the 1.8 is in, couple of things I have found:
the TPS on a 1.8 & 1.6 auto are the same but have different plugs, so I just took the one off my 1.6 and bolted it to the 1.8 TB.
ICV plug is different, on the lookout for one now.
1.8 & 1.6 water temp senders have different plugs, need to buy a 1.6 sender
1.8 & 1.6 starter motors are the same, just the bracing bracket at the back is different but can be switched from one to another
early 1.8 alternators have the same plugs as the 1.6, no need to swap them over (FM say they need to change, this is wrong)
putting a clean engine in is easier than taking a dirty engine out!
things to do:
fit the 320cc injectors (waiting for seals)
fit the exhaust manifold (waiting for gaskets)
finish the wiring
get new drive belts (given the wrong ones by the shop
)
