Here's a tip from Neil who hosts the 4-eyed BBQ in WA every year.

Mix a small amount 1/2 and 1/2 concoction of ATF and acetone. Dab it on and let it soak into the threads for 10-15 minutes. You can heat it up and try removing it again. It may take several tries, but some people swear that it works better than PB Blaster.

Ill give it a try, Thanks

You say you used heat. Did you heat the egr nut until it was glowing orange, then let it cool (breaking loose the rust bond when it expands/contracts)? I typically do that, then if it won't break lose, I get it orange again and try to remove it while hot the second time. Be sure the EGR is unbolted from the intake before attempting to remove it as it's common for the nut to be stuck on the tube and the whole assembly will try to rotate when that's the case. No use trying to break the nut/tube and nut/exhaust manifold bond all at once.

pat , ive heard of doing the same thing with wax, from a candle , get it really hot , and put the candle to the hot nut and let it creap in, doing it several times is a must though

again soon ill see if things work out.

Turbo torch should do it.

Don't loose too much time over it - Forced 4 sells replacement tubes in 304 stainless.

This is EXCELLENT! It will out perform PB blaster & similar store bought products time after time. Just be careful on where you use this mixture since it will eat a hole in asphalt. I generally mix it in an oil squirt can.

Here's my solution, it's not too difficult. After 25 years of hot/cold cycling, the nut is basically welded to the manny. If the other methods don't work, remove the manny altogether. Besides, it's much easier to remove/install a turbo when you remove the manny/turbo as one unit. Remove the tube from the EGR end, pop the valve cover for clearance and you may have to pop the 2 clips that hold the coolant lines together that are behind the block. It depends if your EGR tube runs underneath or over the top of the coolant lines. Disconnect turbo coolant/oil lines, downpipe, etc, remove the manifold bolts and lift up and out fishing the EGR tube out as you go. Once out, chuck the manifold in a vise and now you have total access. At that point, PB Blaster (heat if necessary), pipe wrench and a BFH will remove it in no time. Much easier to remove/install the turbo at the mounting flange too. I've done this a couple of times and it works great!
