Rebuilding my buddy's engine

I rebuit one of my friends engine the other day and he went crazy taking pictures of what was being done. It was pretty cool because I was teaching how to do it and letting them do it and learn as we went. The engine was street ported all new seals, springs, gaskets and bearings. Didn't know where else to post this. We named this engine "the hornet" and you can see why in the pictures!!!! Enjoy

I'm the guy with no shirt and tattoo's in case youre wondering

Looks like a fun time.

shock'm Bra.

I'll probably be doing that at some point in the near future (as well as redoing my entire engine bay if money is right).

wish i had the skills to do all that. im gonna learn to do engine work on a jeep motor i have. then maybe ill think about doing getting my hands dirty on a rotary

Looks good.

Was it warm enough in NC to be shirtless? It's been friggin 20 degrees here in VA! Good job nonetheless...

It was actually pretty warm here until these last days somewhere in the 70's. Plus we were inside of my garage so it wasnt bad at all

and thanks for all your compliments guys.

Nice. I need to learn how to do that.

Hey polito, it only took you two days to rebuild and install? Damn, was this like, two days hours wise, or actually two days? I would think that a rebuild would take a solid week or so what with all the cleaning, assembly, reasembly, tolerancing, replacing random broken stuff, waiting for parts, etc...

That's damn fast, good job!

That looks interesting. My engine build will start sometime around the beginning of next year. The yellow color is interesting, why not black like the rest of the car?

/\ Yeah, but you dont really know what you need until you remove and tear down the engine, clean stuff, and spec it... then you gotta order parts, buy tools you might not have, etc...

Maybe if you just order a seal and gasket kit, and reuse all the hard parts on the engine just the way they are it could work, but then how good of quality would a rebuild like that be?

Honestly it depends. For the most part if you make a habit out of building and rebuilding engines you're going to have parts, or at the very least the most likely candidates for replacement before hand. Spare rotors, spare irons, spare housings, spare bearings, spare springs, etc. If you know the rough condition of the apex seals and side seals more than likely you can reuse them.

If however you're a low volume builder then breaking the engine down and specing is what will take time to do. When I first built the engine it took me a week to clean and spec the parts, even then when I was getting ready to re-assemble I happened to miss the conditions of the bearings in stationary gears so I made it a habit to spec every part at least 3 times. once just after cleaning, second when I'm laying out parts for rebuild such as the rotor, 3rd just prior to installation. Granted that's redundant as hell, but it forces me to pay attention to what I'm installing... never mind that when I took my engine apart the next day to ensure I didn't miss a coolant seal I was able to put it all back together in an hour or less because all the parts were spec'd from the previous build.
