Best Turbo For 4 Cylinder: Compare T3/T4, GT28 and GT35

#1 · Best Overall

1. maXpeedingrods T04E Turbo Kit

• Dimensions: 30.35 x 16.06 x 12.68 in
• Weight: 35.8 lb

Best for: T3/T4 kit project builders.

Why it ranks #1: Fits stated 4-cylinder 1.5L–2.5L applications, includes a wastegate and oil lines, and lists 350HP at 7.5–14.5 PSI.

The T3/T4 hybrid turbo comes with a wastegate and oil feed-and-return line kit, giving 4- to 6-cylinder project builders several core components together. Its listed 1.5L–2.5L engine range and 25–35 psi output capability frame it for a custom turbo project, rather than a direct replacement.

The 3-inch inlet and 2-inch outlet give builders concrete connection dimensions to account for when planning the intake and charge-air path. Its T3/T4 four-bolt exhaust inlet flange helps identify the manifold interface, while the included oil lines and wastegate cover key parts of the setup. The listing says a turbo manifold, modifications, and other accessories are still needed, so this is a project component package, not a complete bolt-on conversion.

Skip it if you need a complete bolt-on turbo package; the listing requires a manifold, modifications, and additional accessories.

A hands-on builder planning a 1.5L–2.5L four-cylinder turbo project can use the included lines and wastegate as a starting point. Allow for manifold work, modifications, and supporting parts before treating it as a complete setup.

#2 · Universal Fitment

2. Autodevil T3 T4 Turbo

• Weight: 16.46 lb

Best for: Universal T3/T4 replacement shoppers.

Why it ranks #2: Its stated 1.5L–2.5L fit covers any 4- or 6-cylinder engine, with T3/T4 intake and standard T3 five-bolt exhaust patterns.

T3/T4 four-bolt turbine-intake and standard T3 five-bolt turbine-exhaust flange patterns give this Autodevil turbo two specific interfaces to check during a replacement or custom build. The listing covers 1.5L–2.5L four- or six-cylinder engines and describes the unit as a 400+HP Stage III charger.

The listed flange patterns help a buyer compare manifold and exhaust connections before planning installation, while the stated 1.5L–2.5L engine range sets a useful starting boundary for the intended application. Autodevil describes its dimensions as matching original specifications, but also advises checking compatibility with the specific vehicle. That makes careful model and interface verification central to the buying workflow; the supplied listing also points buyers to a troubleshooting guide for installation issues.

Skip it if you want an exact-fit replacement without checking vehicle and flange compatibility; the listing calls for application verification.

A builder comparing a universal T3/T4 unit for a 1.5L–2.5L four-cylinder can use the flange details to screen a setup. Choose it only after checking the vehicle application and both turbine-side connections.

#3 · Ball-Bearing Option

3. maXpeedingrods GT28 Turbo

• Dimensions: 9.45 x 8.66 x 10.24 in
• Weight: 17.42 lb

Best for: Compact GT28 engine builds.

Why it ranks #3: Targets four-cylinder 1.5L–2.0L engines and lists dual ceramic ball bearings, a billet compressor wheel, and output up to 350BHP.

Dual ceramic ball bearings distinguish this GT28 turbo from simpler bearing layouts, while its listed 1.5L–2.0L four-cylinder range and output up to 350BHP define its intended scale. The stainless-steel turbine housing is rated to withstand 1868°F, a concrete specification for buyers planning a compact performance setup.

The 1.5L–2.0L engine range helps narrow the application, and the listed Nissan 240SX fitment gives owners a specific vehicle reference to check. A standard T25 flange provides an installation interface; the listing says conversion from a T28 flange to T25 requires an adapter, so that connection affects parts planning. The dual ceramic ball bearing specification and billet compressor wheel identify key turbo components, while the 17.42-pound weight may matter when organizing handling and installation.

Skip it if you need to connect a T28 flange without an adapter; the listing specifies an adapter for conversion to T25.

A builder planning a compact 1.5L–2.0L four-cylinder setup can consider this GT28 and its dual ceramic ball bearings. Check vehicle and flange fit, and include an adapter if converting a T28 connection to T25.

#4 · Broad T3/T4 Fit

4. maXpeedingrods T3 T4 T04E Turbo

• Dimensions: 9.84 x 9.06 x 11.02 in
• Weight: 15.87 lb

Best for: T3/T4 1.5L–2.5L builds.

Why it ranks #4: Lists 4-cylinder fitment from 1.5L–2.5L and up to 400 hp, with gaskets and T3/T4 four-bolt inlet and T3 five-bolt outlet patterns.

