Car prepping - engine/transmission removal

Engine/auto transmission removal:
After living in harmony for 34 years it's time for the car and engine+tranny to say goodbye to each other. Yes, I spent some good money and a countless amount of labor to bring the stock engine up to close to perfect condition a few years ago. Everything that was not in tip-top shape was fixed, replaced, upgraded or improved. Well, one might say it was all for nothing but, hey, I achieved my goal and was very pleased with the results. I am not planning on ever selling the engine or auto transmission and even though it is very unlikely to ever be reinstalled in 1283 again, there is a certain value to keeping the matching numbers together.

Car prepping - upgraded radiator

Upgraded radiator install:
The high performance, aluminum radiator went in with some trouble but once it was in, it fit like a glove. The only thing I regretted was that I did not remove the A/C condenser. Yes, the "norm" is to leave the condenser in place while doing this but then you're also guaranteed to bash in the highly sensitive alumunim radiator fins in the process. The new motor comes with an entirely different compressor, so since Ed is going to crack the A/C system open anyway, I should have just done this with the condenser removed. Oh well, the damage was minimal.

All done. Very nice fit once I got it all in place.

A last couple of outings

Ed is a little backed up with on-going projects so the plan is to have the car ready to ship end of April, so I took the car to a couple of events before the stock motor is retired:

North Texas Irish Festival:
To me, me and my friends in the little Dallas group, our annual outings at the North Texas Irish Festival in early March is typicallly the highlight of the year as far as Delorean get-togethers and we get pretty good promotion - even a dedicated webpage. The Irish like so many others, love the Deloreans; most aren't even aware why we're there, until they learn that they were built in Belfast, Northern Ireland! People are incredibly friendly but where there's liquor there's trouble so you have to be on the look-out for beer spills as they lean into the cars. Very common.

Cars & Coffee:


#1283 on C&C's website!

Packed, as always, but what a great venue! Car enthusiasts are everywhere and this is where they come together, once a month under no pretenses. This time I was thinking to get a good parking spot so I got there at 6:30 - I still had a hard time finding a place to park!


Here I have stepped away to get a break from all of the questions

It always strikes me how much people "know" about the history of the Delorean.But, no doubt, this marque has a special place in peoples hearts (very much, of course, due to the Back To The Future craze); everyone just love to look at and talk about Deloreans.

Once I got home and parked in the garage, the stock engine - #1163 - was shut off for the last time. The prep process to convert to stick shift started immediately thereafter.

Shifter adapter, upgraded radiator

Adapter plate:
I have learned that the mounting hole pattern and x-y-z location of the auto shifter is entirely different than that of the manual shifter. Also, some sheet metal cutting in the cavity where the shifter goes will be needed as well.

Turns out Martin Gutkowski in the UK offers a very good looking aluminum adapter plate that locates the shifter to the correct position and height, so I purchased a CAD copy of his design:

The 12 stand-offs are meant to be cut in the same swoop as the plate and stacked three high in each corner in order to raise it 3 x 10 mm = 30 mm. The concept of stacking multiple stand-offs seemed a littly wiggly to me so I opted for purchasing them separately as one-piece 30 mm pieces from McMaster Carr instead. I e-mailed the file to Ed's machinist in Florida and here is how it turned out:

Very nice!

 

Now, this does not alleviate the need to cut into the frame but I'll deal with that later when it's time to install it.

 

Upgraded radiator:
The high output engine is going to require more heat rejection, especially here in Texas. I have looked around for a high performance radiator and the best alternative seems to be the radiator offered by Ed Uding at DMC Europe. This aluminum radiator can be found here and was highly recommend to me by another Delorean that had swapped in an LS1 engine.

Bye bye manual transmission

All of the manual transmission equipment has now been cleaned, repaired, straightened, cleaned, painted or plated and is looking and working great, so it's time to ship all of it to SEO Motorsports:



All of it
(the clutch will only be used for fitment purposes)

It's a wrap...!
 

... and it's outta here!

Ed is pretty backed up with a couple of Delorean projects ahead of me so it will probably sit in the corner of his facility for a while. From my point of view though, this represents an important milestone that will allow me to focus more on the getting my car ready.  

Parts prepping

Transmission:
First off I sandblasted the transmission with walnut shells just to get the grime and muck off of it. It turned out pretty good:

Ed recommended that I don't paint or powder coat it to keep heat transfer at its maximum.

Output nuts re-torque:
A common issue on the manual transmission is either of the two output nuts backing off and grenading. So to make sure I'm covered I removed the transmission's rear cover and retorqued both of them (using a very nice loaner torque wrench from O'Riley's Auto) to spec and staked the nuts into place. I also applied transmission grade Loctite:

Heavy duty shaft coupler:
Later on, SEO will split the gearbox open and add a heavy duty shaft coupler and roll pin for all that torque:

Luckily, Ed will not need to undo the output nuts I have just secured.

Pedal box assembly:
Next I tackled the pedal box assembly: After straightening it, sanding/painting, lubing it and installing all new miscellaneous hardware and springs, it looked and worked like brand new.

The springs were a challenge to get in place given that the pedals are pre-tensioned. (Come to think of it, replacing pedal springs must be impossible with the pedal box installed in the car, so if you have it out I would recommend to anyone that they also replace the springs to avoid a mess later. (Removing the pedal box is not a small job, btw!))

Parts plating:
Apart from degreasing and painting everything, a large part of the components were shipped to Dave and Julee at Delorean MidWest (DMCMW) for plating. A few years back I had also "fake"-painted some components to look like they were plated but over time it started looking tacky. I pulled those parts off of the stock motor and added them to the batch thinking that someday, somehow someone might appreciate that:

just LOOK at that....

DMCMW is well known in the D community for being fast, customer oriented, friendly whie providing good pricing and top quality and this time was no different.



A closer look

Here is how everything looked before it was shipped to me (gulp)...:

... but a closer inspection told me that everything that really matters was actually in very good condition (sigh of relief).

Here is a picture of a bent crossgate bracket. Not good, but readily available from DMCH:

 

The pedal box needs some work: Links, clips and rubbers are missing. Some of the springs are broken but between the seller, DMC and McMaster Carr there shouldn't be a problem rebuilding it:
