this cylinder is very fast out of the box! i opted for the contessa over the corsa because i figured i can always port the exhaust to corsa spec in the future if i want more power. that being said, it friggen rips outta the box. with 9.1:1 gears, 19mm phbg and a PG long exhaust my DIO ZX hits mid 60s. definitely a ripper!!
