Performance Upgrade Turbochargers Catalog: GTX, G-Series and Bolt-On Turbo Solutions

Performance upgrade turbochargers are one of the most important product categories in the modern tuning and motorsport aftermarket. For workshops, turbo rebuilders, importers, wholesalers and performance parts distributors, the right turbocharger range can serve different customer needs: street performance, track builds, high-power engine projects and direct-fit upgrade solutions.

Trimpexparts offers a broad catalog of performance upgrade turbochargers, including universal GTX series turbochargers, G-Series and G(GT) universal turbos, and bolt-on turbo upgrades for EA888, GM LTG and related applications. The product range covers different compressor wheel sizes, turbine wheel sizes, turbine housing options, wastegate configurations, flange types, HP ranges and engine displacement targets.

This makes the catalog suitable for B2B buyers who need both universal performance turbochargers and application-specific bolt-on upgrade turbos.

What This Performance Turbo Catalog Includes

The catalog is divided into three main product groups:

  1. Universal GTX Series Turbochargers
    These models cover GT20, GT22, GT25, GT28, GT30 and GT35 frame turbochargers, with listed power ranges from smaller 140–230 HP applications up to 550–1000 HP high-performance builds.
  2. G-Series / G(GT) Universal Turbochargers
    This range includes popular upgrade models such as G25-550, G25-660, G30-660, G30-770, G30-900, G35-900 and G35-1050. Some models are available in standard and reverse rotation, with V-band, T25, T3 or T4 turbine inlet configurations.
  3. Bolt-On Upgrade Turbochargers
    This section focuses on direct-fit and application-specific performance upgrades, especially for EA888 Gen II / Gen III engines, Audi / VW transverse and longitudinal platforms, and GM LTG engine applications.

Universal GTX Turbochargers for Custom Performance Builds

The universal GTX turbocharger range is suitable for custom turbo kits, motorsport projects and performance workshops that build applications around specific compressor and turbine requirements.

The catalog starts with compact models such as GTX2052-38, GTX2056-42 and GTX2256-42, which are suitable for smaller displacement engines. It then expands into GT25 and GT28 models such as GTX2560R, GTX2860R, GTX2867R, GTX2871R and GTX2876R, which are common choices for 1.8L to 3.0L performance builds.

For higher-power applications, the catalog includes GT30 and GT35 models such as GT3071R, GTX3076R, GTX3582R and GTX3584R, covering listed ranges up to 1000 HP depending on the turbo configuration and engine setup.

G-Series and G(GT) Turbochargers

The G-Series section includes turbochargers using modern G-style compressor and turbine wheel sizing, with multiple housing and flange configurations. Models such as G25-550 and G25-660 are popular for responsive street and track applications, while G30-770, G30-900, G35-900 and G35-1050 are more suitable for high-flow, high-power engine builds.

The catalog also includes G(GT) models, which use G-style wheels on GT-style turbo configurations. These are useful for buyers who want to combine modern wheel sizing with more traditional GT-style fitment options such as T25, T3 or T4 turbine inlet configurations.

  • Standard and reverse rotation options
  • Wastegated and non-wastegated options
  • V-band turbine inlet and outlet configurations
  • T25, T3 and T4 flange options
  • Listed power ranges from 300 HP to over 1000 HP
  • Displacement targets from 1.4L to 5.5L

Bolt-On Turbo Upgrades for EA888 and GM LTG Engines

The bolt-on turbocharger range is designed for customers who need a more application-specific performance upgrade. These products are especially useful for tuning workshops, importers and wholesalers serving Volkswagen, Audi and GM performance markets.

For EA888 Gen II and Gen III engines, the catalog includes models such as K04-064H-370, K04-064Z-370, EA28R series and EA38R series turbochargers. These products cover transverse and longitudinal engine layouts, with power levels ranging from 370 HP to 750 HP depending on the model.

For GM LTG engine applications, the catalog includes ATS-500R and ATS-650R models, with G25-660 and G30-770 style upgrade options.

  • Ball bearing or dual ceramic ball bearing construction
  • Journal bearing options for selected K04 upgrades
  • Direct-fit original oil and water feed compatibility
  • Listed 15% increased response rate on selected models
  • Application coverage for Audi, Volkswagen, Chevrolet and related 2.0T platforms

How B2B Buyers Can Choose the Right Upgrade Turbo

Choosing the right performance turbocharger depends on more than the HP number. Importers and workshops should check the full technical specification before placing a wholesale order.

  • Target engine displacement
  • Desired power range
  • Compressor wheel size
  • Turbine wheel size
  • Turbine inlet flange
  • Turbine outlet flange
  • AR ratio
  • Wastegate requirement
  • Standard or reverse rotation
  • Universal or bolt-on installation type
  • Oil and water feed compatibility
  • Vehicle platform and engine generation

For universal turbochargers, the buyer must confirm the custom kit design, manifold flange, downpipe setup, oil line configuration and tuning requirements. For bolt-on turbochargers, the buyer should confirm the exact engine generation, vehicle layout, OEM turbo type and installation requirements.

Why This Catalog Is Useful for Wholesalers and Workshops

A complete performance turbocharger catalog helps B2B buyers serve different customer groups. Universal GTX and G-Series turbos are ideal for custom builds and tuning projects, while bolt-on EA888 and GM LTG turbochargers are easier to position for workshops and vehicle-specific upgrade markets.

For wholesalers, the most practical strategy is to stock fast-moving bolt-on options while offering larger universal turbochargers as order-based performance solutions. This allows distributors to cover both daily-demand tuning products and specialized high-power builds.

Performance Turbocharger Selection Guide

For smaller engines between 1.4L and 2.0L, GT20, GT22, G25-550 and G25-660 models are commonly positioned as responsive upgrade options. For 1.8L to 3.0L applications, GT28, GT30, G30-660, G30-770 and G30-900 models provide a wider performance range. For larger displacement or higher-power builds, GT35, G35-900 and G35-1050 models are more suitable.

For vehicle-specific applications, EA888 bolt-on upgrades provide a more direct product path for Audi and Volkswagen tuning markets. GM LTG bolt-on options can serve Chevrolet, Cadillac ATS-style and related 2.0T performance applications.

Important Note About HP Ratings

The HP values listed in this catalog are reference ranges based on turbocharger configuration. Final engine output depends on many factors, including engine condition, fuel system, ECU calibration, intercooler setup, exhaust flow, boost pressure, supporting hardware and installation quality.

For B2B orders, buyers should confirm the target vehicle, engine code, installation layout and performance goal before selecting a turbocharger.

FAQ
