Got the Brackets back from the metal dipper/cleaner today.

Image
Image

Got the Driver's side cut off of the frame rail bit and went to fit it. There are some differences with the frame rail but nothing that will keep me from using this I think.
Image

There is a divot where the top rail of the bracket hits the rail on the parts I have - but not on my frame:

Image
Image

I think I'll keep the other side using the B4 mount and I'll just do this side welded in. Need to cut out the radiator side mount too eventually.
I believe I'll need to cut the bungs off of my driver's side frame rail where the B4 mounts bolts thread in.

I sold my Maserati this last week so some of the funds are going toward this project.

I approve this message :thumbsup: and I can't wait to see the end results!

Wow that engine bay cleaned up nicely.

Please take some vids as I'm curious what that exhaust sounds like

Many updates:

Firstly,
I got the brackets welded in and painted:
Image
Image
Image

Used the off-white, then the pearly spraypaint and the match is close enough for me!

Also, I got the 01E swap all figured out.

Started by laying out the two systems:
Image
and they are the same length overall

On the left above is 01E, B5 S4 driveshaft, and B4 AZC 4.11 rear differential.
On the right, the stock B4 V6 stuff - 01A, B4 driveshaft, stock 3.89 rear diff

The 01E is 33 1/2" long
Image
The O1A is about 32 1/2" long
Image

So the driveshaft for the 01E needs to be roughly 1" shorter.
Here are the B5 S4 shaft alongside the V6 shaft:
Image
Image
44 1/2" for hte B5 S4 and 45 1/2" for the B4 V6 shafts.

However, note that the carrier bearing is in a different place for the two driveshafts. Also, the B5 S4 bearing is made to extend about 1 1/4" further:
Image

Image
Image

The issue is that the bearing hits the mounts from the B4 here:
Image

Those of you that weld would likely just move the mounts - I however cannot so I made a bit of an extender with 1 1/4" square steel from Home depot:
Image
Image
Need to do a bit of fine tuning to get it 100% straight but seems like it should work!

Also got the fuel pump swapped out. I ordered a walbro from Marc and his dual pump bracket
Image
Image

Did the heater core job and re-foamed the flaps
The before pics are actually not that bad but - while I'm in there....
Image
Image
Image

Then I believe I have the V belt figured out now. There was a 91 CQ in a junkyard in Louisville that I was able to pull a bunch of stuff from

Now I have the following mockups:
Image
Image
Image

Also with the AC compressor attached:
Image

And now with the AC on that side, I needed to source this for the Oil return - which I have:
Image

Also I made the wiring harness:
ImageImage
Image
Image
A little more to do with it but largely done and squeezed everything through the firewall

Lastly, I test fit that Jetex Exhaust with the driveshaft in place. Seems like a great option for the cost. I'll need to connect from the downpipe to the Jetex but all in all I'm glad I found it

More Progress happening a little slowly.

The wiring is down to 1 or 2 loose wires and then going through it all to ensure I don't blow up the VEMS or anything else

A couple questions for those that have done small chassis AAN swaps:


Do I want to use hte Auxillary Coolant Pump? I think I should be able to wire it in if needed

On the PCV system:
Do I need to tap a breather or vent into my 3B valve cover?
It seems like I can use the AAN system but I'll need to run a pipe to replace the one that ran inside the AAN valve cover and would need to tap into the 3b cover at the back side

Lastly, has anyone run the EFI LS coilpack setup in a small chassis? I can't figure out anywhere the bracket will fit for me.



Some other updates:

I found a suitable crank bolt replacement on the QW forum:
Image
It's a BMW part: https://www.autohausaz.com/pn/BM-11231736585

Got the new oil pan wing installed and the turbo oil return replumbed:
Image

And lastly, a bit of clearancing to fit the turbo and downpipe. I've since also installed some adhesive heat reflective tape there.

Man I was battling the same thing with my efr it’s tight over there .

I am running those LS coils with Marc’s bracket . I couldn’t find anywhere to “hide” it but at least the bracket is nice and professional Looking . I just have it on my firewall. Was posting today in my own The was about trying to come up with an idea to cover the mess of wires I have over there haha. Maybe a battery box or alum. Shroud .
Another option if you ditch the bracket is you could mount them elsewhere and you’d have to make your own bracket in that case.

More progress today and some more problems are showing up

Got a few things from 034, their S2 coolant hose kit as well as an ABY boost hose kit. I've been trying to decide between ABY or 3B boost hoses and while I think 3B would be more correct (3b intercooler and crosspiece) but 034 put their last ABY kit on sale for half off - so I bought it.

The coolant hoses are all good - everything fits as it should. I have some of the rubber hoses but not all and they're all super old.

The boost hoses are a different story. The intercooler to charge pipe hose should work but will need to be cut since the 3b cross piece has a 90 that the ABY doesn't. But it should work just fine. The turbo to intercooler is a little more difficult. The EFR turbo is clocked super weird due to the built-in wastegate and so I will need to add a 90* elbow from the hose to the IC. should work ok too.

Also, I found a good solution for the Coil bracket. Had to remove the little shelf that held the cruise control pump under it:
Image
Image
Image

I mocked up all the cooling and fan as well:
Image
Image
Image
Image

Feels like I'm getting closer!

Now for the problems.

I had the shifter linkage all set and working before I put the engine in with clutch and flywheel. Now with everything installed, I can't put it into reverse. I have no clutch since nothing's bled but still, I am alarmed

Also, now that I have everything in, I bounced the engine a bit and I clearly need a solid motor mount for the PS to keep the turbo and such from hitting the frame rail. Are there solid B4 mounts?

anyway, happy labor day weekend!

In my 01e swapped 80 it rarely will go into reverse without the clutch. Its a notchy gear with no syncros. If it's on the ground have someone gently push the car and hold it in reverse it will probably pop right into gear. Sometimes I need to select first before reverse or even slightly let out the clutch to get things spinning so it will engage.

Edit: I was able to select reverse fairly easily on the ground before install also.

This is very good to hear - thank you!

It's on 4 jackstands so I can't try the on the ground trick. I am at the point where I can bleed the clutch though. I need to do that soon either way

I figured out what the little "divot" in the driver's side frame is for on the CQ that isn't there on the B4:
This (pictured from a CQ:
Image
side by side - the cut out frame (with the mounting parts cut out) from a CQ next to my B4 frame:
Image

It makes room for the big fan. Mine is not quite fitting:
Image

I've done some BFH clearancing there but still not totally right. I'm going to end up moving that fan about a half inch forward - which makes the shrouding not quite fit.

Exactly! Of course, you'll have to repaint that spot, but that's a small price to pay for a proper fitting fan.

I had to repaint it already due to the motor mount brackets getting welded in there. So all good!

More progress:

Here's a whole bunch pics of me working out fitment of the intake, fuel pressure regulator and breather system:

Image
Image
Image
Image
Image
Image

Also, VEMS - I'm in!
Image

Finally will be able to take the hood down from the ceiling!

With the parts I have now installed and/or have shipping to me, I should be able to fire this bitch up!
