This turbo is externally the same as a stock EVO9 turbo, it uses the larger diameter EVO9 compressor housing and bearing housing found in the 2006 models. It uses our 700cfm 69-5 billet compressor wheel and our enlarged 11 blade turbine wheel. This combination of increased compressor and turbine flow results in a very broad powerband and stock like boost response while still being capable of well over 400whp.

This turbocharger operates very well in the 20-22psi range on pump gas, and 24-28psi on E85 and 26-32psi on C16. Customers who desire even quicker spool up and never plan on running boost higher than 22psi can benefit from selecting the 9.8cm2 housing. The penalty for running the 9.8cm2 housing is much less obvious when coupled with the larger 11 blade turbine wheel and the increase in back pressure from the smaller housing is negligible until boost exceeds 22psi. To this end we are trying to obtain the very rare 9.0cm2 housing to gain even better bottom end power and response - we'll update on this topic in the future.

The turbine flow maps shown below shows how the choke flow of the turbine varies with changes in the turbine nozzle area.

The 18psi wastegate actuator is strongly recommended for applications where the boost pressure will always be 20psi or higher.

The turbine housing gasket match port job is recommended if using a gasket match ported manifold.

The turbine housing ceramic coating is recommended to reduce heat in the engine compartment, particularly useful if the factory heat shields are missing.

The turbo can be ordered with either 9.8cm2 or 10.5cm2 single flapper housings. ***This is currently on back order from Forced Performance for about 4-6 weeks***
