Smile 350Z LSX conversion

I'm finally starting on my 350Z build. It's an 03 six speed touring model. I have a 02 LS6 with ported LS6 heads,cam, ported ls6 intake and tb. I've just received my conversion kit from Sikky and let me tell you they have great customer service. Here's is what I got from them.
-8qt sheetmetal oil pan with oil filter relocation kit
-Drive shaft
-1 7/8 headers
-engine and tranny mounts
-Master cylinder
-Billet shifter
I'll post pic's as soon as I learn how lol. This is my first time building something like this so I'am going to have many questions so if you guys who have done this conversion can give me some impute that would be great.

Well I've pulled the stock engine out and I've also removed the engine wiring harness.I was under the impression that the stock computer had to stay in the car which it still remains in the car? I'll be using Auto meters gauges all around. How do I go by pluming the fuel system?

your nissan ecu will need to be tuned to let all your guages etc work and the lsx computer will run jsut the vitals of the car (or so this is how I understand it)

idk about on the pump/tank side, but you should be able to use stock or aftermarket rails.. if youre not going with crazy power levels and its designed for it id stick with the factory returnless stuff (fpr/rails). Less money and hassle.

I used the stock gas pedal. It was actually quite easy to modify. I removed the stock pedal position sensor and bracket and then welded a small piece of u-channel steel to the main pedal rod. Drilled a hole in the u-channel and it was good to go.

Are you going to be using an IAC?

You will need to lengthen the travel of the gas pedal by a half inch then. Easy to do though. Just cut a half inch out of the stock 350z bump stop on the bottom of the pedal and weld it back together.
