Niama-Reisser, LLC supplies a variety of turbocharger upgrade parts. They range from billet compressor impellers, to stainless steel turbine housings.
What makes our turbo performance upgrade parts so affordable, is the fact that you can upgrade them yourself, in your garage, following our specific installation instructions and using ordinary hand-tools found at Sears of Lowe's.
We have billet compressor impeller upgrades for Garrett GTX 2860R, GTX 3071R, GTX 3076R, GT 4202R & Holset HX82 and Borg Warner 478.
We have ceramic ball bearing cartridge upgrade / replacement kits for the NON-Serviceable Garrett GTX 3071R, GTX 3076R & GT4202R turbochargers.
In addition to OEM turbocharge upgrades, we also carry compressor impeller upgrades for "Off-Brand" Turbochargers mostly used in Ford Mustang, Corvette and Chevrolet LS turbo kits.
Our 84 and 86 mm Billet Compressor Impellers are intended for aftermarket, as well as our NR Brand X1 Turbocharger.
These impellers are optimized in Blade Geometry, Inducer Diameter, Hub Cross-Section, Mass, Blade Count/Pattern, & Tip Height.

We are coming out with NR Drop-In Billet compressor impellers for a variety of engines and models. To insure that every impeller fits perfectly, the OEM turbine shaft, diffusor and compressor cover housing are scanned using white light technology.
What sets us apart from the competition is that we design each and every impeller for a specific application or turbo.
Most of our competitors don't model compressor impellers from scratch. They are very limited in what they can do. For instance, most companies in the industry don't fully reverse engineer the compressor impeller. They merely scan one blade (or two), the hub bottom contour and compressor cover contour.
From there, they morph or scale that single blade, or in the case of inducer exducer blades, the two blades, to fit a larger or smaller compressor cover. Some just merely extend the same blade in the tip region, as this illustration shows.
The GTX 3582 and GTX 3076 Garrett compressor impellers have been completely reverse engineered by us. In case of STOCK OEM and AFTERMARKET IMPELLERS, you can easily spot the AFTERMARKET IMPELLERS. They look almost identical in design (general shape of the blade, etc.), yet the blades are extended in the tip area (see dotted red circle). These modifications are fairly easy in comparison to 100% custom, optimized geometries.
The GTX 3582 and GTX 3076 Garrett compressor impellers have been completely reverse engineered by us. We actually reverse engineered a solid model of each (not just surfaces), which included the balancing marks on the GTX 3076 compressor impeller (see dotted area).
The shown ceramic ball bearing cartridge comes as a 6 piece assembly. The cartridge fits a Garrett GT4202R CHRA. It is designed for HEAVY DUTY applications.
Requires boring out CHRA housing.
Instructions come included.

Replacing your Garrett GT style ceramic ball bearing cartridges is impossible, since Garrett doesn't offer any parts. However, we have a variety of high speed ceramic ball bearing cartridge kits that enable you to rebuild GT style turbochargers.
You can see the spring between the outer most ceramic bearing to the right and the pressure plate pushing against the inner most bearing to the left (bearing not shown). If this type of CHEAP turbo boosts beyond the stock gasoline max pressures of 8-16 psi, the spring will allow for movement of the Turbine shaft--the axial end-play of the shaft is affected. This in turn at loading and surging of the compressor, can cause the compressor impeller to touch the compressor cover or the turbine respectively the turbine housing.
Lastly, you cannot buy good quality ceramic ball bearings for less than $ 200.00 / piece (size dependent). Ceramic ball bearings costing only $ 80.00/piece is a failure to happen.
Why do CHEAP aftermarket turbo manufacturers use springs?
Because they cannot hold tolerances at their price point and with their CNC machinery and staff.
For that reason GARRETT does not use springs! See below in red dotted circle (inner races shown only!).
CAT and Cummins unparalleled power by using the HX 82 Holset turbocharger as an atmospheric turbo in conjunction with our NR Optimizer HX82 Billet compressor impeller.
This dual stage turbo system in line with a Borg Warner 478 manifold turbo, reduces manifold temperatures by over 150 degrees and increases peak boost by 15 PSI.
The overall system increases fuel economy, performance, engine life (reduced heat under full load), as well as CLUTCH and transmission wear, due to drivers not having to downshift as much.
The picture above shows a dual charge system installed on a C15 CAT truck engine.
The dotted circle indicates the atmospheric Holset HX82 turbo.
Our NR Optimizer HX82 Billet Compressor Impeller is ideally suited for large oil & gas generation and electrical power generators.
These extremely large 18 cylinder diesel engines, with their 78 liter displacement, are ideally suited for our drop-in billet compressor impeller.
By only changing the compressor impeller, in all six atmospheric turbochargers, a fuel economy gain of approximately 5-8% is achieved.
NIAMA-REISSER, LLC is your one-stop solution to all your forced air induction needs. As it stands, we have designed over 100 compressor impellers, ranging in inducer diameter sizes from 28 mm to over 380 mm across.
Having performed numerous CFD Analysis for small and large frame turbochargers, we have the knowledge, CAD and CAE Software along with Beowulf cluster servers to calculate transient and static performance graphs of any given turbocharger application. Slow or Fast rotor speeds, High Boost or Low Boost applications, it does not make a difference to us.
The least expensive solution is for you to vest your trust in our ability and track record of utilizing our unique turbocharger "know-how' in designing out-of-the-box proprietary geometries, that have benchmark setting performance levels and are extremely hard to duplicate, by your competition.
In addition to all of our design and manufacturing turbocharger services, we also offer NIAMA-REISSER NR Optimizer off-the- shelf performance turbocharger parts and complete turbochargers. Whether you own a Porsche 911, Ford Mustang, Chevrolet Camaro, or large tractor pulling diesel engines, we got your turbocharger needs covered.
