98 2.5 to SC 3.8 v6

[Brain75]

It was gonna bug me on the OBD2 vs OBD1 in the last couple years of the SC T-bird so I did a bit of googling... looks like 1995 the V8 went OBD2, where the V6 was still OBD1. In 1996 all T-birds were OBD2 but the connector was not under the driver it was over on the far left of the passenger space.

so that said, if you have access to a 96-97 (last 2 years) of the SC T-bird that would be the best... too narrow a range for my yards, but you already said you knew where there were a couple SC T-birds so obviously you have more to choose from than me at the moment. (I know of none around). Full ODB2, Supercharged, no PATS (I don't think), might have to do a dakota digital sender to run the speedo - dunno if you will have to, but there's a solution.

The SC was only built from 89-95 and only came as EEC-IV, never OBD2.

so the last 2 years of t-birds were all non supercharged... bummer... guess I misread that some where.

96-97 were available with either a 3.8l NA or a 4.6L V8.

microsquirt is a lot cheaper... don't know what all you loose - seems everyone goes mega..

I'll look into that.

If you want a SC motor, start with an SC motor. Do not start with a RWD motor then add the supercharger later. There no internal parts it common between the SC and the RWD engines… heads are different, block is different, not even the bearings are the same.
I use the terms SC, RWD, and FWD for the different blocks because those are the terms Ford uses for the 3.8L. Those are cast into the block. The supercharged heads have SC cast into the top corners next to the valve covers.

Correct thou art oh brother. Was not thinking clearly when thus I said. I wonder if the SC motors had forged pistons.

Looked into it and the base price is great, but once you add in all the stuff you need to actually make it work, it's no cheaper than the MegaSquirt. Maybe I can lose the obd2.....

Got a few more leads, but I think one may be scamming me...

I've asked twice where he's located and he just keeps ignoring the question. We'll see.....

Been researching my eyes out, and I'm thinking a supercharged OHV 4.0 might be a far easier way to go. Moddbox is absolutely out of the question. I'll never be able to afford that in my life.

1 question to start out:

The Lima and Cologne engines, have the same bellhousing, but, will my m5r1 actually work behind one? Were they different internally to handle the marginal torque difference?

EDIT: just realized Moddbox doesn't make kits for the OHV anyway.

Lima and cologne are not the same bellhousing. What was the transmission originally attached to?

Well they sure do look similar. Mine is from behind a 2.5.

The 3.0L Bellhousing has a wider bolt spacing at the top, and is angled. It also uses a 3-bolt starter. The 4.0L bellhousing has a narrower bolt pattern at the top, and uses a 2-bolt starter.
The 4.0L & 3.0L engines have the starter mounted on the drivers side. The 2.0L, 2.3L, and 2.5L engines have the starter mounted on the passenger side.
The Ford 2.8L, 2.9L, and 4.0L Cologne engines share the same ‘Taunus’ bellhousing bolt pattern.
The Ford 3.0L uses a different ‘Vulcan’ V6 bellhousing bolt pattern.
The Ford 2.0L, 2.3L and 2.5L Lima engines use the ‘Lima’ bellhousing bolt pattern.
The Ford 2.3L Duratec uses a ‘Duratec’ bellhousing bolt pattern.

That's from one of our Tech Articles. ^ The starter is on the opposite sides...

Ah.... yeah that's kind of important.

Got 1 good lead on a SC 3.8, but it's almost 5 hours away, and the yard it's at wants a bit too much for it. It is complete, however, with the blower, wiring harness, and accessories, minus the PS pump. I'll keep it in mind anyway.

speedometer does indeed run off the ecm. The VSS on the rear axle sends its signal to the ecm

On your Ranger, the rear axle sensor goes either to the ABS module or the GEM module, depending on whether you have 4WABS or RABS. Those wires from the rear axle sensor to the module are a twisted pair, as sine waves need to be shielded. The ABS or GEM will change that sine wave to a square wave and send it elsewhere, one of those modules is the ECM, another is the cluster.

A '90's Supercoupe is simpler in that the signal from the sensor on the trans is split 3 ways and sent to the ECM, cluster and speed control. Should be simple to convert the sine wave to a square wave for use in the Ranger's cluster, etc. Not sure if a frequency conversion is needed.

I'm trying to remember which Ford had the sine wave to square wave logic in the speed control servo.
