I've had my MY04 STi PPP for a while now and its everything I hoped it would be.... However..... The idea of a few more horses is right up my street.

Trouble is, how much and how far to go???

Its still under warranty for 18 months and I don't wanna do anything to invalidate it.

Any suggestions welcome

An idea of power/torque and cost would be nice too

Cheers
Rob

 

erm....limited then to......nothing

 

any mods will invalidate the warranty.

to hell with the warranty & uneash those horses.

 

Ahh damn it.

I thought that certain conversions like tsl333 etc could be done, guess not.

Cheers anyway

 

You could always keep the number of horses but tame them a little more. Some choice suspension and brake upgrades can often reap much more reward on the road than power increases, and for a much lower premium usually

 

Yup get the prodrive spring kit fitted then some kinda big brake kit, even a bov does away with warrenty so i hear.
