You rebuild your engine and want more power?

We offer porting of the intake and exhaust ports.


But what is actually done during "porting"?
Porting involves redesigning the channels and opening and closing times of the intake and exhaust. This brings a changed engine characteristic with itself and by the change of the channels you reach a higher air flow which results in higher performance.

For street use, the Streetport is advisable. This has no disadvantages in terms of consumption or wear.

The increased performance is heavily dependent on the add-on parts, for example intake, catalytic converter as well as exhaust system and the tuning ( ECU ).

6Port / 231HP:
- a little more torque up to 4000rpm and turns a little more freely from 7000rpm towards the rev limiter
- it is advisable to send the lower intake manifold, so that we can match the shift rollers of the APV.

4Port / 192HP:
- significantly more torque and accordingly also power over the whole band, with hardened stationary gears from the 231hp model you can turn up to 9000rpm

We recommend to modify the software!

The engine must be disassembled for machining! From 80,000km mileage, it is also recommended to revise the irons.
