But in how long have you spent 13k? Its not much over the years, but as a lump sum its huge, and 20k is even more.

But you could get an S13 200SX and have that running with a modded 300ZX engine, and decent suspension and brakes for less than half that.

And itd look better, and almost deffo handle and stop better, unless it was a top notch job done on the Micrap, as most mis-matched engine transplants like this make for wank cars overall.

Or just buy an engineless 300ZX to put the lump in, for 20k you could make one miles quicker than a 20k 300ZX micra would be.

Or sell the lump and just do summat else that involves a better engine.
