Jamesthomson85 Hi i got a vectra c 2.2 sri petrol im customizing every thing from custom paint,custom bumpers .... but im a bit stuck with my engine its z22se i need to tune it up to get the most bhp out of it any one got any list of ideas and i dont want to by a vxr lol
Sjdickso Breathing, new filter custom air intake, the exhaust manifold sports cat. Then things get more expensive Cams, headwork, prob missed a bit out. Welcome to the site.
Jamesthomson85 I've done the air intake and bad ass exhaust I was going to get it remapped but after reading up remapping only gives me a small 15 Bhp what dosnt sound right surely I think your right going down the line of cranks ,cams and so on .
rushy I'd actually find out if it can be mapped first mate. All the big tuners have stopped saying they map the 2.2 in the Vectra C as its a different ECU as the z22se's in other cars.
Jamesthomson85 How hard and how much is it to change and reprogram a ecu because I really want to keep the z22se engine but at this rate I mite get a vxr engine or a v6 engine
