I have some ?s
Ok, i have a '05 5at coupe, i'm wondering what type of FI i should do? If any? How reliable as a daily driver? How much installed? Where could i get it done in AZ? Is it really worth it? Please send pics or Dyno-sheets, im wanting to do my research before i spend the money!!! So any of your help and advice/imput would really help.
Ok....first. Take your time and research. From what you have said...I was in the same boat. 2005 AT Coupe and my daily driver. We all know Turbos will give you a bit more performance....but...they seem to push the VQ to its limit. After all said and done, I decided to get a Supercharger as the power comes lineraly. The Vortech has a good track record around here. You must unerstand though that any FI application is a risk on your engine and drivetrain.
After all said and done...my Vortech install and tune with the Zeitronix gauges and some other items at CP Racing in North Carolina came to about $7000.00.
Here is my Dyno sheet:
Is it worth it? YES. 7 grand is a lot of money but it performes like a Vette or M3 now.
As for the AT tranny....you will want to do some extra things to it. Everyone recommends 3 things. A valve body upgrade, torque converter upgrade and a tranny cooler. Here is a copy of a post I did a while back:
"Forgot to mention that if you have an AT...there are three additional precautionary things you can do to help save your tranny from the newfound stress: (I am just learning these so if I am mistaken, please somebody correct me as I hate to give out incorrect info)
1. Valve Body Upgrade - This modification tinkers with the pressure and springs inside the tranny to firm up the shifting. Our cars are set with a soft luxury type shifting. This is great for your grandmother's Cadillac but not good in FI applications. I also believe it creates more heat during that time it is engaging so by firming it up, it helps keep it cooler. More on heat later on. As of now, Stillen, Level 10 and SGP make the VB upgrade for our tranny's. Lets take them in order to save you some searching time.
a. Stillen is decent but folks who have gotten the upgrade have not seen that much of a change in firmness. Most feel the firmness on the downshifting (in MM Mode).
b. Level 10 makes one but have a bad reputation. Both in the product and in the customer service arena. I would avoid them if possible.
c. SGP makes a valve body but couldn't find anybody who had one on. Though SGP is very reputable around these forums. They have, however, in the last couple of days, announced that they are making a complete overhaul of the VB and not just making simple changes (ala Level 10 and Stillen). This is most likely going to be your best option, however, SGP has yet to announce its availability and pricing just yet. Stay tuned. The test mule right now is GrugenPB and you can find his posts about this new valve body here:

Both threads have videos to download (both in MM Mode and Auto Mode).
2. Next tranny mod to learn about is the Torque Converter. I know even less about TC than VB but I'll give it a shot. The TC will be most beneficial from a dead stop (ala drag strip or stop light). It lets you set higher stall RPM's and transfer the energy quicker. Some folks on here are very knowledgable when it comes to stall settings and TC. Find them and ask. Two reputable companies who can help with a TC upgrade is Protorque and Edge Racing. TC can also alleviate heat form the tranny. There are two main things that kill our AT's; Too much torque and heat. Since you are getting the Vortech (as am I), too much torque probably wont be an issue as that really affects the turbo guys. But heat will be an issue for most FI applications. Which leads us to mod #3.
3. Tranny Cooler. These are relatively cheap and can help keep your tranny cool. There are many different kinds and different sizes available. I bought the 24,000 GVW B&M model from jegs.com:

I know I just barely scratched the surface, but I hope this helps you. There are many threads about these mods and I certainly urge you to read up and learn about them. And if I have made any mistakes...please correct me. Thanks."

Interesting-- I figured that there would be something you'd have to do with the AT.
How much should it be to get the tranny good to go with some kind of FI application.
Is there any other parts of the car you should upgrade before dropping in a FI application?

My car is fully stock except I bought Crawford h/f Cats and had them installed at the same time as the Vortech. The tranny is probably good enough as it is for the FI application but if you are gonna beat on your tranny for a long time to come, you should get these 3 things. I already did the tranny cooler as it only cost me $50 bucks...cheap insurance. The VB will be coming sooner or later. SGP emailed me back with a price quote of about $1200 bucks for their new VBU. OUCH!! As for the torque converter....I don't yet know if its worth the $1000 bucks itll cost to buy it and install it. There are many threads on FI and the AT. You should also check out the FI forum on www.my350z.com. Same engine and tranny on the 350z and a lot more FI posts over there.
