I have one, awesome car blown a rotor cost £800 for a new kit to repair it
luckily I've rebuilt a few so don't need to spent another £1000 getting it fixed that's only if you can find someone to fix it! Most will let go of their guts at around 60000miles because the owners don't realise how much you have to look after them neglected oil changed and or checking the oil level results in knackard tips! Watch out for cars that start fine from cold but not when hot! This means it's fubard and needs a rebuild! I laugh hard when I read the lies that some sellers spout on eBay, my favourite was that it's a well known ecu fault hahaha, some idiot then paid him nearly 2 grand!!! I wouldn't pay over a grand for one with hot start failure!
Make sure you find a Mazda technician or buy yourself a hot start compression tester for a 13b, they ain't cheap but looking at the cost of a rebuild they can save you allot of heart ache! I can't stress this one point enough
GET A HOT COMPRESSION TEST BEFORE BUYING
Get the seller to meet at a local mazda dealers and arrange for them to test it
If you need any more help or advice give me a pm, I've got first hand experience with the bstards lol
By the way the word fuel economy doesn't exist with these, you'll be lucky to hit 18 mpg on the motorway less in town, not to mention the oil they consume, rotary engines spray oil into the combustion chamber it's normal to have high consumption but just adds to the expense
It sounds like I'm scaring you but I'm making it as real as I can for you, expect to spend allot of money running it and allot of time looking after it, they're like a baby and cannot be neglected, if you it'll just be another one of the hundreds on eBay being sold by dreamers who think they're getting a bargain
650cc per rotor, twin rotor engine 1300cc, the tax on the pre 2006 model is 200ish a year the tax 2006 onward is 400ish a year bear that in mind when buying, the tax is the same bracket as a big engine car because it is a big engine but compact if that makes sense?? It burns nearly twice as much fuel as a stock skyline, rotaries can't be compared on engine size to a piston engine as they are both chalk and cheese
It's classed as a 2600cc because of the CO content I believe, and the older na fc rx7 is classed as a 1300cc for some reason well mine was anyway but the turbo fc and fd are classed as a 2600cc for racing reasons something todo with the volumetric efficiency someone with a bit more knowledge of the racing rules will correct me
