The main thing I'm interested in is if you can get the TPS to work correctly. The throttle cable might be an issue as well unless you're using an FD throttle cable???

I have the pinout diagram to tell me what pin does what, its also somewhere in this thread, so i am hoping that works. The Throttlecable problem is gonna have to be worked out once i get it all mounted and see if the FC cable will work. I am trying to findout when the FEED kit was made, what cable they used.

Good deal, Keep us updated.

StarScreaM2k1 - No I don’t think you got any misinterpretation other then the post was not geared much towards you and more towards the comments and hate posters grasp on the concept to your mod. If you were NA I would be busting your ***** more, personally being boosted ehh rotarygod has said it twice now they are forgiving and you wont notice a damn probably over your stock setup. Would I personally do an adapter? No that’s not my style I would have fabed a LIM for it but I don’t hate upon you for an adapter. In a way of my opinion it is a half assed mod but the setup was not designed to be a all out performance tune and show car setup so why spend the 1K plus to have one fabed. Yes the runner lengths and bends change your throttle response and tq curve however this is exactly why I feel the way I do about intake and port mods. I feel throttle response and curve is more important then the final number at the end of the dyno.

If I were to fab you an intake mani you would be expecting to pay around 1,200 to 2grand. The time involved and machinery is very intense and is not cost prohibited for many people. This is simply a good thread to share enlighten to many people about how mods can potentially effect the motor throughout.

You're probably right, but it's not because I don't understand the subject matter...

You still seem to be implying that throttle response and the torque curve will be negatively affected by this mod, yet you offer no explanation why. Why are you so convinced that this UIM can have no benefits on an FC engine, despite the fact that Mazda obviously felt it was a better design?

This goes back to my question which you still haven't answered. To remind you, what re-engineering do you think is needed? What exactly is it you think has to be done to a 13BT before you can justify using an FD UIM?

If I was to do something as involved as this I would want to know exactly how much improvement it made. There are other ways to measure the effects of mods besides a dyno (e.g. acceleration runs), but there's no doubt that a dyno is the most accurate way as long as you're using the same dyno for before and after measuring. Two overlaid dyno curves will give you a pretty clear picture of any changes.

True, but in this case that doesn't make much difference. Measuring power at part throttle is of little use or interest to anyone. If you assume that this mod increases VE a little (just as an example), then when cruising you would probably use a fraction less throttle to maintain the same speed. But would you even notice? No, and you probably would've care much either.

One thing that before and after dyno curves will clearly show is where in the rev range gains are made. If a particular mod only gained you 5% peak hp, many people would say you didn't achieve all that much. But if the dyno curves also showed that you gained 15% at 4000rpm, then that is a far more significant improvement, and will dramatically improve the car's real-word performance, even though peak power is not changed much. Lot's of people don't seem to get that, but I digress...

You have 30 minutes to edit your post.

Go back and read post #37.

Thx for the reply, yes I am sure the matter exists in the way I relay my information and you understand it and not the matter of your knowledge on fluid control as I know its exquisite.


No not at all. I have a notion that because of the possible that it could cause some flow intrusions, but I have not seen his plate inside and out.

I was only and simply implying that changing this aspect of any motor will have effects in this category. Not that his will indefinitely have negative effects. If he was NA I would be as stated much stronger feeling on it will have negative effects.

Both the 13bT as we are using here and the REW are very similar. In consideration to Mazda they designed each intake to work best with each application thou similar there were some forced induction changes and port timing changes. I believe there is cause to see a change in some type of performance but I am honestly not certain on his motor it will do much.

Perhaps he has changed the port timing and the new UIM could have a drastic benefit. This is all possibilities. As I said before it was to make aware of how changes can effect the motor. As for his we will have to wait and see. As far as drastic changes I am skeptical but his was not done for any type of noticeable performance changes. His mod accomplished exactly what he wanted.

Update: Well not much of a update really. Car is off the road for winter. Finally got the Greddy IC Kit in, now thats for a FC, NOT FD. So rather then having to source out a greddy compression Tube and fab up a pipe to work with the FC kit, i think i can make a plate that would work with the FC TB adaptor and the FD TB just to change the mounting so i can mount both. It was brought up to me before about having injector bungs mounted on the adaptor plate, and i been thinking more about that lately. I am thinking to go Alcohol Injection, so maybe have some holes or bungs or whatever for that, anyone have any thoughts on that? Anyhow, just giving an update

Ummm.... so about those dyno results....

StarScreaM2k1

sharingan 19- I sold my FC. I have other obligations that i have to tend to. (last year of uni and then hopefully going to LAW school). So i cant exactly keep blowing wads of cash on the FC anymore. Since i live in Canada i need something i can drive year around, and has more uptime then down.

ePH C freak- I am actually selling the setup, if you want to continue it...you can buy it and go from there.

Actually anyone who wants to buy it let me know, i'll sell the LIM, UIM, ADAPTOR PLATE, TB and whatever information i have and help ya along with it as best i can. Sorry, but i wanted to continue this project, but my career and education have to now take a front seat or rather i gotta get something thats not as demanding to mod/maintain and i can drive year around.

I wanna rice it up too!

No seriously, If I were to use the FD UIM on my S4, since its higher, I would presume that would enable the use of the NA TB elbow and clear the oil filler tube so I can connect it to my FMIC, right?

I just hate the stock elbow for an FMIC and cant find the freakin greedy elbow. I'd love to use the NA elbow, its perfect.

Just some food for thought...Here is a pic of my setup.

PM higgi on here, he makes replicas.

They fit around the stock oil filler neck and oil filter. OR you can buy an actual greddy compression tube from www.rx7.com
