Upgraded mu TD04HLA-19T twin scroll with this baby on my Forester XT hybrid build with twin scroll headers. Less restrictions up top, same quick spooling turbo. All parts fitted nice, only the oil return pipe I used the one from the old turbo because I needed a longer one to fit well over the hose.
Install with wrong size blade how can you install a car with blades scratching the turbo walls?.please contact me
Why a Wheel Can Touch the Housing (Dry vs. Running)
If you are rotating a new or unprimed turbocharger by hand on the bench and feel the blade tips lightly contact the housing contour, it does not automatically mean the wheel is the wrong size or defective: (All turbos done balance test before shipping)
1. Hydrodynamic Journal Bearings: Performance turbochargers use floating journal bearing systems that require running clearances. Under normal engine operation, pressurized engine oil creates a hydrodynamic oil film (oil wedge). This film lifts and centers the rotating shaft assembly with zero metal-to-metal contact. Without oil pressure (dry on the bench), tilting the shaft with your finger will allow the blades to touch the housing.
2. Dynamic Balancing: Factory assemblies are dynamically multi-plane balanced to high RPM tolerances. Once up to operating speed and supported by oil pressure and dynamic load, the shaft centers within sub-micron design limits.
3. Aerodynamic Stabilization: As the compressor generates boost pressure, aerodynamic forces across the wheel and the thrust system stabilize the rotor assembly along its rotational axis.
Solution:
Pour fresh engine oil directly into the CHRA oil inlet port. Slowly rotate the compressor wheel by hand while keeping the shaft level so oil fills the bearing clearances.
Verification: Gently spin the compressor wheel; the shaft should spin smoothly without catching or binding once lubricated.

Fits great on a subaru 02 wrx with iag oil pan. The quality looks good aswell. I used grimmspeed gaskets.
The whole process was very easy very fast delivery and great product. Great company
Purchased as a replacement for my discontinued turbo. Installation was easy and the product was as described. Would 100% buy from kinugawa again.
so good it snapped the crank 👌
Great product, 24/7 support, fast delivery!
Higly reccomended
I ordered the turbo with a spring rated for 1 bar, but it doesn't go past 0.5. I need you to send me the correct spring—the one rated for 1 bar.
Hi Premaq, thank you for your feedback. Please check the connections for leaks and review the preload process as you requested. We'll get back to you once we've completed the inspection and addressed the spring issue. Thanks for your patience!

Fast delivery. Product works well 👌
Installed on my FL5 paired with PRL HVI and Titanium inlet pipe. Yellow spring is perfect, no codes and you get that low RPM flutter. Sounds amazing!
I received my order on time and packing is really good
Turbo works and the quality looks acceptable, however the product is NOT truly plug-and-play for Mazda CX-7 MZR DISI as advertised.
Installation required significant modifications:
oil return line did not fit properly,
custom machining/fabrication was needed,
some supplied fittings/bolts did not match correctly,
additional drilling/adaptation was required during installation.
My workshop spent much more time than expected adapting the turbo to fit correctly.
If you buy this turbo, be prepared for custom work and additional installation costs.
In my opinion this should be clearly mentioned in the product description instead of presenting it as direct-fit replacement for CX-7.
juste quelque modification serait bien pour un montage plus propre sur le retour huile et alimentation d'eau
J'ai bien reçu la roue de compresseur. Il est magnifique. Il a été monté sur mon turbo mais pas encore testé.
Je pense que je vais être très satisfait.
I love the fact that its’s the only bypass valve that comes with optional springs, no one else offers this. Installation is the same as the other bypass valves, took me less than 1hr to install. Great quality and love the sound it produces. I’m currently using the Medium spring rated at 15-25lbs.
Didn't fit properly. Asked customer support and they sent out new ones to spec.
The turbo is top notch. Billet wheel, perfect fitment! Looks wicked. Will update when I get the car running, but fit and finish at this point is top notch. 1987 Conquest Tsi
This thing works great and sounds amazing
Gives very good spool with ar .49 turbine housing but it restricts the engine faster than I hoped for. At the dyno we got 380 hp with ej207 also had some other minor restrictions but the main reason was the housing being too restrictive. Trying to replace with 0,73ar housing for better results.
this upgraded turbo unleashed hell on my jukes 1.6l engine great buy direct fit. thanks for helping me out with my turbo needs
Excellent
Very good and durable turbo!!! The wastegate is a bit wide and the Mazda MPS 3-6 heater pipe is also worn because of this, the spring in it is difficult to replace. The Mamba is a little better. The oil line in the kit cannot be used because the screw is not suitable for it. The delivery is delayed for more than a week for the second time. Delivery to Hungary is 200 dollars, but to Slovakia it is free within 10 km.
Good quality, works like a charm.
Turbo arrived at my address in Japan super quick. Loved the fact that I didn’t have to pay any import fees. Turbo is well made and is working better than expected. Fast spool with 264 Cams and 800cc injectors. Thanks
