Focus 2.0L SPI Swap to 1.9L SEFI

Focus Engine swap. 2.0L SPI to Escort SEFI 1.9L

I know some people are going to say I am nuts, but I have more time than money and horsepower is not a big deal.

I found a great deal on a 2003 Ford Focus SPI 5speed with a dropped valve seat for $350

I bought a 92 escort for $200. Took the parts I needed and scrapped out the rest of the car for $175

Things that needed to be modified on the 1.9L block.

Waterpump from the spi. one bolt hole needs to be drilled and tapped.

Support bearing for right hand drive axle. There is one boss on the 1.9L block that can be drilled. The other two are mounted with a piece of plate steel from the factory 4 bolt engine mount bolt bosses.

Passenger side engine mount needs to be custom fabricated. There are three 10mm threaded holes in the factory 1.9L head. I used those and strengthened it up with a brace to the accessory bracket.

I decided to use the 1.9L intake manifold. The TPS and IAC connectors need to be swapped out.

The SPI fuel injectors are shorter than the 1.9L. I used the SPI fuel injectors because the wiring plug wouldnt have to be modified and the fuel ratio should be kept the same. I had to redrill the fuel rail .4375 inches from the factory hole for the shorter injectors.

The fuel pressure sensor on the SPI fuel rail. I modified this to work with the return side of the 1.9L stock rail.

I swapped the oil pans, but I dont think that I would of had too.

The stock SPI thermostat housing bolts right to the 1.9L head

I know I am a cheap skate but have a nice running, ultra reliable car for less than $500.

If anybody needs info or pics let me know

A buddies got a '91 Escort and plannin to do the same in reverse order. Escort 1.9 was $100 and got all the needed 2.0 SPI parts for $350. Just got to find the time and patience. I'm interested in how your project turns out.

Should be an easier swap than what I did because you wont need to worry about the passenger side drive hanger bearing, Or engine mounts for that matter. You may want to find a 10mm tap to rethread the holes on the SPI block that were not used, but you will need for your escort motor mount. You may want to run a escort SPI intake manifold though. I have one available if needed.

wait so a 1.9 will work in a spi? id consider doing this swaop because a 1.9 with a 2.0 head drops compression quite a bit and makes for an excellent turbo motor

I wouldnt see a problem with doing this. You would still need to fabricate a drive support bearing bracket as the 1.9L block only has one boss. I have a small machine shop and may start making brackets for engine swaps. There are a ton of focus spi's that are going to the graveyard that could be fixed up into great little cars for less than $300. In my opinion the 1.9L was a better engine than the 2.0 spi.
