Rotary engine, could an idiot work on it?
Discussion
I recently was told my Rx8 needed a new coil pack, HT leads & sparks and was quoted £480 by my local mazda dealer to fix this. Anyone have any idea how easy it is to do this kind of work on a rotary engine if you have little knowledge about engine upkeep? online walkthroughs etc. and where would be best to get parts online? thanks!
klearn by doing!
ht leads, coil pack and spark plugs should be fairly easy. Just depends whats in the way- being a rotary engine, things might be located in the bowels of the engine bay, or you might have to undo other things to get access. I havent personally worked on an Rx8 though, should could just as easily be a piece of cake!
A fair bit of snooping on an RX8 forum should answer all
Make sure you do things properly though- like tightening the spark plug up to the correct torque. Last thing you want is it working it's way loose and chewing the spark hole threads on the way out...

If it's anything like an rx7 the plugs should be easy as long as you have two elbows per arm.;)
Seriously though plugs were easily do-able with a bit of practise. No idea about the coil pack.
Socket wrench with an adjustable head will help a lot.
out of interest are the top plugs different to the lowers?

The spark plugs can be tricky to get to. Two of them are really only accessible through the nearside wheel arch. The coils are quite straight forward- behind the air intake. If you have the right socket set (with extension) then you shouldn't have much difficulty. But... DO NOT drop the bolts!
Leads are easy, but remember to connect them in the correct order.
Finally, you will need trailing and leading spark plugs (and fit them in the correct places). You can get the full set of 4 from mazdarotaryparts.com for about £100.

This might help, I've been consdering an RX-8 for a while and stumbled upon it in my research, http://foxed.ca/rx7manual/2003mazdarx8/
It only seems to work in IE.

They're offering a discount on leads when bought with a set of coils too.Edited by mizx on Tuesday 11th January 23:43
A friend and I done all this in about 3 hours on a rainy afternoon, lot of swearing and a few grazed knuckles but it was all pretty straight forward. We didnt realy use a manual or a guide however.
Sorted the running out though and was well worth doing.
Its actually a very simple engine.

Yep, I've done those jobs on mine having never done more than an oil change. The front passenger wheel will have to come off to get access to the plugs (make sure you buy the right type, they are expensive but important that you use the right ones). The coil packs are easy enough if you move the airbox (videos how to on youtube). The main thing is to make sure you connect the leads in the right way, there are how-to articles on www.mazdarotaryclub.co.uk.
Do you have all the parts already or do you want links to where I bought mine from (a lot cheaper than a Mazda dealer for the same things).
Edit, www.mazdarotaryparts.com as already mentioned are good and quick, I bought the cables and plugs from there
http://www.arlingtonmazda.com I bought the coils from here as they were quite a bit cheaper at the time but delivery was about 4 weeks

You don't even need to take the airbox of to swap the coils either, although most guides suggest this (time consuming) approach.
