UPDATE - Jut got off the phone with one of the tuners at TUNE HOUSE and he confirmed that they have easily gotten 250 - 270rw/kw on R33's with the Precision Turbo 500HP highflow, and the $200 you save from the GCG item can go toward an EBC or any other mod...

UPDATE- Just spoke to Precision Turbo's and have been advsied that they are also offering FREE postage back to you as well as all gaskets and bolds to bolt back on...

Dyno sheet will be available on this thread on friday... so keep an eye out!

Hey Sarkis do any lines have to be modified?

Oil ect...

[Ol_Mate]

whats the go with compressor surge on these highflows? Have they had any problems?

[QRI05E]

NYTSKY - Nope they use the stock oil and water lines... New bango bolts are supplied cause the thread on the new Garrett core are different to the stock ones... this is COMPLETE highflow and only uses your exhaust and comp housings... the rest are brand new Garrett parts.

Oi mate - I spoke to them today regarding any surge issues and they said in the past 8 years of RB turbo highflows they have done (10 per day = 25,000 units at least) that they have NEVER had any surge issues with the RB25DET highflows...

TUNE HOUSE told me that 3 of their recent R33's have landed a 270rw/kw with these highflows using Haltech ECU's

Put me down for a R33 S2 Highflow then

[QRI05E]

Done!

[Pauly33GTS-t]

PM sent, I want in.

[QRI05E]

Done!

[Pauly33GTS-t]

scratch that, alternative sourced

EDIT: take my name off take my name off aaaaaahhh! lol...

UPDATE - Dyno graphs added!

I couldn't believe the results when i first saw the dyno graph... I cant wait to get one of these babies! Common guys place your orders while these prices last...

these look awesome, however I don't understand why when you get one of Slide's hi-flowed turbos he says it is compulsory to drill out the oil restrictors to allow more oil to cool the turbo, yet these and CGC don't tell you to do this.

[QRI05E]

Cause Slide's high flows are Journal bearing which require a constant oil pressure and flow...

Precision Turbo & GCG highflow's are Ball Bearing same as the factory turbo which means no moddification of the water or oil lines are needed. In other words by going to a journal bearing highflow, you are "down grading" in quality to your stock turbo...

25,000 RB Highflows????

And then this gem:

In other words by going to a journal bearing highflow, you are "down grading" in quality to your stock turbo...

A journal high flow is an upgrade in every sense of the word.

Sorry mate, ive got to disagree there.

there are too many differences in opinion about these turbos, how could anyone feel comfortable getting them.

i would rather go to GCG or Slide just because i know that they will make the numbers because everyone else on the forum who wants a highflow has gotten one from either. and at least Slide is a trader and a member long before that, so we all know he isnt going anywhere.

also, i just have to add that 99% of 32 and 33 gtr turbo's are journal did nissan downgrade to them for any reason?

same highflows with the same wheels producing the same numbers.. there is no difference and the fact of the matter is that ball bearing turbo's do FAIL (you have constant metal to metal contact).. journal bearing turbos ONLY fail when oil feed is interupted (there is no metal to metal contact).

and what's more, with the price of BRAND NEW garrett turbochargers these days which have an internationally backed warranty from a massively respected company, why would anyone spend MORE than the cost of a new garrett on a highflow no matter WHO makes it?

[Ol_Mate]

I disagree that its a "downgrade" completely. However, I don't think that the comment justified you completely writing off ball bearing highflows from this particular company. You gotta remember that was a comment from the user, not the company.

Why? Because if you're not a trader on SAU or have Sydneykid's seal of approval then you're automatically a fraud?? These aren't good enough reasons to dismiss these turbo's. If you rang around like I have, you would find that they are quite reputable.

also, i just have to add that 99% of 32 and 33 gtr turbo's are journal did nissan downgrade to them for any reason?

No, not at all. Journal bearings better suited the applications on the RB26DETT. Just like ball bearings were better suited for the RB25DET.

same highflows with the same wheels producing the same numbers.. there is no difference and the fact of the matter is that ball bearing turbo's do FAIL (you have constant metal to metal contact).. journal bearing turbos ONLY fail when oil feed is interupted (there is no metal to metal contact).

Whats the point of this comment? Are you trying to say that journal bearings are more reliable than a ball bearing in a turbo application? Where's the evidence saying that an oil feed failure to the turbo is less likely than a ball bearing failure? At the end of the day, everything fails, it's just a matter of time.

and what's more, with the price of BRAND NEW garrett turbochargers these days which have an internationally backed warranty from a massively respected company, why would anyone spend MORE than the cost of a new garrett on a highflow no matter WHO makes it?

