HELP!! need CDI BOX!!
Hey guys, got a 81 911 3.0 my CDI box decided to take a poop. I need one cheap or im also looking to convert to the MSD i was wanting yalls input into converting into this or if you know someone that has one cheap
Thanks!! |
Doubt you can find a Bosch box cheap. Lorenfb fixes them. JoeBob knows other rebuild sources.
MSD will work great and is cheap. However, the labor to pull off a pro install is steep for a DIY guy. Budget a weekend for anything other than duct taping it to the inner fender. I like under the driver's seat positioned in a manner that keeps it an inch or so off the floor. |
"i need one cheap"
I never understand these comments Why not just ask for a free one ? |

send it there if it's a bosch part. reasonable $$. if it's perma-tune, round file it, can't be fixed. |
Bosch CDI........
Quote:
The cheapest Bosch CDI I've seen lately were between $250 - $300 in this forum. I doubt you could get one cheap unless the seller is giving you a failing unit. I have four (4) CDI spare units (3 in the basement and 1 installed in the engine test stand). http://forums.pelicanparts.com/uploa...1365643264.jpg These CDI are getting older and harder to find good working unit. Keep your finger crossed someone might have one laying around. Tony |
these cant be that complicated inside. what usually goes wrong in them? maybe just a $2. capacitor

Have a friend that has one for sale. He is doing a 3.6 conversion and doesn't need his.

You can also replace your CDI box with an MSD street fire. I did it on my SC, it works just fine and is cheaper with a smaller form factor than the MSD 6AL.
I think I paid $149 for mine, new. Street Fire Ignition Control - 5520 |

"THE" capacitor must be a mylar low ESR type of 1-2 microfarads not known for failure absent severe over-voltage. |
I have a 6 pin CDI from my 81 that I took off when rebuilding the engine. Yours for $200 shipping included. PM me if interested.

Your not going to beat Targa Times price Ernie 81 sc |

I strongly second contacting Bob Ashlock post 15 above. Great guy, great service. Has done 5 for me and one for a friend. Fast and very reasonable. Most important, he's honest.

not saying i dont trust him but you cant really trust anyone these days... so can anyone vouch for Targa Time having good stuff and being trustworthy?

I've come to the conclusion that some people deserve no help and are truly clueless; Warren, you would be that person. You've been provided a number of options and someone steps up to sell you what he says is a functional unit and instead of engaging with him directly you basically dis him in public...sheesh if I was him, I wouldn't sell you anything. |
I have recieved some PM's to buy the CDI. I sold it to Warren. I know it was way under priced but I felt like helping the guy out. The unit certainly wasn't doing me any good sitting on the shelf in my garage.

Sounds like this is resolved. Good that Targa Time was able to sell Warren a functional unit. Warren did contact me expressing interest in getting it repaired, but then he went dark, I assume because he was able to just buy a replacement unit.
Just to be clear about what I do with these units, I first visually inspect and test and if I determine it is non-repairable (for example, the pc-board is badly burned), or find it is already functioning properly (which occasionally happens) I will return it for no charge other than shipping. If I determine it is repairable, my typical cost is $100 - $150, depending on the problems found. In general, the components originally used by Bosch are pretty good, especially considering the era of manufature. But, often times these units get damaged by improper connections, over-voltage, etc. Varying levels of disassembly are required, depending on what component has failed. If the big energy storage capacitor is bad, I replace it with a high-quality pulse-rated polypropylene capacitor that is considerably more rugged than the original Bosch electrolytic part. These boxes come out of a manufacturing era where components were still hand-wired and soldered. Once they are together, it takes quite a bit of unsoldering of wires, etc. to get them apart for service. My guess is that back in the day, Bosch really intended them to be replaced as a unit, rather than being returned and serviced. I'm probably not charging enough to repair these things, but this is just a little side-business for me and I like to help out other Porsche enthusiasts and get the side-benefit of name-recognition for my Tach-Adapt product.

At least Bosch didn't dip them in tar like PermaDoom did....

Some of the components inside the Bosch units are NLA....or so I have been told by a good friend. Not to mention the connectors and the boxes themselves.
As such...non repairable boxes still have SOME value for otherwise NLA parts that are still good. |

Wasn't referring to Loren. I was referencing the replacement of parts when repairing the Bosch unit. I believe my statement is correct.
Considering the costs and mods needed to swap out the Bosch unit, repair is still a viable option. I have no dog in this hunt, just my experience and opinion. |
When swapping in a used Bosch CDI is it best to send it out for inspection/rebuilt or just install and send out if the 911 doesn't run right (or start at all)?

As an Electronics Tech...I have been asked many times to give a customer a break.
One time...the boat owner (I was working on his Radar) asked me how much the repair and upgrade was going to cost...and I told him about $200. He sort of freaked...and this was on a $75K boat! He wanted me to just give him the parts...so I did...and charged him $.25. Then he wanted me to show him where to put the parts...and I told him...that's what the $200 was for...knowing where to put the parts...LOL. Pay fair price...deal with fair people (like many here) and enjoy the ride. Bob |
you might find one at Parts Heaven or EASY
|
I believe Barry Hershon (IAE Inc.) makes an adapter allowing you to plug in an MSD 6AL without a lot of extra wiring. I was going to convert my car a while back (Blaster Coil also) so had him make me one when he rebuilt my dizzy.. he did a fantastic job on the dizzy.

Bosch CDI disassembly
How do I take the CDI apart to replace the transistor? I have removed all of the screws from the bottom. This is a 227.200.008 with a bad power transistor. Please reply directly wa3vez@comcast.net. Thanks.
