The RX7 rebuild thread

Interesting, haven't seen a Wankel in pieces before, nice photos :)

I really like the idea of a rotary engine, very nice and simple.
 
there is a twin turbo rx8 in the states, read an article on it somewhere but cant remember.

and keep it up drex, you will be back on the road in no time. dont slack on any bits tho, better to spend a little and save a lot in the future :)
 
Nice to see an update, you should record your first start up after the rebuild! Would be nice to hear/see it! Nice to see a rotary insides as well, never really seen anything to do with them before!

Looking good fella.

Out of interest what did Mazda do to solve the 60k rebuild problem with the RX8, and has anyone turbocharged that engine yet?

They use ceramic apex seals (rotor tips) on the RX8, apparently good for 100k+ miles. There are a few Turbo'd RX8s about, and some supercharged ones aswell. A friend of mine has the first supercharged RX8 in the UK, but it still has a few teething problems.

Mike306dt: Yeah, I intend to catch the initial start-up on my DV cam :D
 
Looking good and it looks like good (expensive) fun... I want an RX7 now!

What rotor tips will you be using? (uprated?)
 
Thanks mickey, and I'd love to see drexels face when he turns they key and it doesn't start... but only if it's a minor problem or oversight that's easily solved :p.

keep the pics coming.

You can get uprated tips, 3mm as opposed to 2mm, but you have to get the rotors machined to take them, and they can cause problems at high revs. I'll be sticking with 2mm tips, but the kit I'll be getting includes stronger 2mm tips:

Rebuild Kit.

And yes, I will be sharing the vid ;)
 
Wow! You're doing really well mate! Still very gutsy of you to do it! :D

Looks like you've got it well thought out and planned. Look forward to hearing the ongoing progress :)
 
Woah, that's quite a big step up from mecano. :p :D


Good work though, be great to see how it goes after the rebuild.
 
:), good going, the internals are a hell of a lot simpler than i had imagined, the rx7 always seem to be made out to be a bit troublesome, but that looks quite manageable, good on you dude and best of luck :)
 
Get the ceramic seals, you know you want to :D And dude you have steel in your underpants! :eek: :D Can i ask why you're doing it yourself though? If you can afford such a luxary as an 300+ BHP car, surely you have enough cash to get someone to fix it for you? Or is it that steel in your underpants making you do it ;) :D
 
Not everyone with a powerful performance car is loaded mate. I personally spend most of my money on mine, and I therefore dont have loads spare to get garages to do all the work when something goes wrong.

I should imagine DreXel has a similar situation because getting a garage to rebuild an engine is always expensive.

Yep, that's about the size of it. A rebuild would cost £2.5k+, then add the cost of getting it ported.....

Doing it myself, the total cost including the porting will be less than £1k.

As for ceramic seals, they are around 6 times more expensive.
