Throttle Response??

[Pid_16V]

Never ported the intake manifold so i can't say, though, tbh i cant see it making any difference. If you want to port anything, port the exhaust.

As for the tb difference, again, i dont know, i can only tell you what i know from my own experience with the one i have. I guess you would have to look into it.

You don't happen know which year you have do you? And to just be clear you didn't do any other mods, everything matched up, including cables?

The tb goes straight on, its fixed with four philips (cross head) screws. Throttle cable bracket needs modifying just a little and you need to swap the tps over but thats all.

Mine is a 1998 zetec but they are all the same anyway.

I'd imagine you'd have to use a reducer coupler? Thats a pretty big size difference.

My stock TB looks different:


I had to buy a Focus Throttle cable to connect to my TB.


If your TB looks like mine get an 03-04 FC TB.
If your TB looks like PID_16V's, then get the 00-02 FC TB.

Either way I don't see how you would connect the stock air-box to a FC 65mm TB. You probably need an aftermarket air intake and you need a hose coupler that will fit around the FC TB.
