Evolution 8 GSR.
Full Performance
Build.
An EVO 8 GSR with an abundance of problems — head gasket failure, tune issues, coolant loss. Diagnosed, rebuilt, and tuned to 220+kW at Step Up Automotive.
Abundance of Problems. One Solution.
A customer brought in their EVO 8 GSR with an abundance of problems — one being a tune issue preventing it from running to full potential, and also losing coolant in the process. We took a systematic approach to diagnose and resolve every underlying mechanical hurdle to bring this JDM icon back to peak performance.
Systematic Diagnosis
Every problem found and fixed — nothing patched over.
Proven Results
Performance gains measured on our in-house Mainline Dyno.
How It Came Together
Diagnosed
Head lifted under boost, causing significant coolant loss and internal damage to the head gasket. Every fault found and documented before a single part was ordered.
Rebuilt
Head gasket replaced, full head service completed, ARP head studs fitted, timing belt replaced, and a full 100k service — all fluids replaced, ACD/AYC system flushed.
Aftermarket
Installation of a high-flow stainless exhaust manifold and a complete intercooler kit with high-temp silicone pipes — freeing up the restrictions holding this engine back.
Overview
A responsive tune delivered 220+kW at all four wheels. The customer's verdict: "Little yet feisty beast corners like it's on rails." A JDM icon restored and then some.
