TWM & GMECM

[jtyler]

It is a Nissan U20 engine if that tells you anything.  There is a Pertronics and Crane/Allison kit available if that helps.  How many
triggers/crossings do the GM distributor type systems usually use?
(I'll look into it myself)  


Yes, the TWM's have TPS's (various types available),so that part is easy.
