Manual Boost Controller

[RPS13X]

Hi everyone i'm new to the forums and I have just recently bought a 1989 180SX turbo. I have just put a manual boost controller and am now running about 11-12 PSI but for some reason I can't rev past 4000 RPM. If anyone has encountered this or know how to fix this please let me know. Thanks

has the car always done this?do you have a catalitic converter?if it is a new situation did the car do anything when it started, noise, smell, weird cage reading, start smoking etc.

yeah i have to say that adding a non-electronic device seems unrelated to your revving problem?

perhaps during installation you unhooked wiring, diconnected something? idk

your not hitting boost cut???

i thought you couldnt boost past 6 without any fuel upgrades?

i wouldnt believe that true. stock is 7psi. and i was boosting 9psi on stock everything and ran fine. at 10 however it would stutter. but currently its going thru the process of the upgrades in my sig.

where are you getting your manifold from?

[WeldingHank]

sounds like your hitting boost cut to me.

this guy from fresh alloy is parting out his stuff. it looks like the one off of ebay, but according to him it isnt made of that material. i hear the ones off ebay tend to crack but its used, so i can hopefully trust it.

do you have the stock CA fuel pump or a KA one? i had a KA24de could i run more than 7 psi with it safely?

i run 1.0 bar with no problem on my ca .. but not everyday. I never got any boost cut situation

i was using a stock KA24E one. Now im using the walrbo 255.
