hi ppl, have an issue with my boost at the moment.
when the car is hot the boost is very weak only .5psi and.7psi after 5000rpm.
and for some reason it just feels weak. as if there is hardly any boost
I think its the actuator which is acting up. but does anyone think its down to a lack of cold air through the induction kit


I have a new manifold and induction kit onthe car, i might of damaged the actuator when i had the turbo out.

Sorry I only know a little about s15's and never heard of a boost solinoid?, i probably know what it is to see it but not what its called, where would i find it on the car?

I have perfect boost and power for a few minutes when i start driving but as soon as it warms up power reduces

i seem to be getting a lot of oil spray out of the dump valve also? any ideas

im getting a lend of a mini vac during the week to see if the actuator is stuffed

does anyone know if the actuator works from vaccum or preasure?

its a right little head wrecker this one

I have just fitted a japspeed manifold and a blits sus induction, but i dont think these have anything to do with it. Oh and the release bearing is going on the clutch

Luck isnt on my side lately hahaha

any help is always welcomed and appreciated guys :)

No I solved that problem with the gasket and new manifold, no exhaust leak anywhere :)

Think i have the problem solved, it is the turbo seals. thats why im getting oil spray out of the Blow off valve

would anyone have a different opinion?
