i have a ej20 turbo 4cams from '93. can i change the heads with the ej25 4cams head fiom 98?

What is the result?

They'll bolt on....however I can't tell you whether the intake manifold will have some issues aligning properly, or if the coolant passages and other stuff will be exactly the same.

 

Also....the turbo heads will have a line for oil to feed the turbo...the n/a heads won't.

 

I'd probably pass on swapping.

 

Why are you looking to do this?
