CFI definately has smaller valves the the HO. I have both of them sitting in my storage unit.
indeed it does. my Ford techdata is wrong then.
hard to believe that the SPI valves are even larger than the HO, where'd they get the room? well i spose if the cc was larger...hmm
As mentioned above, you can get 1mm larger intake and .75mm larger exhaust valves for the 1.6 head, which will fit into the 1.9, provided the seats are enlarged as well. That would make the valves about the same size as the SPI. However, since the SPI is a D chamber head, I wonder if it actually flows as well since the valves are a bit more shrouded than the HO head. Maybe it doesn't even matter.
WOW! I'm glad I read this post. You know the white piece that goes in the clip for the CPS? Yeah, mine disappeared on the last head replacement, so it's held together with Electrical tape... So my car sometimes sputters at idle... now I'm thinking that the connector might be loose.

one thing ive learned over the years with this car is to keep as much stuff stock or in as close to stock running or operating condition as possible.
The cool thing is that there is alot of stuff that can be changed using other vehicles parts. Keeping something stock can be boring. Modifying it can be desatorous, (sorry, bad spelling) The thing to figure out is the line between the two to have a [email protected]$$ car!
when i say keep things stock.. im not saying dont modifiy the car at all..
honestly.. MSD wires and coil pack didnt do squat for either of the 2 escorts i had them on.. eventually causing issues with both of them..
stock plugs, wires and coil isnt boring.. it works. no need to upgrade really.
the things i say to leave stock arent going to make a badarse car if modified anyway..
people are tweaking temp sensors, cutting out cats, sticking platinum plugs in, etc... and none of that helps, usually ends up with a post in the engine tuning section about why it isnt running right..
Totally agree with ya. If your gonna do it, do it right. Unless, the parts to keep you from frankensteining your car are not availible, then you do what you can at YOUR OWN RISK! Now, I don't exactly mean not to turbo the motor, or not to Hybrid it (1.9/2.0 SPI, .... ) Just driving it seems a little boring. On the other hand, don't cry when your SCREW it all up!
you dont know how many times over the years id do something to one of my cars.. think "aw yeah! this is going to be awesome!"...
only to have to put it back to stock to see if the problem that came up then goes away.. and it does..
i guess thats why automotive engineers get paid so much for those fancy degrees.
I don't think your following me on this one.
I mean to say, I don't disagree with modifying your Escort, shoot! I plan on modifying my own. What I'm saying is don't expect it to work perfectly afterwards. They were built the way they were for a reason, when modifying things, they break. Like with a Honda, my friend has been through 4 motors doing his "Trial and Error" method with his SOHC Turbo project, and he expected to go through a few. Now that he's learned from his mistakes he's made, made the adjustments to fix the problems modifyied this and that for upgrades, now he's ready to build his motor for the power he's putting into it and hopes the motor blowing days are over. And yet, even though you build the crap outta it, its still going to go eventually. all cars die eventually!
