Kindly help guys' My car is opel Vita 1997/ Japan import.

The main problem am facing is I have no Idea where I can get my " Vehicles security code" I have done some reading I have found possible to get it in the car pass or radio pass' and I don't have an Idea to get these things.
Please can any one assist me to get the security code for my car?

Hi Michael

There are no superchargers that fit your car. Realize that your engine is 22 years old and wasn't exactly the model of durability even when it was built. Supercharging it would likely blow that engine.

If you're serious about performance with that car. I would recommend doing a engine swap to a carburated 302 (5.0L) V8. It would cost maybe $1000 for the engine and the labor to have the swap done would likely cost another $1000, but the car will be much quicker.

If you're looking for something simple, I'd make sure that all the routine maintenance has been done and then get a custom cat-back performance exhaust built by an exhaust shop. It will cost roughly $200 and maybe give you 5 hp.

thanks... so x, y, or h pipe exhaust system? which ones better and which brands