A T3/T4 turbo rated for up to 400 hp comes with gaskets and is listed for 1.5L–2.5L four- or six-cylinder engines. Its named vehicle applications include Honda Civic, CRX, and BMW 318i models, offering project builders specific fitment starting points rather than a vehicle-neutral description alone.

The T3/T4 four-bolt exhaust inlet and standard T3 five-bolt downpipe outlet give buyers two connection patterns to compare with their manifold and exhaust before installation. Gaskets are included, providing parts for the turbo connection work, while the stated engine range frames the intended displacement. The long vehicle list can help with initial screening, but specific model and year fitment still needs checking against the listing; these flange details make interface planning particularly important.

Skip it if you need an exhaust outlet other than the listed standard T3 five-bolt downpipe pattern; check your connection before choosing it.

A builder working on a listed Honda, BMW, or other compatible 1.5L–2.5L application can use the stated output and flange patterns to screen this turbo. Match both exhaust interfaces and the vehicle fitment before installation.

#5

5. maXpeedingrods T3 Turbo

• Dimensions: 10.63 x 9.06 x 11.81 in
• Weight: 20.8 lb

Best for: V-band exhaust setup builders.

Why it ranks #5: Covers 4-cylinder 1.5L–2.5L engines and claims up to 420 hp; check available space and confirm its four-bolt inlet and V-band outlet suit the build.

A V-band turbine outlet sets this maXpeedingrods T3 turbo apart for builders whose exhaust setup uses that connection. It is listed for 1.5L–2.5L four- or six-cylinder engines, with output up to 420 hp and applications including BMW, Honda, and Toyota models.

The four-bolt exhaust inlet gives a defined interface to compare with the manifold, while the V-band outlet—with listed 2.5-inch inner and 3.1-inch outer diameters—helps determine whether the exhaust connection suits the build. Its 1.5L–2.5L engine range and 420 hp figure set the stated application and output boundaries. The listing also advises checking available installation space, so buyers should assess both clearance and flange compatibility before committing to the layout.

Skip it if you need a standard T3 five-bolt downpipe outlet; this turbo lists a V-band outlet instead.

A builder with a compatible 1.5L–2.5L engine and V-band exhaust plan can use the outlet dimensions to assess this turbo. Check engine-bay space, manifold fit, and the V-band connection before installation.

#6

6. maXpeedingrods GT28 Street Turbo

• Dimensions: 6.1 x 5.71 x 4.13 in
• Weight: 8.55 lb

Best for: Nissan 240SX GT28 builds.

Why it ranks #6: Fits four-cylinder 1.5L–2.0L applications and claims up to 350BHP, with a billet compressor wheel and standard T25 flange.

A billet compressor wheel and gaskets come with this GT28 turbo, listed for 1.5L–2.0L four-cylinder engines and output up to 350BHP. Its stated Nissan 240SX 1989–1998 application gives owners a specific fitment reference, while the silicon-molybdenum turbine housing is rated to 1562°F.

The listed Nissan 240SX application provides a concrete starting point for checking vehicle compatibility, and the 1.5L–2.0L range defines the engine displacement stated for the turbo. Its standard T25 flange helps identify the connection to plan around; converting a T28 flange to T25 requires an adapter. The included gaskets support installation planning, while the billet compressor wheel and alloy turbine wheel describe key components without removing the need to verify the vehicle and flange arrangement.

Skip it if you need to convert a T28 flange to T25 without an adapter; the listing says an adapter is required.

A Nissan 240SX owner or builder planning a compatible 1.5L–2.0L four-cylinder setup can consider this GT28 with its billet wheel and included gaskets. Verify vehicle and flange fit, and plan for an adapter when converting T28 to T25.

#7

7. maXpeedingrods GT35 Turbo Kit

• Dimensions: 30.28 x 16.1 x 12.56 in
• Weight: 41.4 lb

Best for: Larger-displacement custom builds.

Why it ranks #7: Lists 4-cylinder fitment for 2.5L–6.0L engines and up to 400HP at 7.5–14.5 PSI, but requires compatibility and space checks.

The GT35 kit pairs a turbocharger with a 27-by-7-by-2.5-inch intercooler and oil feed-and-return line, giving a custom build several major components in one package. Its listed 2.5L–6.0L engine range and output up to 400HP at 7.5–14.5 PSI distinguish it from smaller-engine options.

