    Question Improving my Power?

    Hi,

    I've got a 58 Plate Vectra SRi 1.8i VVT.

    I bought this car outright so there's no finance company involved or anything.

    What's the best way to improve the performance and which one's would/would not affect the warranty?

    Thanks for your help!

    TBH mate most people here will tell u not to bother, which is probably the best advice.

    However there are a few things u can do to bring BHP up but will cost a fair few £!
    Changing your air filter to a K&N panel and doing the 'airbox mod' will give give better throttle response and maybe 1 or 2 BHP. Getting a 'cat-back' exhaust should free up a few ponies. And a remap, which only gives a 10-15% increase in BHP. if u want anything more then that and you'll be spending loadsa ££££££'s and should probably have bought a car with a bigger better engine with a turbo! lol

    ive got a 1.8 vvti, ive done the air filter, airbox mod, and an exhaust should b on its way soon. i am planning for a remap but thats it for tuning for me.

    hope this helps
