How fast can you drop an engine (CIS)?
 

Obviously makes a difference how many you've done. Please comment on that as well.

I'm trying to decide if I should go with a race engine (for the track obviously) and a "street" engine, and if a great deal of time would simply get tied up making the changes. Why? Because I might be headed back to Kali....

Or should I just sink my money into a early 70's tub and be rid of the 930? Suggestions welcome.

Peter,

After you have done a few, its easy to get one out in an hour or so, especially if there are two of you. Access to an air compressor and some air tools make it a breeze, a lift is even better.

Head underneath to get the CV bolts, clutch linkage, throttle cable, speedo wire or cable, heater hoses if installed, ground strap and starter cable and slightly loosen the gearbox bolts. Oil should have been drained and pull the "S" hose. Inside to do the gear shifter link.

Top is the fuel line and 14 pin cable as well as the coil wire. Then the two rear mount bolts. Put a jack under it and remove the four mount bolts and its done.

What did I forget? :)

My first engine drop took about five hours.
The second drop was about two.

Remembered another thing...

Disconnect the back up light wires off of the gearbox.

Out in 1.5 hours and back in and running in around 2.5 hours.

That's after doing 1 or two.....

about an hour - Joe don't see you mention shift linkage

Somewhat off topic, but I remember reading about a contest years ago where the contestants (2 people per vehicle) had to drive a Volkswagen Beetle 100 ft, drop the engine, re-install the engine and drive an additional 100 ft. Fastest team won.

I think the winners did it in less than 8 minutes.

2 hours out, 2-4 back in w/o help. faster with help.

8 minutes, mike?? holy cow..

Thanks but got that one. Have to be missing something else?

Inside to do the gear shifter link.

Wow. I remember pulling the engine was pretty easy - without a jack (just me bench pressing), but 8 minutes?

I guess I was worried about extra plumbing with the CIS and the smog pump et al. making it a prolonged effort no matter how experienced one was.

I amazed myself by dropping my engine in a little over 1hr by myself!

We once timed ourselves. Three guys. Back the car into the garage... start timer...

Crankshaft in our hands... stop timer... 4 hours.

Going back together takes significantly more time. :-)

Is it because you're familiar with the procedure? Or something else?

There's a group of us here in NoVa/DC/MD. We can do them in less than 2 hours. Things t hat alway seem to be a holdup: getting the transmission nose out of the tunnel and jacking it up just high enough.

It does take longer to go back in... the accelerator linkage was a hold up the last time I did it. It's hard to get the clip on when you can't reach it. The rest just bolted right up.

Ask me how long it takes to get out a 944 motor. :rolleyes:


For your purposes, I'd just buy another car. It's a pain to just put the track tires on for me. :D

That's what I'm thinking, but that means space and $$$$$

The thing that takes the longest (for me) is jacking the car up high enough to get the engine to clear.
If I had a lift I could have the engine out in 20 minutes and back in and running in 35.

Disclaimer:
I've done it a couple of times and used to make a living repairing large industrial machinery for a living, speed (and accuracy) meant profits so I have experience with this sort of stuff.

I have a friend who used to build modified 911 turbo motors down in Florida. I've pulled a 3.2 Carrera motor with him in just over an hour. His best time? He tells me that with a team of guys familiar with the procedure, lift, air tools, - 17 minutes.

I think those very short times quoted mean a couple of things:

- A well running, clean machine, meaning the engine comes in and out regularly. Not the first time since it left the factory.
- All tools on hand and no fumbling for the extension sets or the proper size wrench.
- A ready supply of consumables (CV bolts, gaskets) and spares for stuff that gets dropped and rolls away.
