i just put a big 16g turbo on my d16 civic and i have everything hooked up right in terms of the boost controler and boost gauge but im getting no boost, no leaks of any kind on the charge piping or manifold gaskets are all new...the car still runs fine but there is just no boost, need some kinda help we cant figure it out

 

well the wastegate is internal and it works fine, when i put the turbo in last night we had boost, but the controller wasnt hooked up right so it was spiking to like 15psi i parked it and worked all day and fixed the controller so i was actually hooked to a vacuum line like it shoulda been and now we have no boost. i even hooked the wastegate straight to a vacuum line to get just stock boost or whatever and still got nothing....there isnt really much in terms for a downpipe it kinda just dumps under the oil pan for right now, i know dsm turbos need back pressure but it should still be spooling?! should it not?

 

nope, and nothing has gone wrong, there was boost...than there wasnt

 

did u have oil lines connected

 

ya oil lines are good, i used a stealth mode kit that fit great

 

I would check your charge piping connectors for any holes because i had a connector near metal and it blew it out and the hole was facing the grouns and i couldnt see it i had to feel for it.

 

haha stealthmode kit that fits great...hahahaha good one...you're a funny guy. (just joshin you stevie)

those dsm internal wastegates have the habit of sticking open, smack the flapper arm with a hammer and make sure its closed all the way. the spikes probably fucked it around like a virgin and stiuck it open. its most likely that.

two reasons you would suddenly not build boost anymore... 1st is wastegate open, 2nd is a compressor side boost leak. (popped charge pipe, leaky bov, torn coupler) make sure you check your pipes and stuff too, those high boost spikes coulda popped a pipe.

 

yea im stupid, went out to the car this morning, felt the wastegate flapper arm and it was disconnected from the dowel on the flap
forgot a cotter pin on the dowel

back to boost

will post pics soon keep an eye out
