If you were closer I would help you get the motor running for less than $600. People on this forum is very discourage of rotary because they paid someone else to work on them instead of doing it themselves. GL if you ever decide to buy it let me know?

I am sure you are probably a good mechanical incline person and we are not trying to discourage you, I think we are just trying to let you know from experience that your budget is too little for a car that most guys spend an average of 2 to 3 grand or a rebuild doing it them selves.
rebuild kit -$1200
bearings-$200
used rotor-$200
used rotor housing-$200
and everything else that will brake and need replace along the way.

Ive gotten my motor rebuilt on a budget. It was only 3200 dollars lol. But in the process I had to buy a boost controller, hks twin power, fuel pump fuel regulator. So the rebuild cost about 5k. Not to mention the 10k+ i put in to the radiator, ast, power fc, gauges, fuel rail, injectors, upgraded turbos when my stocks were cracked at 50k miles. So yes it is a great fun car but i hope you dont plan on retiring early.

QUESTION: what if the only problrm with the motor was a seized rotor... could i just replace the rotor and rotor housing??? the previous owner says there is only 2,000 miles on the engine.

are you planning to do everything yourself? If you are, then by all means do it. but with 1200 bucks, you're not gonna get that thing running for a long time
even if you find a JDM (8bit wiring) motor for 1200 bucks.... keep in mind, you pay for what you get. most shops will still charge at least 750 just for labor to drop that sucker in. not to mention you need gaskets and some other small parts, new plugs, new fuel filter. then after you drop it in... what if it doesn't fire up after trying 50 different things.... pull it out and the engine is shot, then you're screwed
minimum rebuild fee when you drop a blown motor car off is around 3500+-. that's if you're lucky the apex seal didn't scratch ur rotor or housing before it was spit out of the exhaust, which happens a lot of times... if they need to be replaced, they are around 650 a piece new
HONESTLY..... these guys all have FDs, they're not jealous of you... this car sounds shady
good things comes to those that wait

by all means do it then, you are going to learn waaayyy more then you ever expected while browsing this forum and doing it yourself.
Remember, search before you ask... You may get 50 different opinions when you ask something but this is all coming from people who have more then likely done what your about to do so Id take it as advice, not an insult

@James...no one is trying to turn him away from owning an FD but they are trying to help him be realistic. How many times have you seen someone say, "I'm a proud new FD owner" and then a month later say, "This car sucks" because they don't understand the time and effort that goes into having an FD perform well and then maintaining that level.
I believe most of the posters in this thread realize that despite the OPs enthusiasm and willingness to do work himself that he is most likely in for a LOT more than he is expecting. I still don't see this situation turning out well but I hope for the best. The car may be a "deal" but I'd bet there is more wrong with it than the engine. =)
Just my 2cents.

well, the the owner does not even know if its a seized rotor thst was just his guess... or at least thats what he told me. is there any signs of telling if its a seized rotor with out pulling the motor... like, will the engine not turn over or something like that?

Seized rotor is when the engine won't even turn over because there is a piece of carbon stuck somewhere. Seized apex seal is when the seal is stuck and won't come out to make compression. Seized apex seals is often an excuse sellers use for a blown motor.

I'm a rotary newb compared to a lot of guys on here because I'm only on my 3rd rebuild (because of a bad wiring job on the boost controller from previous owner) but, yep. ..
Seized motor would mean it won't crank and would probably have to be something bad like, jeez, maybe really bad bearings that disintegrated and caused major component contact, or sat with water in it and rusted fast over a long period of time, or maybe major breakage of one of the end plates that caused an off center e-shaft and major contact. I don't know about this fabled 'carbon jam' I've never seen one, but if there is such a thing, why not try putting the car in 5th and then pull it backwards with a tow rope a couple of inches to run it backwards?
Otherwise, if he's claiming stuck seal, and the engine turns over on the starter, take a compression tester with you and look for 3 even bumps per housing (disable any check valve on the tester). If you don't see 3 even bumps on both the front and rear housings, make sure you negotiate as if the engine is blown.

While it's good to advise new/potential owners about some of the pitfalls that can be encountered with these cars, some of you guys go way over the top with it. I agree with JamesPond, these cars can be fixed up on a budget if someone takes the time to diagnose the actual problem and come up with a plan of attack. A lot of people just seem to throw money at the problems they have and then get discouraged because they are spending so much without the desired results. It may take a little longer to get everything you want/need on a budget, but it can be done and it's worth it in the long run. Took me a year to get my FD back on the road, but after daily driving and racing it I would do it all over again if I had to.
Now I wouldn't recommend over extending yourself with this car. If that budget is purely extra car fund $$$, that's one thing, but if you're dipping into grocery money to support a project car it's just not worth it.
