I can't find 'em anywhere on here. Anybody got a link? Help a fella out. Thanks
You want to gut it Scott?
yeah. Butterfly valve (& the shaft) & the pedistal mod too. Putting a Dominator 66 on today & want unrestricted flow on the exhaust side. I sent you a PM to the same effect. Thanks
I will assume youre going to remove turbo from engine then.
You can see the butterfly housing (upside down in this pic) unbolted from the turbo here. Unhook the actuator arm, take a die grinder and grind off the two rivets that hold the butterfly to the shaft. Drive the shaft out of the housing and get two 3/4 inch freeze plugs to drive in the holes where the shaft was. Just that simple, valve is no longer a restriction.
In this picture you can see the pedestal unbolted off the bottom of the turbo, on the back side of the actuator there will be a snap ring, remove it and pull the back cap off of the actuator and pull the valve out of the barrel. Flip the pedestal over, drill and tap the arm exit hole for a 1/4 inch pipe plug. Insert pipe plug and reassemble everything. Enjoy your new found unrestricted exhaust.
Here is a link to an article on turbo removal. Turbo Removal WIKI
Mine is tied open with a piece of wire but there is a very tiny oil drip coming from where the rod connects to the turbo. Not a big drip but should I be concerned? Will it damage anything if I do nothing?
Its going to make an oil slick in the valley and it will get worse, eventually it will begin to run down the back of the block and she'll mark her spot but other than that you shouldn't see any physical or mechanical harm come of it Richard.
Thanks for the info Mike...
I need to replace my up pipe donuts and thought about doing the ebpv delete as well...
Do I need to remove the turbo, to change the donuts?
Sorry for that last question being a hijack...
Hijack off now!
