Im so going to get flammed 
I have the original heart to my Coupe (140K F22A1) as of right now, its just sitting here rusting away. Really its sad.
The egr valve is on my 90 4 door, so the cyl #4 is full of water for atleast a few months.
My tarp apparently ripped
ddcb7 had his H22A4 shred his timeing belt at like 6K and well, we assume the head is toast.
Now is it pretty much the same as the F23/22 with H22 head except reversed?
So far Im thinking....
Press out the H22's water pump sprocket and replace it with the F22's
Swap the F22 crankshaft sproket onto the H22
Use existing H22 tensioning systems, use F22 timing belt
H22 lower timing cover, F22 upper
F22 Headgasket
Use the OEM knock sensor with a P14
What should we do about the oil regulator on the top of the block?
The H22 does without it, but the F22 has it and it drops right in.
Now as you know this is not smog legal, but if the A4 is from 1997 I've heard the bearings are 50mm instead of 55.
So what that would mean, is that we can swap the H22 internals into my old F22, then not mess with the tensioning or water pump.
Then the motor retains the stock "look" however, its much more
But after remembering the 85mm bore, im pretty much limited to F20B pistons, or pricey cutom pistons.
So what you guys think?
Flame on lol
