YES both should still work, the car as i believe has a speed based cruise control and will only hold CC up to 90 mph the only difference is the rpms at each given speed... So maybe try to reset the ecu and relearn the Throttle? See if that helps.

I've put on over 15k miles with my 350evo 3.9 gears with no problems - VDC & cruise both fine & always have. I do change rear gear oil twice a year.... maybe a little overkill there, but it's all good

so what exactly are the "other install parts" people keep talking about. If i ordered the 3.9 FD for my car it comes with the ring and pinion and i have to buy something else also? Hope i don't sound dumb for asking this.

Pinion nut, pinion crush sleeve, pinion oil seal, and shims.
Some people will also choose to replace the bearings and bolts in there as well.

Now if you want to get up to 170+ you need FI, and if you go FI then the 3.9 gearing would probably not be a good idea on the car...you would be better off with the stock final drive or the auto one.

MPH = engine speed / transmission ratio / wheel rotations per mile * 60
MPH = RPM / tran gear ratio / fd ratio / ( 5280 / ( wheel diam " * pi / 12 ) ) * 60
123.38 mph = 6000 rpm / 1.000 {5th gear} / 3.538 {stock FD} / (5280 / (26.67" * 3.14159 / 12 )) * 60
MPH = RPM / tran gear ratio / fd ratio / ( 5280 / ( wheel diam " * pi / 12 ) ) * 60
123.38 mph = 6000 rpm / 1.000 {5th gear} / 3.538 {stock FD} / (5280 / (26.67" * 3.14159 / 12 )) * 60

Sweet!

Something like.... Yayyyy.....Boooooo. 
Hopefully they're giving you the hookup on the install.

It'll be fine, we came to an agreement on all the terms before even ordering a single part. I have no doubt in their technicians' ability to do the work, its more a matter of I'm the guinea pig for determining how long the job will take so they can estimate the job as accurately as possible for future customers.

Then again, I got the Nismo 3.9 since we were having clearance issues with the 350EVO one. Who knows if that makes a difference?
