Precision Turbochargers Ball Bearing Highflow - R32, R33, R34 & Vg30


Recommended Posts

Introduction:

As most of you know, I have been in touch with Precision Turbochargers in Sydney and have organised a Group Buy for SAU with very competitive prices compared to other well known companies as well as the highest quality in craftsmanship and service guaranteed.

Service:

Garrett Core Ball Bearing High-flow overhauls for all R32, R33, R34 and VG30 turbochargers. These guys can also high-flow WRX, 200SX, 180SX and many more. PM me with your info and ill get you a price.

Specifications:

The High-flow consists of a complete overhaul on your factory turbo including machining the compressor and turbine housings and then fitting a genuine Garrett Ball Bearing High-flow pack with steel wheels.

Power Ability:

R32 Precision Ball Bearing (450HP) High-flow - 235rw/kw

R33 Precision Ball Bearing (500HP) High-flow - 260rw/kw

R34 Precision Ball Bearing (550HP) High-flow - 285rw/kw

VG30 Precision Ball Bearing (550HP) High-flow - 285rw/kw

Dyno Proof:

Here is a dyno print of an R33 GTST with stock standard intenals using a Precision Turbocharger's Rb25 highflow with a VG30 exhaust housing. This car was tunned using a Haltech E11v2 along with other supporting mods and on Shell V-Racing Fuel. It made 280.9rw/kw @ 17.65 PSI. These turbos are made for a premium efficiency @ 25 psi therefore this turbo still has a lot to go!

Just got a call from Precision Turbo's and was told that if we get a list of 10 comfirmations, he will try and get them all done at a better price... so common guys if you are intrested in an exceptional value, then PM me!

Cheers

Yep i sure will as soon as i get them... hopfully early next week... you can also contact Tune House or V&E Rigoli regarding these highflows... they will tell you their personal oppinion..

Cheers

Pardon my interruption, but we need to clear up some facts.

1. 500 bhp is not 260 rwkw, well not in any Skyline I have seen. More like ~300 rwkw.

2. Similarly 550 bhp is ~340 rwkw.

That's a pretty big high flow using the standard turbine and compressor covers, albeit machined. I would be asking about compressor surge issues at that sort of power levels.

:laugh: cheers :laugh:

there are different ratings for at the engine,flywheel,at the wheels or the rear wheels.so i think someone that knows how to convert kilowatts at the real wheels to what it is at the engine would help. :laugh:

I do.

I did.

Based on over 30 Skylines that have been on our engine and chassis dynos

550 bhp / 1.34 = 410 kw

Drive train and roller losses in a typical R34GTT (mine for example) are around 60 - 70 kw

Hence 340 rwkw.

:laugh: Cheers :laugh:

I have been advised that there is a 30% power loss through the drive train... therefore 500hp = 372.85kw - 30% = 260.99rw/kw... please correct me if i am mistaken...

Cheers

I have had a few beers. Will this help make my car sound more like a jet taking off. Will this also help my car take off liek a jet? I am looking for a big mid range punch rather than top end (3500 + RPM for full boost is very nice, lower is much better) I want a responce/torque monster rather than a drag car. I am swaying towards a 25/30, 28/35 - although a bolt on sounds very nice as it makes everything look legal! What the general consensus? As per my sig i have a S2 33 gtst

Thankyou.

That is all :laugh: dont call me before 12 tomorrow :)

This highflow will give you a big HP increast through out yout rev range and being ball bearing, it will spool faster then journal and bush bearing highflows... i also got a S2 R33 and am going to get one of these highflows done.. If you want to be part of the group buy, PM me and ill add your name to the confirmation list.

Cheers

Just would like to clear up any misconception about these highflows. Precision Turbochargers use a genuine Garrett ball bearing high flow pack which Garrett themself rate at 500HP. Just call any of those performance workshops i listed and ask them, i did and they stated those power figures.

Hi Sarkis,

Will be wanting to upgrade my turbo soon as the standard one in my car is becoming the limiting factor.

The only problem is(and im not meaning to change anyones minds about these turbos) is paying $1550 for a BB high flow producing 260rwkw worth it compared to paying $1040 for a journal high flow producing the same power? There is also the option of buying aftermarket turbos for $1550 producing alot more power.

I guess there also the fact that these turbos dont need modifying to fit as most aftermarket ones do.

Is the faster spooling from a BB high flow significantly faster than a journal high flow?

Please dont take me as being a party pooper.Im just gathering as much info as i can like everyone else.

As they say a smart choice will be an informed one.

