I usually don't like ported drive by wire throttle bodies, they cause a ton of idle issues on other cars. If you get it and we start having stumbling issues it will be the root cause!
Yes but this one is only "optimized", not really bored out to a larger size. Only areas that are massaged are the inlet (knife edging the leading edge of the throttlebody which should not change anything except smoother transition into the throttle plate), thinning the plate shaft (which will change inlet surface area a fraction) and removing the exposed screw heads. I can understand how going from a 52mm TB to a 60mm or 65mm TB might have some issues with FBW TBs, although on the SVT Focus it was the shiznit (going from I think 60mm to 65mm). We can certainly try it. I wouldn't expect much except for an improvement in throttle response and possibly a hair less pressure drop due to less restriction on the intake side. One thing I learned a long time ago is that there is always room for improvement on mass produced parts, including aftermarket mods. This is especially true with OEM parts where production casting is more "bean counter" sensitive than to overall "performance". That's why purpose/hand built engines (and blueprinting) provide nice boosts in power and longevity.. where every part is weighed, matched and machined for perfect fit and performance. While modern day machining processes have improved dramatically in the last couple of decades, any mass produced and put together by a "machine" can usually be improved on with hands and eyeballs. lol. This is pretty much what I did for 16 years, albeit not in the automotive industry. [:)]

I didn't read it thoroughly, if it is only "optimized" you can just send me your throttle body and I'll put it through my CNC lathe and clean it up and turn down the shaft.

Yes but then there would be down time for "Silver Bullet" hehe.

Basically what Cordova is doing is selling a new (or in some cases used) TB and then doing their work which adds $49.00

So maybe I will just buy a new one and send it to you and have you do your work if you are interested in that sort of thing. Heck, I wouldn't even mind letting you use it on your car to look at how the ECU responds and/or to look at tuning for it. [wrenchin]

Let me check with Ford to see how much a new TB is my cost, post back soon.

You're welcome, sorry for the first reply I just thought you were looking for what issues COULD happen, not why. Cheers!
No problem. Cheers right back at ya.

Yeah, but what is your time worth to make the modifications?
That's the most important question of all. It would be much more difficult to do the mod if you have other commitments (tunes, selling parts etc etc) than if you only did the TB mods such as Cordova does. I could imagine *IF* it works good, there would be alot of demand for them. That demand means a fair amount of time would be need to be invested in it.

I initially thought to cut the intake throat off the FoST and plasti-weld (is that a word?) it to the FiST but the polymer content has to match exactly for it to hold (so I've read). Looking down the inlet side to the FiST intake you can see about 8mm worth of thickness. Do you think if the poly intake inlet area was heated correctly that a cold stainless pipe (the same 57mm as FoST throttle body) could be pressed in?

I can get us a a TB for about $70+shipping.
Pick it up, send it over, and I'll do some testing on it and send it back to you.

Wouldn't be a problem to put it into production on my end if it works.

I would be willing to consider this if you guys (MAP) did the testing and was able to show this actually does work...The Cordova "claim" that another vehicle tested showed a 4~6hp improvement and therefore drawing a conclusion that this will show similar gains on a FiST is a pretty weak inconclusive statement...

I'm really looking forward to hearing what you find in your own verification testing...

On my old built Honda's we always used these type of TB's. Depending on displacement (B-series) we would see anywhere from 3 to 6 hp and on all-motor (NA) Hondas that's huge. I've used JG & Skunk2 knife edge and my mechanic would mirror polish by hand. Think of as a velocity stack when you go from 68 to 62mm (Honda) it will absolutely increase air velocity. Interested in seeing how this works in our turbo application.

The $70 TB i mentioned was incase anyone wanted a core to do their own core :)
I'm personally willing to pay these guys, when it gets down to counting beans. For now, I have way too many other and bigger fishes to fry :)
I would like to see someone improve and test one, which is why I offered it at that price.

Cordova throttle body pictures

underside of modded throttle body.jpg factory example of throttle body.png modded throttle body.jpg
The top picture is the underside of the modded throttle body, you can see the uneven shaving/cut.
The middle picture is what the factory Fiesta throttle body (I know it's an older model but you get the idea)
Then on the Cordova throttle body you can see where the center shaft is cut (badly) and flush screws set...
I'll probably just clean this up with my dremel...

It's a crappy mod but just looking at what was done you pretty much can do this yourself... definitely not worth the $160

Take a look at the pictures I posted of the Cordova throttle body... I'm sure you can do something better...
