Go bigger on the fuel pump. Get the 340. Headroom in the fuel system is a good thing.

I'd recommend 750cc injectors too

Low mount is going to be better. Twins are really better on a v engine from a packaging standpoint, but you have to pull the motor to install.

Keeping a hot turbo in the engine bay of a car with cooling issues stock is a bad idea, not to mention I'm not a fan of how you have to run the hot side piping. Low and out of the engine bay is better from a heat and piping standpoint.

Stock gtr injectors are 570cc, paired with a 255 you will have more than enough fuel for 500whp on gas. (I made over 600whp on a low compression vq with the exact setup). I personally think the stock y pipe and cat back would be fine for 500hp. Obviously there would be benefits on going bigger.

Still on stock internals?

This is from my friend's 370z that was just finished. It made for 500 whp at 7 psi but I am always concerned about dirt going in the turbo or even bottoming out.

That's where mine is give or take a couple inches. Filter protects the intact and the turbo itself sits above the subframe so no bottoming out.

Check out my build thread. It has a lot of detail.

Oh nice I just looked over your thread. Really well done! Can you still hear the turbo really well? I like hearing it spool.

jwick · 12-27-2015, 06:46 PM

Oh yeah. It's more prominent than in a TT setup. You hear all the spooling and compressor unloading. It's wonderful.

TopgunZ · 12-27-2015, 08:19 PM

I've had both the top mount turbo using a gt35 and the mid/ bottom mount. Let's discuss heat.

Now I'm not a track star and have barely ran my car autox . With my top mount on the street I had never once overheated with the stock radiator on my 350z. Now to make that even more interesting I added a supercharger to that turbo. It was a pd roots. All smashed under my hood. Guess what, never overheated in summer. Remind you I only boosted from stop light to stop light and on ramps and in open interstate situations.

The bp kit also never overheated on me. I've always had aftermarket front bumpers with huge mouths, both stillens.

Interesting notes, I've always only ran e85.

Also, the bp kit does sound incredible. The spool was awesome. My powerlab gt35 never came close. I don't know if it's the turbo or the placement but bp wins there. The vsr kit uses the same turbo so I don't know how it sounds in the top position cuz I've never heard it in person.

These cars dont need aftermarket radiators. The stock cooling system is perfectly fine for a street car. Not sure why everone swaps them out. One guy probably did so now everyone thinks they need it.

Someone please help the OP out.........he/she is going to be posting about how they are having problems later on if they go through with what was posted previously. I see not much has changed since I have been in and out for a year and a half...........

You better off getting the stillen supercharger OP. for the numbers you looking at and how conservative u tryna get. The stillen surcharger will provide that fun for u and you can keep your car as stock as you want.

Supercharger makes its reliable and have linear power but I am not going to lie, I am in it for the turbo sounds and bov, etc. Not even interested in power gains as dumb as that sounds. LOL
