Anyone Have A Rb25 Highflow From "sliding Performance"?

[Slide]

hey i know i sound like a newb asking this, which i am but what is the difference between ball bearing and bush bearing? any spooling differences? which one has longer life?

slide: money is starting to build up... one more week i hope and i will be able to try out this thing.

stan: hey man, im guessing your hitting boostcut? maybe? dunno? hehhee

The second paragraph tells the truth

http://www.reliabilitydirect.com/appnotes/jb.html

And here is ball bearing.

And here is nearly every garrett GT turbo available in journal.

As usual it’s not what they tell you that’s important, it’s what they don’t tell you. Journal bearings require consistent oil pressure. In a turbo (spinning at 100,000 rpm with an 800 degree exhaust off one end) any decrease in the oil pressure/flow will lead to instantaneous failure. This is not the case with ball bearing turbos, they can tolerate periods of zero oil pressure. Any small contamination in the oil has a similar result, as does overheating the oil.

Many plain bearing turbos are not water cooled, so the oil has to perform both the lubrication and the cooling tasks. This transfers excessive heat into the oil system.

Nissan didn’t spend $Millions with Garret developing ball bearing water cooled turbos for no reason. Personally, I see no sanity in downgrading from the standard, ball bearing, water cooled turbo to a plain bearing one.

I have had one of Aarons larger t3/t4 highflows for 8 months and recently after putting a hole in my number one cylinder he checked the turbo out stipped the cartridge and there was no wear what so ever i run it at a constant 17 psi of boost and it the most aggressive car ive ever been in.

I drive it to the death every time i get in it and with this turbo you just have to its awesome

They are water and oil cooled and used the stock lines slightly modified as stated.

I have never had any problems and he answered every question truthfully and did not hold anything back.

i had 220rwkw with a mines ecu and i cant wait to get a power fc and get the last bit out of it.

I also know that it has a return 1 year warranty so if it stuffs up within a year i can return it and have it rebuilt and if it does it again i can return it again.

Im also familiar with the added costs of ball bearing turbo's and they cost heaps to repair

Hope this helps with peoples descission as it definately hasnt stopped me from loving the way my car goes.

I had one of Aarons highflow turbos in my car for a while and had no problem with it at all and went like the clappers. If you want a cheap upgrade that will put your car basically into the 12's (depends on the car)this is what you want. But I wanted to go fast than that so stupid me went and spent BIG dollars on up grades to the motor and bought T04Z off sliding Performance to go with it. I wish I just stayed with the high flow turbo because of how cheap it was to upgrade and how well it went

[Slide]

Thanks guys

The journal bearing system does get hot under the collar thats why we have increased the water throughput by making the banjo bolts larger for the water lines (these bolts come with the turbo along with the required copper washers) We also bore the oil banjo bolt aswell and have it a requirement that the oil lines be bored to provide sufficient cooling and bearing lubrication.

And if the engine was to lose oil preasure it would not be just the turbo that becomes a little depressed and close to suicide

This scenario can easily be avoided by regular maintanence and inspections.

This has been tested and is fully supported by us under a 1 year return to base warranty located on the Gold Coast.

In the event that there is a warranty return we provide an additional 1 year support for the returned turbo to keep satisfaction at its maximum

Aaron - can you tell me these turbo's rating at the said 18-22 psi..

450? 500hp?

[Slide]

The larger t3 with t4 size exhaust housing is rated to 250rwkw and power is made up until 19 psi max which is about 330 rwhp

This can be achieved with the right supporting mods.

The straight t3 highflow uses the complete t3 turbo and the compressor and exhaust housings are bored out to fit larger internals.

This turbo is more suited to an rb20 as a good responsive little upgrade rated at 220rwkw or around 295 hp with the right supporting mods and power is made up until 17 psi max.

This is the maximum amount of power you can get out of these turbos as the size restricts airflow.

We carry larger Turbos which use garrett housings and garrett internals and pretty much any power turbo can be sourced be it internally gated or externally.

We also do 300zx turbos, silvias, soarers supras etc all of these turbos can be highflowed some even retain the ball bearing cartriges.

If you would like any more information please feel free to pm me or email me.

Cheers Aaron

Edit: we are at zero supply of used wastegate actuators for these turbos at the moment so alternative sources need to be used for the purchase of a 2nd hand one.

If we are unable to supply one, the turbo will be $60 cheaper

The wastegate actuator required is just a standard t3 that comes with r32 r33 and r34 turbos

The shaft can be modified to have more resistance. for more boost and less work for boost controllers.

even better, I'll come visit you when I move up to Brissy.

Sounds like a good cheep alternitive to the GCG highflow. What is the cost of the 250rwkw version Slide. Does anyone else have this turbo installed and a dyno graph to show us will be very interesting to compare it to the gcg highflows.

cheers

The cost is $890 delivered

The slightly larger version was made for Stan with a slightly even larger exhaust housing and turbine as his is a triptronic auto and as they are never really "off boost" when on the accelerator more exhaust flow was the go

These are $950 delivered

Stan(Satanic) has one of the larger (hybrid) ones however Chris (SkylineSII) and Jarrad (sirskyline) had the normal t3/t4.

