Turbosmart Turbochargers

Updated May 12, 2026

For the broader performance-tier brand cross-shop that Turbosmart's wastegates equip, see the Read the high-performance turbocharger guide — covers the Garrett, Precision, and BorgWarner turbos Turbosmart products typically pair with.

Brand Overview — What Turbosmart Actually Sells

Turbosmart is a Sydney, Australia-based performance aftermarket company founded in 1997. The brand built its reputation across 1998-2015 on wastegates, blow-off valves, and boost controllers — the accessory ecosystem around a turbocharger rather than the turbocharger itself. The Turbosmart-branded turbocharger product line launched in the 2010s, but the brand still earns more on accessories than on turbos.

The product portfolio splits across five product categories. External wastegates (Hyper-Gate 38mm covering 250-450 hp builds, Hyper-Gate 45mm covering 400-700 hp, Hyper-Gate 60mm covering 600-1,200 hp, Pro-Gate Lite 38mm budget-tier, Race-Port HyperGate 60mm V-band race-spec). Internal wastegate actuators (IWG75 series in OEM-replacement form factor). Blow-off valves (Plumb-Back entry-tier, Dual Port, Big BOV, Race-Port race-spec). Electronic boost controllers (e-Boost2 entry-tier, e-Boost Street, e-Boost Race with dual-channel data logging). Fuel pressure regulators and turbo accessories (oil drains, oil restrictors, intercooler couplers, gasket kits).

"Every serious aftermarket performance build over the last fifteen years runs a Turbosmart or Tial external wastegate on a Garrett or Precision turbo. The turbo + wastegate combination is the right cross-shop; running a Turbosmart turbo with a Turbosmart wastegate is the unusual case." — r/Honda + r/Mitsubishi build-community synthesis on the documented brand-pairing pattern in the aftermarket performance space.

The Wastegate Product Line — Where Turbosmart Wins

Turbosmart\'s external wastegate catalog covers four sizes and two materials. Hyper-Gate 38mm for 250-450 hp builds. Hyper-Gate 45mm for 400-700 hp. Hyper-Gate 60mm for 600-1,200 hp. Race-Port HyperGate 60mm V-band for race-spec 1,000+ hp.

Each size ships with multiple spring rate options that cover different boost target ranges. The 38mm covers spring rates from 6 psi (0.4 bar) through 25 psi (1.7 bar) in roughly 2 psi steps. The 45mm covers 7 psi through 35 psi. The 60mm covers 10 psi through 45 psi. The spring rate determines the base boost target; the buyer adds an electronic boost controller (Turbosmart e-Boost2 or competitor) to modulate boost above the spring rate. Spring rate selection is application-specific: matching the engine\'s peak power RPM, the turbo frame\'s spool characteristics, and the required boost target curve across the powerband.

The fabrication quality on the Hyper-Gate line is documented top-tier — the valve body uses CNC-machined billet aluminum housing, the diaphragm is rated to 1,800°F sustained, and the spring rate documentation per part number is published in Turbosmart\'s technical library website. Rebuild kits ship for every size at $40-$80 per kit, making the wastegate a serviceable component rather than a wear-replacement.

The Blow-Off Valve and Boost Controller Lines

The Turbosmart blow-off valve catalog splits into four series. Plumb-Back BOVs (entry-tier, returns vented air to the intake) at $200-$300. Dual-Port BOVs (split between atmospheric vent and plumb-back) at $300-$400. Big BOVs (high-flow, larger displacement applications) at $400-$550. Race-Port BOVs (race-spec with V-band fittings and dedicated dump port) at $550-$700.

The boost controller catalog runs three tiers. e-Boost2 (entry-tier, single-channel, $400-$500). e-Boost Street (mid-tier with vehicle integration features, $500-$650). e-Boost Race (top-tier with dual-channel data logging and per-gear boost mapping, $750-$950). All three controllers integrate with any turbocharger and wastegate combination through standard pneumatic plumbing; the controller modulates manifold pressure feedback to the wastegate to target the programmed boost curve rather than the wastegate spring rate alone. A documented build running an e-Boost Race with logged per-gear boost mapping can hold 25 psi flat across gears 2-5 against a wastegate spring rated at 8 psi, freeing the buyer from spring-swap labor when the build target changes.

Turbosmart vs Tial — The Wastegate Brand Cross-Shop

Tial and Turbosmart are the two dominant aftermarket external wastegate brands, with comparable engineering depth and similar pricing. Tial MV-S 38mm at $380-$450 versus Turbosmart Hyper-Gate 38 at $350-$450. Tial MV-R 60mm at $650-$800 versus Turbosmart Hyper-Gate 60 at $600-$800.

Decision criteria. Distributor network in the buyer\'s region (Tial historically stronger in the US, Turbosmart historically stronger in Australia and Europe, both increasingly available worldwide through performance shops). Spring rate options (Turbosmart offers a wider range across the 38mm and 45mm sizes; Tial offers fewer spring rates per size but with tighter individual tolerances). Rebuild kit availability (both brands stock rebuild kits at $40-$80 per kit). Aesthetic preference (Tial signature blue anodized vs Turbosmart matte black or anodized red). Both are documented community defaults on serious aftermarket builds; the cross-shop is genuinely close on engineering criteria.

