I have been told a water to air inner cooler could help, or an oil cooler. maybe bigger throttlebodys?

My big reason for staying away from FI is the huge cost, and needing to do cam/rod/piston work if I break 400WHP according to Rob. if I want a daily driver that will last me for 5-10 years, I can't or shouldn't do FI without engine work. At that point, I bought the wrong car and should have just gotten a GTR.

Rob told me that our motors can swing 400-425WHP without any engine work safely. After that, it's up in the air.

So lightweight pulleys are safe to use then? Minimal gains i'm sure but, I think at this point everything I do to get my 350WHP will all be minimal gains.

Now if I could find a supercharger used or cheap for 3000-4500k... I just might have to do it.....
400-425?! Unless your driving a G35 you'll be fine at 500-525 .. There are guys running close to 600 on stock block without any problems.
May wanna check into a lightweight driveshaft for more power..

Also want a supercharger :P

If you can get one for 3-4k , are you planing to install it yourself?
If not it probably would cost you another 1k, and than tuning around $600 , so you will still spend around 5k~+/-

Its up to yo tho

Well at this point it sounds like a carbon fiber driveshaft and lightweight pulleys should get me near what I want. Not sure if both alone will give me another 22 WHP.

So no opinions on oilcooler or water-air innercooler?

Can superchargers even be had for under $4k?

Are you pulling our leg? I just have a feeling you are... in case you aren't:

First, it's inTercooler. And I'm sure you know this, but since you are not running forced induction, all an intercooler will do is increase your intake tract volume.

An oil cooler won't give you more power either, but you need one if you are going to track the car.

If you get the carbon fiber drive shaft alone i hope you dyno it. I dont know what they make on the 2007+ Gs. The 1st get shown a gain of 15 hp at the most.

I say someone buys this and do a before and after dyno to see if this is the real deal.
