One of our most extensive builds to date: a 2007 997.1 Turbo.
The car came to us following poor calibration work by a well-known tuner, which led to a spun con rod bearing on cylinder 5. The failure caused significant damage to the crankshaft and distributed bearing material throughout the engine.
Given the extent of the damage, we opted for a complete in-house engine rebuild — with a focus on performance, durability, and long-term reliability. If we were rebuilding, it had to come back stronger.
The process began with a full teardown and inspection. From there, the engine was comprehensively upgraded using high-quality components throughout. Key elements of the build include a brand new genuine crankshaft, an upgraded GT3 oil pump, new main and big-end bearings, new timing chains and guides. We fitted Carrillo connecting rods along with Mahle Motorsport pistons and liners, increasing engine capacity to 3.8 litres.
The cylinder heads were fully rebuilt with new valves, guides, and valve stem oil seals. Intake camshafts were pinned to eliminate the risk of sleeve slippage — a critical reliability upgrade on these engines.
Supporting modifications include Xona Rotor hybrid turbos supplied by AET, Do88 intercoolers and pipework, and a Fabspeed induction kit. Exhaust flow is handled by a Ninemeister race pipe with sports catalytic converters, while a Sachs performance clutch and pressure plate ensure the drivetrain can cope with the increased output.
To complement the power, the car was equipped with KW V3 coilover suspension, along with a KW hydraulic front lift system to provide additional ground clearance when required.
This is a serious build, engineered without compromise. We’re looking forward to seeing the results when Ninemeister puts it on the dyno.
The Mezger engine remains one of the most robust and capable platforms Porsche has produced, and we’re proud to have rebuilt this example to such a high standard.
