<< Hello ,
Can you tell me how much it would cost to increase the horse power on my 05 WRX Impreza .
The sort of power gain I would like is about 40-50 hp .
Thankyou >>
Its not all about the bhp... need to consider the torque as well !..
I have fitted a full decat exhaust system, equal length headers, HKS induction, Uprated walbro fuel pump, FSE power boost valve, 550cc injectors and an Apexi Power FC ecu. Some of the parts were second hand but the last 4 items are brand new. Cost for parts approx £2k plus fitting (approx a days labour) and Jolly green monster to Map/setup the ecu to my modifications was addtional....
A lot of these bits are over the top, but I have gained nearly 50bhp so far but I have plans for an additional 50-60 bhp once i purchase a turbo and intercooler.
Prices will be the same if not slighty higher for an 03 wrx
Over to you Simon
