Mmk... I bought a 91' RX7 non-turbo and it has a blown apex seal. Would it be better to rebuild the engine that is in the car or jus buy rebuilt one? If it is cheaper to rebuild the one that is in it... where can I get it done in Indiana or around Indiana for the smallest amount of money?

 

dunno if this will help, but I called arounbd a few places asking for the same thing, basically 9-11 hours work + parts, so this might help you out.

Thats a engine pull out, rebuild, put back. (+cost of parts)

keep in mind you can get these engines for just under 1,000$ if you look around.

 

umm i would say if u have the skill too do it yourself rbuilding will be cheaper and u could street port the engine while u had it apart (not very dificult if u have a dremel or one of those special bits that is coated in that gold colored stuff cant remember whats it called some say the drill bit is better because it slices the metal clean keeping it cooler have the part number somwhere round here if anybody is interested (its from home depo) but if u dont have the know how or have enough freinds with the knowhow buy a good new engine and do a compression check on it if u can too make sure u dont have this prob again. there are rebuild kits for sale from atkins rotary going for 295$-825$ http://www.atkinsrotary.com/store/cu...me.php?cat=591

 

It's always cheaper doing it yourself, and you then have total control over the quality of the finished product...

 

right wayne, which is a good thing for guys like you and I but . . .




I have fixed three motors for indivduals who did it their own and screwed up just in past several months -

 

screw up how??? its not that difficult to rebuild.... doesnt take a scientist.... the only thing that takes some skill if anything, is deciding wat parts to replace and what you can keep....

 

some people have no mechanical experiance (they prob shouldnt touch a 7 then) the dificult part isnt the engine itself but all the little stuff around it (electronics hoses etc.) and some people dont have the guts too try it and some would never have the determination too follow up with all there mess ups and find all the bugs (first time bound too miss somtin ohh use a vid camera on a stand and talk into it as u take stuff out and point it around the baay helps alot later if u cant remember somtin and use a bunch of zip lock bags for ur first time and label where and a what all the seperate parts / bolts are)

 

Ziplock bags are necessary for anyone rebuilding an engine... especially messy people... unless you have spares of every nut and bolt...

 

Mr Gadget, how'd they screw up? I'd like to know- you know what they say- it's better to learn from other people's mistakes than your own

Even the best auto mechanics on earth learn new things every now & then...

 

hey guys thanks alot for that site but the only place around where i live (muncie indiana) wants $4500 to rebuild the engine. I dont have much mechanical skill so i dont think i should do the rebuilding myself. where is a good place to get it done? i will drive if i have to to get it done cheap. and... if i do decide to get a rebuilt engine... where should i get it from because i found them on mazdarx7engines.com for $2000 plus a core deposit. so how do i get them for cheap?

 

First things first...Get that "cheap" thought out of your mind. If you want it done right, then "cheap" won't work.

If you are not mechanically inclined, then don't bother trying to rebuild it yourself. It is very easy to build a great looking engine that will run for 1000KM then seize. It's not entirely difficult to put together one of these engines, but there are a number of "gotcha's" and details that can come back and bite you. For example, CLEANING. Everything must be spotless. Also, the front cover o-ring issue, torrington bearings, etc. There are also a few tools you will need that most don't have...

If you have your heart set on cheap, then look for a good used engine.
