Pavel’s Racing Engines is extremely excited to offer this product to the public. We have been testing these compressor wheels in various turbocharger models and engine combinations. Every time this product proves to make more power than its cast aluminum counterpart!
We tested these compressor wheels on the dyno with a consistent 25-30WHP gain at same boost level as stock cast wheel. Torque increase was moderate as well in the mid-range engine RPM. All testing performed on same vehicles within a narrow installation time window to reduce erroneous data.
This particular post focuses on billet compressor wheels for IHI VF-series turbocharger found on JDM, USDM, and UKDM Subaru Impreza WRX and STI vehicles.
COMPATIBLE TURBOCHARGERS:
- VF30 (JDM V5 STI)
- VF34 (ball bearing turbo)
- VF37 (twin scroll turbo, JDM V7/8 STI)
- VF39 (USDM 04-06 STI)
- VF43 (USDM 07 STI)
- VF48 (USDM 08-15 STI)
- VF52 (USDM 09-14 WRX, upgrade for 2008 WRX and 05-09 Legacy GT, originally VF40 or VF46)
PRE BILLET WHEEL FEATURES AND ADVANTAGE:
- 11 blade design: Conventional design is 6 tall and 6 short blades. Garrett has proven higher flow potential of the 11 blade design and it has been adopted to this compressor wheel for IHI application.
- Extended tip design: Conventional compressor wheel tips perpendicular to the exducer diameter. Extended tip technology originally developed as “cheater” compressor wheels for racing use. Standard exducer diameter is 60mm, while extended tip compressor wheels had 63mm exducer diameter for total blade area increase of 6%. This of it like a larger area of an airplane wing allowing for increased lift. The larger surface area allows for increased flow volume at same turbo speed.
- Slim blade design: Performance feature designed to increase air flow. Slim blades have a smaller cross-section allowing more area between blades for air. Flow is increased at same turbo speed. Thinner blades also weigh less for reduced moment of inertia and faster spool.
- Slim hub design: Another feature designed to increase air flow. Slim hub increased air volume with each rotation. Flow is increased at same turbo shaft speed. Smaller cross-section hub weighs less for a reduced moment of inertia and faster spool.
- Material selection: Conventional compressor wheels made by casting aluminum alloy. PRE compressor wheels machined from billet aluminum alloy block. Billet blocks are forged. This compacting of molecules increases material density and strength. Increased strength of billet material allows for reduced blade and hub cross-section and weight reduction without increasing internal stresses.
- Balancing: PRE compressor wheels inspected and computer balanced to less than 0.5g-cm^2. This does not mean compressor wheel should be swapped as-is. Stack-up dis-balance is always a factor and compressor wheel balancing should always be performed by a professional using entire rotating assembly.
Extended tip technology comparison: black dotted line is conventional design and the red dotted line is our billet wheel design.
Recently we dyno tested a couple of Subaru cars and recorded data logs. To keep this an apples-to-apples comparison we tried keeping the variable to a minimum. This comparison shows a 42WHP gain at 1.5psi LESS boost than stock turbo.
Car 1 (Red Line) 2007 Subaru Impreza STI
- Stage 1 rebuilt short block with 8.8 compression forged pistons
- stock rebuilt cylinder heads
- stock fuel injectors (maxed out at 21.5psi)
- stock fuel pump
- larger intercooler
- Perrin inlet pipe
- OEM rebuild VF48 turbo with cast compressor wheel (6/6 blade design)
- ECU tuned by 555 Motorsports
Cars 2 (Blue Line) 2010 Subaru Impreza WRX sedan, 5-speed manual transmission
- Stage 1 rebuilt short block with 8.6 compression Wiseco forged pistons
- stock rebuild cylinder heads
- stock fuel injectors (maxed out at 19psi due to higher flowing compressor wheel)
- stock fuel pump
- larger intercooler
- Perrin inlet pipe
- OEM VF52 turbo rebuilt with PRE billet compressor wheel (11 blade design) VF52 same size turbo as VF48. The only difference is compressor housing outlet orientation. All other internal parts same.
- ECU tuned by 555 Motorsports

Looking into your 11 blade billet compressor wheel for the ihi turbo.
Is there any modification needed to make the wheel fit into a vf48? Meaning it will bolt up into a stock unmodified compressor housing? Aside from having it balanced.
