I have a 1991 Ford Escort LX SEFI 1.9 liter engine and it is turbocharged and I was wondering if a 1983 Ford Escort 1.6 liter cylinder head would flow better than the cylinder head I have right now? Also could I even get a 1983 Ford Escort 1.6 liter cylinder head on my 1.9 engine block? I remember John Smith swaped his 1.9 liter HO cylinder head for a different one because it flowed better. And I wasn't sure if it came off of the 1.6 liter Escorts.

What about the 1.6 liter cylinder head that wasn't turboed? I am considering buying a brand new 1.6 liter cylinder head that was never bolted on a engine block. The cylinder head part number is RFE3EE-A7A. Do you know if this was the turboed 1.6 liter cylinder head?

Now that i am unsure of. I found a complete 85 turbo that i bought out of a jy here. I had it taken to the house, pulled what i wanted off it. And then called the jy to pick in back up. Do you have a 1.9ho head you can look at? The 1.6L head, if its the same as the turbo head. Will have exhast ports bigger than the 1.9ho head. The valves will be bigger as well. At least the exhast valves will.

Nice catch iscorticus.
But the SPI head does flow better than a 1.9 head. And it does have a cam sensor. And it does use the same head gasket.
But it will lower you C/R, and If I remember right you have 8.5:1 pistons. So you would have more like 8.3:1 it would be a slug untill you get some boost spooled up. But you have a RS mani right? So your turbo has the potential to run high boost.
Hybrid 1.9/2.0 @ 20 psi has a nice sound to it :twisted:

Sure does...
I have a couple of HO heads at my disposal... I have been down that train of thought a few thousand times.. and I still ahve no idea how it would affect compression, if I could get a cam reading some how.. oh,a nd the idea of using the HO intake and such is a turn-off, the SPI has a really nice intake system, comparetively... (cept the TB which I may be able to get a couple of if anyone's interested)
