993 coil packs for the 964

[patz]

Looking for some BTDT replacement information on coils. I hear that the 964 replacement coils made in Brazil have a high failure rate.

Has anyone used the 993 coil pack and what needs to be done on the coil wires? Cost? Time and effort?

Hello,

not sure if you can use 993 coils on a 964 coiled engine...

have a used 964 dual coil if you are interested.. $100.00

might be at the pelican parts meet in Jan .. 2016 at PV.

i am located in LA.

Good Luck,
Harry

The coil part number is 0.221.118.322 and it's same coil used in the 84-89 Carrera as well as some 944 cars. You can get these used on ebay all the time, I'd prefer an old used one to the new Brazil silver coils.

Not all black coils are from Germany, I've seen these black coils made in Germany early on then later made in Spain, the ones from Spain seem to be in a few 964 cars I've worked on. I have a twin plug I'm working on at the moment and the coils are from Spain.

The 993 coils are very different, I'm sure they do not have the same specs such as optimal dwell charge time.

Becoming every more common given the issue with the brazilian silver coils. Search the 964 forum at rlist.

also the 964 coil wire will not fit exactly on the 993 coils.

you would need the 993 coil wires and re-locate the 993 coils to the
engine crossbar.

993 coil wires are short ..compared to the 964 coil wires

cheers,

All you need to do is get the coil connectors for the 993 and put them on your 964 leads. Connectors are p/n 928 602 557 00 (or beru 0 300 513 124 / 1 kOhm) I did this mod in August and it required no modification to the car, a simple hole drilled into the 993 coil bracket, a piece of 6mm threaded stock which goes into the original lower coil mount, the 996 pack slips onto that and then the ignitors, a nut holds it all in. I got a little fancy and used a spacer to offset the coils from the sheet metal and a bushing to keep stress off the ignitors when tightened down.
Cost? about $125 for coil pack, $25 for coil covers and connectors, a few bucks for 6mm threaded stock and misc hardware. Less than an hour and my car has not run this good in ages. Had nothing but failures and a hefty tow bill with the Silver coils, car ran better with the 24 year old coils than it did with any of the Silver coils I tried and this is one of the best mods I have done performance wise

Pics of install, I used 6mm threaded stock with spacer and nut to hold the ignitor pack in original vertical position, no modification to car required. A hole drilled in 993 coil bracket is all it needed (for threaded stock to go through) \
