Not out to steal anyone's thunder, just want to have all the info in one place so that the next person can read this and know everything they need to do this swap.
People I need to thank who provided most of the info I needed to do this swap:
Chris Scarpulla, Greg Perry, Andreas Miko, Rex, mpg9999, the illest rice, jerryeads and I'm sure, other people who I'm forgetting.
Here’s the details on how I swapped a VE into my ’93:
DE Removal
Depressurize fuel line
Remove hood
Disconnect and remove battery
Remove strut tower brace
Disconnect thermostat ground from chassis
Disconnect MAFS harness
Remove MAFS
Disconnect vacuum hose from intake piping
Remove intake piping
Disconnect clutch cable

Remove injector harness
Disconnect PAIRC solenoid valve
Disconnect harness grounds on intake manifold
Disconnect harnesses
Disconnect radiator fans
Drain radiator
Disconnect coolant overflow hose and remove tank
Remove radiator hoses and high side neck
Remove radiator and fans
Disconnect passenger’s side harness ground
Disconnect the 4 engine harness connectors from their chassis connectors
Jack up front end
Separate primary from secondary exhaust header
Remove front wheels
Remove driveshaft nuts
Drain transmission gear oil
Remove drive shafts
Remove power steering pump
Disconnect A/C compressor harness
Remove A/C compressor
Disconnect and remove alternator (may or may not be necessary)
Disconnect tranny ground
Disconnect shift linkage
Disconnect heater hoses
Secure engine with hoist
Disconnect transmission mount
Disconnect engine mounts
Remove engine
VE prep for install:
Clean engine bay
Clean transmission
Flush coolant overflow bottle
Flush radiator
Flush heater core
Flush engine
Remove lower heater hose from firewall.
Connect the DE EGR solenoids back into the harness with no lines connected to them.
Wire in VE IACV-FICD connector on DE engine harness or swap DE FICD to VE IAA unit.
Unwrap harness to get more length out of FICD and AAC wires.
You may need to extend your TPS wires, I wish I had.
Extend E.F.I. harness grounds (intake manifold grounds) or run a jumper wire from the intake manifold to the grounds.
Swap passenger’s side engine mount bracket to VE
Swap front engine mount bracket to VE
Swap DE engine harness to VE
Swap DE A/C compressor bracket to VE
Swap engine temp sensors to new engine
Wire in MSD window switch
Run wire for VVL solenoids
Modify DE distributor by removing lower tab and swap to VE
Swap Ignitor chip and bracket to VE (cut tab off bracket)
Fabricate bracket for DE coil to mount on VE or use one bolt hole on coil to mount.
Swap exhaust header to new engine
Swap DE flywheel and clutch to VE
Install tranny on VE
Regrease starter and install in VE
Swap clutch inspection plate to VE
Swap front throttle cable bracket to VE
Swap wire harness brackets to VE
Widen slot on PS pump bracket to allow movement of PS hard line to clear oil filter.
Install engine
Things to do after engine is in:
Connect hose from the large nipple on the charcoal canister to the small nipple on the VE intake manifold. You’ll need to buy or make an adapter since the canister nipple is ¼” and the intake manifold nipple is 1/8”.
Connect the small hose on the charcoal canister to the small nipple on the intake pipe between the MAF and the TB. Both are 1/8”.
Connect the brake booster hose to the large nipple on the VE intake manifold.
Connect lower heater core hose to coolant nipple just above filter on VE.
DE TPS connector will plug into the top connector of the VE TPS.
Highport intake piping is a bitch to make work with the VE. So either have materials on hand to make new piping, or have a lowport CAI on hand.
Remove topside driver’s side engine to intake manifold bracket. Move throttle cable bracket to that location or fab new bracket.
Wire in MSD 8969 to control VVL solenoids. (Tap green/yellow wire at the ignitor chip for the MSD white wire. Connect solenoid grounds to MSD yellow wire. Ground black wire. Red to keyed on circuit. Gray wire not used.
Some tips:
Heater core and VE heater hose connections are all 3/4". DE has 5/8". So you'll need a 3/4" to 5/8" adapter for the one OEM hose you're reusing to connect near the TB. For the shorter hose just get yourself a new piece of 3/4" heater hose because the OEM hose won't stretch to fit. Also get yourself some new hose clamps because the OEM ones suck, especially when they're old and corroded.
Thread lock or glue the screws that hold the throttle butterfly on the shaft. People have had their engines ruined from those backing out and getting sucked in.
Wire cross reference for DE to VE MAF:
DE--- VE
OR/L = W/R
W = W
OR = OR
First wire is power from the ECCS relay, second is ground through the ECU, third is the voltage output read by the ECU.

I got a few questions about this... I'd appreciate it if you could answer to the best of your ability. I will be doing a swap within the next couple weeks.

So I just need to have them plugged in, but doing nothing. Example I can just tape them up and call it a day.

I don't understand what this accomplishes... Why would you wire a VE connector if you're using a DE IAA unit?

Charcoal canister?

Same as above.

Oil filter I assume?

So the highport accordian goodness won't work with the lowport?

lol, the more detail people give the more questions we have.
Gotta get your d*ck wet taiden, just start it up and youll soon answer all your own questions
Good job on the very assertive list of what to do rob

Maybe the low port is different, but my heater hoses were the same size as the VE. I reused one, and made the other since it connected to the other side of the engine.

PAIRC is the valve on the exhaust manifold. Let's fresh air into the exhaust.

Yes

I'm not sure about B13s, but B14s need the solenoid hookec up, but rerouted to not cause a CEL

If you are use the DE part, you don't need to rewire anything. The VE part fits better, and the idle screw points the correct way. I had a picture in my gallery, but it's gone.
Quote:

Yes, you re use all your DE mounts.
Quote:

No, that is the part on the back right corner on the valve cover
Quote:

Same as above.
The charcoal canister does nothing for performance, why not leave it conected?

Yes

Might not be needed. See my other post.
The VE install is not that hard. Other than a few things, it's the same as putting a DE in.

Alright, thanks a bunch man. I've started pulling things apart, and I'm learning a lot, but having an idea of what I'm going to see helps a bunch.

I don't understand what this accomplishes... Why would you wire a VE connector if you're using a DE IAA unit?
You can't use the DE IAA unit on the VE, they're entirely different. The VE one has a hard pipe that connects to a hose which connects back to the TB to MAF pipe. On the DE the air rerouting is done some other way, as it does not have that hard pipe nipple on it. But that's all a mute point because I wasn't saying to swap the whole IAA unit, just the FICD itself or cut the DE FICD connector off and solder on the VE FICD connector like I did. You can swap the DE FICD over to the VE IAA unit. I chose not to because my DE IAA unit is brand new and cost me a lot of money, so I wasn't going to render it useless by taking the FICD off.

My VE didn't have any of the VE mount brackets on it, so it was easy to just bolt my DE ones onto the block.
Quote:

I made it work on mine but just temporarily until I make my own CAI. Some VE's come with the VE MAF to TB piping, so you if your's comes with that then you're in good shape.
Quote:

You could try but it's a lot easier to just go to the auto parts store and buy a piece of 3/4" heater hose and a 3/4" to 5/8" heater hose adapter. You'll probably spend more for the wrong parts if you try to get them at home depot.
just a few small questions. What was the need for the VE maf?
Are you useing your oem ecu are modified jwt for the maf? Or cn you just wire the maf in and expect it to work correctly?
thanks for any info on this
