I have a light illuminated on my dash and i am told it's the self levelling hid head lights any idea how to fix this and what things to do to modify the engine not majorly but to get about 260/280 bhp out of it and where in essex to get these parts from and rough costs pls

 

Plenty of threads on here with info for you. A quick search will yield lots ( with many options)

In short: remap! High flow cat/ remove some/ all cats. STi top mount intercooler. You'll hit 280 in a heart beat and probably help you're engine by running it a little richer to avoid the famous 2.5 problems!

 

272ish bhp 350lb
Replacement Air filter
Scorpion De-resonator pipe and Prodrive Back Box
Remap

 

or get it it rebuilt and go mad, mines 400+ now lol

 

check each sensor on the axles, the front sensor is common to have water corrode the connection, theyre 250+ vat from main deal get from a breaker
