What MK s12 do I have?

[s12reamer]

so an MKII wing would be ideal if possible, but the MKI is not impossible to fit either just a little more tidying required.

Mechanically how do they differ? Gearbox? Engine? Mounting points?

Is there any newer nissan engines that would bolt straight in? Or would I need a mount kit?

Thanks for your reply

Mk1 has a different gearbox and prop. Smaller bumpers and flatter bonnet.

The turbo oil feed is taken from a different place.

The S13 200sx engine is a direct replacement.
