Welcome (Y). It all depends on whether your engine is MA10 or CG10. I'm sure you'll find all the tips you need to tune on here, whatever engine it is :grinning:. I'll make a few suggestions to start off with (from my own K11 with a CG10 engine) - cone air filter (K&N preferably), cold air feed, 4-1 or 4-2-1 decat manifold, decat pipe for the second cat, aftermarket backbox (Sportex, Ashley, or similar), heat-wrapped manifold, iridium spark plugs, NGK HT leads, 1.3 cams, skimmed head, and (if your car has it), remove the aircon :grinning:.
Something like this maybe?
:grinning:
I'd recommend lowering and alloys with wider tyres as well (Y)
There is a hell of a lot you can do to these engines - turbo, convert them to run on bike carbs or Webers, drop a CG13 in there, the list is endless :laugh:
