Finally started to Rebuild the 2.4

[bavaria911]

Almost done...5 Jan 2011 new Pics:

Figured I would start a rebuild thread of my 40 yr old while at ATSpeed racing and listen to the masters (meister) if you wish to add or ask a question to my logic.
I currently have a 1970 911T with a 1973, 2.4E (had Webers -- sold to return to MFI). As we tore down the motor, I found she had 2.2S P&C’s and stock S cams. This made it easy for me to pick which of my two MFI systems to use (the 013 (S) or 015 (T)) ... I picked the fresh 013 rebuild from Koller /Schwimmer of Bosch, Nuremburg Germany. I will be selling the 015 system, once I get her running.
We sent the case out to Ollie’s for the standard updates -- oil by-pass and truing of the case. Cams where sent to John Doughterty (Camgrinder). Heads sent to Anchor Atlantic Group an East Coast company in NJ -- that stamps your name and the company/date when completed.

What I am working to buy or need additional advice:
- My heat exchangers look worn – do I repair and Hot Jet or buy a good used set here from a Pelican? $$$ is tight.
- I have a 003 Bosch Distributor (2.4T w/ a 73 rev limiter); must I change the advance curve?
- My starter is old but worked, should I buy a light weight or a rebuild Bosch for a trade-in?
- Alternator has the half moon red part on the back – before I pulled the motor, when she sat at idle the gauge would glow red…once I increased the RPM the light would go out. What is the normal issue here?

Here are a few pictures for now :

Cooling project:

A glowing alternator light is usually a bad diode in the voltage regulator. The regulator clips off the ac sine wave and makes a pulsing dc current. The more diodes, the more pulses, the smoother the dc current. If one or more diodes goes bad, the dc signal gets more intermittent. The alternator light responds to each period of low voltage by lighting up. The glow comes from the fact that incandecent lamps take some time to heat up and produce light. As soon as the lamp starts to glow, the voltage is good again and the lamp shuts off. This repeats at the frequency of the sc pulses. As the revs rise, the good voltage pulses get closer together and so the lamp is off more than it is on and the glow fades. At low rpm, it will just have a faint glow, however.

Looks like a fun project Scott. Did you find a set of heat exchangers yet?

Here are a few pic's when we tore down the motor and tranny:

More older pic's during tear down phase:

Notice the cracked cylinder -- Tom Butler helped me with a replacement !

I found some Heat Exchangers for a fair price. Here are some Pic's before going to the clean-up phase:




My HE's (the older set are for sale $200 shipped anywhere in US)

Vr,

Here are the HE's after a good cleaning - four (4) areas needing welding, and a good coat of alloy heat paint. Total cost invested is around $270... not bad.
My old ones are for sale. See pics well above this group.

Nice. Can't wait to get mine done. All the machine work is done as well and just need the time to get it all together. We are close maybe we can get together some time in Spring and chat....I am sure yours will be running much sooner than mine

PM sent. There are a few great Pelicans living very close to Ft Meade and B-More.

Vr,

Slowly the case is coming together:

Here are four pic's of the engine with the 013 MFI system mounted.

Wow, I just pulled my motor (1973.5 911t targa w/CIS) yesterday and will start to take it apart today. Hope it goes as well as yours. I'll keep you posted

Cheers, Gibran

Scott, your engine is looking great. Beautiful job with lots of attention to detail.

[bavaria911]

Just back from the shop, the motor looks great. We should have the motor done in 10 days and next is the 915 trans:

Mark -- Thanks for the kind words...The MFI really looks great doesn't it !
