Does this look about right, shopping list

[turbolence46]

I do trust science of speed, but just wanted a second opinion to make sure I'm getting everything I need.

Just want to check with you guys, does this look about right, placing an order with SoS, their qoute.

Posted this under NSX owner discussion, but it might fit better here. Briefly,

1996 NSX, 6spd, 106k, High Boost CTSC, H/I/E/, clutch. Running extremely lean under boost according to dyno tuner, I'm just going to do it right and rework the whole fuel set up with a AEM EMS.

Any changes you would make? does this look complete? Any omissions? Thinking I might be able to get close to 400whp, but I wont be disappointed if I'm a little short. I just want a second opinion since this is a lot of money. Thanks

For 400rwhp, do you really need 1000cc injectors? What are your current injectors? Couldn't your dyno tuner richen up the mix? Are you currently running a stock original fuel pump?
If so, that alone could be your problem.

My turbo setup was getting a little lean, I changed to a walbro 255, fixed the problem.

The reason why everyone these days are pushing for ID1000's is because it is an awesome injector. The are probably the best. I have them on my Civic, with Skunk2 pro 1 cams and the car idles at 850 rpm. They are a great injector. Will idle great like stock but ramp up as needed. They can also run really high fuel pressures which sometimes can be useful.

The stock injectors are close to maxed out, even for an NA application.

The ID1000s are awesome injectors, and the EMS will be able to manage them fine.

The car should idle better than ever.

Thanks for the input guys, after talking with science of speed I made a few changes, but keeping most of it. I can't wait to get this all together! Ugh the fuel pump install though ... FML

What changes did you make?

I didn't drop my tank and installed a radium auto surge tank. Install was super easy about two hours, including the wiring, attaching my own lines and fittings. Thank god I did this because my fuel pump died the next day and I would have had to drop the tank again. It's super easy to upgrade in the future, supports single or dual walbro, 340s, 044s etc. no rewiring the stock fuel pump required. Setup works flawlessly if you want more info let me know.

Yeah, dropping the tank was the hardest thing I've done to my NSX. Probably because I did it by myself and on my back.

Well against your better judgment, I went with the 550s. It saved me about 500 bucks since it requires no adapters, no resistor bipass, and they are cheaper. I only made this decision after talking with SoS for a bit on the phone yesterday. They all agree ID1000s are fantastic injectors, and that it will work with my setup. He did highly recommend the 550s though for my 400whp goal. The ID1000 would be running at a much lower duty cycle, and would take quite a few more tuning hours to get it dialed in perfectly for daily driving. At 120 an hour, it'll add up quite a bit. SoS uses 550s in all of there high boost CTSC set ups that are hitting 400hp, so after all that talk, it seemed like a wise decision. If it ends up I'm unhappy about the purchase, I'll have to take the hit and go for the upgrades, but my goal of 400whp is the max I want to go. I mentioned I felt the 550s were a bit dated, but they assured me they will work perfectly for goals and set up and they are quality injectors.

I'm unfamiliar about this set up, what does it involve? Any benefits besides the labor exclusion?

Is the OEM FPR not good on the NSX or do the 550s require a certain pressure? On previous Hondas I've built the OEM FPR is typically left until around the 500 whp mark or when pressure needs to be increased to compensate for injector specifics.

How it works:

Your stock fuel pump stays in the tank and supplies fuel to the surge tank and keeps it full almost all the time. The stock fuel pump will not have any resistance against it so it can flow a bit more than it normally would. We remove the stock fuel line between the fuel filter and the rail and use our own lines and run it to the surge tank. The fuel pump inside the surge tank now becomes our engine supply pump, this pump will supply fuel under pressure to the fuel rail. The stock return line coming from the fuel pressure regulator will now return to the surge tank instead of the stock tank, this helps ensure the surge tank is topped off. Finally the top most line on the fuel surge tank will return any overflow back to the stock fuel tank through the factory return lines.

There are plenty of advantages. One of the biggest of course you and I already mentioned the easy and quick installation. A few others include no worry about tank slosh for track days. With the cylinder angled upright even in hard cornering the surge tank won't starve under the g forces. Even if the stock tank is starved the engine will still have fuel. It has it's own relayed power supply so you don't have to cut into the factory fuel pump wiring. It is very easy to upgrade if needed in the future. Adding or changing out a fuel pump is a simple and quick affair, although most people just drop in a walbro 255 and call it a day. For big power setups it can save some money potentially over sumping the stock tank or installing a double pumper kit but for small simple applications under 500whp the cost of a surge tank setup may not be worth it. Some people that were thinking about having someone else install the pump could save some labor costs and install something like this themselves. I do most of the work on my car without any help and dropping the tank is not a simple affair. Easy to take out, convert back to stock and use on another car with a few different fittings. It's not for everyone but for me I love this type of system. There are a few surge tanks out there but the radium auto is one of the best quality auto pieces I've used and highly recommend it. A setup with a single walbro would cost roughly 800-900.

I just read up on it, that is a real clean install, says it about 500 or so, since I already got the pump. That's almost kinda tempting, I guess it all depends if I can get a spot that allows me to do the work. My garage is somewhat impossibly cluttered.

The car had the FMU on it from the CTSC kit, I don't have a stock FPR, so I figured I'd just swap the FMU with the Aeromotive
