Can you elaborate a bit more on the 3.46 vs 3.08 on a 6MT?

Pros and cons of each?

A rear differential ratio is how many turns of the input shaft(Transmission output) to turns of the wheels. A 3.46:1 will give you more wheel torque but sacrifice top speed then a 3.08:1. I would have to look up the transmission ratios for a 6MT to find out what kind of difference it would make numbers wise. There are online calculators that you can plug the ratio numbers into to give you the top speed in final gear etc.

2) Install Cobb/piggyback? and JRZ suspension. 3) Build parrallel HPFP and highflow intake manifold with multi-port fuel and meth. 4) Build full cage and staged twin setup with turbochargers. HTA3076R (tial.82 or Garret divided 1.01)/ HTA4205R (tial 1.16)

No I get that part, but I was referring to actual real world application feedback. Perhaps from people that have it. Or any info on how much top speed suffers. Just looking for some help in decision making between one or the other.

In 2006 I bought a new Honda Civic Si for $22k. That car included an LSD.
