External or internal amp coil packs best?

[Chris Wilson]

Is there any preference between the external amp ignition coils and those with the amp built into each one, as far as output or reliability is concerned? At this stage of the wiring I can use either type. ECU is Motec M800, engine is RB26. Thanks.

externally placed coils will be less affected by engine heat, i have known a fair few direct fire ignition coils placed directly on top of the spark plugs to overheat and crack.

I really don't think there should be any difference, between the inbuilt ignitor coils or the external ignitor pack configuration.

Just use whichever coils are in best condition, low km's with no cracks in them (Common problem from the heat buildup under the coil covers in skylines)

The only advantage to the external ignitor pack is you could change it/swap it out for a different ignition booster more easily without changing coils as well. But changing coils is not really that time consuming.

The spark should be the same with either setup you asked about unless the coils are damaged.

can anyone get a model number for the external coils used for 26dett's? or what people prefer using i guess.
