (3" inlet, 2" outlet), T04S (4" inlet, 2.5" outlet) or a T04S ported shroud.

The Garrett GT technology offers greatly improved aerodynamics. The dual ball bearing design offers significant advantages over the older journal bearing design not only in quicker spooling, but also in terms of longer life and increased durability. These are also rebuildable through us, which is another important advantage.

Another manufacturer offers a single, or hybrid ball bearing system which uses a single ball bearing on the compressor side with a traditional journal bearing. Since the single bearing can only take thrust in one direction, a thrust bearing is still necessary and drag on the turbine side journal bearing is unchanged. With the Garrett system, the rotor group is entirely supported by ball bearings, so efficiency, performance & durability are maximized.

We've gotten a lot of compliments not only on the performance, but also the appearance of our product.

Hope this clears up some of the misinformation. Please call if I can offer any clarification.

Could the T04S ported shroud compressor cover be ordered togheter with the 0.63 A/R 4 bolt turbine housing? Would this be a good combination for a 2 Liter street car?

Thanks

Yup, you can get the T04S ported shroud with a 0.63 A/R. No problem. Call if we can provide any other info.

I have a Precision turbo Zulu, its fine. You need to get set back up so I can take you out before I sell the beast(if I do)

I have recently sold two GT35Rs from Precision to customers and they are PURRRTY!!! Seriously the housings were very nice, once being an H cover or Ported shroud which was really nice. The customers have been very very happy with their purchases!

T04S Ported Shroud=H Cover? Correct? Or are we getting S covers with an anti surge inlet now?

Rod Short

Thanks for the question. TheH cover has a 4" inlet/3" outlet. The T04S ported shroud has the same inlet with a smaller 2.5" outlet and the anti-surge ring incorporated into the inlet of the compressor cover.

Thanks for clearing that up Rod. I was unaware you guys made the T04S ported shroud, you guys need to keep me up to date on this when I call everyday.

Is the H cover compatible with the same backplate as the S cover? How about the overall diameter and thickness of the volute? And the A/R of the H housing? Basically, what are the advantages besides the 3" outlet?

The H covere is HUGE compared to the S cover. Like comparing E cover to S cover BUT may be more actually. The H I BELIEVE also has a 10% greater efficiency as the S as the S is supposed to have over the E housing also. Hope this made sense!?

turbopimp

Ok, but the S and E covers can bolt onto the same backplate... just wondering if the H can as well. I remember seeing the H somewhere and yeah, that sucker looked HUGE

Unfortunately different back plates, I am 90% sure on that , 99% actually. UNfortunately it is not like a turbine housing where you can just swap them out with no other changes.

Rod Short

That's correct, The T04E and T04S covers use different backplates. The smallest turbo we make the H-cover for is the PT63 with the P-trim wheel. As for the T04S ported shroud cover, we only made a handful of them. We should have these back on the shelf in March.

I thought the E and S covers were interchangeable for a given trim, am I mistaken?

Rod Short

They are interchangeable on the turbo, yes, but the backplates are specific to the compressor cover. In other words, you have to replace the compressor cover and backplate together. Hope this helps.
