TTE350+ IS12 upgrade turbocharger for VAG 1.8 TSI EA888.3 - hybrid turbo with over 350 hp output

TTE350+ IS12 upgrade turbocharger for VAG 1.8 TSI EA888.3 - Maximum performance in series production housing

With the TTE350+, TheTurboEngineers presents an advanced hybrid solution specifically for the 1.8 TSI EA888.3 engine of the MQB platform. Unlike previous upgrades, the original IS12 housing is retained, but is extensively modified to accommodate significantly larger components.

Technology & structure

The TTE350+ is based on the original IS12 turbocharger, which incorporates extended tip technology. The installed 9-blade turbine is modified by clipping in order to reduce the exhaust back pressure and improve throughput. The standard trunk assembly is replaced by a reinforced 360° thrust bearing that can withstand the increased loads in the long term.

Balancing & quality assurance

As with all TTE loaders, the TTE350+ is balanced in several stages - first each individual part at up to 2800 rpm, then the entire body assembly on a VSR machine at up to 250,000 rpm. A balancing log is included and can be traced via the serial number.

Advantages & special features

• Original IHI IS12 housing for inconspicuous appearance & easy installation
• Large CNC-milled compressor wheel with optimum response behavior
• Modified turbine with clipping for higher efficiency
• Maximum output: over 350 hp possible
• No separate turbo outlet necessary - already integrated
• Direct installation in original position possible
• Produced, developed and assembled by TTE in Germany

Compatibility

• VAG vehicles with 1.8 TSI EA888 Gen.3 and IS12 turbocharger
• z.e.g. VW Polo GTI, Seat Ibiza Cupra, Audi A1 1.8 TFSI

Notes on the conversion

The conversion is only possible if a functioning, undamaged IS12 turbocharger is sent in. If the housing cannot be used, TTE will provide a separate cost estimate. Additional modifications to the peripherals, exhaust system, software and engine are required for the target output of 350+ hp.

Conclusion:

The TTE350+ is the perfect solution for those who want to combine OEM-like looks with true high-end performance. Over 350 hp of power from an IS12 chassis - uncompromising, robust, TTE.
