rotary guys chime in please... just got an 89 rx-7 with blown apex seals
 

ok so i just picked up this rx-7 with blown apex seals.
i've never worked on a rotary, but i'm not afraid to start now.
the plan is to have it turbo. the question is should i buy a jdm turbo 13b motor for 800-1000 from an importer or should i rebuild the 13b i have and turbo it.
side questions are

are the non turbo and turbo motors the same?

how much hp/boost can a nonturbo motor handle with a fresh rebuild? (i know i hate these questions also, but don't flame me too bad.

if it would be better to rebuild the one i have i'd rather do it cause i don't want the stock turbo anyway.

Search N/A Turbo build on Rx7club.com

But honestly I'd say it's worth it to get a full rebuild kit and just do it yourself, if the broken bits didn't score the irons you'll be alright.

That motor can be out and apart in ~1hr30min if you have a long enough pipe to get the front cover off. Impact gun won't work more than likely, use the pipe.

You never can know the exact condition of a JDM unit.

cool, i'm gonna be doing a lot of reading on these motors for the next 2 weeks till i get paid again. i'm gonna pull the motor sometime this week and break it down to see how everything looks.
the problem is it's been sitting for 10 years so i'm not sure how this motor is gonna look inside. i might end up looking for a blown motor and rebuild that one. i've seen what motors look like after a few years of sitting in yards so i can just imagine what this one is gonna look like.
i picked it up for $200 and a $165 tow
$365 for a car i've been wanting for the last 8-10 years. i'm pretty happy
only a little bondo on passenger side fender and a tiny bit of rust on the sunroof, but not inside the sunroof track.

Not bad, looks in good shape. So where are the money shots?

---- I'm jealous.

Pretty sweet you got a GXL too, four pot brakes and such.

It's an S4 is it? Rotors are a lower compression than later N/A rotors but you're better off getting TII rotors or something of the like anyway, as the N/A rotors were all LPC.

you stepped into the world of trouble man, i still need to get another "good" motor for my 83 gsl. sucks i miss driving it so bad.

Re: rotary guys chime in please... just got an 89 rx-7 with blow apex seals
 

Shut the ---- up, 13b 3-4mm seals > 12a 2 piece iron seals.

All 12a's should be rebuilt when you get them any way.

i'm gonna take the motor out and drop it in my wifes 91 civic 4dr then put her d15b2 in the crx to sell. i'll get less money for it, but then our 4g4d will be fast.

i'm glad i found this rx7 today, i'm so excited.
i've been looking on craigslist every day for
fc rx7
mk3 supra
3g camaro
1g eclipse
65-67 chevelle
65-70 nova
i search for cars under 1k and i've been looking for about a month. i've seen a few things, but something about this ad made me drive 50 minuets to look at the car. when i saw the interior and the body condition i couldn't pass it up.
the tow truck driver offered me $500 right when he saw it. we were talking and i told him i paid 200 for it and he said "i'll give you 500 right now". i didn't even think about it.