CHEERS

Dave

You are very very sorely mistaken. Here's the theory:

Car A makes 100hp at the engine and 50hp at the wheels - (a 50% loss in your terms) It therefore loses 50hp through means such as heat, noise, gearbox/clutch losses, tyres, drag and other drivetrain parasitic losses.

We then double the horsepower of Car A to 200hp at the engine. It now makes 150hp at the wheels losing the same amount of power through the same drivetrain. The gearbox, clutch, tyres, drag etc are all roughly the same. Using your terms, the car could now be said to be losing only 25% of its power through the drivetrain.

Just for kicks, lets increase the power output of Car A to 1000hp. Care to guess what percentage loss will now be measured at the back wheels? Not the 50% of the first example, nor the 25% of the second example.

The point is, any given drivetrain can't just automatically eat up a given percentage of engine horsepower. It's not possible. The last example wont lose 25, 30 or even 50 percent of it's power through the drivetrain used in the example. The facts of the matter are that in general, the most you can expect to lose through any auto or manual RB-engined combination is somewhere in the order of 55 - 80kW. This has been demonstrated many many times if you need confirmation. What's more, it's plain old common sense.

Hope this helps,

Adrian

NYTSKY - As proven by many members inc Sydneykid, BB turbos do spool up much faster then JB turbos. And for $1550 your getting a direct bolt on unlike other after market turbo's which need new water + oil lines, manifold, dump pipe and are a DEFECT! this high flow will give you the "stealth" look and also suprise all those who think ur car is stock... I am in the exact same boat as you and wanted the best option... but why pay $1000 for a JB high flow when its a down grade to the stock item? for an extra $550 your getting a BB item that will maximise your cars power output as well as last much longer then a JB turbo.

Adrian - Thanks for clearing it up! However im just going by what Tune house and Rigoli have advised me about these units... if a GCG 450hp unit is producing 260+ in some cars, then a Garrett 500HP unit should do just the same ifnot more....

Thanks to all those who have ordered via person... should get yours soon..

Regards,

Sarkis

well done dude :wave: i cant wait to get my slide highflow,aaron is a top bloke.i am looking at getting around 350hp at the wheels when i get more mods for the highflow like injectors,aftermarket ecu :mad:

    • Hey lads, reviving an old thread.  As an update, since the last time replied to this thread, ive done mostly suspension. Havent touched the motor except for maintenance. Though upon changing spark plugs, found out i had splitfires pre-installed! Updates: - Got me some stock airbox top cover and snorkel to fit onto the original intake. Should be free of defects - Bought a set of R34 GT-T brakes (not installed yet, going to rebuild + respray in champion blue + white 'Nissan' text) - Bought the last set of bilsteins from @Sydneykid and had them installed. Has been making some sounds on the rear but hopefully should be sorted out after this New Year break. - Regreased front caster rod bushings (poly bushes..) - Rear upper camber arms - Whiteline sway bars (BNF27Z 22mm + BNR11XXZ 24mm).  The rear sway bars are a bit short (ive read 50mm else where) but was still able to get them in.  Anyhows, I reckon suspension is sorted now. Maybe replace bushes (do have a set of front upper control arms from SK not installed yet) but should be okay for now. From now, I'm wanting to start working on the motor, drivetrain etc etc. Still debating on the order to go on and what to buy etc but: - ECU ( Haltech or Link ( Link states that it dont support A/T or AWD functions... Can anyone attest to this? ) - Highflow turbo ( ATR43ss2 ) - Intercooler ( Not decided yet, but cant find many good afoordable ones. Toshi says to opt for crossflow Japanese. Bit difficult this one, unless I get a returnflow Blitz from JJ? ) - Injectors ( Any recommendations ? I do have a nismo FPR ( Thanks SK ) ) - Seats - Tune by either Toshi or DVS To be fair, I did consider just keeping the stock turbo and nistuning it. Sat in a mates stock N, that had something like 200kw, and I reckon that felt more than enough. Maybe I should just go this route ahhaha. Too many choices.... Planning a trip down south, so wanting to just clean things up and make sure it gets to and from in one piece. Anything else specifically I should do before ? Cheers lads  
    • Must be for the car’s lucky charm 🤷🏽‍♂️ She runs fine, but it just seems to take about 1L less. Maybe I’ll have the oil sump dropped at some point to check if there is anything 
    • Hmmm interesting. Mine is the exact same and clearly the right one.  The mystery of the engine oil being full after 3.5-4L continues 
    • Yes I as well would like to find out where I could get some of the seat material with the red or blue small squares in it
