wastegate question

racerwad · 04-18-2002, 08:13 PM

i just picked up an IHI turbo from a junkyard and it comes with an integral wastegate. i want to get a remote wastegate, ala tial or deltagate. in order to disable the integral wastegate, all i need to do is remove the actuator, or simply not hook it up to any boost source, right?

also, how can i tell which are the oil supply/drain lines and which are the water supply/drain lines? thanks.

If you remove the wastegate you have to weld the door shut. but you can bypass it by just not letting the vacum lines run to it.

Oil lines come in the top and exit straight down out of the bottom.

Water lines are on the side. Doesn't matter which way the water goes.

could i simply bypass the valve altogether and forget about it?

also, i know that the oil goes top to bottom; the thing is, this is in the context of its installation, and that depends on the application. how can i tell by look at the inlets/outlets? i'm fairly certain i know which are which. i guess i could take it all apart and try and figure it out that way. thanks for the help guys.

for mine oil inlet you have to bolt the oil line. For the outlet, there is a flange (for lack of a better term) that you would attach the oil drain line to (like you would a water line).
For the wastegate, I would just not plug it into anything. If you put a cap over the end, won't it (by itself at leased) make as much boost as the turbo can?
