Questions.FD upper on a TII.

[misterstyx69]

This is the scoop,so far.
Yes,I know that you can use a FD upper on an FC,providing that you use the Fabulous Spacer that everyone is Talking about.
What they are not Talking about is which Throttle Body they are using.
Which Throttle Body and TPS is used when doing this Conversion?.
Why you ask??.Well I am going to Use a Stock harness for my Swap.I would like to anyways.My "dilemma" is,If I have to use a FD throttle body,then how will I wire up the TPS?(I need wiring info).OR, 1): can a FC s4TII TPS be attached to an FD throttle body?.or 2): will an FC throttle body Bolt on to an FD upper manifold Without Isuue?
That is my Situation.I hope someone here can answer.I am getting the old " this has been covered numerous times" on the Other Forum,and Frankly,I went through alot of Stuff,but I just couldn't get the Specific answer.
Thanks Gentlemen,In advance..STYX!~

If I have to use a FD throttle body,then how will I wire up the TPS?(I need wiring info).OR, 1): can a FC s4TII TPS be attached to an FD throttle body?.or 2): will an FC throttle body Bolt on to an FD upper manifold Without Isuue?

It is highly recommended to get the FD TB also.
Since you're using the FD TB, you can use the stock FD TB tube or get the GReddy aftermarket unit.

It's going to be a PITA to adapt the S4 (or S5) TPS to the FD TB.
It's easier to use the stock FD TPS and splice the lines.
The FD TPS has both a narrow-range and full-range TPS sections, just like the S5 TPS, but the TPS physical design is different.

As with the TPS, the FC TB is going to be a PITA to adapt to the FD UIM.

So...
It's easier to get the FD UIM, TPS, and TPS plug to make this an easy swap.
Keep in mind that a brand new FD TPS is $300+ from the Mazda dealer!

Thanks alot TED.I appreciate the Reply.I've never Seen a FD TB or TPS,so I wasn't sure If it was even possible to adapt anything.I wouldn't mind some Info on where to get Wiring for the FD Tps if posssible.Then I will compare it to the S4 Wiring and find out what I have to do.
..Oh!..I was just mentioning this Swap,and then out of the Blue,someone says that Though the Swap is asthetically The better,The HP gains are just not worth it.Anyone have any Feedback on that.Thanks again.STYX.

I am wondering if anyone can tell me How to wire the FD TPS into the TII(s4) harness so I can fun the FD Throttle body.Thanks.STYX.

make sure to note that you will have to rig up the omp rod to the FD TB if you are still using the OMP.... or premix

You know, I used to be kinda weary of premixing, but my pump, oil injectors, and lines all failed.

I didn't have the money to buy 4 new injectors and a pump, so because I was planning on an rtek anyway, I just chose to get the block off kit.

Another bonus is that it further helps eliminate clutter and potential vaccum leaks.

If you have an S4, you do NOT need to buy the rtek chip in order to remove the omp system, also, Banzai Racing sells the best "kit" to do this for a reasonable price that includes the plate, bolts, and the pipe plugs n shit to block off your injectors. I got one, love it!

I would like to try this and finally settle the debate between fd and fc uims. I know some people made a spacer, anyone know who to get one from? I know you can weld inside the ports and then grind them to match, but thats to much work for me.
I never really looked at the fd uim and tb, is there vacuum ports for the brake booster and the rest of the lines?
I'm still using the bac valve, does the fd have one and where is it?

[misterstyx69]

UPDATE on this:.I got the FD upper and manifold,Throttle body,and the Fancy Spacer..I hope to get the engine in This summer.
along with trying to do this,I have a Body kit to install,Fuel pump,TII diff and axles,Camber adjuster,Finish the Stereo and gauge install,front mount intercooler installation...and I am sure I have forgotten something,but anyways,If anyone is reading this,I need an FD greddy elbow!!!!..(no hurry..haha!).Cheers.
OH,I still need INFO for wiring a FD TPS to the FC Harness.

Link to this fancy spacer?

[misterstyx69]

If you go to my "other" thread located in the Sec Gen Specific Section of the "rival Forum" you should see where some Guy has taken it upon himself to actually PLUG some Spacers and SELL them on my thread..
