12a Rebuild

[Dominic]

On a positive note, you now have 2 rotor housings and a set of end plates to practice cutting a big bridge port and enlarging the exhaust ports. Out with the dremel drill then :cheers You could then make a coffee table from the housings :Giggle  

Sorry to hear the engine\'s no good though.... arse!

Thats a dam shame sorry to hear that

the rotors are junk too (the groove is too big for the tips). I could rebuild the engine with new parts but it isn\'t really finacially viable.

Not sure If I read that correctly but could you get away with using 3mm Apex seals and having the rotor machined?

[shaunwil]

Thats not even an option, the 12a has 3mm seals as standard

Shame nobody makes 3.5 or 4mm tips for the 12a !

I think the only option some time next year is to get a 13b (or a renesis on the cheap) and run it on a carb !!!!

Not to worry, still have quite a few bits that are spare so its not all bad !

Wow - you learn something new every day - cheers for that

[shaunwil]

me too..........................

I think I\'m better off with a 13b with maybe a longer diff for fuel economy !

ive got 2 fd rotors with worn apex grooves that can be machined out to 3mm, dont know if they weigh the same as 12a rotors, also they maybe different compresion,
cheaper than buying knew if it can be done

[mullins]

a 12A with 13B rotors, nice! :Giggle

[travellinbob]

FD ones are a wee bit wider than the fb ones. About 10mm a piece IIRC?
  Why not try to get it back together, all the seals etc and not try to get it running on a stand? You ahve a spare box etc? Just need a battery, some coils?   It will help you to understand end float etc.

I\'ll probably rebuild it without any seals and have some practice with it. Thanks for the offer of the 13b rotors but there is just too much wrong with this engine even if the rotors where ok.

Anybody know anywhere a good egi engine is going cheap

Plus just how much do the renisis engines go for at salvage yards ?? Would be cool to run one of them on a carb !

I did see a renesis engine on e-bay a few weeks ago for £1500! but it was in shetland, or orkney, memory a bit frazzeled after too much christmas cheer!!

Was considering a renesis transplant a while back when I had some expendable income  Not as easy or as cheap a transplant as you\'d imagine from what I\'ve heard but fitting a carb would get around a lot of the fuelling technicalities. If you\'ve got the time and the money though then go for it, would be awesome. Think Ray has a Renesis block for sale for not much.

[shaunwil]

sounds like an interesting project !

Will pm ray and ask about it !

Would indeed be a good project, go for it Shaun :cool :Thumbsup!

From memory, think the block had a small water leak but nothing else major and LOW miles.

[shaunwil]

Had a chat to ray and there may (i say may) be a possibility that will become the project for the 1st gen

Defo worth a chat with Pip, Tim, and maybe some of the rx8 crew to do some sums and weigh up the issues. Apparently there\'s a thread on a renesis 1st gen conversion on another forum but I\'ve never found it.

Hope you decide to go for it! Cool to do something really different....
