Engines will usually need a build around 100km, basically just wait and see. Dont presume it will need a rebuild, just see how it goes.
And yes I think you could rebuild the engine, if you wanted to learn etc. However I would not if I was you , becuase the amount of tools you will have to buy to check ALL of the tolerances would out way your savings. Saying that some people rebuild without even checking any clearences.

Hi SubZero,

I\'m of the opinion that unless you are really good at this sort of thing, give it to someone who has done it before.

BUT - saying that, means of course you don\'t learn anything.  So if you are confident then why not.

At 100,000kms you may find that quite a few parts in the engine will need replacing, if you don\'t then there is every chance that it won\'t last another 100,000kms.

If you are modifying a car (i.e. increasing performance) with engine that is old, then there is no telling how long it will last, and if you are investing in getting it to go harder etc. then the old engine will always be the weak point.

If you do rebuild it yourself - please, pretty please provide us with some piccys etc.

Guys on here like Ross (DRAGON), Carl, Pip Gardner, Prototype (Philip) and a few others have built/rebuilt engines so they should be able to provide a bit of info for you.

Hi There

I reckon you could do a rebuild yourself. Hell, if you can figure out one of those funny up and down engines, I think you\'ll find a Rotary is actually much simpler!!

I have done it a few times myself, and I am no boffin. The good things are, there is no:
Timing, springs, levers, or belts.

I agree with the above posts. There are lots of little things to measure, and some grinding to be done with new seals. There are places where "Finesse" (look it up) is critical.

You can, though, buy a video to help you by Bruce Tarrentine.
