How exactly is it a bottleneck?

I realize that the response can feel a little slower than traditional cable, but when the throttle is open, it's open. You're not bolting on power if you swap to a cable assembly...

I know I have thought about if you could do it myself. The main reason I want to do it is to improve the throttle response time. I know it bugs me when i go to step on the pedal hard and it takes a second or two to respond.

I think your problem there is the automatic...

With the manual I get a little bit of lag but it's barely noticeable.

Im with mac.mogul on both statements. i personally think that it wouldnt matter if it is dbw or cable. An intake manifold should do you the justice. I dont know if its just me but i feel like this is just a different version of the BIG THREE just sounds more costly.

The DBW sensitivity can be adjusted with a tune. That's prob a better option than going with a cable.

I plan on doing a large turbo setup and research has led me to believe that the TB will be the largest bottleneck on the intake stream with such a setup. They make larger ones for the D23 (Which is what will be going in) and was hoping I could convert the TB so that I can go bigger as well.

And I have an MTX, but I can still tell the delay after driving it for a year and getting used to it. I actually gas a split second before I know I need/want power. It may not sound like much, but in an autox it makes a huge difference; and even though I can accommodate for it I'd much rather have throttle on command.

There's a lot of people on here making big power with the stock TB. Again, a tune can increase the sensitivity of the throttle response. There is a larger DBW TB you can get from the UK. Someone on here installed it a while back. It is pretty expensive though.

I'm not sure now if it'll fit on your Focus' but I can get the 60mm TB for a reasonable price. European Part's prices for the TB's (and prices from Ford Dealers here) are ridiculous if you'd ask me. Are your's FBW??

So if someone can confirm if this'll fit, maybe we can arrange something? The TB's I'm offering are not genuine Ford parts but they're OEM quality, I can assure you. I've got one fitted on my Focus. And, for all I know, European Parts gets them from the same manufacturer where I can get 'em.

Pic's:

The new TB:







My own (55mm) and new one (60mm):




My 60mm fitted:




I can tell you that it really makes a difference. It's not a HP-wonder, but I can tell you that the engine is running more smoothly and the throttlerespons is much better. With some adjustments on the airfilter and -box, it gets even better.

Will it fit? And if so, let me know!

I'm from the Netherlands (Europe) and shipping costs from here are about $ 50,- (i'm not sure about clearance-costs in the States..). I can sell the TB from here for $ 180,-. I'll let you do the math.. :)

I wonder if Ford's Duratec is the same over there!

Dennis.

Also not sure if it can be done to our TB but you could do this if its possible: http://sdbhost.com/cms/docs/TB6optimize.html
