Hi guys!

I wasnt here for a long time.
For those who doesnt remember me, my name is Andreas and i got my fd via ebay from england in september 2007
Well, description sounded really good, but when i stood before the car, it was a real mess. Engine idled rough, battery was near dead and so on but, i drove home with it for over 800 km without a problem.

But then it began, problems problems problems. I started a new topics because i was an absolutely noob with rotary engines ( and still am ).

First, a self called rotary experts near my hometown said he will fix my problem with the idle and i got him the order to replace ALL vacuum hoses. Well, he replaced only the one i already put out, fixed hoses with glue to the plastic, were the nipples broke off and and and.
So i paid a lot of money and the car ran worse than before. So i said to myself, i wanna learn to fix the car and do it myself.

So i replaced the hoses of the rats nest again, the car ran but i had no power. Compression of the engine was on minimum too, so i decided to rebuild the engine.
I did it with the "do it yourself dvd´s" ( 3 different ones ) and the help of mazda malloy ( parts delivery ).
I also eliminated the sequential and went non sequential.

So here my rebuild list:

- engine rebuilt
- heat exchange core ( under the dash panel ) changed
- front mount intercooler ( still to install )
- ARC air filter box ( still to install )
- engine damper ( still to install )
- original Bilstein dampers and springs ( still to install )
- non sequential kit from banzai racing ( installed )
- 3,5" downpipe ( still to install )
- catalytic converter ( installed, midpipe went off the car )
- stock rear muffler installed ( blitz nurspec is waiting for after making the car street legal )
- european headlights installed
- fuses, hoses, ....

Off course, the lazy bug bit me often, but i had some problems too, like end of relationship, like i wrote the self declaimed expert, changed my apartement 2x, car had new problems ( and when you fixed it, you had 2 new problems again ... ).

So first of all, i have two little questions. My problem, i didnt shoot enough pictures and wrote down informations, so could you help me here?

1.) Where do i mount the engine harness? There are 2 clamps to fix the harness to the chassis, one is between the coolant hoses for the heat exchanger and the 2nd clamp is near the transmission.



2.) Where do i mount the ground cable ( which comes with the connector of the CO2 sensor ) ??



I contacted my former japanese teacher for my problem with the japanese instruction manual ( for the front mount intercooler )

Thank you very much for supporting me to finish this long project.

 

as yours is a JDM, i cant answer on the engine harness.

on the grounding, the engine and the chassis is part of the same ground circuitry, so using either a bolt on the engine, or a chassis bolt with good connection should be enough?

Keep up the good work, man! You`ll have it fixed in no time!

 

Thank you for your answer.

Yeah i forgot to tell that i own an JDM FD.
I thougth the same about grounding and i will fix that ground wire to the engine block. There is a 2nd ground wire near this one on the picture and i can remember one was attached to the transmission.

Well, i think i have to search for JDM engine room pictures too. Damn, i wish i would have made more pictures at the disassembling...

PS: Thx for your good wishes!

 

Small update:

I put everything together, but my wiring harness is a real mess...

I tried to start my engine, but it wont crank. I had a charged, good battery and starting help from external generator, but i only hear a fast tick tick tick. The starter is getting hot by the way.

So i turned my engine manually, and you can turn it without problems - well it seems my rebuild is ok so far.

Let me ask you that too, i did the rich mans non sequential, but i dont know at the moment if i need a PFC for going non sequential or if i already can use my stock ecu?

 

You can use the stock ECU with non-sequential, however if you removed solenoids for the non-sequential switch then you may need some resistors in place to trick the stock ECU into thinking they are still there. That won't keep your car from starting though.

 

Ah thx a lot, Mahjik. I let the solenoids under the UIM and connected them to the wiring harness ( to avoid error reports ).

So i have to check why my engine would not crank... ( again )

check that out if you already havent.

 

Thx a lot, i read that article allready in the past.

So, picture 13 - 15: I put the original solenoids to the connectors, but did not plug the holes on the solenoids. But i guess it wont make any difference because the ecu will be happy, when the solenoids are connected.

22 -24: I did not remove the thermowax and cold idle cam, but i allready bypassed the coolant hose, so no coolant will go any longer through the throttle body manifold. Is it ok so or should i really remove thermowax and cold idle cam?

37: I didnt port that wastegate hole, but i will not run my engine without the catalytic converter. 3,5" downpipe and my blitz nurspec exhaust will be installed, so i hope i dont get any boost creeps!
