You want more power from your peugeot 106 xn you have an induction kit what else can you do?
Install a v10 viper engine in the boot,
would be a sweet project but expensive!
try upgrading the exhaust system, a straight through from the
cat would help airflow, you could also consider getting a de-cat
pipe. this would probably see an increase of 4-7bhp depending on
the model, be carefull though as removing the cat will make you car
illegal!
taking out the back seats will see you off the line a bit
quicker, although this is the only single advantage of doing
this.
after that you should probably sort sum new stiffer springs/or a
whole new suspension kit. some wider wheels will see you stick to
the road round the corners better.
then maybe some uprated cams, an engine remap, bigger brakes.
hope you have some cash!!!!
