Fuel management
I have finally installed my intercooler and need to start thinking about getting more fuel. I would like to run 15-20 lbs of boost, more if I can get away with it. What are some ideas for a good fuel management system? Is there something out there that is a boost controller and fuel management system all in one unit? I don't want to use just a rising rate FPR and not have any real control. I know I need to upgrade my injectors to 500-600cc. Where can I get those?
Also, I would like to post some pics in the gallery but can't figure out how
Could someone help with that too? I ain't real smart 'bout 'puters.
Thanks for any comments or suggestions!

Well, budget as well as your willingness to "play" will determine the best course for you to take. First and foremost, decide how much money you are willing to dedicate towards engine management. From there, visit some local tuning shops, and see what standalone units they use. While everyone loves to claim theirs is best, it comes down to the tuner. While many ecu's have hardware and software that is leaps and bounds above others, it all comes down to the person tuning it. A $10k Pectel doesn't amount to squat is the guy tuning it is clueless.
That being said, what are you looking for out of your car? On my ZX ('79, turbo's), we were able to run mid 12's on a stock block (non turbo), N42 head, stock manifold and downpipe, and a modded T3/T4. We concentrated our mods to the air flow meter, and were able to get significant gains here. We also coupled this to a very capable Bosch pump, as well as 480cc injectors, and a Starion FMIC.
When the time came to turn up the wick, we went with Electromotive, and have since become a dealer. It allows you full control over fuel and ignition curves, and can do boost if you so choose (though I use an EVC IV to do boost..I prefer a standalone controller). We now run 20 plus psi on a full T4, HUGE FMIC, etc. All in, a TEC3 will run you around $2500 or so. Injectors are fairly easy to come by, depending on your rail configuration. Right now, we are tuning the new setup in my car, since the turbo, IC, and motor are all new to me (we finally did a built motor, cam, massive head work...fully done). I ams ticking with the 480's for now until we get it all dialed in, then we will be building a custom rail and using 720cc injectors, which we have already.

Hey, thanks for the reply. Your car is beautiful!
Low to mid 12s is about where I'd like to be, I guess. I will mainly be doing autocross and maybe some road racing. I like to turn. I figure 450-500whp should be enough. The main thing is I want the boost to be stable and the ratio stoich. I plan on upgrading the turbo to the t3/04 hybrid, eventually and also adding a 75 shot bottle for those occassional quarter miles and street races. I was hoping to keep the cost of the ECU under a grand but if that can't be done for my application I'll just work some overtime and get what I need to do it right. One thing I don't want to do is cut corners and blow the whole thing to smithereens, then have to start all over. I have already wrecked the car once and fixxing that has slowed the process considerably.
As far as the speedshops, well, here in Chattanooga, they are almost non-existant. If it's not a Honda they pretty much acan't help ya. I'm going to have to rely on mail order and info I can get from people online who have already done it.
Here are some pics of my unfinished project...

ive brought a LINK engine management system for my car, cost was $1400 new zealand dollars ($700 us dollars) does everything you will probably need, no where near the best but has been used in 850hp drag skylines down here
to have a bit more of a read go to this website http://www.link-electro.co.nz/home.html
i havent yet had the time to to work on my car so i dont have it running, but looks easy as to install, and you dont need a laptop to tune it.
good luck with your car its looking better then mine is at the moment.

A question about the standalone fuel management system for those people in California. Is it able to pass smog? Just wondering b/c for an ECU setup from JWT is 600 bucks give or take and SDS standalone is only a few hundred more. Thanks.

What you are looking at is the computer that runs the car. it is an Electromotive Tec II. Though it has since been replaced in Electromotive's range as the TEC III, you can read about it at www.getfuelinjected.com, or on our site, www.z1auto.com
Basically, it is fully mappable fuel and ignition, that requires a laptop. Easily the single best mod I did to the car.
Wheels are Simmons custom forged 3 piece units; 18x8 up front with 245/40/18's, and 18x9.5 rear, with 285/35/18. Tires are P Zero Asymetrico's.

So the wheels are custom made for your car with the correct offset, right?
They look like Koing Imagine wheels. I like them a lot too, but the Koing wheels require the 38mm spacer for a Z. Your wheels have the deep dish that RWD cars were known for. The 350Z looks like it has a big positive offset wheel now...

yes the wheels were custom done for my car, as are all Simmons wheels (liek Fikse, HRE, and a few others).
I went to a Simmons dealer our shop deals with, and they spent 2 hous on a buddies 280 ZX we have ton alot of work on (a turbo conversion like mine used to be), taking meaurements, etc. When the wheels showed up about 6 weeks later, they were exactly what a good wheel should be...no spacers needed. Size is 18x8.5 front, 18x9.5 rear, with 245/40/18 front and 285/30/18 rear P Zero's. They are also full forged and 3 piece units...cost me alot, but were well worth it. They are just as you described..a deeper dish (aka staggered) rear than in the front.
Ecu is an Electromotive TEC2 (we are their NY dealer). I will be moving to the TEC3 soon, as the TEC2 is going to one of the guys that works for us, who has an immaculate yellow '77 with a nice custom turbo setup.
