Hi,
Im considering a new car in about 6 months...and Im looking for a RWD turbo.

Im considering the RX-7. If I got one, it would probably be the newest generation...93-95.

Ive heard that the rotoray motor is difficult to work on and a bitch to maintain...for obvious reasons. Ive heard shit about the apex seals, and how they need to be replaced often.

If I did get one, I would want it to be a RELIABLE, daily drivable car. I would probably not do anything crazy to the car...probably just the basics...aftermarket filter, straight pipe, catback, fuel system upgrades...most likely not get a boost controller though.

I know there are only a couple of RX-7 owners on the board, but I would greatly apprietiate any advice or input you have.

Thanks,
Mike.

 

FDs brake apex seals fast due to over boost..

My car has 107k original miles..and inside is stock...I have a friend just break a apex seal and he has 70k on it..

Theres no set time on rebuilds...Why is it so hard to maintain a rotary?
tell me what you heard?

Yesh they are harder to work oncause not many peopel know about rotary engines...

You dont want Jo Blow who works on his trailer park friends Fords to work on your rotary right?

If you want to talk 1v1...and I hate PMs..just aim me..my aim name is in my info..

 

yeah rx-7 is the way to go apex seals don't just blow apart in less u have high boost on them but they make apex seals for those applications but it would be a good move to by 3 gen there are nice cars i have an 85 12a street port just thrashed an apex seal but puttin it back together in my garage that how easy it is to work on for me but u don't want any body who doesn't know what there doin to work on them me and rotary 7 have people tht work on them and do a good job i work on my own rx and a friend of my at hf motorworks in st.pete if u have any question u can call us at 727-522-1874 happy rotoring !!1 :bounce

 

Cool...Ill IM you sometime...

What do you "RX-7ers" think about this RX-7 for sale?

It looks nice, and the guy says "Rebuilt engine with 650 miles on it, all new black silicon hoses"....should I be worried about that at all?

Thanks,
Mike.

 

Nice *looking car * High mileage..The rebuild dont mean shit..cause I personally would of got it ported and insteadd of 2mm apex seals 3mm..and other inside work done..

So that rebuild shit to me dont mean shit...14k for a car like that ..with 88k on it ..is high pricesd....run a car fax on it..see if the admins of this site has a hook up to run it for you...

If you did get a FD Go single turbo set up ..with a boost control..The mods are good to do on this car..and you can be on the easy road on beating Vipers..and Corvettes all day..

Yeah out of a 1.3L engine..

 

the 3 mm seal thing is sooo debated, its not necessarly better to have 3mm seals over 2 mm, there is no proof that they are any better

And how can you say that rebuild doesnt mean shit? So he didnt get a street port, wow you can still get tons of power out of a non street port motor if you really want to, street port aint god, sorry

And the answer the question on the vacuum lines all being replaced, thats good cause thats like a 400-500 job, and the old hoses crack after a while

And single turbo thing? come on not everyone has 10k to get a single turbo, a stand alone ecu, all the fuel stuff that needs to come along, radiator, bigger intercooler, man you are talking about a big thing not like a 100 dollar mod

I myself was looking at that car too, unlike what that dude says look on autotrader or ebay, thats a pretty damn good deal for that car! I myself am not getting it because I am currently looking at a single turbo rx7 with a street port (hey if it comes with it its all good )....but anways dude higly look into that car it seems like a good deal and street ports and single turbos are not a must, there are guys that hit 11s on stock turbos

 

Yeah, get a rotary man! They are too much fun. Once you get a rotary, you won't go back lol. I have one that has 185,000 miles on the orginal engine and it's a turbo! It runs great.

 

Going by number stats ..your right.Im not sure if 3mm is any better...BUT the cost of stock apex to after market ones,Your better off going with aftermarket...

Ok now about the stock rebuild..I personally wont go back to stock specs...Most people who mods thier rotarys and need to go with a rebuild wont stay stock ..they would port..and that dont mean just street port..

J port.....Monster port...large street...small bridge...etc....etc.


Ok now talking about the single turbo set up on a FD...first of all ..the car it self is not cheap..and who said $100. mods? If you want that buy a Honda and go to PepBoys and have a field day..A rotary can be expensive if you dont know how to work on them or dont have any one to help you...
Theres always people coming across rotary forums with FDs forsale in the 15-18k price range...(Normal for a stock clean FD) with shit loads of Mods.. ported..ECU..injectors..kits.. rims...Single turbos..etc etc

and yes this car can run 11s with stock ports...and stock turbos..but think about ecu upgrades..and injectors..

Not just a bone stock FD....

 

well obviously you need injectors, a ecu (haltech, pfc, etc) and a fuel pump (can get a supra fuel pump for about 100 bucks) and then comes bolt ons, like exhaust, downpipe, midpipe, intake, etc. but 11s can be done on stock turbos and stock port, i doubt the turbos will last too long but it can be done....but thats not the point, the point is it can be done on a non street port motor...of course if the car has a street port or u need to rebuild the motor get the street port but if the motor is healthy dont take it apart for a street port.

And unless the car is going to be your weekend racer your car will be almost undrivable with a huge port on the engine, the idle will be just too wild and you will probably stall too much, that is why street port is all i personally recommend

And the thing with apex seals, there is still no proof that aftermarket seals are any better then just factory ones, both will crack if you lean out the car, I have heard actually that 2mm seals have less friction and can last longer then 3mm seals that have more friction but thats also jsut opinions I heard

 

Well I hope you know some engines came with a 3 mm apex...
and some came with a 2 mm apex..

12a/13b


Factory apex are hard and will damage housings and rotors if they brake..
You can get aftermarket Apex seals that are made otu of carbon and aluminum.and when they break the just dicintergrate<spelled wrong<<and you have less of a chance of damaging the hosing or rotor...

My car came stock with 3mm seals..im staying with 3mm seals..BUT Only reason why I might stay ith stock seals is cause they maybe stronger under pressure (boost)

Im still checking on alot of diffrent things for the car...and thinking about changing my set up..
