Ignition pre amp for S2 / RS2

[B300ABT]

Anyone got a spare 1 or 2 in good working order that they would like to sell?
Cheers

AFAIK, the 351 Power Output Stage from a V6 of the same vintage will also work in place of a 351A. I know this is a cheap solution for the AANs and I assume also for the ADU and ABY. Personally, I avoided the whole thing and did the 1.8t coil pack conversion.

Thanks for that.
Seems that what I'm looking for is Ignition Control Unit 4a0905351a, which is correct for S2 and RS4.
Haven't managed to find out what the difference is between this and the part without an a at the end!

Internals are different on V6 (ABC) and S2/S4/RS4 units. Some say, that turbo units are more precise and act faster. V6 units are somewhat more sophisticated in contstruction, and this adds lattency.

Due to lack of original turbo end stages, I, and several my fellows are using V6 end stages without any undesireable side efects. At least it can be used as temporary solution. Of course I would not risk to use V6 units on some preciselly mapped 400+hp monster.
