RX8 Rebuild 1 now 2 :-)

Recommended Posts

Hey lads, bought a non running RX8 to do up and sell, after new plugs and leads, had trouble starting the car towed it and it started with a tow but knocking, after a look over the shell I decided against going any further as the sill were rotten, I found a shell nearby for handy money which was extremely clean, not even surface rust on the sills so I purchased this one, took engine out of the grey one last night so will start the rebuild on that tomorrow, haven't rebuilt a rotary before so looking forward to it ,ill keep ye posted with pics of engine build and shell refurb/transplant etc

True that @Rex Ruthor Best bang for your buck is to street port the plates while Ya have her open,  that along with the remap from @littlefeck.

Gutting the cat is an easy couple of horses that'll help her breath freely, and it's free if you have a metal bar lying around.

Also the ignition upgrade is a great addition for long term money saving and reliability.

Good luck with the venture anyway, keep us updated buddy :)

Ya there the DVDs I have quiet good. I'll check up on d porting , as for the cat it's already gone. Do the D585 coils make much of a difference.

Some rotary specialists have said the ignition upgrade can be one of the best upgrades one can do. I find it gives a solid, reliable and smooth spark through the whole power band. But the dwell times need to be adjusted by @littlefeck to suit the rx8, or it could be slightly lumpy or give other issues.

The porting needs to be quite precise depending on what you plan on doing. Unless you're fairly well clued in on the coolant and oil channels, then I'd say ordering templates are a must. 

I do the porting at shadow rotary in Dublin if ya decide ya want them done , just shout ;)

Good advice from Richie, no better man to give you advice on porting. He does them for shadow as said. My point is many know it all's have tried this in the past  with no luck so it would wise to take Richie's advice or even better get Richie to do the porting for ya B)

Went at the engine before work and at lunchtime. Removed sump and it was like Gold Rush on d discovery channel except I had brass not gold :(. Done more dismantling at lunchtime and removed oil pump and chain and all bits on that side, Very bad wear on the bearings on the stationary gear, Waiting on a socket to open the flywheel so didn't do anymore ripping today, will keep ye posted 

 

also I find it hard to upload my photos, any help thanks

Finished ripping engine today the rear plate and front plate aren't too bad all the wear/burning is on centre plate, my knocking noise was that the bearing in the rear rotor was spinning in the rotor itself, think this caused heating which burnt the eccentric shaft/bearing/rotor so parts list is as follows -

-full gasket/seal kit
-eccentric shaft
-all eccentric bearings
-rear rotor
-centre plate
- and I think 2 rotor housings

*if anyone wants to donate parts to my virgin rebuild that's fine too :-) *

You asked about mods while it's out: one thing that seems to be getting very common is the oil pressure increase mod for the 13B-MSP - search for an "RX8 thermal pellet" & "oil pressure regulator modification" relating to the regulator on the rear plate/rear iron; the "thermal pellet" replacement & comes in a lot of engine rebuild kits as standard now for the RX8. These up the oil pressure in the engine closer to that of the Series 2 RX8 engines. Worth doing a search on it for reliability. ;)
