    1.8 Sport, any engine mods?

    as above title, have a 1.8 sport, the looks on the outside are almost complete, but would like to know if its possible to enhance the 1.8 engine to be more responsive and a wee tad fatser etc.

    can't afford top end engine just now or car.


    any ideas?

    Replace it, as standard manifolds in general are restrictive, make the gasses more free to flow and such mate

    Imo the money you'd spend trying to increase the bhp, i'd put to one side and save for a nice z20let seen a few go for a grand now, and thats what u'd pay for cams manifold and remap if not more.

    But like i said that my own opinion. All i've done to my 1.8 cab is de-restrict the airbox added a courtney panel air filter veccy c mod and added the remus centre pipe and irmy back box.
    Lowerd,tints, irmscher grill, irmscher back box and remus cs, courtney panel filter, veccy c mod, deristricted airbox
