All depends what you want it for!!
I had a '97 2.5 non turbo medium wheel base high roof, fantastic around town, handled like a car, could throw it around roundabouts and in and out of parking places. Slow for motorways, would struggle up a long incline, losing speed all the way. Overtaking had to be planned well in advance. And that was empty!!
Now I run a '01 2.8jtd maxi. Tonnes of power, overtakes no problem, foot down and away you go, can accelerate up the same inclines the 2.5 struggled with. At 4.30am with no load and a clear motorway have seen just under 100mph. But doesn't handle as well as the mwb the extra 60cm lengh makes a big difference.
Avoid the 2.8 non turbo, eats gearboxes and very difficult to find a replacement as is specific to that engine.
For fun, I'd go for a short low roof with a 2.8 turbo and start racing young lads in pimped micras!!
Keep well,
Torq
