Ive been wondering for too long now about how a turbo EA82 seems to run quite well before any boost comes on.


This sort of leads to thinking how a turbo block or pistons anyway would run in NA form.


Ford once gave us optional low compression I6 engines, only ever seen one so could not have been much sought after, but they were suitable for lower octane  fuel.


Has anyone decommisioned the turbo on an EA82T and ran it NA ?

I might try it.
A friend has a EA-82T turbo motor he'll let go of for $100, he says fuel injection system has a problem and he also doesn't have an ECU for it. Thought of buying it for parts, but a non-turbo NA build with a custom homemade intake manifold and carb might be fun.
Anyone have an opinion?

    If it ain't broke, you're not trying.

The cam cut is different in turbos as is the timing curve. This difference gives it a little more oomf on the bottom end until the turbo spools up. No turbo, no mid or upper range power. It's a dog. Stay away from hills. lol
