Ok I am making a street machine and have a73 240Z with a 3 speed auto transmission. I would like to replace the 3.54 diff with either a r200 3.90 or 3.70. I am putting my car piece by piece and just got enough money to spend again... i just finished paying for new tires/wheels/struts/ and springs. Will I have to get anew drive line with that R200. I will probably put in a four or five speed trans later but I like not having to shift. What kind of RPM's am I expecting if I put in the 3.7 or 3.9 with that 3 speed?? How much quicker off the line will that exchange dmake?? what should i do to make my car quicker or faster??