I just rebuilt this unit and wanted to upgrade wheels
Thanks
Hi Aaron,
This compressor wheel is direct replacement into stock housing. No machining required.
Thank for the interest,
PRE
Hi Lads, is there any possibility this wheel will fit the VF42 on my S204? It currently makes 280awhp with max of 21psi
Hello Joshua,
Check your email for additional information request.
Thank you
how difficult is it to replace the compressor wheel alone? you do not sell a kit with the wheel do you? with CHRA?
Hello David,
We do not recommend just a compressor wheel replacement on its own due to balancing concerns. Turbochargers operate at over 100,000RPM and any dis-balance will cause premature bearing wear and eventual turbo failure. We always recommend rotating assembly balancing. If you have a good working turbo we offer turbo service and billet wheel upgrade for $400. Turbo service includes replacement off all oil seals, bearings, and turbo balancing.
What supporting mods would you recommend on this? Or will I be able to install and go? Also if I could find where to order.
Hello Max,
Thank you for the inquiry. At very least you will need 05+ STI pink injectors or 08+ WRX blue injectors or anything in the 550cc range; additionally a Walbro 255 fuel pump and ECU retune will be required. 550cc injectors will support about 19psi before duty cycle becomes unsafe. These billet compressor wheel work efficiently up to 23psi and we typically install Injector Dynamics 1000cc injectors for additional fuel demand. We do not recommend modified OEM injectors, ie Deatschwerks/WitchHunter/FiveO, due to poor atomization and idle/low speed misfires. We can supply you all necessary parts for this project. Please check your email from us for additional information and we can discuss your project.

im opensource tuned, will i need to get another tune?
Do you ship up to canada?
Hello Nik,
We ship world-wide. Check your email for additional details from us.
Thank you!
Hello Jesse,
These compressor wheels flow considerably more air than stock and will require an ECU retune. Without an ECU retune your car will run dangerously lean. If you need additional help don’t hesitate to contact us via email or phone.

Hi. I’m interested in the bullet wheel for a vf48. Please send me details on how to order from South Africa.
Please check your email for order instructions. Thank you for the interest.
Hey there, I’m interested in this billet compressor wheel for a vf52. How much does it cost? I am also interested in your turbo rebuild/upgrade service. Thanks,
Adam
Hello Adam,
Thank you for the interest. Billet compressor wheel costs $105 shipped. Standard rebuild service for IHI turbos starts at $300.
I have an 05 Legacy GT. It has a bunch of miles on it, but is in good shape except for some oil consumption from the turbo. I want to replace the turbo instead of the car and need some advice. I am a mechanic and have been working on gas and diesel engines (NA as well as FI) for many years, so I am able to hold an intelligent conversation on the topic but I am familiar only with stock stuff and am smart enough to know I need help. My Subaru is my daily driver and I don’t want to do anything that would compromise it’s near perfect reliability or turn it into a fuel hog, but being as I will be replacing the turbo, is there an option to “bolt on” some more power during the repair I am doing anyhow? I am happy with the power the car makes and it is quicker than most stuff on the road as is, so big money is a deal breaker when a stock turbo would fix my problem and please me just fine. Can you recommend a product that meets the narrow window I have given? Thanks!
Hello Mike,
Thank you for the inquiry. Please read below information. I broke it down in order it should be done and general importance.
Before removing turbo for service I always advice performing a compression and leak-down tests on the engine; preferably hot. Typical compression numbers are 145-155psi. Anything below 132psi is deemed a failure by Subaru OEM standard and dealer would advice for short block replacement. Leak-down numbers on a healthy engine will be less than 10%. Any more usually means exhaust valves have worn, requiring valve regrinding and recutting valve seats.
If your engine passes both these tests proceed to inspecting and removing banjo bolt filters in the AVCS oil lines. You can skip this step if it was already performed. This is a critical step. If you have any questions DO NOT hesitate to ask.
Inspect your tom-mount intercooler. It is made of aluminum core with plastic end tanks that are crimped on. Make sure crimps are not pulling apart. This can occur with age. I have replaced it several times on person car and multiple times on customer cars. Good used, low mileage OEM-replacement intercoolers can be found very reasonably priced.