If you can find me a BRAND NEW Garrett turbo rated to 500hp that is a true bolt on replacement (ie. no stuffing around with oil and water lines whatsoever) for the standard item for under $1550, I'll buy it.....

That simple...

This is true but from the misleading information provided it is quite worrying to see an ambassador of a business trying to push its products and not knowing much about it to help us make a discussion on them.

Why? Because if you're not a trader on SAU or have Sydneykid's seal of approval then you're automatically a fraud?? These aren't good enough reasons to dismiss these turbo's. If you rang around like I have, you would find that they are quite reputable.

If you look at the above statements made most of them were stolen from Sydneykid.

I never said they were a fraud at all but as i have written above the information wasnt all that assuring.

No, not at all. Journal bearings better suited the applications on the RB26DETT. Just like ball bearings were better suited for the RB25DET.

Whats the point of this comment?

How is that a good generalisation of what turbo's were deemed better for an application?

Why would journal better suit a GTR (Certified race bred cars) then a much lesser sports coupe?

This was a very bad example on your part.

As by that statement you would be leading people to beleive that Journal are better suited to cars that require harder working better performing gear.

Are you trying to say that journal bearings are more reliable than a ball bearing in a turbo application?

Didn't you just say that?

Where's the evidence saying that an oil feed failure to the turbo is less likely than a ball bearing failure? At the end of the day, everything fails, it's just a matter of time.

That is exactly my point and why myself and (im sure) 2rismo pointed out a silly comment like this:

In other words by going to a journal bearing highflow, you are "down grading" in quality to your stock turbo...

Very missleading and defaming (of Journal bearing systems) information that most people viewing this thread might not know about.

If you can find me a BRAND NEW Garrett turbo rated to 500hp that is a true bolt on replacement (ie. no stuffing around with oil and water lines whatsoever) for the standard item for under $1550, I'll buy it.....

Nope its not possible but the point is who cares about ball bearing when there is no real difference to journal? Show me the differences between dyno sheets between these highflows in particular.

Cheers

First of all, my apologies for the misconception of my comments.

What I meant was, Ball Bearing turbos are superior in durability than journal bearing turbos. This comment is not only stated by me, but by MANY knowledgeable SAU members and performance specialist. It is my understanding that ALL RB20, RB25 & RB26 come with ball bearing turbos from factory, therefore a journal bearing unit will be a downgrade to a certain degree of durability.

Guy’s I’m not trying to say that Slide’s or GCG’s turbos aren’t good, in fact I think they are one of the best options out there! However, from seeing the prices on ball bearing highflows, I have organised a Group Buy with a highly credible workshop called Precision Turbochargers who cater for ball bearing as well as journal bearing highflows. Slide’s journal bearing offer is at an unbeatable price therefore I have not tried offering anything in that range. On the other hand Precision Turbo’s are offer a similar product to GCG at a better price and that’s what im trying to offer all SAU members. An alternative to other manufactures with the same quality and service.

I think I probably should have explained myself a little better in regards to journal bearings and the RB26DETT.

In the late 80's and early 90's, ball bearing technology hadn't progressed to the point where they were suited to high RPM, high temperature conditions found in turbochargers. Also cost of manufacture was a big issue.

So, as I'm sure you know, the majority of turbocharged vehicles manufactured at this time ran with a sleeve/journal bearing for reliability, friction and cost issues. They did so for years with great results.

But as ball bearing technology progressed, it was found that they actually exerted less friction on the shaft than a sleeve bearing. With less friction they were able to make the turbos more efficient and more responsive than they ever could with journal/sleeve bearings.

As far as I know, and correct me if I'm wrong, R32 GT-R's had a sleeve bearing turbo setup all around, R33 GT-R's had a ball bearing turbo but the R33 N1 remained sleeve bearing and R34 GT-R's had twin ball bearing cores all around.

As a result, I'm not sure what you are referring to here:

also, i just have to add that 99% of 32 and 33 gtr turbo's are journal did nissan downgrade to them for any reason?

Anyway, I was just trying to clear up the fact that in the early variants of the RB26DETT, sleeve bearings were the go due to technology of the time. But as it was further developed ball bearing cores were adopted due to the lower friction they exerted on the shaft.

As for the reliability of each type of bearing, they each have their flaws. Journals are mainly affected by dirty oil problems and are susceptible to axial load issues due to the thrust bearing setup. They are also more sensitive to low oil pressure such as at start and shutdown of the motor (which wouldn't really be an issue if you actually looked after the car). Ball bearings are affected if they are not cooled sufficiently and are pretty much a throw away item if the bearings let go.

I'm going to try and source some dyno sheets from these turbos in particular as well as a couple of GCG and Slide hi flows as well. Might take a little while though.