The included intercooler provides a defined component for the charge-air system, while the oil feed-and-return line addresses turbo lubrication connections during project planning. Its T3 flange and 0.63 A/R turbine specification give builders concrete details to compare with their intended manifold and setup. The listing warns that this is not vehicle-specific, space must be checked, and modifications may be needed; professional installation is recommended, and instructions are not included.

Skip it if you need a vehicle-specific kit with included instructions; this universal package may need modifications and professional installation.

A fabricator working with a 2.5L–6.0L engine can consider this package when an intercooler and oil lines suit the build. Check available space and flange fit, and plan for possible modifications and installation help.

#8

8. maXpeedingrods GT35 Turbo

• Dimensions: 10.98 x 9.29 x 11.85 in
• Weight: 19.18 lb

Best for: High-output GT35 project builders.

Why it ranks #8: Offers stated 4-cylinder fitment from 2.5L–6.0L and up to 600 HP, though it uses a journal or floating bearing and has broad vehicle listings.

A listed output of up to 600 HP sets this GT35 apart for 2.5L–6.0L four- or six-cylinder projects. Its extensive vehicle application list, including Honda Accord and Jeep Grand Cherokee models, gives buyers concrete starting points for fitment research, while the journal-bearing design identifies its bearing type.

The broad engine range and listed vehicle applications help buyers narrow whether this GT35 belongs in their project, though the application still needs to match the vehicle and installation. Its journal, or floating, bearing specification is useful for comparing the unit with a build’s chosen turbo configuration. The 600 HP output figure signals the listed capability, while the product’s 10.98-by-9.29-by-11.85-inch dimensions give fabricators a reference when considering space in the engine bay.

Skip it if you specifically need a ball-bearing turbo; this GT35 is listed with journal/floating bearings.

A fabricator planning a 2.5L–6.0L build with a high listed output target can assess this GT35 against available space and application fit. Its journal-bearing design is a boundary for buyers requiring ball bearings.

#9

9. Stigan Audi 2.0T Turbo

• Dimensions: 16 x 15 x 15 in
• Weight: 27 lb

Best for: CAEB Audi replacement owners.

Why it ranks #9: This is an exact-fit replacement for specified Audi 2.0T CAEB applications, not a universal upgrade; it requires no modifications according to its listing.

An exact-fit replacement turbocharger with gaskets targets Audi A4, A5, A6, Q5, and Allroad models using the CAEB 2.0T engine code. Its no-modification fitment claim makes this a repair-oriented choice for a vehicle already equipped with a turbo, not an upgrade for a naturally aspirated engine.

The exact-fit replacement format and included gaskets support a repair workflow centered on replacing the existing turbo rather than fabricating an add-on installation. STIGAN states that no modifications are required and describes the fit and finish as OEM-style, which can simplify planning for the listed CAEB application. Its premium ISO/TS 16949 parts and stated durability focus are relevant to owners seeking an original-equipment-standard replacement; fitment still depends on the engine code and vehicle listing.

Skip it if you are adding a turbo to a vehicle that was not factory-equipped with one; this unit replaces an existing turbo.

A CAEB 2.0T Audi owner replacing an existing turbo can favor this exact-fit format and included gaskets. Check the vehicle fitment listing and engine code; it is not intended for a non-turbo conversion.

#10

10. BuyAutoParts Audi 2.0T Turbo

• Dimensions: 23 x 14 x 12 in
• Weight: 28 lb

Best for: Exact-fit CAEB turbo repairs.

Why it ranks #10: Its stated role is an exact-fit replacement for listed Audi 2.0T CAEB vehicles, rather than an add-on turbo for a four-cylinder build.

BuyAutoParts identifies this brand-new turbo as an exact-fit replacement for CAEB 2.0T Audi A4, A5, A6, Q5, and Allroad applications. That fitment focus supports a repair workflow aimed at restoring an existing turbo-equipped vehicle, rather than adding forced induction to an engine without a turbo.

The exact-fit claim and OEM-style fit and finish speak to owners seeking a replacement that follows the original installation rather than a custom setup. BuyAutoParts says each part is checked and thoroughly inspected before leaving the factory, while its premium ISO/TS 16949 quality and original-equipment standards provide further context for the replacement choice. The listing directs buyers to verify fitment through the vehicle dropdown and OE number, so matching the CAEB application is essential.

Skip it if you are converting a vehicle without a factory turbo; this listing is for replacement of an existing unit.

A CAEB 2.0T Audi owner seeking a replacement can use the exact-fit and inspection details to assess this option. Match the vehicle listing and OE number first; this is not a universal four-cylinder upgrade.