Your car has an IHI VF40 turbocharger. It is possible to gain more power without sacrificing drivability or gas mileage just by recalibrating engine ECU. Boost limit of VF40 turbo is about 19psi. Boost limit of your stock intercooler is about 16psi. Anything past that will cause the crimps to pull apart, leak boost pressure, and cause drivability problems. Power capability of VF40 turbo is about 240whp.
IHI VF52 turbo off the 2009-2014 Impreza WRX is a direct upgrade for our VF40. It will bolt right up and essentially a larger STI-size turbo with correct compressor housing orientation for your Legacy GT. This turbo is capable of 22-23psi boost and power output of 300whp. As mentioned above, your stock intercooler can only handle 16psi. Another not, your stock fuel injectors run dangerous high on duty cycle at 22psi and I always advice to upgrade to bigger injectors if you intent to run more than 20psi boost.
IHI VF52 with billet compressor wheel upgrade is the next stepping stone. This turbo is based on the VF52 and uses our compressor wheel upgrade. Maximum power output for this turbo is 350-360whp at 23psi. This level of performance requires considerable upgrade to everything from fuel system to intercooler, exhaust, intake, and usually even the clutch.
Based on your needs I believe a stock rebuilt VF40 coupled with an ECU recalibration is the best option. I will send you an email with this same information so we can discuss a solution that best suits your needs.
Hi can you please email me payment details as I’m interested in the billet wheel for vf52
Hello Adam,
Please check your email for payment information. Billet compressor wheels are in stock and ready to ship.
Hi,
These wheels sound great. Have you got any data on upgrade performed on a VF34? I’ve got a VF34 and am trying to squeeze all the performance I can out of it.. With that kind of WHP gain in addition to e85 fuel, I’d be looking at approximately 250-270awkw theoretically.. A very tempting choice! Also purchase information to Australia would be appreciated.
Many thanks,
Hello Tyrone,
Currently, we have several billet wheel VF34 turbos finished and waiting to be tested on our shop car. VF34 and the journal bearing VF30/37/39/43/48/52 all have same size turbine and compressor impellers. The only difference is ball bearing versus journal bearing configuration. Peak power will be just about same and the main improvement is spool characteristics and midrange torque. So far highest rating we measured is 360whp/370lb-ft at 23psi on a bolt-on upgrade WRX. This is using 93 octane fuel. E85 fuel will allow closer to 400whp and hopefully as much torque. Please check your email for a message from us for purchase information.
Thank you,

VERY INTERESTED IN PURCHASING UPGRADED WHEEL FOR MY VF30 DO YOU ALSO SELL REBUILD KITS?
ALSO CURIOUS IF THESE NUMBERS FOR PRE UPGRADE TURBOS ARE ON A STOCK MAP OR IF THEY ARE ALSO ON A TUNE FROM 555
Hello Tyler,
Billet compressor wheels are in stock and ready to ship. We do not sell rebuild kit separately. We can rebuild your turbocharger and upgrade it to the billet compressor wheel.
Hello Tyler,
All billet compressor wheel testing performed at higher than stock boost levels thus requiring an ECU recalibration. Due to increased air flow provided by billet compressor wheel and significant change in air-fuel ratio an ECU recalibration is required when upgrading to billet compressor wheel. All of our ECU recalibration services are performed by 555 Motorsports.
how do I purchase this wheel?
Thank you for the interest, Jeremy. Check your email for pricing and order details. The cost of billet compressor wheel is $105 and includes domestic shipping. Thank you for the inquiry.
I have a Vf30 on my V7 STI that I would like to squeeze more power out of and quicken up the spool time. What would it cost for an overhaul and could it be upgraded to ball bearing? What sort of HP numbers would it be able to produce after a tune?
Thanks.
Thank you for the inquiry.
Turbo spool time is not greatly improved by the billet compressor wheel. The turbo comes to full boost at about the same RPM as stock, but because of increased air flow, there is a considerable increase in midrange torque and power. You won’t see ball-bearing-like response because, after all, it is still a journal bearing turbo.
We do not offer ball bearing conversions.
