external wastegate problem

just had a new td04 kit fitted i used to have one with an actuator and dumpvalve but the new kit is externally gated

does the external wastegate replace the actuator and dumpvalve wasnt sure if it did?

basically left the garage driving home and the boost controller isnt stopping the boost as it should it just keeps going up and up i have to stop accelerating before it blows my engine up

just wondering if any of the vacuum hoses are muddled up or anything? from what i can see there are 3 one goes to the turbo the other 2 to the external wastegate 1 to top of it and 1 to bottom

im just trying to get photobucket to work at the mo to get some pics up but can any1 think of what this could be so far until i upload some pics?

if your worried you can just connect the bottom port of the waste gate straight to the turbo, should run spring pressure

right then finally got the pics to work im working from left to right, i could be wrong but the 1st pipe goes from boost controller solonoid to bottom of wastegate

2nd one from other side of boost controller solonoid to the turbo

3rd one from around the inlet manifold (not sure what part it goes to) to top of wastegate

could the 2pipes that go to the solonoid need switching round is there a certain flow direction for the solonoid?

same watsgate as me by the looks of it.

what boost controller do you have? i would recomend leaving the top wastegate port open and going for a drive to see what base boost pressure is. as long as the side/ottom port has a vacuum feed from somewhere (the turbo is fine as that looks like what you've done)

boost controller is a blitz dual sbc it has 4 settings on it not been altered for over a year now i even turned it down to the lowest setting which is about 9psi to see if it stops at that instead of waiting for it to go over the 15psi which is the top setting as thats a bit risky while i get it sorted

what do you think the problem is then im confused

it will be down to your vacume lines or boost controller setup.

does your boost controlesolinoid have 3 or 2 ports?

solonoid has 2ports

if i take the pipe off of the top wastegate port where do i connect that too then or do i just leave it dangling somewhere?

right, bottom port to the turbo nipple, top port to your OUT port on the solonoid, IN port on the solonoid to a non vacuum boost source, so you can T into the turbo nipple feed to the bottom port of the wastegate if need be. Plus you need to set your EBC to work with an external wastegate if you have been running a stock actuator before.

that should sort it mate :)
