Yes the lightweight is already a 2.25 petrol, five bearing and standard as far as i can tell. The gearbox is standard with both 4 wheel drive and low ratio levers. I'm not getting the box from the 90 since that is a permanent four wheel drive. I believe that the engine is a 2.25 although one of the responses I've got says that the 90's all had the 2.5. I'll try and find out from the guy who's selling it exactly what it is.
