Spent a little bit of quality time with the engine last night.

Got the alternator on, and belt tensioned.
Got all the rest of the tin on an aligned.
Got the rest of the engine mounted sensors/senders installed.
Got the wires for the Microsquirt setup mostly installed. I mat change them around, and need to test continuity to make sure I have good grounds at the COPS and Injectors.
Got the COPS all set up on the side that did not have them.
Sourced some hardware that I has misplaced.
Sourced grommets for all the holes in the tin.

Stuff left to do:
Install Tangerine firewall back shifter kit.
Redo fuel lines in front any back.
install transmission to engine.
Put the engine back in the car.
Put the exhaust on.
Oil.
Gas.
Start the motor!
Drive it to Translog for tuning.

Actively fishing for someone to come over and work with me some weekend day in January/Feb to get it all finished up.

Good to see you are back at it Zach.

Pick a date and I will roll down. We need at least two green teeners at Hershey next year. (IMG:style_emoticons/default/biggrin.gif)

One request...I need heat! "Frozen digit" parties stopped being fun for me a few years back when the fingers on my right hand turned white for several hours. (IMG:style_emoticons/default/dry.gif)

Heat I can provide.
70K BTU heater gets it about pleasant to work so long as the temps outside are about 15 or so.

More work last night.

Was 24 degrees in my garage at 9:30PM when I started setting up. So I got the kerosene heater started and smoked a cigar while it warmed up to something tolerable.

Rolled out the components that I was going to be working on.
(IMG:http://www.914world.com/bbs2/uploads_offsite/fbcdn-sphotos-d-a.akamaihd.net-1435-1390056687.1.jpg)

The engine only needed a few things that I had run short of last time. A bolt here, nut there, that kinda thing. I never ordered the IAT I needed and intended to install on it next time, so that will have to wait.

My main task for the evening was the transmission. Wanted to get that done and join the engine and trans back together.

Transmission task was installing the rear shifter kit I got from Chris Foley last year at Hershey. I read the directions a few times while smoking the cigar, laid out my parts and set to work.

(IMG:http://www.914world.com/bbs2/uploads_offsite/scontent-b-iad.xx.fbcdn.net-1435-1390056689.2.jpg)
Now I'm committed. Also, Dr Evil is not speaking to me. (IMG:style_emoticons/default/bootyshake.gif)

Bracket installed.
(IMG:http://www.914world.com/bbs2/uploads_offsite/scontent-a-iad.xx.fbcdn.net-1435-1390056828.1.jpg)
This went really smoothly. Chris, the template you included made this SUPER simple.

(IMG:http://www.914world.com/bbs2/uploads_offsite/fbcdn-sphotos-g-a.akamaihd.net-1435-1390056690.3.jpg)
A little grease and a cone screw later, and the shifter bar was in place.
I so can't wait to drive this thing and see how much better the shifting is.

Now I hit a snag. I went to put the trans back together with the engine, and noticed that the long bolt was on the wrong side. The shorter bolt was trapped by the throttle. So I had to pull the throttle, clean and reseal to get the long bolt where it needed to be.

(IMG:http://www.914world.com/bbs2/uploads_offsite/fbcdn-sphotos-a-a.akamaihd.net-1435-1390056690.4.jpg)
Back together again! I got the nuts on, starter on and exhaust hanger turned right side up. Was just finishing buttoning it back up when the heater ran out of kerosene and died. PERFECT timing.

Went inside, got cleaned up, and was in bed by 1:30 am.

I have to put the improved shifter bushing on at the firewall, and buy/install an IAT somewhere on the plenum. After that, I think the engine is ready to go back into the car!

Things left to do:
*Firewall bushing
*Fuel tank, hoses, pump, fuel filter
*Engine install
*install exhaust, O2 sensor
*install fuel rails, injectors, fuel hose in engine compartment
*clean up wiring
*double check everything
*add oil
*add gas (pressurize system, look for leaks)
*START IT UP!

Intake air temp sensor.
Can probably get a cheap GM unit at FLAPS. Just need to do it and mount it.

You sir are a steelie-eyed missle-man for being out in a garage that cold (with or without a heater). . . (IMG:style_emoticons/default/beerchug.gif)

Great Progress!

I don't like working in the garage when it gets below 50°... Burr!

I think it's almost 80° here today. (IMG:style_emoticons/default/biggrin.gif)

If we did not go out in the cold, garage time is limited to about 6 months....

Zach - thanks for posting those shift rod install photos, that Tangerine mod is on my
list of things to buy. I already have his firewall shift rod bearing mod and it's really nice. Now you've peaked my interest again with the MS setup, I'm gonna have to
read through some threads again to see if I want to try it on my 2056 build or stick
with D Jet. Jon

Put this in the correct thread this time....

While I am using L-Jet as the base of my intake, there are bits I don't need. One piece in particular is the flapper box that attaches to the intake. I don't need it for Mircosquirt and it makes for an air restriction. So I'm going to make a connector in place of the flapper.
In this connector I'll weld in the bung for the IAT. This is an added bonus, as I did not want to ruin the powder coat on the plenum when I weld in the bung.
Flapper box:

You can see the obstruction for airflow. I'm going to make just a simple pipe instead.

At the very least I'll be taking an air restriction out of the intake path, and saving a bit of weight.

I got the stuff to make the intake pipe this morning, and it will hopefully be made (minus the bung which I could not get local) by the end of the day.

I found that an old VW Beetle flywheel gland nut works perfect as a bung for the IAT and CLT sensors. I cut off the 36mm head and used the threaded base to run the 3/8 NPT thread into. Worked perfect and you can find them in the scrap bins at a local VW shop or local VW enthusiast's house. If you wanted to, you could use a bench grinder to remove the outer threads.. Just an idea. . .

Nate, CLT should be your CHT. CLT is a measure of warmup and intake air isn't an indicator of that.

Bung and IAT already on order. I'll have the bung before I could get to someone that might have the gland nut.

I have the CLT sensor mounted to my valve cover getting oil from the head. I just used the same style cut-off gland nut for the bung that's all.

AH! The other pipe is just a hose connection (AAR?). Got it! (IMG:style_emoticons/default/thumb3d.gif)

I like the stock CHT for a CLT, but your way should work too.

Intake cut out and welded up. Turns out the slip fit section of a 2.25 inch exhaust pipe from NAPA is a PERFECT fit for the intake boot for Ljet.
Attached Image
Flange I made with the pipe fitted. I cut the pipe to length on my wood lathe, turning as slow at it would go and using a diamond shaped carbide cutter.
The hole in the flange I made with a cutoff wheel and lots of grinding to fit.
Attached Image
Just prior to welding it up.
It's all welded, except the bung. When I get the bung I'll zap that in and paint it black. This part will be done. :-)

One man's trash...

Do you know if you have a 74 or 75 AFM? If it is a 75, I might be interested in purchasing it from you. Please PM me if you want to let it go.

Thanks,
Ken
