I think rotary aviation has a video about removing the engine also so that might help out. I am gonna buy the rebuild video and see if I'm up to the task - I really like doing **** myself 
. I know it's a lot easier to rebuild a rotary then a piston engine though, but you should be able to do it if you have some mechanical skills 
. Good luck man! BTW definetly streetport that sucker!

I bought both Bruce Turrentine videos of the engine removal and rebuild from Rotary Aviation. Both are good videos.
Its not hard to remove it provided you have the right tools. I just pulled my engine like a month and a half ago. Didn't have any problems at all and I'm getting ready to pull another engine out of my other car in a few weeks. The ONLY hard part would be putting everything back together. So make sure you take a bunch of pictures and label/tag/bag everything up.

Fairly easy to rebuild an engine, the hardest part by far was pulling it out and getting it back in. Scathcart has a write up somewhere around here on pulling the engine. It should help a lot if you have never done it before.

a lift of some kind to pull the engine, sockets, screwdrivers,etc. also assorted wire brushes and some good solvent for cleaning. a torque wrench is a must for reassembly. also you will have to take the engine somewhere and get them to remove the flywheel lock nut unless you have a 3/4" socket set. vaious prybars are needed to separate the engine halves, and Be Careful. if you plan to reuse any internals (side, corner seals,etc) you will need a micrometer and feeler guage to measure clearances. also to replace bearings you will have to find a machine shop with a press and a lot of attatchments for it...most small ones dont have the right size thing to push the bearings out. if you want to port it (which you should) you'll need a die grinder or dremel tool (you can get a dremel at wal mart for like $20, and then another 10 or so for all the little bits and stuff you'll need)
basically...youre looking at about 20-50 worth of work youll have to contract out (flywheel, bearings) due to not having the tools, and the rest you should be able to do provided you have basic mechanics tools.

cheery picker, engine stand, rotary adapter, pound per foot ratchet and inches per foot ratchet, lube oils, grease, carb cleaner, engine degreaser, simple green soap, more car cleaner, gasket sealer, red and blue bolt pastes, etc.. etc... tooth brushes, part cleaners,,, your extensions, the normal mechanic stuff jacks, jack stand.
P.S. Youll gain knowledge sure... But if you need teh car running I rather pay 1300 than do it myself than pay 1000. ( I rebuilded my engine myself about 6 months ago)

you will need
Metric combo wrenchs
metric sockets (1/4 3/8 and 1/2 drive)
torque wrench
Plier set
skrew driver set
Jack stands
Feeler guage (recomended)
micrometer caliper (recomended)
lables
gasket scraper
Enough space to lay everything out so it doesn't get lost
You can rent a hoist
it is better with an engine stand, but you will have to buy and adapter since our motors don't fit most stands
Workshop manual (absolute nessesity)
enough time so you aren't rushed and botch it
a freind with some mechanical experience
There are a few other things you might need I have fogotten about, but this is a great thing.
I remember my first rebuild. I was so proud of myself, Then i started it up for the first time and it was so smooth and beautiful sounding. I was hooked. I recomend it to anyone that is good with their hands.
If you don't have some of these tools, ask you freinds if they want to help you and if you can borrow their tools. If you ask enough people, you could have a whole shop ful of tools at you disposal. Keep track of who belogs to what and make sure that when you return them, that they are in better shape than when you got them. That way they will be willing to let you use them again.
good luck

i have another car i can use until i get this one running. And where are you getting yours rebuilt for 1300?? The shops around here (DFW) seem to charge upwards of 2000...

Minclo if you are asking how to pull a motor out of the car you might not want to try and rebuild your own rotary engine. Not flaming you just a suggestion. You would be better off pulling the motor yourself and sending it to Kevin at Rotary Reserrection and having him rebuild it. Also he can inspect the parts so you are not rebuilding a motor with a warped housing and not even knowing it. thats my 2 cents

Rebuilding price depends on how damaged the parts are or which parts are within spec. If the apex seal went out pretty bad, then expect to pay $400 EACH for a brand new rotor housing. Of course, you can probably buy used rotor housings that are within spec that could be just as fine. Ultimately, I'd say $2000 is a safe bet to get it done RIGHT.
No rebuild is cheap if you want it done correctly the first time. Some people take shortcuts but that is their car. You may want to replace a few gaskets, get the injectors professional cleaned, or maybe a rotor was scored or scratched, etc.I personally saved up $2000 just for rebuild + tools and I haven't even opened up my engine yet.
I think the experience will be worth it though. Nothing like saying you've rebuilt your own engine.

So true, and once you put the money into the tools and get some experience you will be able to rebuild your own engine fairly inexpensivly later on. I really wish that I learned that right off the bat, however I sent my engine out twice (both blew up under 100 miles) before I said screw it and rebuilt it myself. It is a very good experience, and will teach you ALOT. Just make sure you take alot of time cleaning and specing everything out.
