Well, the build is all done and the fun lasted about 700 miles before all the problems started. I drove it around for 500 miles N/A and then put the supercharger back on. The engine is working great and sounds awesome. The car won't start on its own now. When I crank it the engine just floods. I replaced the cam pos sensor and the harness/clip thinking I might have bumped it during the supercharger install but that didn't solve the problem. I also swapped mafs and that wasn't it either. I'm not getting any codes at the moment. When it first wouldn't start the plugs were soaked and I HAD to get the car running so I checked the codes and it threw a cam pos sensor and a maf code. I then compression started it and it ran totally fine. Drove 30 more miles that night without any problems. I am completely lost on what this problem is. The other day I compression started it and it was not happy. When I gave it gas (while barely running) it would try to die, then when I let off the gas it would revup/go back to idle. I am going to check all the maf wiring tomorrow. I am pretty sure it is ignition related but I just can't figure it out. Any help would be greatly appreciated, it has been almost a year since it has ran correctly/ran at all and I need it to run.
Thanks,
Zac

I can help you diagnose the car in person and I'm not very far away. I bet I could figure it out too. lol.

Thanks 505!
Is it possible that my battery is bad and is what is causing the weird electrical issues? I am going to look at every wire in the wire harness and check all my grounds tomorrow. Anyone have an idea? I am stumped

J/K I hope you get it figured out but I have had minor electrical issues in the past, wires no longer giving continuity, etc.

Your starter cranks, right? If so, then it's not your battery. I'd check continuity on all of the wires that have been spliced before and I'd check all of your grounds. Hopefully you can figure it out soon so you can get that beast back on the road.

Well I am really late on this update, but here it is. The engine is running great, no bad noises, etc. The tune however, is WAY off 
I am currently running a JWT ECU with a tune for the supercharger and a stock VQ35. The compression ratio went from 10.3:1 to 8.8:1 while the tune stayed the same; basically the car is lazy as all hell. The new chip is being programmed and I will have it soon. The problems I had right after the motor went in were finally solved as well. The starter would crank and pass the test at shmucks, but it was bad. The battery AND alternator went out at the same time as the starter, just my luck. 
I am trying to decide if I want to raise my rev limit. It's currently at 7200 but I was thinking 7600-8000. Any thoughts on this would be appreciated.
I will say that there's nothing like driving a boosted VQ35 again

I am guessing your motor is built and has upgraded bearing and oil pump but if not then I would leave the rev limit alone. For now 7600 may feel great but over time I am pretty sure you'll be in the same position as me

I wish I had kept the EMU, oh well.
I don't plan on pinging the rev limit very often at all. I just would like to know if I want to, I have to option to rev that high. I figured the motor would handle it after I built it, but I wouldn't ever go to 8k and up. I have thought about reinstalling a nitrous kit on the car, maybe I will just do that.
This is the build list, so yes it is built.
1. Low mileage crankshaft (I bent mine when I spun the rod bearing)
2. Wiseco Pistons, 8.8:1 96mm
3. Eagle Rods
4. ARP Rod Bolts (Included w/Rods)
5. Debuloz Camshafts (S1 Knockoffs)
6. JWT Valve Springs & Retainer clips
7. New 350z Revup Oil Pump
8. NWP Spacer Kit
9. Slightly used 2.87" pulley (Hopefully will prevent slip)
10. Cometic Headgaskets
11. New Waterpump
12. New gasket set for the entire engine
13. ACL Race Series Rod, Main, and Thrust Bearings (Stock Size)

I think I am going to stick with 7500 and not go any higher than that. I've had good luck with my transmission, knock on wood, but I know it has to run out eventually. 180,000 miles and it's been through nitrous, VQ35 and nitrous, and the current setup over the last 40,000. Can the 6 speed transmissions handle the higher rpms better? I know they have the HLSD, which is something I would really like to have.

Looks good so far. I might be going with same pistons in my vg33 if I can use them. I know the wrist pin is same size but got to find out center of pin to dome height and bottom of skirt. In for updates as it comes together.

This is awesome, its great to see more and more engine builds here, I get lonely lol.
You gotta remember that revving way high is not always the best, you gotta know what your powerband looks like, although since your SC I assume you'll get getting more and more boost as RPM's go up, but if power is less at 8k then 7k then why rev all the way to 8k.
What weight oil are you using btw? and what Manifold?

When I talked to JWT, the tech said it depends on the cams. He said 8,000+ would be fine with the S2's but he was going to check on the S1's. I have been running 5w30 for now, but I think I'm going to run 10w30 once I get the chip and new tensioner. I have the 04 Maxima manifold with the NWP VIAS block plate, I didn't do the ssim either.