Constantly_incognito (Ash) From these forums also has one of the t3/t4's

Im not sure of who else has though as they are mainly purchased off the website so guys if your reading let us know

The flow testing results that come from these turbo's corrospond with a certain code which is explained in the flow testing manual which gives us the data to find the limits of the turbo.

This is Stan's (Satanic)'s Dyno Graph with power made from a cat back exhaust 11 psi of boost and an Safc II.

As explained on his website his factory computer couldnt handle the airflow so he was hitting boost fuel cut after 11 psi which is an issue he is having resolved at the moment.

His Build process and information can be seen on his website. http://satan.p5.org.uk/

Dyno Sheet

I will work on trying to find more dyno graph's but im sure Chris would be more than happy to post his as he reported 223 rwkw made at the P.I.T.S dyno on the Gold Coast with the following mods.

Mines tuned ecu, front mount intercooler, pod filter, and 3.5" straight through exhaust are the only mods.

not even fuel pump however he was told he needed a power fc, fuel pump and injectors as everything was maxing out on a series 2 R33.

[paulr33]

im with sydneykid

sure its cheap but i dont think its worth it

performance upgrades are never cheap

[Slide]

Hi Paul

These are not cheaply manufactured Chinese turbos and we stand by them with a strong warranty.

Our goal is to be able to provide good performance at a very affordable rate when it comes to turbos and ball bearing highflows are also built by us daily to compete with the GCG turbo's with minimal difference between the two.

We strongly believe though if you were going to spend that sort of money on a turbo you may aswell go big and buy a larger Garrett or equivalent turbo as the price difference is minimal.

Aaron

[paulr33]

hey aaron

i am not saying they are cheap chinese turbo's

no one was aware nor does the supplier make aware the main difference of journal bearing in real life until gary explained it. so i guess this is where the main cost comes from. i am sure its more expensive to balance a ballbearing centre vs a journal bearing centre.

[Slide]

Thats correct

However we do spend alot more time on them so that there is very minimal movement in the sleve so that the oil fill is quick and stays in there.

They are a very good modification to put you into the 12 second 1/4 mile times

Aaron

[satanic]

Thanks for letting out the secret of my turbo Aaron HeeHee they only know it's different, they don't know "how" different

Anyways, I'm more than satisfied with the turbo and until I get bored of it (which is when I manage to unlock the ECU) I won't be changing!

And yeah, respect that bishes - who says you need a full exhaust to get 200rwkw Expensive way of doing it, but it's doable

NOTE: The banjo bolts are very very important - I learnt this during my installation! New bolts from Enzed cost $35 each.

Thanks slide

Am I reading this correctly the 250rwkw version is $890? Does the $950 version make more than 250rwkw due to the larger exhaust houing? Im interested to see the dyno results. If these turbos make the power and spool similar to the GCG ones I think they are well worth the money.

cheers

[satanic]

Aaron, I hope my turbo remains unique and special!

[TTT]

Paul - you are right and wrong.

not everyone can afford big name turbo's from HKS or trust.

not everyone wants power and numbers like BUSTER.

not everyone has the knowledge and knowhow that SK has or the tools to do all the work.

not every car has ball bearing turbo's.

just to name a few cars that do without ball bearing turbo's and survive..

VL turbo. 80's car and still running.. some even on stock turbo.. and with no bov..

Liberty RS turbo's... I've seen cars with over 300,000kms on it on stock engine and stock turbo.

The cheapest I've seen ball bearing hi flow from GCG is $1700 for the 450 hp version.

you can buy 2 of these for that price.

he offers a 1 year warranty.

he is straight forward with what he is selling and what to expect.

as much as I'd like to play with the big boys and spend big money on my car habbit, I (and I'm sure a shit load of people on these forums) can't afford to do that.

just something to think about before jumping on the BB wagon.

im with sydneykid

sure its cheap but i dont think its worth it

performance upgrades are never cheap

I think that is completely wrong.

you can have cheap upgrades.

an rb20 with one of these turbo's, $28 boost controller, rechip, walbro pump, $30 air filter and $600 xforce exhaust system can be just as good and probably within 10-15rwkw of the same car using top of the line ecu, pump, exhaust, turbo, blah blah blah..

You might be in a different financial boat then me, but I just think that you need to consider the rest of the peeps

[satanic]

I think personal preference / expecatations would have a lot to do with the BB v Bush decision (not to mention GTST's point on wallet size)

But seriously for under $1k where can you go wrong

[Tangles]

What about lifespan??

How long would this $890-950 turbo last (kms?) when say left at 1bar boost on say a car like Stans? Id imagine a BB hiflow turbo would be good for 80000kms+, how about your model Slide?
