GTM Performance Engineering: MHI Twin Turbo Kit Official Release

Mike@GTM

This was done with our 3" downpipes with external wastegates. We'll be doing a 16g setup with internal wastegates here soon.

1) Either internal gates or external gates will do 10psi. That said, the external wastegate setup with 3" downpipes will make more power at 10psi than the internal gate setup at 10psi.

2) The Turn-Key Kit will come with Bosch EV14 650cc/min injectors with plug and play harnesses. We can add an external wastegate option for the Turn-Key kit.

3) As for dynojet numbers for the 16g and 20g setups, we will be doing testing on a car with 16g's soon. To really show what the 20g's can do, it would require a built motor.

4) That is flywheel horsepower.

We will be releasing the production/delivery dates shortly.

No drilling and tapping of the engine is required with this new kit. Also, since we're supplying an oil pan, there is no drilling and tapping of the factory upper oil pan either. As for pulling the motor, we keep the engine in the car for in house installs since the benefits of pulling the motor do not outweigh the extra time required to pull the motor in the first place.
