All the blocks are pretty much the same (even the turbo block), except in 1988-89 when they went to smaller main journals in the block/crank, in 95 Ford did away with the hole for the distributor in the block. So you can use a block up to 1994 (as long as it has the hole for a distributor), and any 4 plug head will bolt on the block. The 8 plug heads have totally different intake ports so there are no after market intakes that will fit those heads. You can get a factory roller cam from 1988 and up Ranger from a salvage yard, it's a lot cheaper than getting a roller cam setup from the aftermarket. If you decide to go with 10.5 compression you can go with cast, or hyperutectic pistons (I've done it, but you will need to keep the engine out of detonation so you don't kill pistons). With todays pump gas I wouldn't go more than 9.0 to 9.5 compression. If you raise the compression by milling the head, or dome piston check your valve to piston clearance closely (also depending on what cam you decide to use) you will turn a non-interference engine to a interference engine which will bend valves or worse should the cam belt should break. A better alternative to milling the head would be to get the crankshaft out of a 97-2001 Ranger with the 2.5L. The 2.5 has a longer stroke than the 2.3, the only other difference is the 2.5 has a shorter compression height (the 2.3 and 2.5 use the same connecting rods), the extra stroke will help raise the compression.
I don't think that the projection will have too much cfm because the injectors supply the fuel, it's not depending on the ventury like a carburator has to to supply fuel

Thanks for your insight. i have a factory roller setup in a mustang head and a ranger 2.5
complete engine with low miles. i actually got to drive the ranger engine just before i pulled it to do an electric conversion for a friend so i know its sound. is there anything special or version different about the balance shaft that drives the distributor?

When Ford did away with the distributor hole in 95 they moved the oil pump to where the auxilliary shaft that used to drive the dist/cps. I haven't had a chance to get a good look at the 95, and up 2.3/2.5 blocks with the relocated oil pump (there hasn't been hardly any of them in salvage yards like the u-pull-it types around here).

well i hope to tear this one down in a few weeks and if i can figure out how to attach pics to the post i'll break out my calipers and post some. it looks like i'll have the johnny cash Cadillac version of a lima before i'm cruising it. do you think 250hp is a reasonable goal for this engine in a daily driver or am i being unrealistic?

Any more than 200hp without a turbo wouldn't be very daily driver "friendly", you can run 200/350hp with a turbo (just by adjusting boost pressure) and still be a good daily driver.

Hey Kenneth, Hey Everyone,
I just wanted a confirmation about some things said on the original post, and my questions, just to make sure before I make a move on real parts. This is about the 2.0. Is there an EAO and a non-EAO 2.0 (70's era, not later)?

The 2.3 head (and therefore intake, exhaust, Ranger roller cam, etc.) fits the 2.0 EAO?

Is the bellhousing bolt pattern the same for a 2.0 and 2.3, therefore allowing a 2.3 T5 to bolt to the 2.0?

A 2.3 Duraspark will work on a 2.0? Did the 2.0 ever come with a Duraspark? I'm thinking no because it was older.

I'm planning a high-MPG build and was leaning toward a Toyota 2T/3T hemi 4-banger. But, if I can swap 2.3 parts onto a 2.0 then I'm leaning ford again.

Thanks,
Kurt

Hi all.. Very informative...
I am building a 2 ohc (pinto) its the european version so i guesse its the 2.0 EAO, we have 3 choices of block the 2.0 the 205 and 200 block ,the 200 block being the best,,

I was also thinking if a different head would fit the block.. i think from memory the bore centres are 4.014" spaced..


Any ideas or advice ..cheers madragon

There is a long standing SCCA racing class called Sports 2000. The cars use 2.0L Pinto engines with limited modifications allowed. Shops and racers in that class, and people supplying them parts and services, know a lot about the engine.

None of the 2.3/2.5, and the 1983-1988 Ranger 2.0 (Lima) engine parts will not interchange with the 2.0 EAO engine (the 83-88 Ranger 2.0 is a de-bored 2.3, and the ranger 2.0 block can not be bored out to fit a 2.3 piston). The bell housing bolt pattern between the 2.0/2.3/2.5 Lima engine is slightly different from the 2.0 EAO engine (The EAO engine was also available in Europe in 1.3, and 1.6 displacements, but they were never imported to the U.S.).
Fords initial plan for the Lima engine was to make all the parts interchangeable with the EAO engine, but due to the newer manufacturing technology at the time in which the the Lima engine was being planned Ford determined that it was impractical to design the Lima engine to accept parts from the EAO engine.
The best way to sum it up is that the EAO, and Lima engines are like identical twins at first, but once you get to know them you will notice minor differences between the two.

I'm retro fitting my 87 2.3 to carb/duraspark II. The guys at the parts store only know year/model. So.... what year/model will get me to duraspark?

Kinda OT but here's a pic of my gas sipper. Has the 2.0 and a 4 speed in it currently. Gets right around 31mpg!

Planning on building a hot N/A 2.3 for it soon and strapping the T5 to the back of it.

I tell them I need one for a 1977 Mustang II with a 2.3L engine.

Thanks for the help with the 77 reference. Amazingly, Bumper to Bumper had everything but the rebuilt distributer on the shelf! While looking for an ignition harness, I fell into a 79 mustang with enough parts for a good start on my second retro motor.

I'm planning, at some point, to go back to 8-plug heads. To that end I've picked up a megajolt spark box and pieces for EDIS. The megajolt has provisions for hard and soft rev limiters... Which brings up the question: What is a realistic redline for a motor set up with Ranger roller and stock rods?

With the stock Ranger roller cam, and stock valve springs the valves will float around 6000-6500 rpm's. With prepped rods, good rod bolts, and stronger valve springs 8000-8500.

Uhhh, is the early Capri and the early Pinto 2.0 the same engine, and are they the 2.0 EAO?

Yes, the only difference in the one used in the Capri it that it had a rear sump oil pan, Pinto had a front sump.

Can the 2.0 head be shaved to raise compression and/or are there relatively inexpensive aftermarket pistons? I'm thinking about 10.5.

I had a head milled .070" to get a 10.5 compression ratio on a 2.0 EAO, but with the cam I was running it was no longer a non-interference engine (I used to change the timing belts frequently). Any time you deck the block, or mill the head on any of these engines a you also need an adjustable cam pulley to get the cam degreed back in correctly. There are no inexpensive aftermarket high compression pistons for the 2.0 EAO.

Not high compression, but rockauto.com has Sealed Power pistons for ~$40 each. They don't seem to have pistons for the Toyota 3T/2T, which is another engine I'm considering. They do for the Geo 3-banger. So, that's good to know.

I can't see forking out the big bucks for aftermarket high-zoot pistons for my project.

An adjustable cam on a 2.0 EAO might be good for the goal of high-MPG.
