The time has come to hit the dyno and tune our EJ257 STI powered GC Impreza!

Follow our journey of turning a 1997 2 door GC Impreza from 1.8 litres of base model fury into something with a lot more poke and rally pedigree.

Subarus are like Legos and this is no exception. However unlike Legos Subarus can also be rusty sh*t boxes.

This is going to be a long trek, filled with JDM goodness but worth the journey of making a USDM GC STI Impreza.

Oh yeah, we do tune Subarus a lot, so check that out below if you’re looking to make your Subaru faster, more reliable, and run better.
