separate turbo hot side

[JP_McCann]

I need the hot side machined. they don't want the whole turbo, just the hot side. What is the best way to separate the hot side? do i just need to use an open end wrench? what size is it?

[JP_McCann]

and one bolt snaped off. now what?

[JP_McCann]

just having where the turbine housing and the exhaust manifold meet machined flat.


What is the best way to remove the bolts that hit the CHRA?

[JP_McCann]

Loosen all of them a turn or so. Get the CHRA to rotate in the turbine housing. Take out the bolts that do not have any interference. Rotate the CHRA to where the ones that have interference don't. Remove those. Lather, rinse, repeat.

I can't get them to loosen a little bit. when i put an open end wrench on it doesn't hold and just slips and rounds the bolt a little

I think I snapped half of them when removing the housing. I had them machined and new bolts installed.

I soaked them in Liquid Wrench and had some success. I've seen heat used too. Either way, I'd plan on new bolts all around.

[JP_McCann]

got all the bolts loose. how to i rotate the CHRA? I can't get it to turn at all. what is the best way to pry it out also. Iam pissed that i didn't use heat on the elbow side. Jut tried pb blaster and then snapped all the bolts out. Heat on the turbo side and they all loosened.

PS where do i get new bolts? Torque spec for them?

[JP_McCann]

So the turbo is all machined and the bolts removed. They helicoiled one bolt. Where do I get replacement bolts? Is there a torque specs for the elbow or the turbo side? Any other suggestions?

[JP_McCann]

Had the machining done at fleet pride so not sure if they would have bolts. Anywhere else to get bolts from? The helicoil is on the elbow side but I would need to check what bolt exactly.

[JP_McCann]

Call Charlie at Evergreen. Or Harry at Precision Turbo & Engine.

so not something that i can go buy in a store

[JP_McCann]

What about 10.9 or 12.9 or ARP stainless?

[JP_McCann]

the only reason i am saying this is when i called charlie he said go to the harware store and get grade 12 bolts. i will call him again and see what he says

[JP_McCann]

i don't see just the bolts on their websites. Where can i buy copper anti-seize? Charlie also said to use a little ultra copper silicon on the elbow side. If i shouldn't use 12.9 why would charlie say to? what anti-seize should be used on the turbo studs and the manifold bolts?

[JP_McCann]

think i ordered it got 5 bolts and the clamp set. they guy i talked to thought that they were the hi temp bolts. I guess this will get back together next week. Would any store sell the anti seize or will it also need to be ordered off the internet?

hey mike would you reccomend against putting it together with 12.9 for time being and replacing it when the new stuff comes in?

Charlie told me to use the 12.9 on the outlet elbow and it has been 2 years with no problems so far!
