SR20 T3T4 .48 and 6Boost T3 Manifold Combo
Enquiry only — online purchasing is not available for these combos. Availability and the complete supplied specification must be confirmed with Turbo Bits before ordering. These examples are not advertised as ready for immediate dispatch.
SR20 RWD budget T3T4 .48
Combo price: NZ$2,074.15 including GST
- One complete TBR T3T4 billet-wheel journal-bearing turbo, 0.48 A/R T3 turbine housing.
- One 6Boost SR20 RWD T3 single-entry manifold.
For rear-wheel-drive SR20 custom installations. This is the 0.48 A/R T3 version, not a T2 or 0.63 A/R substitute. The turbo uses a T3 inlet and five-bolt turbine outlet. Confirm the exact wastegate arrangement, outlet connection, housing clocking and clearances before specifying the installation.
Price breakdown: turbo $749.00 less 15% = $636.65; manifold $1,437.50 at full retail.
Prices are in NZD and include GST. Each displayed base combo price includes 15% off the TBR turbo only, with the manifold at full retail. The discount is already included. Pricing checked 28 October 2026; confirm your complete quotation and delivery details with us.
The 6Boost manifold has no wastegate flange welded on; gate selection, flange and fabrication need to be agreed with your installer. The source listing includes mounting studs and a T3 inlet gasket.
Custom installation and exclusions
The base prices cover two-part component packages for custom installations, not complete bolt-on kits. Each includes one complete turbo with the stated turbine housing and one named manifold. Turbo Bits / TBR turbos are own-brand products, not genuine Garrett.
No wastegate is included in the base price. One selected gate and its supplied hardware are added only when included in your confirmed quotation. Additional gate flange work and fabrication, dump pipe/downpipe, exhaust, intake and intercooler piping, oil/water lines, optional fuel-system upgrades, radiator, ECU changes, tuning and installation are not included. Other gaskets, clamps and fasteners are separate unless specifically confirmed.
Matching T3 flanges do not establish vehicle fit. Confirm the cylinder head, exact housing, gate arrangement, clocking, fastener access, bonnet, steering, accessories and exhaust clearance with your installer. Supporting upgrades and professional tuning may be required. No horsepower result or vehicle-specific fit guarantee is implied.
Availability and timing
Complete-combo availability is unconfirmed. The 6Boost manifold is not recorded as in stock. An approximately 8–10 week 6Boost lead time is an owner-supplied estimate only, subject to supplier confirmation; it is not a promised dispatch or delivery date.
Optional wastegate enquiry choices
The base price includes the turbo and manifold only. Add one of the gate components below only after we confirm your installation plan and availability. These gates are separate components requiring custom fabrication, not pre-fitted or guaranteed bolt-on options.
When selected with a combo, a Turbo Bits wastegate receives 10% off its regular retail. Turbosmart wastegates remain at full retail. The turbo discount stays at 15%; the manifold stays at full retail. All amounts include GST.

For 6Boost, the manifold listing provides for a 45, 50 or 60 mm gate but has no flange welded on. The listed 45/50 mm gates require the fabricator to confirm sizing and use the gate’s matching supplied flanges and clamps. Aeroflow AF8447-4000 is listed for a single 50 mm gate; starter-pipe fabrication, flange interface and position still need confirmation. 40 mm requests, and 45 mm on the Aeroflow option, need a separately checked custom installation plan and are not standard options here.
Turbo Bits gates are listed with fittings, flanges, clamps and one preinstalled 7–9 psi-range spring. The listed standard Turbosmart Gen V gates include matched inlet/outlet weld flanges and clamps, valve seat, collar tool, fittings and spring kit; these selected black SKUs have a 14 psi spring installed. Do not assume cross-brand flange compatibility or add a duplicate flange kit.
Gate choice does not establish complete-combo stock. Confirm the final gate, spring setting and hardware before ordering. Welding, installation, branch/outlet pipework, boost-control plumbing and tuning remain extra. No checkout is available from these enquiry pages.
