Removing an M20?

[Leeroy]

ill actually be putting a M20 in today or tomm. Depending on whether or not i can find a truck.
This sounds lame. But swapping engine(m20) is like riding a bike. once you learn its easy as pie.
You create a checklist in your brain after a few swaps....guibo,shifter,motormounts,wiring,exhaust, radiator,etc.........

That's what I've heard. I want to learn first cause I have never done an engine swap. There's to many things for me to over look/forget. I don't want it to get messed up, I just want my perfect running alpine motor back. :) Hopefully. everything will go smooth. I will learn what I need to do for next time, so that I won't be needing any help. Thanks for help everyone.

don't forget the ground strap to the oil pan/block on the underside of the engine. that's an easy one to miss and you'll be scratching your head when you start lifting the engine with a cherry picker and the whole body starts to lift off the ground..

why is everyone saying to remove the dme harness from the glovebox? I pulled mine without doing that, just unplugged everything and left the harness in the car.

I don't know, 2 connections vs 20. Fishing the injector harness through the manifold is a pita with the engine in the car.

if there is a swap or rebuild to be done all those 20 connections need to be removed anyway, so your just adding 2 more for no reason?

You can argue all you want, but the fact is that the car was designed to be swapped with the DME harness on the motor.

Try it, you will like it.

I not really up for arguing but, the two "extra" connections will save you about an hour of frustration.

[nando]

do you guys really have that much trouble with M20 wiring?

if I'm not forgetting something, there's 11 connections. temp sensor, temp sender, ICV, impulse sensor, coil negative, VR sensor, purge canister, AFM, oil pressure switch, TPS, and O2. easy as pie! the only ones that are required to run the car are the VR, temp sensor, coil negative and AFM (it will even run without the AFM, just very poorly).

Uh, aren't the alt leads and starter leads part of the harness? Also 6 injectors need to be hooked up. That's 10 more. I'm not saying it can't be done or that there are too many connections for my brain to handle, it's just easier to work around the engine and see all the connections with it on a stand. I think pulling the plug through the firewall and unscrewing the harness plug is a small price to pay for simplicity.

Just expressing ideas and tips from experience. You guys do what you want.

no they are not part of the engine harness. also, you can unplug the round connector under the intake manifold (that also connects to the ICV, TPS, and coolant sensors), so it's actually less. I wouldn't really count all 6 injectors as seperate connections either, especially since there are technically only 2 banks of injectors anyway.

this thread should be stickied.

Swap is mostly done :)

Both motors out. Good motor in the bronzit!

WooT

Good work Blake!

Are you kidding me? I believe there are many things I can learn from you but if I want to leave the harness in the car, do I or do I not have to unplug all six injectors? the other wires as well? I think you're just trying to be facetious now.

[nando]

no, you don't have to - unplug the round connector under the manifold. not only that, but unplugging the injectors is incredibly easy, especially on the later harnesses. stick a screwdriver under harness cover, and pry up. it just pops off.

I swapped motor and I did it by pulling DME through the firewall. Easy as pie. But the real problem is....that its an electrical problem and it does the same thing to this motor.....

SUCKS...

Get that Bentley tomorrow and start reading.
