Surely the easiest way has got to be just swap all ancillaries off the a8 onto the a7 while you rebuild it's then there is no doubting what fits/doesn't fit?

Not sure about intake gasket. What's the actual difference between the 2 (in terms of the mating faces)?
Pics?

H22a or h22a7 or it doesnt matter ???

It doesn't matter.

I did for get about the IACV difference

And didn't know about the water temp difference alough looking at my old pics I can see it

Like Wurly says, swap all the bits from the Type-S engine over to the H22a7 (intake manifold, VTEC solenoid, water temp sensor) and it will work.

I bet they're the same?

Use the type s/5th gen injectors. There is a slight difference.
Atr, 4th and 5th gens injectors are all different.

Atr injectors have a longer nozzle due to longer runner entry.

However with a slight mod they can all work.

The knock sensor on my type S block had a black sensor

The atr engine a green one

Do i need to switch them?
