some general questions on the car i will buy

[ditn]

I have some general questions from an ae86 i will get next week:

*The engine in the car was not black blue i expected it to be but it was red & black with tvis.
As far as i know this was never in an ae86 and i cant find alot of information about it.Is this a bigport redtop then?
The power is rated at 91kw on the papers

*The grill on the front of the car looked different and had yamaha? written on it like this:

I can't remember it ever coming with a grill like this,anyone know from where te grill comes?(im guessing it is to let more air come into the bay but why is yamaha written on it)
here another example,beginning video
