Does the 91 motor(small journal main) have a external balancer? Crank has something on the end of it on outside of the timing sprocket

Hello I’m new to compacts but wanna build a 2.3,does anyone have any updated info on building these before I read 70 pages from 10 years ago? I currently have a 83 2.3 with a lil rod knock and a good 90 2.3 and was planning on shaving 20 thousandths off the 4 plug head and putting it on the newer bottom end with arp studs, the 83 distributor and a msd box. Also thinking about using the newer cam and rockers or should I just get a aftermarket cam? I also have a 3 speed with linkage is that the right 3 speed? What bell housing is easiest to use?

Running a 2002 Mustang. Is the 3.8 transmission bellhousing the same as a 2.3?

I’ve been out of the 2.3 world for a couple years, but I just came across a 1988 foxbody with a 2.3 4 plug head efi with TFI and a t-5 5 speed that a friend I work with bought for a drag car and had no desire for the drivetrain and ran and drove! I pulled the motor and trans and kept the harness all in tact. The only wires I didn’t keep were on a quick connect. 2 connectors (1 black and 1 gray) went too the interior of the car and one that was on the inner drivers fender which went too the headlights. I will try to get some pictures uploaded sometime, but basically you take 2 wires which go to your starter solenoid (if you plan to not use the factory solenoid) and you splice 1 wire and power it too a 12v source along with the 2 fusable link wires that go to the starter solenoid too power the pcm and make it work. I did this with these 3 wires, ran a wire straight from the starter and touched it too the hot side of the battery (pulled from the vehicle) to power it, and dumped some fuel in the intake since I cut the fuel lines. The motor fired right up and seems to run well! I’m more of a carb and duraspark guy myself with a mechanical fuel pump but I just wanted to see if it could be done. I will try to get pictures uploaded so someone who wants to run a stand-alone harness with EFI has the option!

Thanks to a wecrash member on Facebook, there is a ground wire that needs to be hooked up to ground the pcm and control the ground on the injectors. I will update with what pin it is on the computer. Sorry for the inconvenience, never crossed my mind with having the fuel lines cut

Thanks C4 postimg.cc/tY4bFpDpostimg.cc/ygK4xHk1postimg.cc/cgcq8bnQTop pic should be an engine wiring diagram for an 88-90 2.3 mustang. 2nd pic is of the gray connector that you splice the top left wire to 12v which powers your EEC. Last pic shows the 2 fusable links that were hooked too the starter solenoid. They both are wired into the upper left EEC wire and powered too 12v. I’m pretty sure #60, #40, and #20 pins of the EEC needs to be grounded. It grounds the EEC which controls your ground on the fuel injectors and everything else that needs it. I hope this helps *Update* This should be all you need If you keep the factory harness in tact. Pin #1- 12v power supply. Pin #20,#40,#60 ground. Pin#1 powers everything that needs power through the EEC. The only other thing needed is a fuel pump, simple as grounding and a hot wire or your power supply choice. Mine runs just as it did in the car like this. Sorry for the long post and confusion. This should work for an 87-90 mustang 2.3 TFI

Anyone know how the starter solenoid hooks up. mine was unplugged and wires were missing when I got the car and I can't seem to find any wiring diagrams on how it hooks up. thanks

From the 2.3 wiring thread. Other side of the push button goes back to battery hot. This can be the sticky for this topic. I'm sure it will fill up fast enough. Here's one of the Dura Spark pics I saved.

Here's one of the Dura Spark pics I saved. Ok so the one I have has 4 screw posts on it, 2 bigger ones (one on each side) and 2 smaller ones out the front. Is it still routed the same way . Each of the smaller ones has a letter, the left has an I and the right has an S. am I right to assume I means ignition? I'll try to get a pic of it. Just so I know, what is Dura spark? thanks.

You won't damage anything if you get it wrong...it simply won't work if you get the wrong one. Bear in mind, the mounting bracket on those IS the ground for it. If the mount isn't grounded, it won't work.
