The Eventuri Carbon Turbo Tube for the Toyota GR Yaris and GR Corolla replaces the restrictive factory turbo inlet with a redesigned carbon fibre tube, engineered to supply the turbocharger with a larger and smoother volume of air.
Internal volume has been increased from 1,300cm³ to 2,200cm³ - an increase of almost 70% - with most of the gain concentrated around the critical bend leading into the turbo, where the OEM tube is most restrictive. The larger encapsulated air volume reduces wastegate duty cycle, sharpens throttle response and allows peak boost to be reached earlier in the rev range.
The main tube is manufactured from prepreg carbon fibre for rigidity under the vacuum generated by the turbo, connecting to a custom nitrile hose that mates to a precision CNC-machined aluminium flange bolting directly to the turbo. The flange is modular, so the system can be adapted to larger hybrid turbo upgrades using alternative flanges, sold separately.
Performance gain: 14whp / 19ft-lb in the low-to-mid range, 9whp / 9ft-lb at peak RPM (independently dyno tested at Limit+1, on a GR Corolla already fitted with an Eventuri intake)
Kit Includes:
- Carbon fibre turbo tube
- CNC-machined turbo flange
- Custom nitrile connecting hose
Key Features:
- Increases internal volume from 1,300cm³ to 2,200cm³, almost 70% more than the OEM tube
- Redesigned bend geometry removes the restrictive choke point at the factory turbo inlet
- 100% prepreg carbon fibre construction with no fibreglass, for a smooth internal surface and rigidity under vacuum
- Retains the OEM-style mounting point and breather ports for a plug-and-play installation
- Custom-moulded, rib-reinforced nitrile hose withstands vacuum forces and simplifies fitting
- Modular CNC-machined turbo flange, compatible with alternative flanges (sold separately) for larger hybrid turbo upgrades
Compatible With:
- Toyota GR Yaris (G16E-GTS)
- Toyota GR Corolla (G16E-GTS)
