I want to know around how many miles the FD's engine will go if I do the reliability mods and keep the engine from overheating, new radiator, and maybe intercooler.

 

I have 100,000 miles and its running strong at 100% stock. I've read posts with 150,000 miles. You gotta be careful.

 

I've got 93K on my original engine and it still seems to run fine.

 

I just bought mine recently and it currently has 94k on it. The engine and turbos seem to run in perfect condition compared to my last FD.i'm hoping that this engine will last me a while so i can do some mods with it.
