I bought the whole diff from a nissan mechanic who had it on a G 35.
It cost me 1000.00 for the diff, with out giving him one for trade.
He told me that the parts cost are around 800 to 900 dollars/
I love the diff but there is a huge drop in gas mileage.
at least 20 %. difference at 100km is 700 rpm. 2100 vs 2800.
But the wow feel in 2nd gear is simply awsume. ( go ask the guy in the black N/A carrera that i smoked the other day ) Ya i know a bad thing to do but he asked for it.
Post is in the drag section. My girl friend has grounded me for 2 weeks for doing this.
The rev matching will drive you crazy as its a bit of a pain with these gears.
When i drag the car and shift at 7900 it only drops to 6800 in the next gear, you have to shift quickly or you hiy the lmiter. ( note it 4th gear it will not go past 7600. Its an ecu thing. But on the dyno in 5th it goes up to 8100. With all my bolts ons the car sounds increadable betwenn 7200 to 8100 rpm.
Well worth the 1000.00 dollars.
