Re: [mk2-16v] how do i find out what engine i have?

[Steven Arguello]

My 88 GTi came with a 9A 2.0, and the guy who sold it to me never knew it. I 
realized it was a 2.0 when I discovered a second knock sensor above the oil 
cooler, the 1.8 only has one.

Good point Steve. There are a bunch of other ways to tell, but they are far
too numerous for me to type on a phone.

Re: [mk2-16v] how do i find out what engine i have?

[Holland Phillips]

Does it have a ECU mounted under the plastic tray at the base of the
windshield?  The tray covers the windshield wiper motor, and is held on by
some clips. If it does, it's probably a 9A. The 1.8 liter 16V doesn't
utilize an ECU.

Re: [mk2-16v] how do i find out what engine i have?

[Holland Phillips]

Well, it's definitely a 9A engine. Whatever else is going on with the internals is a mystery. I would just buy all the replacement parts you need for the 9A and be done with it.

Re: [mk2-16v] how do i find out what engine i have?

[damac2004]

1.  yes there is an ecu and it has a techtronics chip in it that says 16v 
2.0

2.  i think it does have 2 knock sensors on the front of the block to the 
left of the block breather fitting?  each one looks the same, one has a 
bare wire the whole length, and each goes to its own wire harness clip.

3.  this car is disabled on the driveway and im struggling to get it higher 
for me to get underneath.  i was trying to feel around back there from 
underneath looking up and all i can find on the drivers side lower block is 
a big embossed A

i'm new to these cars so im scared its some kind of other engine.  this 
still doesn't explain how this car was using the larger im shaft and 
smaller oil pump gear?  there isn't a mark anywhere on those parts so 
obviously they aren't hitting the guts of the engine.

I don't recall you saying what year your car is. If it's a '91-'92 2.0
liter 16V, the engine designation is 9A.
