Whats up everyone so ive been looking for something fun to drive and that I can put alot of time and engery into. An my search finally had a break I'm in the process of acquiring a 87 Rx7. I wont be do anything major off the gate but in the future I deffinately will. but I want to take care of some basic things first. Ive searched the forum as best icould but to no avail can someone post a link the wiring swap from OBD1 to OBD2.

Thanks for the help

Uh...the 87 Rx7 had OBD NONE..( I call it OB Whan Kanoby!)
that is why you can't find any Info on swapping from OBD1 to 2..it doesn't use it.

 

oK thanks for that insight i really appreciate it. By any chance do you know of any threads i can look into, to find more information on how diagnose problem with carshould some appear since it doesnt have scan port? im still studying on my own about rotories but there is still alot i have to learn im reading other threads on basics of rotories.

 

Does it have a check engine light on? It is quite simple to pull codes.

 

Try this.it is about the best you'll get.
Link:RX7 FD and Series 5 Error Codes
Don't let the title fool you..look at the link and then hit S4 Codes.

I go by the old addage that an S4 is either running OK or it isn't,and there is not much to check to fix.( a few sensors and some injectors..piece of cake)
However the "Modern S5" has the electric OMP and can create codes.. that are readable..(good thing too.)

 

Marc- I havent actually gotten the car yet its a deal im working on but i like plan ahead for things as best i can so if something should happened im prepared in advance to deal with it. im doing all the research i can and trying to cover my bases before i actually make the buy. Im still not quite sure what im in for since ive never owned a mazda and for that matter a rotory to. But that is why im on here trying to get any information to be ready is all.

 

That is interesting to know of, by chance do you know of anyone or heard of anyone who has put that same setup in the S4.

 

Trust me,when they say that the S5 was an Upgrade to the s4,they were not really upright and forthcoming.
The engine internals may be lighter but the Electric Oil Metering Pump is a pure Crock of Poop.

Exactly what would you like to do with this car?
The answer to this question will open up a whole new avenue as to what you can get for info.

 

Well this car is going to be a first for me in more ways then one.( my first manual) first real project car to boot and first mazda. But to answer your question this car will be a daily/street the maintence and upkeep wont be problem really because i work for a dealer so machines/ tools are at my disposal. Although since its my first manual ill spend most of my time just getting a feel for the car and enjoy the ride for what its worth.

My agenda for the car

1) CAI/Exhaust/tune
2) Aero& weight reduction/Brakes/Paint
3)Suspension/LSD
4) nit picking (interior stuff and styling the inside a little)
5)New Motor 20B (non turbo)/tune

If I left something out some let me know I want to do this right. So and advice would help if im doing it all in the right order or if should switch somethings around. My thought process was to build the car up so that it can handle the extra horsepower when the new motor gets put in.

 

#5 will got you about 15k...not exactly readily available and cheap.

The main focus would be to get a running car and then go from there.I can honestly say that I had more fun with my N/A FC than the TII,because the TII?,you never know What the hell is gonna go on with it.
The N/A was just a start up and drive the crap out of car!

 

Yea I like the sound of having a mechanically refined engine that runs well without having the boost from a TC or SC for that matter. My plan was the make this car go fast but i wanted it to come from the motor.

 

just wanted to add on to what I said, I am aware of how hard it is to come by a 20B engine right now I am weighing the options I do have(3 routes at the moment) when that times comes but like i said earlier I sure it wont be for a few years before Iactually do the swap still 1 through 4 first. and with variousl msic. parts and jobs that will arise between each/during/and before one project.

 

do you plan to do any performance driving? dont be afraid to be honest.

or will this car strictly be a DD .

you kind of pay a price for owning a rotary.. they are sports cars and honestly are ment to be abused.

20b swap.. welll you can cross that bridge when you get there , But you will be lucky if you stop at 15k

 

Yea drifting is on the mind but that will be further down the road for me and maintence and up keep won't be a problem because I work for a dealer so I have access to parts no problem. But I really wanna do this right so that is why I'm trying to build the car up to handle the 20b swap when the time comes

 

Dispite what you may have seen on initial D , the rotary isnt really a great motor to drift in . all its power comes at high rpms , and its very low on torque . because you are going at low speeds and if you're good you are going sideways . the radiator gets almost no flow while its under super heavy load. so it tends to overheat.

when you overheat a rotary its done .

does not mean you cant.

but its much easier to get a 240 and abuse the hell out of it . or swap a V8 into the rx7 and have torque all day .

 

Yes initial D had a impact on me I'm not ashamed to admit that. I'm glad you gave me that insight but it wasn't a drift run that made me want the FC it was a Sprint that made me want one. Then from there I started my search and looking at different builds and here I am trying to find everything I can about the car. But if drifting can be done in the car where should start looking for successful drift builds any threads in particular I should look at . Or members I should pm about the subject

 

There is a drift section go and have fun there.


I'd give auto-x a try first . It will make you a better driver , its cheap compared to other motorsports .

and its alot of fun. and you will get to learn some control . and accidentally drift . I'd start there.

 

So here are few pics of the car I didn't take to many cause I was sleepy from work and still had hour drive back.

















I apologize if the images come out small I'm doing this from my phone

 

make sure this is the car u want to do all this work to, I have a cali s14 zero rust 291, 000miles, original paint job, still has the pin stripes.lol. started buying all the rb26 stuff and honestly got bored, more cause I have no money to dump in the project and really thought if it was worth doing all this stuff to it. so now im looking for a fd cause its a car I always wanted. just make sure this car is it before u start with all this stuff especially that 20b because it reminds me of the rb26 which is alot of money. just my 2 cents. and do it right the first time.lol

 

I appreciate the advice i know there will be times where itll get fustrating or even boring because it takes so long to get the money for the modifications. But ive made my piece to just work though it, but ill be plenty motivated since its my first in more then ways then one. Like i said first car im that im actually buying, first manual car for me and of course first project car. So im sure this will be something im gonna do plus im busting my butt working as many hours as i can to make tihngs start happening
