I'm a little fuzzy on the details, but I talked with performance nissan a couple years ago and I think they said the 3.3 FD will fit in the 6MT housing, but you had to use a 6MT LSD with the 6MT diff
I believe you can also put the 3.5 FD inside the 5AT's diff as well, but you'll have to use a 5AT diff that fits the smaller 5AT diff

You still need to pair a 3.538 diff with the ring gear, and like wise for the 3.357. The ring gears are 2 different thicknesses, and the diffs are designed appropriately for each.
I have the 3.357 housing, that was rebuilt using the 3.917 ring gear and a Quaife designed for the 3.538. Its a lot more complex than a ring gear swap, or diff swap. Its feasible, but it requires a complete rebuild, ground up. The only reason we took this route was because my donor diff was an '03 3.538 and the companion flange wasn't mating to the driveshaft on my '05. So we had to take parts from both diffs to rebuild my '05 3.357. Its time consuming and not an easy task. It was a real testement to how good a mechanic Frank at AAM is.
What I don't get is why everybody who steps from the 3.538 to the 3.357 stays with the weak *** VLSD. Its basically an open diff with training wheels.

We just installed the 3.3 gears in our 6mt diff with the cusco LSD in the Time Attack race car, that along with the new power (twin JWT BB 850's ) should be a good combination.

We will see in about a week . Car gets dynoed & tuned on friday, then off to the track to test everything next weekend.

Please keep us inform on how the 3.3 works on the road course, as I am getting ready to throw in a 3.3. Are only concern was that is might be a little laggey for road course use, but with high Hp i think that should not be an issue. JWT BB 850's is that the Garrett Gt 28/30 turbos??

And I will update you on how I like the 3.3 FD gears at Willow Springs. We have now tried the 3.91's and the 3.50's and I learned real quick (at least for me) the car loved the taller ratios, so it should be even better with the 3.33's.

IYO you think the 3.3 is going to be the way to go on the road course? Well I hope so, cuz I have one ready to put in with ATS LSD.

We can usually get within a few WHP (corrected) give or take, between 3-5 local dyno's (DynaPack, Dyno Dynamics, and Dyno Jets). They are calibrated frequently and are owned and opperated by a few different shops. The new turbo's are going to start at 17 PSI (waste gate springs) and we will build up from there once we get some other stuff dialed in and a better clutch . The increased efficiency should also help with the heat issues this Summer.
