Why did you opted for now on a proper return fuel system? Sure with a good build and proper tune you should be fine but honestly you should have install that fuel return. Rated 720 cc injectors and 320 lph fuel pump plus lowering the compression you will have to push the turbos harder to reach lets say 500whp than someone with 11.1 compression ratio. I lower the compression on mine and i didn't skip on a return fuel system and believe me is harder to reach the numbers you want. Your limiting factor right is what will help you the most achiving what you want....FUEL!

Builder / tuner said it probably won't be needed for < 600whp even on 9.5:1 compression.

Honestly I'd get your car out of that shop as soon as possible! 13 months for a tuner who doesn't know anything about 370Z's?

I've built a GTR from the bottom up including a new fuel system, flex fuel, new turbos, engine dismantled to the short block and sent out to be rebuilt, shipped back and assembled by myself and then tuned all within 6 weeks.

Don't make the mistake many others have done and keep it in a shop rotting away. I haven't seen a 13 month build in a while unless it's a completely custom car..

Hopefully this won’t be another case of I told you so. Judging from his comments he knows just as much as his tuner/ builder about the z34 chassis. Darn shame

I would feel more comfortable with a Aeromotive 340lph and 1,000cc injectors and still i wouldn't aim for 600whp without a return fuel system since also lowering your compression you will need more boost than someone with an 11.1 ratio and you will hit a wall with the fuel aspect! Just my opinion
