Arrow MSD on a rebuild

This is probably a dumbass question but can putting a msd on a fresh rebuild have any negative effects? I am just kinda paranoid over my investment.

It shouldn't, but if your worried just wait until its broken in to wire it up. However it will help with starting (cold and hot) but the only hp gains are up top in the rev range atleast thats the only place i noticed any difference. it may have helped the low end but it's been so long since i've driven my coupe i dont remeber.

No, it won't. It'll provide a minor benefit in helping start when it's a bit flooded (common on rebuilds with low compression). You'll be fine.

well most people want to push higher RPMs than stock with the rotary but the problem is the ECU cannot process much higher than mid 7Ks on the S4 and spark starts the break up in that range as well. upgrading to standalone and upgrading the coils or adding on MSD boxes is what most people do to cheat the stock management systems.
