HKS manufacture a complete race FA20 which is bored out to 2.1 or 2.2 litres, with all forged internals, and wide angle crankshafts allowing for higher redline.
Pros: higher redline, forged internals
Owner reviews for crankshaft
Manufacturers
My RXPX300 crankshaft love fell off and in the BRP mechanics terms “danced around in my engine” causing $10,000 of damage. 61 hours in and BRP wouldn’t do anything as their “Goodwill” desk is swamped with defects
Cons: crankshaft love fell off
Mileage: 61 km
