Hey guys.. I am new to this site so please bare with me.. I sold my 07 mustang gt and got a 2012 g37.. I love the handling but miss my torque.. Is it possible to get my 37 to around 400hp and increase the torque a bit while staying naturally aspirated? If so what would your recommendations be? I do not want to do nitrous ... Thank guys

 

Forced induction is your answer, my friend.

 

unfortunately there are no bolt ons that you can pile up to get 400hp

 

But it was so easy on the mustang!! ... Damn hAha thanks guys

 

320 on a good day is about all you will get without spray or FI.

 

Ok so what should I do to get the car ready for a supercharger ... What's the best exhaust system for these cars?

 

Yeah with a good combo of bolt ons, a tune, and maybe come lighter drivetrain components you could probably get to about 330 at the wheels but not more than that, especially on auto. Low end torque isn't the G's strong suit not much you can do to change that. It's just the way the engine is designed.

 

V8!
Those new 5.0's are the beasts though ..
Welcome to the forum.

I agree for 400hp you'll need TT, SC or N02

Exhausts it depends on your budget, how much were you looking to spend?
Full exhaust, axle back?

 

If you're looking for low end torque with OEM driveability I'd invest in a GTM S/C. Otherwise, a TT is your way to go.

If you want to stay N/A, then the 4.2L stroker kit from GTM with increased CR will definitely put a smile on your face, you wallet won't be smiling however.

 

Like many of the people said 400 HP just with bolt on's is madness. Most I've seen is 325-330 on here. So like many of the people said get F/I kit, also remember the G's weren't made to be a race car. Our cars were made as a luxury with a little kick to it.
