Engine management

[TimT]

As I am tidying up the loose ends for my GT-5 car. I am left with a dilema. I sold my '67S distributor, and Crane ignition box, which leaves me sparkless. I have elected to not get electromotive coil packs. I have purchased a stand alone engine mangement system(in the future I will explore the limits of the 2.2 engine with modern controls)

I need coils.

Is anyone aware of coils with integral ignitors that have two outputs?

Most two output coils you see require an outside ignitor.

I understand that the coils from a Subaru Outback have integral ignitors.

I can get two three channel ignitors, and fire 6 dual output coils.

but the installation will be much more streamlined with 6 coils with included ignitors..

WOW I fell off already?

last time I looked 71 ppl checked this thread....

and its a new forum!!

Tim,

How will you even trigger the coils without a pickup?

I think we need more info here - you haven't even confirmed that you're twin-plugging it...

OK i guess some background info is in order.

The engine:

2.2 high compression
twin plug heads
web cam 158r cams dialed in to peak at 7200rpm
heads opened to 38&36 mm
930 oil pump
and all the expected race preparations

Fuel delivery:

Weber 40 IDA with 34mm chokes and jetted to perfection

Ignition:

none ( sold my '67 S dist and crane box custom wire etc.)

I purchased a Link2 engine management system, the unit has 8 injector drivers, and 8 ignition drivers. This means on a 6 cylinder Porsche engine, you can have fully sequential injection and waste spark or sequential ignition.

You may wonder why I bought engine management for a carbureted 2.2? Because this time next year I plan on installing throttle bodies, and fuel injection. Then I will see how much power i can get out of this engine before i make it a hand grenade.

The most aftermarket ems require an ignition module or ignitor that switches the coil. Many cars have an ecu ,an igniton module, then coils. I've been told that there are coils available (twin tower) that have integral ignitors.

I want to neaten up the wiring loom I am going to have to build, therefore the coils with integral ignitors would be cool.

Im going to trigger the EMS with a motronic wheel on the crank pulley ( clewett)

Tim,

Talk to Derek at Huntley racing. They have designed a full twin-plug system that I believe uses the Link system and then drives a set of dual coils that are market available... He can probably tell you which coils and I know even has them in stock pretty cheap...

[Wayne 962]

Rick Clewett is an expert on this - he can guide you in the right direction...

DUH... Thanks Wayne... I even read that he bought/is buying the pickup wheel from Clewett, don't know why that didn't occur to me to ask him...

[TimT]

I have helped install an electromotive tec-2 from clewett, and spoken to Rich on the phone many times. At some point you wear out your welcome, I dont want to get there with clewett.

A very good friend of mine has a shop, and allows me access to worldpac ( an east coast import supplier) and porsche directly so I can get many parts at jobber cost. I built and maintain a website for him and hence he lets me get parts at his cost.

I have found bosch coils with integral ignitors, but they are single output. I would need 12 coils to fire my engine......

Maybe Ill have to just have to use the ignition modules. I found coils from MSD at $40 per but i need two ignitors to fire them and I need 6 of these coils to fire my engine

You might be able to use a coil on plug solution, which sometimes have the igniter on-board. The GM used on LT1 V8s, I believe, have igniter built-into the coil, and these have a short spark plug wire. If your coil is near the exhaust, the short wires will help to keep the heat way. Another source are coils from late model motorcycles.

Any way you go, it won't be cheap, but if you have a twin-plug engine, you probably aren't a pauper.
