Hi there guys. i have a corsa 1.2 16v. in the last 12 14 months i have been driving my car was completely standard and i was extremely surprised how fast it was. so i fitted a induction kit with cold air feed, a fuel pressure regulator and power boost valve, at the moment the fuel is running at 2 bar. it also has a sebring big bore backbox, which is probably as quiet as the standard backbox, i don't know what my power figures show at the moment, a dyno run is in the near future!!!
now my problem! my dads mate is a experienced car engine tweaker so he made me a custom de-cat, which i hate to say has caused me a massive increase in back pressure and obviously power at the top end of my revs
so the question is do i fit it with a standard c.a.t or a sports cat??
i also have a full exhaust system with manifold upgrade to try soon
i want to keep it as a 1.2 but make a lot of people unhappy whats just blew them off lol it does quite alot now..
my main purpose is to attend track days in 2011, santa pod, silverstone.
i would buy another car but none interest me and a daren't have a engine upgrade incase i have a accident.
