i will be lookin for a new backbox over the next week or so and wondered whats the best and where they can be brought from? currently iv got a 1.2 corsa b but will be changing the engine to a 1.6 8v / 16v havent quite decided yet, i was going to go with the 16v but a mate told me the 8v am better!!!
Tbh your going to need a decent performance system to make the most of any engine upgrades, so think longterm & only buy what will work with the new engine choice. IME a box suitable for a Corsa B GSi will be a thicker bore than the 1.2. Put it off until the engine swap is happening.
