Hallows I drive an Opel Astra G 2.0Liter 16V. With the x20xev engine. What is there for cost-effective possibilities to increase the acceleration or the Ps number of the engine ? There is also the Astra OPC with 160 Ps, is this not almost the same engine with other software ? From a speed of approx. 170 km/h the car starts to become a little too shady, there are still possibilities to make something on the chassis ) (should everything after possibility relatively swinging h his) Come from Dinslaken (46539), someone knows how to get started for any tuning parts or modifications in Duisburg, Oberhausen etc. ? Found the following today : http://cgi.ebay.de/…6V-Motor_W0QQitemZ290266451027QQcmdZViewItem?… Would this part bring something because it is not so expensive now (so far…) Thank you Sebastian
