Hi all im new to this forum and joined as i just got my first subaru its a impreza 2000 awd turbo x reg with prodrive pack my qeustion is im thinking of getting a manual boost controller and boost gauge what psi can i increase to without harming engine sorry if i seem like i dont know what i talking about as this is my first turbo lol, any advice on cheap mods to gain more bhp welcome thanks

 

The boost has already been raised over standard as it has the ppp, you might be able to get a little more from it, but this will effect the fuelling, and should really be avoided.... unless you have things to monitor such things......

 

hi yes but i not sure if it was made with the prodrive bits or someone put them on it has prodrive exhaust,suspention,brakes,few hoses,thats about it i think so not sure dont know much about these cars as this is my first thanks for reply

 

Pretty sure no impreza were made with the PPP as standard but were an optional extra (you paid more) so were put on after the car was made.

Checking that the car is fine first (a rolling road session is a good way to find if the boost/fuelling is fine) would be a good start before you start raising boost.

 

thanks mate will get it on 1 as soon as i can cheers

 

had it rolling road today boost and fueling fine boost running at 0.5 bar and 215.3hp man said it hasnt been tweaked but i cant increase boost without getting stand alone ecu and remap at a cost of £1000 is this true as i fort you could increase it to about 0.9 to 1bar without that mapped advice pls

 

0.5 bar isn't the right boost level in the first place for your car it should be 0.9bar as standard.
Whoever told you to spend £1000 is taking the **** as you have a problem with your boost although 215bhp is standard for your year car.
I wopuld take it to someone who knows a lttle bit more then the people you took it to (were they trying to sell you an ecu upgrade?)
There are plenty of DECENT specialists out there do a quick search on here for recommendations.
