Hello MT municipality it is about a Z22SE in the Vectra C … the engine is also traded as L850 of GM and thus installed in tens of other vehicles … Performance increase is the topic .. I found the following post Quote: A 2.2-liter, four cylinder engine from the new aluminum ECOTECfamily – which will premiere in Europe in the Astra Coupé – also powers the Speedster. The engine is constructed from aluminum alloy and weighs a mere 138 kilograms. It produces 108 kW (147hp) at 5800 rpm m with a maximum torque figure of 203 Nm, whereby 90 percent of this is available at 1800 rpm.” 203 Nm is 147 ft-lbs. 138 kg is 304 lb. 147 hp is awesomely low for a 2.2 liter engine, however. Hopefully it should be able to do well over 200 hp with some tuning (and no turbos) can only agree with the author 147 hp is not really a lot for a 2.2 l engine … so I’m looking for RENEWABLE suggestions to turn a bissel on the wheel YeahOne.com offers a power kit for this engine where the motorle but unfortunately not in the mail order (have with those telebimst) otherwise only without guarantee 🙁 .. so proposals PLEASE
