The competition engine of the HONDA INTEGRA 1.8 VTEC from the PSI Motorsport for the Belgian Proximus Procar Championship '98 has been designed using SIMOTTO.

The tuning of the engine had to respect the regulations of the DTC (Deutscher Tourenwagen Cup), where the exhaust manifold is free, the intake and exhaust valve lifts are free, but must respect the A and B dimensions of the original cams and the max lift is limited.

A new optimised exhaust manifold and a new optimised exhaust valve lift has been designed for the original road engine using SIMOTTO.
