Howdy folks,

How does Gude modify the Bullfrog throttle bodies for the 2nd gen GTs? I picked up a second car with the 1.8, and have the throttle body off of it.

Do they merely port it slightly, and polish it? What exactly is done?

Hey, Ryan, sorry that I have been absent of late. I am going to try to get back on the board a little more often.

I worked on my throttle body myself and found some missing CFM. I went a step shy of a true rebore, since I didn´t want to go to the hassle of making a new throttle plate. Instead, I decided to thin the throttle plate shaft as far as I felt was safe, to remove the bore ridge just before the plate, to open the throat as wide as possible and taper it smoothly to the throttle plate. I have some flowbench numbers for you, but I can´t find my binder, just yet. If I find it tonight, I will post some numbers for you. I also have some pics, both, before and after, as well. With all the other goodies I did at the same time, I can not say if my throttle body work made a noticeable difference, but the flowbench numbers were quite good, relatively speaking. I have yet to put my Kill Post up, but I just ran a dead heat with a buddy´s Audi S4 from 70-120 and from 15-100, so I am making some power with all the mods.

Oh, what do you think of the Tokico S/R´s paired with the Eibachs? I am torn between those, for the price, and the Koni red inserts.

Um, the car goes boingy boingy?

Actually, the tokico and eibach combo is awesome, for my use... My car is a daily driver, and for the highways and biways around Ottawa it is great. Speeds increased through all corners, and now I can get a nice little tire squealing four wheel drift going around some corners.

All in all, a very balanced package, accentuating the strength and how solid the 2nd gen Escort chassis is.

Hope this helps. If you are planning any serious race excursions, I would suggest either more drop (Intrax, etc.) or possibly even a ZX2 coil over kit...

Boingy, Boingy, indeed! When I first made the switch, years ago, I felt the same way. The ride was compromised a bit more than I had anticipated, but it was completely livable.

I´ve had the Tokico Blue/Eibach combo for 135,000 miles, now, and have never been completely pleased with the Tokicos. The valving didn´t seem quite strong enough for the Eibachs, and with the bazillion miles I have on them, they are definitely mushy. I am still questioning whether the Tokico S/Rs will be stiff enough for my liking. I toyed with the idea of the GC coilovers, but with shocks, struts, plates and competition bushings, the investement seems a bit steep. If I stick with the S/Rs and the Eibachs, the expense will be more attractive.

As for my binder, I have, yet, to find where my wife has placed it, but, rest assured, I will not be defeated.

Thanks for the input, Ryan.

Marcus