We have upgraded several VF30 turbos in the past with our billet compressor wheels. Two cars were dyno tuned and customers reported back with results. One car was tested on a Dynojet and the other car on a Mustang dyno. Mustang dyno car test showed 300whp at 22psi. Dynojet test showed 332whp at same 22psi. Both cars had very basic bolt-on setups using OEM turbo, TMIC, 93 octane fuel, Walbro 255L fuel pump, and ID1000 fuel injectors. If you have stock injectors, that are in the 500cc range, they are only capable of supporting 18-19psi of boost with the billet wheel. Increased boost levels will require larger injectors. We recommend ID1000’s from Injector Dynamics. We can supply you injectors along with the turbo service.
Standard turbo rebuild cost is $300 and billet compressor wheel upgrade costs additional $100. Insured return shipping in the continental USA typically costs $25-30 depending on your location.

Hello
I own 2012 mercedes c250 coupe
Original engine 1.8turbo uses ihi rhf4 turbo
Is it possible to upgrade ihi turbo ? Or should i get rhf5 turbo ?
And if its possible to hypred the turbo how much more power can it produce ? And how much does it cost ?
Could you pls send me email about the details and is iif i send you the turbo can you upgrade it ?
Thanks
Thank you for the inquiry. We never upgraded a C250 turbocharger but the rebuild parts are available and we can either find or make necessary parts and a billet compressor wheel. You will have to supply a good used core for disassembly, inspection, and measuring. Some turbos can be upgraded to bigger turbines and compressor wheels while other turbos have limited space inside the housing casting. Until the turbo is here to be measured, it is hard to say what exactly can be done. A typical cost of a turbo rebuild and upgrade to a bigger compressor wheel is $700. Upgrading to a bigger turbine and machining the manifold can cost $200-300. It is hard to estimate but considering fixtures have to made, or modified, to machine the complex housing castings, your range is about $1000. Please check your email for a reply from us and discuss additional details.
I would like to contact you directly via email with questions about upgrading the vf52 on my 2012 wrx. Any chance I can buy a fully balanced CHRA with the upgraded wheel rather than send the whole turbo in. Looking to minimize down time. Plus other questions.
Thanks
Hello Tom,
We have the billet comp wheels in stock as well as rebuilt cartridges. Current rebuild time for a VF52 turbo is 2-3 business days.
Hey, I have a blown VF22 with blown bearing lying around. Am wondering if anything can be done to make it work again, and cost please?
Alternatively, can i upgrade a twinscroll vf42’s or vf36’s wheel? I wonder if the wheels are same as the single scroll version.
Thank you in advance.
I have one of these installed on my daily VF34 for over a year now. I can say i haven’ even tried to max this turbo, but so far it’s a nice gain over stock VF34.
I installed this turbo with no balancing, but this is what I did:
I marked the nut location to the shaft and ensured the turbo shaft nut was back in the same spot when retorqued.
When retorquing, ensure you only torque to 12 inch lb (NOT FOOT LB, inch)
You will need a special tool for that. Over torque and u may bend the shaft.
Hello,
I am looking for a quote for the following services for a vf34 going on a 2005
forester xt 5 speed: rebuild, port and polish and billet wheel upgrade. I was
thinking either an 11 bladed extended tip It will never
see the track, just going to be a daily driver so I’m looking at low and midrange with a fast spool. It is getting the following mods : Mishimoto top mount,full 3″ catted turbo back, gasket matched STI exhaust manifolds , cross pipe and uppipe, dw255lph fuel pump and a cobb accessport and protune. This is about as far as my build
will go. Also going from the TD04 to a vf34 will I need to change oil lines now that it will be a ball bearing turbo? Anything else needed?
Thank you for your help,

Hello Recently dropped in a newly rebuilt Ej255 on my 08 Wrx I have a custom tune for a vf52 swap I did in the past my turbo looks a little tired and it’s giving me issues. The new engine Has forged pistons and fuel has slight upgrades. Now for the question. I want to rebuild turbo.. but also upgrade. Will I need a retune. I’m Ok with what I have but would love a possible increase with your Billet setup. I will most likely be doing the Rebuild my self . Can you guys help me with all parts needed? Thanks for your time.
The billet compressor wheel requires a retune for optimum results and the highest increase in horsepower. Please check your email for additional information.
Hi
Is it possible to use the vf30 compressor wheel and housing on a vf23?
Your VF23 turbo is ball bearing. You will need a VF30 compressor housing, our billet wheel is compatible with the VF30 turbo, and a new compressor housing seal plate.
