rims...
clean interior


PROBLEMS
cold start blows white smoke...heats up doesnt blow anything (SLIM TO NOTHING)
idle is off goes up n down like it has a cam lol but idk ANYTING about rx7 motors
also needs a throughout berring or clutch cuz i put in gear and let clutch out goes nowhere

can anyone tell me what this can be? coolent seals? apex seals? how much can i get a 13bt motor for?

13b n/a is like 500 bucks maybe even less if you buy the parts separately and start playing legos.

the white smoke could be the motor flooding or the coolant seals are going out. maybe thats why it was 900 bucks but good come up

check if there are bubbles in the coolant filler neck. if there is time to rebuild but it might last you a couple thousand miles. as long as you dont drive with a white cloud following you then your good.

the humping idle could be a vac leak. try adjusting the idle by turning that **** on top of the tb until it reaches 750. then turn the pressure sensor, right next to the left shock mount if your facing the engine bay, to the highest then re adjust the **** on top of the tb.

have fun with your fc! remember to warm her up before playing with her

ehh every kid has to start somewhere. the ex owner of my fc drove the car until coolant spat out of the engine bay. drove it home while it was over heating. it miraculously survived the heat and is in ok condition now.

im not really sure the exact temperature but im guessing as long as it doesnt go above half then your good. the first thing i would invest in any fc is a after market radiator. these engines are like boiling cup of noodle soups fresh from the microwave. if you let the noodles get soggy it might never get firm? wtf.

i remember someone on my facebook had this car, maybe it was the kid you got it from or you ? i forget lol

for $900 though, that is a great looking car. bodykit and rims is easily half that. Just needs some wider wheels/lower offset, or some spacers for now since it has wide body.

If it is coolant seal, you will probably be loosing coolant from time to time, as well as seeing bubbles as suggested above.. There is videos on youtube that shows this.

There is a temporary fix trick you could probably try if that is the case.. You gotta flush the coolant really good, then use some engine seal/cooper block seal .. I forget the brand, but there is a recommended brand to use.. search the forum for block seal or something.. I read it helped some people get more life out of their until it actually failed completely.

It's an S5 - if the temp gauge goes over half at all it's over heating [someone on here the other day said that the S5 gauge has only 3 stages: warmup, normal, overheating]

If the coolant seals are really going bad you'll get higher temps [sorry only know the gauge] and water getting pushed out of the overflow.
If that's the case at least one of the 3 plates will have to be replaced when rebuilding and the others should be checked for coolant channel thickness [the inner seal's coolant channel side wall is the one that breaks]

Coolant seals are ~$150-200, a good condition plate is probably $25-50.

Did you have a friend check to see if the clutch slave cylinder was pushing the fork? Hydraulics are kind of a pain in the butt.. If it's not moving the fork, try rebleeding them, if that doesn't work just replace both cylinders and the softline [unless it's braided SS or pretty new looking] - www.mazdatrix.com has ALL of the clutch hydraulics for about $110 [I even replaced the hard line on mine to be super sure]

Hmm... General rotary knowledge.. You should never rev it past 3K [or at least 3600] when it's cold. You should rev the engine up regularly [by that I mean REDLINE it at least every 2-4 times you drive it - you can also redline it as much as you wish and the engine if the coolant seals aren't failing, will thank you]

It's an S5 [89-91] so it's difficult to remove emissions equipment [aside from the cat] - specifically do not remove the air pump [it will stop opening the 5th and 6th intake ports if you do]

You probably shouldn't run a straight pipe exhaust... Police don't tend to like it, and it's probably bad for your hearing too ^_- If you want a nice, good looking, well performing exhaust, IMO Racing Beat [www.racingbeat.com] is really the way to go. Super durable, great sound, big performance boost over stock..

If you want to do a turbo swap you'll probably want to get a full drivetrain [the NA transmissions are quite a bit less durable, but if you're not boosting it like mad it will probably hold up] Engine, transmission, driveshaft, diff, halfshafts.. Will all bolt right up [well, the engine will need just a tiny bit of wiring help] you'll also need turbo ECU [engine computer], boost sensor, and throttle cable.

Yea, $900 sounds like a better deal than I got on my vert. ^_^'.. [$1400 with throughly bad coolant seals]

thnks alot ... this was alllll very helpfull im going to check it all tomorrow and yea the fork is moving so im thinking it might b the pressure plate or the throwout berring..... but if im going to rip the motor out then i might as well do the clutch disk pressure plate throwout berring and it all sense something is messed he obviously didnt kno how to drive... yea the kid over reved it alot i could tell.... hes kinda retarded lol didnt know **** about cars..... but thx for this info im going to look into alot of this tomorrow...




can anybbody get me a exact temp cuz i have a tower temp gauge

like whats hot warm over heting ..normal?

There you go ^_^

Well, you can't really over rev it unless you're hitting the rev limiter [it cuts ALL fuel to the rear rotor], when I was driving my S5 vert around after the rebuild and breakin, I shifted at 8500RPM when I wound it up B) Good times.

Ahhh there we go - I was being stupid for a sec. Yea cold reving is bad.. For any car, esp these. ["It's unthinkable" That's my excuse XD] - btw technical reason for it being worse that I always keep in mind: you have alternating aluminum and steel for the main pieces of the engine, so it can't expand equally.

Ben.farnath>> Well technically a body kit lowers the value of an RX-7 unless it's literally show car quality..
[and here's where I mention that I hate body kits/slamming - I think Mazda's designers are far better than some aftermarket designer trying to make it look all crazy ^_-]

i fully agree on the bodykit. its not my preference. my fc has finishline rear bumper lower, standard sideskirt copies and a front lower lip and its staying all s4 not a s4/5 mix up (i even sold my series 5 tail lights that came with the car to buy series 4) . lowered but not rediculously. factory styling for me. what i meant was he bought a whole car for 9 hundy, here in nz the kit alone woulda been more than 9 hundy.

RX7s are behind in aftermarket support compared to 240s. You just wont see that parts development /discoveries that are still striving in the 240 community. but are rewarded with not having that theft interest rate like 240s. And an FC like yours with the kit, once it has some better wheels on it, can stand out pretty big from the 240s.

I'm not quite extreme enough to stay away from S5 parts... I have S5 tails, seats, and center console surround on my 87' [better looking, better holding, much more durable - respectively]. My car's lowered about an inch [RB springs], and it does have R32 GTS-T wheels [R32 wheels are the best looking wheels in the world IMO XD]

Wow.. Yea, every time Bumpstop mentions pricing down there it sounds awful.. >_<

Body kits... Usually just look bad to me, and I don't like things that permanently modify the body [It pained me to do it just for the S5 tails..] I think the only appearance things sorely missing from an S4 are the S5 tails, and the S5 nosecone changes.

Slamming... Just isn't practical anywhere I've driven, which is why I can't understand how anyone else can do it [our roads are pretty good for the most part, but there are far too many driveways that change angle too much - once I even bottomed out on *stock springs*!]. Other than that, it just looks like it's broken [makes me think of my uncle's old towncar with blown suspension, lol...]

I try not to complain much, because at least it's still rotary. XD

Btw, your 240 looks pretty clean.. Does it still need paint on the body kit? Might be the pict but it doesn't look shiny like the rest. [It looks like you actually take care of your car - most 240s around my area are either hideous or automatic.. lol]

good idea but would it risk clogging the cooling system? btw nice 240!

search the forum for irontite, seems like the sweet stuff to use.
