i'm very new to rotary engines. :/

so i found a second gen rx7 for sale. and i'm interested in buying it, positives it's turbocharged.
and has a clean title.
and the car it's self is practically a steal.
negatives:
doesn't run right now. (i don't know for sure though because he didn't have a battery, also swapped the battery with his rx because he was in need for one as well)
and said it needed a rebuild (high miles)
the guy who bought it, bought it only for the leather interior because he wanted to swap it into his personal rx7. i've personally looked at it it's in great shape inside and out, but like i said it needs a rebuild.
how much does a rebuild for a rotary engine generally cost?

$1000+ for a rebuild, a lil less if you think you can do it yourself. Are you sure it needs a rebuild or is this one of those the owner dosnt know WTF is going on even if they do have another 7.

yeah i'd like to do it myself, but my shop teacher said we didn't have all the tools to do a rotary ourself.
i'm not sure about the owner he seemed to know, but you know how it can be when people are tryin to get stuff off their property.

You don't have all the tools?
Just pop for a rotary engine stand adaptor and a 2 1/8 socket and I think thats all might need extra...

First of all, get a battery and do a compression test. As long as you get three even pulses per rotor, it didn't pop a seal. If you get 0-0-30 PSI or something like that, don't get it since it will require expensive new parts, bringing the rebuild more into the 2k range.

Assuming that it doesn't have a blown seal, and you have the time to do it right, then go for it. It sounds like your shop teacher is willing to help, or at least let you use the facilities, which is a big plus.

As far as tools, the only real special tools are the rotary engine stand adapter (about 75-100 shipped from pineapple rotary or other places) and a 54mm (2 1/8") socket for the flywheel nut. Everything else is routine tools.

I recommend getting the rebuild video at www.rotaryaviation.com . It is excellent and gives you a good idea of what is involved.

you actually dont even need the socket...although you must be very careful about this ive R&Red the nut with an air hammer...with zero damage to anything...well except for the minor scratches left from the air hammer....and that was at least 4 months ago...i even just got a compression test last month and i still had close to factory compression...though i would get the stand..as it wont be that easy to to do it without it

Actually the rebuild kit with water seals, apex seals, and gaskets is about 1000+.
