RX8 ENGINE CONVERSION

I'm sure there are a few LS1's & I think there was one in the UK with a Nissan S14 (or something like that) turbo lump.
Broken ones are falling into the sub £1k price range atm, so could be a good base for a project.

LS1:

Why not a 13B?

or stick with a wankel

in an RX4

RX4 on track


supercharged LS1 would probably be cheaper though

A lot of RX-8s have "broken" engines that aren't actually broken at all. They often fall prey to the triple-pronged attack of RX-8 shoddy component quality that makes them seem very dead when in fact they can be resurrected for cheaps... that is; coil packs, collapsed cats and/or flooding. Any one of these can be easily rectified and you can get a perfectly good and ridiculously cheap 20-grand car. It helps that a lot of owners wouldn't know a dipstick from a rampant rabbit. Mind you, the build quality on a lot of the car isn't good since they're essentially Fords, and I fear they are not destined for classic iconic status...

Handle very well though, stiff chassis due to all the bracing for the funky doors, and extremely high level of trim and equipment for your money.

No, they're no more difficult to work on than a piston engine, arguably easier in some ways. Tuning them is perhaps more of a black art due to the lack of easily-available information and is usually the result of hard-won knowledge gained through zen master-like contemplation and bitter trial and error. People who've earned such knowledge tend to guard it jealously. To build one... anyone can do it. To build one well... not so easy.

Tips used to wear badly on older rotaries, especially the NSU and Citroen designs where they used very hard apex seals. Mazda ones are a lot easier on the housings, though eventually they will wear. Apex seal failure more usually tends to happen catastrophically from detonation. Rotaries can't take knock at all, it finds the easiest route out and that's usually the apex seal. The being ruined by turning the wrong way is an urban legend from heavily tuned (ie ported) where the intake ports have been opened up to the point that if the rotor runs the opposite way the seals can intrude into the port and wreak havoc.

That is all

I was quoted £1509 inc for rebuild kit for rx7 rotary engine!! That was to diy!
Scrapped it instead

A master rebuild kit is only £868 ($1340) and includes all apex, side, corner seals and 'o' rings.

Best idea is to strip it and then see what is worn and it'll work out even cheaper.

Atkins sell a rebuild video that takes you through it. Doesn't look too hard at all.
