since i haven't seen a basic rebuild parts list and seems when people have needed one they have found different results i will compiled a basic rebuild parts list containing most of the cheaper, simpler to get and reliable sets.
here is a few sites for rebuild kits and internal engine parts that have reasonable prices:
this is a basic fairly cheap rebuild kit option, one that i recommend:
1) rebuild and installation gasket set from mazdatrix.com
86-88 Non-turbo 10-2710-8DF1 $181.85
Turbo 10-2710-8DF4 $317.28
89-92 Non-turbo 10-2710-8DF5 $186.27
Turbo 10-2710-8DF6 $351.03
2) front and rear main seals from mazdatrix.com
front main seal 10-6050-0820 $4.33
rear main seal 10-556A-1668 $9.32
3) FD corner seal springs, you will need 12 of these, price from mazdatrix.com
FD corner seal spring 11-C240-NF01 $2.67 each
4) inner and outer oil seal o-rings from mazdatrix.com, you will need 4 of each
Small diameter for inners 11-3410-0820 $9.60 each
Large diameter for outers 11-3430-1202 $18.50 each
5) apex seals and springs from rotaryaviation.com
RA apex seal and springs $182/set
Hylomar HPF, available at your local parts store as well as some high temp RTV Ultra Black. you will need the hylomar to seat the comp. o-rings to the iron housings and all misc. o-rings during the rebuild. the RTV is used to seal the comp. o-rings to the aluminum rotor housings and your oil pan. you will also need some aviation compression sealant to seal the legs of the rotor housings to the irons.
basic price for a complete rebuild including installation gaskets for an 86-88 n/a is $521.54 plus tax and shipping not including sealants or fluids or other items listed below.
on top of this i recommend replacing your upper and lower radiator hoses, both heater hoses, especially the driver's side one and coolant lines to and from the BAC. replace all drive belts, fuel filter, vacuum lines, PCV hoses, spark plugs and determining their condition, your motor and tranny mounts. you will also need to pick up a new oil filter and thermostat, you can get these from mazdatrix as well.
for those T2 builders on a budget you can retrofit 13B n/a housings to work in your rebuild, use the same series engine housings and swap your exhaust port sleeves over to the n/a housings and take them to a machine shop, have 'one' housings coolant passage milled straight through to the coolant jacket and have them cut a recess to fit the o-ring to seal it to the LIM and use this rotor housing for the rear in your rebuild. Kevin Landers has a good writeup on this but i don't have it marked so if someone has a link it would be appreciated.
you can pick up videos from all 3 links i provided at the top of the page, IMO all of them should give you the basic knowledge to take on the project yourself.
anything i missed i'm sure the rotary police will bash me to death on, so will the biased kit builders.
