RX8 Rebuild
 

I am rebuilding engine in my RX8 but I am not on which kit I need to buy for the minimum this is the list of all the kit http://www.atkinsrotary.com/store/home.php?cat=629 they also have a rotor rebuild kit http://www.atkinsrotary.com/store/se...=search&page=1

You can't tell exactly what you need until you actually crack open the motor.

But for starters you will need all the soft seals and I would replace all the hard seals on the rotors too.

Rotor housings need
-Water Jacket 4 inner and 4 outter

rotors have 3 apex seals per rotor for a total of 6 for both rotors
12 side seals
8 oil control rings
12 Corner seals. Some say they are reusable some people don't recommend it.

you will also have to replace all the springs for all the seals. I'm not sure if rx8s use two springs per apex seal but all the motors I rebuilt for my rx7 I used one long and one short spring

you need a new oil pan gasket + probably two tubes of RTV black for certain areas where the houses touch or else the motor will leak.

Front plate gasket and O rings
Dowel Pin O rings
Water Pump Gasket
Tension bolt O rings (also known as gaskets. They look like washers with a little bit of rubber on them)
Front and Rear main seal
Oil strain gasket

that's all I can think of at the moment since I'm half asleep.

Mazdatrix has everything you would need.

Good luck

Your doing it yourself? Haha. If you have to ask then you are in trouble. PM Tecnik or whatever his name is, he is a factory tech. Or PM sleepy-Z

if you have to ask. dont do it.

you gonna mess it up.

Rotary engines are extremely simple and if you wanted to build it alone your first time just pick up the atkins rebuild DVD. It has everything step by step and all the specs you would need to know. I rebuilt my first one myself a years ago back when I was only 17 and had no mechanical experience except for changing oil. It is very do able.

i have a lot of help for the rebuild

make sure to have a feeler gauge too, and the other proper tools.

If you have experienced hands to guide you through it then go for it. Honestly I know guys who can rebuild a motor in a day. That includes pulling and dropping back in.

The hardest part is the cleaning of the rotors. Brass wire brush or pressure washer should do well. Wire wheels work great too for the faces while the brushes can reach inside the seal/spring grooves. Good luck

Right Sir! the seals are pretty easy to install but the oil rings and some other parts can easily make the difference between a successful rebuild and a short lasting one imho

Would you mind to specify?
I'm by no means a professional rebuilder and you know that,anyway with a good help and a "master" that supports you the first times then i think that anybody could rebuild an engine. Granted the subject takes his time and finds the right supporter ;)

Are there more pitfalls to rebuilding a rotary than rebuilding a piston engine?

Funny how you guys make it sound so easy. yes rebuilding it may physically be easy but one little screw up in the wrong spot and you will be doing it all over. I have 6 or 7 Honda motors a L 280 motor, and the LT1 in my Z28 and its all about the tools and the details. If you have any extra motor then fine but if its your DD then that's a whole other story.

well i think ppl are missing point of this thread anyways...i wast asking how to build i was just asking what parts will i need and possible other things i may need

^^ and I think you still dont get the point.

if you have to ask, dont do it.

what is the point of any of us telling you what do you need? every engine is different. Just because Peter need only Apex for his engine doesnt mean David's engine needs them.

I can tell you to get all the seals/o-rings, I can even give you all the part #. I have it all in my list. but do we know if your housing is bad? nope. do we know if your rotor is bad? nope. etc.

so, just forget it.

and if u read i said i am not doing it myself...eventually i have to learn this...everyone starts from scratch no one knows how to rebuild engine from birth

except baby jesus.

VS8, why can't you ask these things to the guy that's helping you? :)

im just trying to get some info for myself

Sometimes there are things that you should let others to do it for you.

but I mean if you have the heart and deep pockets. go ahead.

A guy is selling a DVD detailing a rotary rebuild. From the clips it seems very detailed.

If you go through with this, could you do everyone a favor and post pictures of the teardown?

How many miles are on the engine you plan to rebuild?

If your car was still under warranty you would get a reman engine installed for free... Didn't you already have to buy a transmission out of pocket???...:sad:

Why not buy a low mileage engine??? there are lots of them on eBay???:crazy:

Sounds like it is time to take off all your mods, sell your car, get another Manual GT with low miles and a clear title. These can be had for around $12-14k. Then you would have a factory warranty.

let me add this up for you.

new motor rebuild would cost let's say $1500-$2000, save this money sell you car for around $8k add the $$$ you did not spend rebuilding the engine on a salvage vehicle to buy another one...

here is one that has been on Autotrader, 04, 47k miles, engine replaced under warranty 2k miles ago.. for $10,500

let this be a lesson...

salvage tile =no warranty=:sad:

Predicted answer "I am rebuilding it myself so I can go turbo later..."

i am doin upgrade not stock rebuild upgraded seals and stuff

i dont care about the warranty and plz stop mentioning it...i find it fun learning to do this stuff myself...yes a warranty would be nice but i also see this as learning experience i barely paid anything for tranny and had free labor because i learned to do it myself

You know what do whatever you want with your d@mn car hopefully you professionally upgraded rebuilt motor does not blow up in your face....:banghead:

did you even read what Charles Hill said about rebuilding these engines... Kids never learn...
