Not mine, looks like a familiar 1000 that was on datsun1200.com being converted to a ca18det. The sr20de will not fit or it would be in the engine bay, either way no reason why this ca18det setup was ever run, me thinks it was sold separate or for other project never finished looking at the cut up front butchery.
 
so heads up the sr20 on the side which is now included with the sale but has not been test fitted or does not fit without major sump and other changes. So buyer here should consider just shell for $400 to $600 only depending on parts and if seller kept the metal he cut off the front.
