GBT – 5471-3PWR – Super core – MA3 – Ported / Water cooled

GBT5471 V band Turbine housing – 3” compressor inlet

Probably one of the most suited turbos to the z20 series engine, this turbo with right manifold and supporting parts can provide a wide power band, we have had over 500HP from this turbo when using it to 100%. Sold as the perfect choice for 380-470 HP ( will do 500 flat out ) .

For fast road or all out time attack use this turbo is able to take it , we have used this turbo in UK Time Attack and proven it to be one of the best street car setups possible. With the right parts then this turbo will out spool the stock KO4 turbo targeting the same boost pressure – it will far over power the stock turbo unit by a long way.

On some setups with our cylinder head porting and some of our Cat fast road cams we have touched into the 500 LBS of torque , 400 Lbs is often the target for most !

The turbo itself is an all UK made item provided by Owen Developments , all we do is select the exact trim we want to run to match the output of the z20 engine for the fast road use based on knowing what we have learned.
 

It features a fully redesigned core with additional turbo oil filter built into the core package . Billet back plates hold the core either side , a billet HTA compressor wheel and conical nut holds everything in place. Revised cast housings for both the compressor and turbine .
