If you need the installation parts separately, we can supply those as well. At a minimum, you need the Install Kit #1 to put either of these into your car If your car has very low miles (under 25k or so), you can probably get away with just the Install Kit #1. If your car has more miles, or you don't want to rely on your installer having to reuse parts Nissan says are use-once (such as ring gear bolts, bearing seals, etc) we would highly recommend you also purchase Install Kit #2. Install kit 2 has has all the bearings/seals, and new ring gear bolts as well, and combined with Kit 1, will give you all brand new hardware, etc for the full pumpkin - it's the best way to go and covers all bases. Each of the install kits is sold separately.

Got a tech question about the gears, please refer to this stickied thread:

Hi Adam,

How big is the job to install. Have you done the conversion on your car - I know you are big on your performance gains in a NA car!? Price and shipping to UK?

G

get1 - it's about a 4 hour job to do but requires specialized tools to set the clearances and measure the shim sizes you'll need. I have the 3.9 in my own car....I wish the 4.08 was available at the time, I'd love to have it in my car!

I'll pm you the total today

I inquired with a very reputable local shop about installation of either 3.9 or 4.08 gears. What they told me was that they would advise against it because the tools needed for the install are not very common and Nissan no longer sells them.

I would find another shop then.
