EFI mock up.

[nmk80]

I figured out what Aaron is doing, he's converting the car to EFI. He says he is still doing mock up work. What he has told me is that he wants to have EFI, AC, Power Steering, and keep it all under the stock hood.

At this moment he is getting ready to take the dash apart to figure out where he is going to run the fuel injection harness into the cab at. As far as AC goes he wants to run late model gear from the firewall forward, and the stock gear inside the cab. He says his current issues are the AC, figuring out where to run the harness into the cab, and intake clearence. He thinks new motor mounts and lack of a transmission are causing the motor to sit a little higher than normal.

He wants to keep the battery in the stock location so he plans to delete the EGR and do a little routing magic with the air intake tube to pull that off. I managed to sneak a photo under the hood when he went to get some stuff while he was laying out the harness under the hood.


He wants to get things better prepped, read cleaned and painted, before taking pictures to post but I think you guys may have some input that may help him so thanks in advance.

An EFI swap is pretty hard-core.

There are probably a dozen really nice MII/EFI swaps out there, but I don't know any of them personally. He should find a couple of cars with an EFI swap in the .ORG or .NET galleries and contact the owners. No use re-inventing the wheel...

From my point though...I wouldn't let that battery get in the way of a clean engine install. I'd get an Optima and put it in the hatch area in a pretty container and get back to the engine.

And after I mocked up the engine install, I'd pull it back out and kill that rust.

Do you know what transmission he is planning on using? I've heard of some AOD installs, but they usually had to make some "adjustments" to the trans tunnel to get them to fit.

As far as the difficulty goes he doesn't think its too hard, mostly repairing and modifying the OEM harnesses he plans to use, the car's original harness and the new engine harness.

for the transmission He's going to use an automatic, I think he plans on an upgraded factory C-something.

As for the rust he's extremely happy that its 99% surface rust everywhere he has worked on it. infact the worse case of rust he round was under the batter and he was able to cure that quickly. He had to repair one spot on the inner fender where it ate through but he already cleaned it up and repaired it.

The battery he plans to use is shorter than the one in the picture and he plans to turn it 180 degree to ensure the posts do not contact the intake tube. His secondary location for the battery , if he moves it, is to relocate it to the front left corner of the engine bay. His logic has something to do with resistance and load on the electrical system, alternator, and starter. Regardless of where the battery goes he still plans to delete the EGR.

The motor was run in his 88 brickstang that he used to dragrace however he is rather ashamed that the motor is that dirty atm.

BTW I just found his binder with the specs on the motor:
Crank: Eagle forged 4340.
Rods: Eagle Forged H-Beam
Pistons: Custom ROSS forgings 10.5:1 compression.
Heads: Trickflow twisted wedge.
Intake: was carbed, something else.
Cam: Solid lifter, I think he's changing it too.
Balance: 28oz done by Sunset Racecraft in Lubbock Texas.

aaron went to get my brother and his wife at the airport, and when they get here I will take them back to my house and probably won't be back online for a week or so.

I'm doing the EFI swap. But i'm notching the hood. prolly use a ram scoop or cowl hood to hide it. The wiring is a pain but once its going it will be well worth the trouble. If your planning on using the serpentine belt system be prepared to either move the radiator or use some pusher fans. Should be awesome. I know I can't wait to get mine going.

I know someone over at .net that has efi and it clears his stock hood I believe he's using a complete roller motor from an 86 fox.

Stock EFI intake should clear. I heard that the GT40 intakes on 5.0 explorers are shorter and perform much better than stock. On my first mock up I used a typhoon intake which is about 3 or 4 inchs taller than stock. Which doesnt even come close to fitting under the hood. So I don't think I'm going to use it.

nmk80: I know who you are, and bad girl posting a pic knowing I didn't want images put up until I could do some more work.

The clearance issue comes about because the TPS and vaccume port on the TB just barely touches the hood. This could be an engine angle problem (no transmission so I guessed the angle) or it could be caused by the previously unused motor mounts sitting a little higher, or a combination of the two. I know that this is a minor issue and I plan to run a TFS street intake which is slightly lower than the stocker. But this mockup was little more than an effort to lay out the wiring harness and adapt it to the Mustang II chassis.

The transmission will be a beefed up C4 with the MII bell. I may rollerize one of the cores I just picked up and use a C5 drum to add clutches or I might hire the work out if I can't borrow the tools to do the job myself. I'm some distance off on the transmission just yet.
