I am considering tuning my 2010 GTR. It has around 20k miles, all road miles. No track.

Package I'm considering Switzer P800 or maybe AMS 9. Few questions to members that have / had this package or know well about this package.

1. How long with normal driving, once in a while acceleration 0 to 80, or 60 to 120 would transmission last? I just want to have an idea.

2. How much more louder the car becomes with this tuning? How about the noise inside the car?

3. Any other modifications are recommended with this tuning?

4. Are there any other things I should know about having this tune?

5. Would there be any big difference if I tune 2012 or 2010 GTR with one of these packages above?

Contact Bullo, his P800 was one of the first and still to this day is running strong on stock everything. Infact he uses it as his track car.

1. How long with normal driving, once in a while acceleration 0 to 80, or 60 to 120 would transmission last? I just want to have an idea.

The tranny should last a really long time with that type of driving. We have 10+ customers running 700+ whp on the stock tranny and its doing just fine. Just as long as your tunner keeps the boost turned down a bit in first gear you will be ok. I think the most miles we have on one right now is about 35k.

2. How much more louder the car becomes with this tuning? How about the noise inside the car?

That really depends on the exhaust you choose. You can use a resonated mid pipe which honestly keeps it pretty tame, the noise/sound is very bearable for daily driving.

3. Any other modifications are recommended with this tuning?

Depending on how hard you want to push things, and who you have tuning it a built motor is optional, and obviously all of the supporting mods for the turbos.

4. Are there any other things I should know about having this tune?

Not really, a GT-R at that mod level is actually a very tame street car...you will really enjoy it.

5. Would there be any big difference if I tune 2012 or 2010 GTR with one of these packages above?

Not at all. As long as you upgrade the turbo inlets the car will be exactly the same. The only difference is that the 2012 tranny is built just a tish <---technical term
better...but you will likely never know that.
