"lexmaul jobby with some piper cams and pulley"
this is kind of against the point with the cams and lexmaul. the lexmaul makes the least powerful gains of all the aftermarket inlets, but can do without needing a trip to the dyno and programable ECU, but the cams will only benefit from the new management, depending on the degree of them.
Most performance will be Throttle Bodies, but will be most expensive. Can see the good side of 180bhp for a few grand. You also need to look at internal engine strengthening, standalone management, new brakes.
Mantzel properly setup with new pulleys and cams will see 140bhp, along with the usual mods like filters and exhaust.
Throttle Bodies would be the way to go if i was you, very reliable when looked after, and possibilty of better MPG when driving sensibly. Reliability shouldnt be an issue with any of the above ideas, as long as you keep engine looked after with frequent oil changes etc

before you get carried away fitting cams, remember you cant dial them in with verniers unless you run new management
