Hi all,

I have always lusted after an RX7 and I think the time has come...

I will need to do about 500 miles a month in the car and IT MUST BE RELIABLE. I have heard all the stories about the rotor tips etc and am looking for some owner feedback...

Stick in 3mm ceramic seals and quit worrying.

Don't forget that Jon uses at least 2 galons per mile on shooting flames out of the exhaust.

If there's something the rex does well it's spitting flames on circuit!

Nice, what kind of bonnet have you got there? Looks subtle, buch nicer than the huge central nostril types!

Flames not so good when you are running the race car up to temp in the garage and nearly set fire to your unsuspecting brothers legs

With the twins running in parallel (like a small, laggy single turbo) it was ~22mpg mixed and 24 motorway.

How do you go about making them run parallel, is it costly 24 mpg sounds ok to me.

[quote=Beefmeister]If you're looking at that car in particular, i'd say it mayneed a rebuild, which is the fat end of £1500, though it depends how the car has been looked after.

I was with RE-Worx a week or so back and they were saying that whilst the base cost for a rebuild is around the £1500 to £2000 in reality they tend to come in closer to £4000 because most of the parts end up only being fit for chucking.

In my own experience when mine went pop, Dragon quoted £2000 for the job but found that due to the nature of the damage it needed new housings, end plates as well as all the usual stuff. Mine came in around £3500. Ross showed me the bits as they came off as well so I could see the damage for myself.

They are, however, a great car, unusual, handle great and are reasonably quick. Down side is they're thirsty and expensive to fix if they go pop...

There's a'how to' on either FDUK or Mazda Rotary Club but it seems a bit complicated to me.

If you talk to Carl Hayward from Hayward rotaries he does a quick mod relatively cheaply to run non sequential or someone like Dragon will to the full monty with welded blanking plates and the lot. Carl will probably do the full monty too - I've just never asked.

When I had mine running like that the only plus point was the predictability of power delivery (compared to the kick from the second turbo coming online in standard trim).

It's incredibly laggy, adds huge heat to the system (compared to equivalent power from a single) and doesn#'t actually give any more power than the twins with the same additional mods...

Talking to Carl and he maintains that it can be done and mapped to give better performance than I experienced though.

And add 1k to the rebuild cost and an extra 1k miles to the running in! Picking mine up tomorrow with these

Not a big fan of the scoot-style bonnets either. Mine's a Pan Speed, pretty subtle and works quite well.
