Hey mate, 31s should fit with the stock suspension setup. Had them on both my previous and current R50s. Looks like the Regulus you're looking at has 16" rims so you'll need to get the equivalent of 31s as they're only available for 15" rims. In terms of suspension changes between models, I think they only change between the 96-99 and 00-04 was the orientation of the rear shock mount. The others will correct me if I'm wrong though.

Finally got some recreational miles this week. Climbing Browns Camp and camping at Whalers rest.

265/70r16 is the perfect size for the 16" wheels. I would recommend getting the QD32 over the TD27, more power and better economy as the gearing is better on the open road. Loved my old r50. Stay away from the petrol versions, the QD32 has nearly as much power and way more torque. Check the intake hose from the airbox to the turbo isn't cracked, mine was. $60 off trademe for a new one. Also look for one that's had the electronically controlled injector pump rebuilt if you can Stay away from any that jerk taking off from a stop as this can indicate the injector pump is on the way out. This doesn't apply to the wd21 as it has a mechanical injector pump.

Completely different and impractical to adapt suspension parts from a Titan to your WD21. Same with later Frontiers, Xterras, and Pathfinders. When they did away with the torsion bars, everything got redesigned and is completely different.
