G.E. Coil Pack Conversion

Recommended Posts

EMU or other piggybacks with NA ECU works fine up to a point where closing the plug gap (reducing the efficiency of the spark) will no longer prevent boost blowing out the spark.

 

The more efficient TT coil-packs ignition system cures this and it's such a cheap, simple and better way of doing it in the first place, why not?

 

Why do you think Mr T. put coil-packs on turbo'd J's and later upgraded the GE in VVTI form with coil-packs?

 

The 3 coil VVTI system is more efficient than the earlier 6 coil system, which also conveniently fit nicely under the N/A induction and can be used with TT ECU.

 

No distributor to get in the way of the turbo plumbing and it looks cool too.

 

 

Ignition upgrade = Win

 

Can run more boost =Win

 

Space for turbo & induction = Win

 

Easily sourced OE components = Win

 

Cheap used components = Win

 

Easy to do = Win

 

Mostly plug & play = Win

 

Looks cool = Win

Steve,

 

Not sure re. the Emanage blue & N/A ECU, yet if not, use a T.T. ECU with the Emanage and Bobs your Uncle. :)

 

Join the coil-pack group and ask your questions there, then the answers are easier for others to find.