For the broader cross-engine cross-shop, the Read the cross-engine roundup covers documented OE-replacement and performance picks.

The Turbosmart Turbo Product Line — Newer to the Game

Turbosmart launched its own turbocharger product line in 2018 with the Powerstream / Performance series. The catalog covers selected frame sizes in the 350-800 horsepower band — narrower than Garrett, Precision, or BorgWarner. The Powerstream 5559 covers 350-475 hp on 2.0-liter applications; the Performance 6262 covers 500-700 hp on 2.0-2.4L; the Performance 6766 covers 700-900 hp on 2.4-3.0L displacement.

Documentation depth on the Turbosmart turbo line is lighter than the wastegate line. Compressor maps are published per frame but cover fewer operating points than Garrett or BorgWarner publishes. Aftermarket adoption in performance build communities has stayed limited — most documented dyno builds run a Garrett GTX, Precision PT, or BorgWarner EFR with a Turbosmart wastegate and BOV rather than running a Turbosmart turbo. The brand\'s reputation is structurally built on the accessory ecosystem; the turbo product line has not yet replicated that depth.

Turbosmart Decision Questions

Who makes Turbosmart turbochargers?

Turbosmart is an Australian company based in Sydney, founded in 1997 by Nic Cooper. The brand built its reputation on wastegates, blow-off valves, boost controllers, and dual-port BOVs across the import performance build community from 1998-2015. Turbosmart launched its own turbocharger product line in the 2010s (the Powerstream / Performance series, since 2018) but turbo manufacture remains a smaller share of the company's revenue than wastegates and BOVs.

Are Turbosmart turbochargers any good?

For the wastegate, blow-off valve, and boost-controller product categories where Turbosmart built its reputation, the brand is top-tier — Turbosmart Hyper-Gate and Plumb-Back BOVs are the documented default in the aftermarket performance build community, used on countless Garrett and Precision turbo builds. For the Turbosmart-branded turbocharger product line specifically, the brand is newer to manufacturing turbos and the catalog is narrower than Garrett, Precision, or BorgWarner. Most aftermarket builds run a Garrett or Precision turbo paired with a Turbosmart wastegate and BOV rather than running a Turbosmart turbo.

What does Turbosmart make besides turbochargers?

Turbosmart's primary product portfolio: external wastegates (Hyper-Gate 38mm, 45mm, 60mm; Pro-Gate Lite 38mm; Race-Port HyperGate 60mm), internal wastegate actuators (IWG75 sized for OEM-replacement applications), blow-off valves (Plumb-Back, Dual Port, Big BOV, Race-Port), boost controllers (electronic boost controllers across e-Boost2 / e-Boost Street / e-Boost Race variants), fuel pressure regulators, and turbo accessories (oil drains, oil restrictors, intercooler couplers). The wastegate + BOV + boost controller core defines the brand more than the turbo product line.

How much does a Turbosmart wastegate cost?

Hyper-Gate 38 (smallest external wastegate, suits 250-450 hp builds): $350-$450. Hyper-Gate 45 (mid-size, suits 400-700 hp builds): $450-$600. Hyper-Gate 60 (large, suits 600-1,200 hp builds): $600-$800. Race-Port HyperGate 60 (race-spec with V-band flanges): $800-$1,100. Internal wastegate actuator (IWG75 OEM-replacement form factor): $200-$350. Turbosmart wastegates sit at the top of the aftermarket wastegate price band; the spring-rate options and rebuild kit availability justify the premium against unbranded alternatives.

Turbosmart vs Tial — which is better?

Tial and Turbosmart are the two dominant aftermarket external wastegate brands in the performance build community, with comparable engineering depth and similar pricing. Tial MV-S 38mm runs $380-$450; Turbosmart Hyper-Gate 38 runs $350-$450. Tial MV-R 60mm runs $650-$800; Turbosmart Hyper-Gate 60 runs $600-$800. Decision criteria: distributor network in the buyer's region, spring-rate options (Turbosmart offers a wider range across the 38mm and 45mm sizes), and aesthetic preference (Tial signature blue vs Turbosmart matte black). Both are documented community defaults on serious aftermarket builds.

Where are Turbosmart products made?

Turbosmart designs and engineers in Sydney, Australia. Manufacturing splits between Australian assembly for premium-tier products (Hyper-Gate, Race-Port lines) and Asian production partners for high-volume entry-tier products. The Australian engineering depth shows in the documented testing data Turbosmart publishes per spring rate and per wastegate size; the Asian production partners deliver the cost competitiveness against unbranded alternatives. Country-of-origin labels on each product specify which production line.

Do Turbosmart wastegates work with any turbocharger?

External Turbosmart wastegates (Hyper-Gate, Race-Port) work with any turbocharger that runs an external wastegate configuration, regardless of brand. Internal Turbosmart actuators (IWG75) replace OEM internal wastegate actuators on specific applications cross-referenced by part number. The wastegate sizing is independent of turbo brand; the wastegate sees exhaust gas pressure from the merge pipe upstream of the turbo turbine inlet, not from the turbo itself. Turbosmart product compatibility cross-references are published on the brand's technical library website.
