Discussion and questions related to the course Introduction to Engine Tuning
A friend of mine has damaged his FA20 and looking for a long term solution.
As we are out of 98 or 100 octane fuel and 95 is the only choice to go, would it be a better idea to get the engine with lower CR? He is looking to buy a stage2 short block from IAG Performance with 10.5:1CR.
He is not going to fit the turbo or compressor for now. Cylinder heads remains the same, btw.
Can it still run the DI and stock ECU or some mods required?
