What engine is this?

Hi all,

I'm a newbie here. I've been after a mk1 for a long time, and there's an intriguing add locally to me. Only issue is that the owner doesn't have any information on the engine. The car is originally a 1.8 GTI, but can anyone let me know what engine is in it?

Cheers, any help appreciated!

Looks like a 16V from a Mk2 Golf, KR engine code on bike carbs

Perfect, thanks for the info!
