Cavalli Turbo Stage 4 Ball Bearing Turbo
have applied their Patented Triplex Ceramic Ball Bearing Billet turbo technology to this
Direct Replacement Drop-In Turbo. Their Stage 3 and Stage 4 WRX/STI turbos utilize a 3
inch compressor cover inlet. This may require some modifications to the up pipe bolt
holes and/or turbo bracket to be able to clear the 3¨ intake pipe (they have tested it with
the Perrin 3¨ inlet pipe) at the TGV. You may need to trim the outer TGV housing slightly.
This is a tight fit for the intake pipe and the silicone will be pinched a little to fit. This is
normal. They are packing a lot of power in a small space. They chose a 62mm inducer/
62mm exducer for their Stage 3 application for enthusiasts who are looking for up to a
90% increase in power. It is recommend to use of 1000cc injectors for 91/93 octane
and 1300cc for E85 applications. They utilize a Turbosmart wastegate actuator to help
stabilize boost on this high boost application. They do not recommend large diameter
aftermarket exhaust manifolds/headers as a diameter over 1.25" drastically reduces
exhaust energy and will move the power band to a normally less than desirable range
for a street driven car.
