i jsut recently turbod my 91 ka24de. and when i ran it the otehr day it didnt run correctly at all..the car had no power what so ever at any rpm. the b.o.v wouldnt of off when i came off the gas but it would go crazy around like 5,000 rpm. the turbo soundedlike a horn when accelorating i think the waste gate was stuck open im not sure the waste gate isnt ran back into the downpipe at the moment. the turbo kept blowing the filter off & then pullin the car bak into the shop the turbo blew. im not sure if my vacum lines are correct or what the turbo was sent out yesterday to be rebuilt a brand new to4e turbo. some one please help me. im planning on runnin a boost controller when the turbo comes back and im not 100% sure on how to run the vacume lines

you basically need 2 vacuum lines extra for your turbo set-up...

1 goes from the intake plenum to the BOV
2 goes from the turbine housing or the charged pipe to the wastegate vac nipple

you don't have to recirc your wastegate... i'm running open gate right now too
and the turbo was blowing your filter off?? wtf? you have something set-up completely wrong

*NemeGuero* · 10-13-2005, 06:39 PM

re-reading... are you sure you have the spring in your wastegate?

nevaland9 · 10-13-2005, 09:18 PM

it wasnt gettin blown off i guess it kept fallin off it was some cheap blbble filer that is held on with 1 screw in hte center...so running a manual boost controller & external waste gate where do i run the vacum lines to? and what about the blow off valve? i know how stupid i sound im 17 nd im just tryin 2 get this to work..the turbo blew up because i think when the filter came off something came in because the fins were damaged

*NemeGuero* · 10-13-2005, 10:13 PM

sounds like it. Ok, look at your intake manifold and you'll see rubber vacuum lines (kinda small) coming off of it. Go down to the store and get a T-fitting that will fit inside and put on an extra vacuum line. The other end of that one goes to the top part of the blow off valve.
Now, your charged pipe is the one right after the turbo compressor (the front part of the turbo.) there should be a vacuum nipple there, or on the turbo housing itself. Now, the other end of that vacuum line (the charged pipe nipple or turbine housing nipple) goes to the wastegate vacuum nipple.

Your boost controller goes on the last line I described between the wastegate and the charged pipe/turbo housing.

thanks for all your help one more question the vacum line comin from the turbo housing to the waste gate which nippe is it the top one or the side one? and is one of those nipple supposed to be left alone?

*NemeGuero* · 10-15-2005, 09:06 PM

where do you have 2 nipples?? No nipple should be unplugged..

nevaland9 · 10-16-2005, 12:00 AM

on the external waste gate....one on the top and one on the side...u only explained one nippe for the waste gate

*NemeGuero* · 10-16-2005, 12:12 AM

mine only has 1 nipple... hmm... what kind of wastegate are you running? maybe they have info on it on the company's website

nevaland9 · 10-16-2005, 07:09 PM

Waste gate pic .......thats what kinda of waste gate im using

*Jeff240sx* · 10-16-2005, 07:26 PM

Plugs in the side port. Leave the top alone unless you have a boost controller.

nevaland9 · 10-17-2005, 05:07 AM

s4teensylvia · 10-17-2005, 07:18 PM

When using a boost controler if you put the hose on the top do you leave the spring in the wastegate? Or is the spring only if your not using a boost contoler so it opens at the springs rated boost?
