Oh, I saw the 340 at the start of your thread and assumed that's what you started with.

Hmm, knowing that, I'll definitely wait and see. I'm using 750cc injectors with the 340lph fuel pump. I'll be getting tuned soon and will post up the info in a separate thread.

I don't know why I'm not subbed yet. I click here every damn day lol.

The 255lph fuel pumps have a limit of abot 500-550whp (on the VQ35/37 engines), depending on the dyno. I don't know why any forced induction kit would use those pumps these days when the 340lph fuel pumps are available everywhere. IMO it is a bad way to keep the kit cost down.

agreed, I wish I had known about the aeromotive stealth pump last year when I originally installed the kit. an added benefit of this pump is in its name, its so quiet!

Damn, Nick! Those are some killer numbers at 12psi. What are you looking to run once you get retuned? I hope you say 15-16psi...would love to see what those turbos can do.

as much as I can on 93, from what I've seen with a VHR at 10:1 thats about 16-17psi

Only 650cc injectors? I have the ID1000s, Aeromotive FP, and a return system. All I need now is forged internals, a little intake tweaking, and more boost. I really need to get my pennies together now, so I can join the built boosted club, lol.

Now we are talking

Hey Nick, on this google doc you created:

https://docs.google.com/spreadsheet/...DMWtBT0E#gid=0

Are all those parts included on the OEM gasket kit that you can get for about $200ish? I know the oil pump and timing components are not, but how about what above them on the list?

How's the car doing?!

it might be, but at the time when I ordered it courtesy couldn't find the "gasket set", if you can get it that should cover you.

my Z is back in the shop unfortunately, looks like I lifted the head last week probably from overheating. my car has been plagued with overheating issues all summer since I turned up the boost. I switched to a mishimoto radiator and added a 2012+ expansion tank which helped a bit, but doing 2-3 back to back pulls the car would overheat, even in cool temperatures.

I suspect that the turbos are boiling coolant creating air pockets in the cooling system due to how GTM routed the turbo lines: coolant output of passenger is coolant input of driver, so driver side turbo is being cooled with very hot coolant.

Ron · 10-25-2013, 10:17 PM

oh man, that sucks, I hope you can get it figured out. Are you going to tun independent cooling lines for each turbo?
