    Default 206 GTI 138hp

    I have a 2002 GTI 138hp that I am currently getting ready for a road worthy and I was thinking because I have an exhaust manifold,
    Cat and intermediate pipe and injectors for a GTI 180 is it worth fitting them to this engine or will it just massively over fuel. It is the early injection system MM4.8P with cable operated throttle body which I believe has a 55mm butterfly but I could be wrong if I donít increase the amount of air going in itís probably pointless fitting the other parts to gain power so I was wondering has anyone played around with trying to fit a bigger aftermarket throttle body or I could fit a 180 manifold and modify the throttle so it is cable operated. Itís just an idea at the moment but I thought I would post it on here to get some feedback and your thoughts would be appreciated.

    It needs more cam timing, not air or exhaust flow.

    I've read that the 180 exhaust manifold interferes with the 138's lever-based gear shift mechanism (the 180 uses cables, not rods).
