A one-owner EVO 9 brought to us with issues that had stumped other tuners. Diagnosed, rebuilt, and tuned to 244kW at Step Up Automotive.
This EVO 9 with ONE owner came to our door with a few issues that had been bothering the owner — and had bothered a few tuners in the past. The customer wanted our technicians to locate the issue with the car, service it, and install some upgrades in the engine compartment.
Specialist diagnosis using years of chassis-specific experience.
Performance gains measured on our in-house Mainline Dyno.
A full service was carried out on the vehicle. After servicing the client's vehicle, our qualified technicians found the issues promptly from years of experience with EVOs. Past human errors our team has found — such as the front balance shaft timing being out by a full 360 degrees, causing an engine harmonic and vibration.
The team progressed to removing the head for some light porting. The head was reassembled using upgraded ARP head studs. A Plazmaman intake manifold was fitted, along with a new HKS timing kit featuring a new water pump and genuine EVO oil seals. The fuel system received all new braided fuel lines and fittings throughout, plus 880cc injectors so the owner could stay on 98 premium unleaded. An ATP Gold turbocharger and Kelford 272 camshafts complete the package.
Onto the dyno — the vehicle made a neat and snappy 244kW at all four wheels with only 23PSI of boost on BP 98 Premium Unleaded. The power was achieved whilst still retaining a 200-cell catalytic converter, which was giving it a restriction.
Most importantly the owner was very impressed and satisfied with how much faster the vehicle feels on the road — and there's talk of further modifications with our team at Step Up. The one-owner EVO 9 is a very rare car and a pleasure to be a part of this build.
We know these cars better than most. Bring it in and let's see what's possible with your build.
