dont know whether its a common problem but i get a huge boost surge to around 20-22psi sometimes, but most of the time the car hits top boost at about 14 psi :S dont know its fell out of tune or the actuator is seen its day, any help appreciated

 

Have you checked the timing?

did the cambelt on it and checked the timing but it still it had the surge, then renewed the cam and followers, re-checked the timing and still had the issue. Im gettin an ecu with an ahmed bayjoo chip on it so ill get the 31 actuator and then see whether its the actuator.

 

are you sure its not just a boost spike? when mine initaly comes on boost it peaks at about 18 ish then drops and holds at 14ish and does this with every gear change when your giving it beans. but if your not proper beaning it. it dosent spike just pulls 14 and holds.

 

does sometimes, but doesnt spike every gear. I had a 22psi gauge in and it maxed it out :S so last thing i want is the engine to go pop lol

 

i have a standard rs engine running 18-20psi all day long and so far its been reliable

 

if your in doubt m8 youll just have to get it checked

 

check the dizzy they have a tendicy to go tits up

 

i'd be putting money on actuator spring getting hot and going weak, retarded timing could cause a surge though.
