Hi Adi,
Glad to hear that the car is doing well.

You will need an intake, bigger intercooler, fuel pump and larger turbo to upgrade the breathing of the EJ20. Fresh plugs and a throttle clean will also be recommended. Although the EJ20 IMO is a very tough motor, but bear in mind that the engine has done close to 200,000km, so mods need to be planned carefully.

This bugeye came in with a basic 3" custom mild steel exhaust system. Rest of car is stock. Odo was at 191,000km.

We installed the HKS EVC-S and did a flash tune, quickly restoring the lost power on this vehicle. Boost was spiked it to 1.1bar at 4500rpm, reducing it to 0.9bar after that for safety reasons.

Vehicle made 138hp before the EVC-S and tune. Safe tune made 40hp gain ATW to 184hp with a massive 50% Torque gained. Lack of airflow and low boost made it difficult to smoothen out the graphs fully, but Torque and Power were reinstated to this bugeye.

Below is the dyno chart:
