난이도 & 준비물

증상

After a few years in Subaru’s interspersed with a bmw and a honda Ive scratched an itch thats been with me for 20 years.I was 16 playing 5 a side and another player arrived in his white RX7. I’ve lusted after one ever since. I’ve never been brave enough and never really had the opportunity to own one until now. 18-24 was too expensive on running costs and insurance as I was doing 70 miles a day commute. 24- present day Ive been in company cars and the missus has used whatever the second car is as her daily. Hence the hot hatches and imprezas. Mode of transport for her. Fun weekend car for me.

Clad-Hach said: That's just lovely...nice colour too.I know nothing about rotary engines, is there plenty of specialists around to take care of them, and has the weak points been ironed out over the years to give them better reliability.When I was growing up I remember a guy in our village running around in a strange looking car which had a different sound to all other cars, it was an NSU Ro 80.As usual the internet blows stuff out of proportion. Apparently the 13b in this is a hand grenade with the pin pulled. In reality they are quite robust. I will caveat that with if you look after them properly. Treat them like a 4 banger in your golf and your in for a bad time. They don’t like being started and stopped when cold. They flood the engine. So shunting about a driveway is bad. Oil consumption. They use oil by design. There’s an oil injection pump which injects oil from the sump into the combustion chamber to lubricate the apex seals. Because of this 10w40 mineral oil or semi synthetic is recommended and is dirt cheap. Change every 3k miles as fuel dilution is a thing on these. No point in running £80 fully synth it causes ash buildup as the additives don't burn clean. The engines don’t tend to let go in a big way like lets say a piston engine throwing a rod. They just ware out and give ooor compression results leading to poor starting. Healthy engines are in the high 7s and 8 bar. Mine was tested last year by the previous owner and was high 7s bordering on 8 on both front and rear rotor. Anything starting with a 5 is tired and just about ready for a refresh. This leads me on to the cost of a refresh. It’s cheap compared to a piston engine. 8-10k wasn’t unreasonable for a nicely built impreza engine without going nuts. It’s give or take 3k for one of these (assuming your rotors and housings are good). They have a lot going on in the engine bay. The twin turbo sequential system is complex and constantly being cooked by the engine. They run very hot. Rubber hoses go
