ok that's great news cheers.
Regardless of which conversion is better, who's are the cheapest subframes or are they much of a muchness?
It really depends how much work you want / can do yourself, with allspeed theres not much in it as you say, but good thing with allspeed is that they basically make the lot, subframe, driveshafts, etc. There are also a few guys about on facebook that can build you a vtec or rover k series frame. If you can build a subframe yourself you'll save loads, with each conversion there will be fabrication involved, bulkhead mods, driveshafts, engine mounts. Most conversions will need inner wings removed and a flip front too
Micra: Cheap, lots available, not many body mods, 5 gears, fit under roundnose easy, not the most powerful
Vtec: More expensive, can require body mods, more power, tight under roundnose
Rover: Cheapish, different engine choice, can require body mods, good power, tight under roundnose
