    astra g mod benefits?

    was just wondering how (on average) the following mods will impact on the cars performance; bhp, mpg, top speed, and 0-60

    vectra c intake
    airbox deristrict
    new panel air filter

    also would like to know how much would cost:

    - a new manifold and stainless steel exhaust
    - chip remap
    - induction kit
    also any recommendations on these would be appreciated!

    what gains would i get on the 1st 3, and following 3?

    veccy c pipe airbox mods + panel arent going to give many bhp gains but will feel much more responsive as above engine size + model does help tho

    veccy C, air box and filter are well worth i go .. they're cheap and easy to DIY
    if you don't like it .. put it back to standard!

    everything else .. well it depends what lump you have

    I had a quote from courtneys for a remap and it was £295 That was on my 1.8 SXi (x18xe1 engine)

    As said airbox mods wont see much gain but will be more responsive

    Exhaust prices vary - depends what you want mate

    sounds fair.. what benefits did you see from the remap? was this after a full manifold and exhaust system change?

    what different type of exhausts are there?

    Airbox mods and cheap catback for me (Z16XE) = 117bhp/131ftlbs vs the OEM figures of 98bhp/113ftlbs...

    That's around a 20% gain for not much at all really...

    With a decent exhaust manifold and remap you may well see 125-130bhp but at a guess, you won't gain much torque over the ~130ftlbs figures though, and the bhp increases tend to be at the top end of the rpm range...overall these engines are very tuneable, and my car pulls very very nicely compared to how it was before

    sorry for being a noob but to which version does the Z16XE engine apply?

    what is a catback? :X lol

    and also, with these mods has your fuel economy increased slightly?
