Thinking of going Stillen S/C

TurboXS has spent the last couple of months developing an EMS solution for the 350Z Market. Fresh to the Z market we release the Z UTEC. This unit will be available for the 350Z and G35.
The Z UTEC is a Plug and Play Parallel Engine Management System. Designed to work together with you factory ECU. The UTEC gives you the ability to let the factory ECU drive the car under normal cruise conditions then take over when you are ready for the power in a flawless manor. This gives you like stock drive-ability with the advantages of a powerful stand-alone system. The UTEC allows you to maintain OBDII compliancy as well. The UTEC is unnoticeable to the OBD Scan process most states are adopting these days. In basic form we allow control over Fuel and Ignition Timing. Each control gives you 250 rpm resolution from 500 rpm to revlimit with over 10 different load sites. The UTEC will ship with pre-programmed base maps to help get you up and driving right away. In addition to having a pre-programmed base maps the UTEC has provisions for 5 different map locations. The multi-map capability allows you to use our remote map selector to switch between the 5 maps or stock mode on the fly. Your tuning options are endless when you can have a race map and daily driving map at the tip of your fingers. The power is all yours!
The easiest way to visualize it would be to break down it’s components into separate systems.
Fuel Control- The UTEC takes control of your vehicles fuelling at a define-able TPS point that is programmable. Fuel is tuned by an MAF offset table, a simple but effective technique. The load reference we use is RPM vs. MAF Voltage. The UTEC can also take in our optional MAP sensor to tune RPM vs. MAP or you can just use the MAP reading in your datalogs. This allows the fuel map to be adjusted at each of the 250 rpm resolution with over 10 different load sites from zero to rev limit.
Ignition Timing- The UTEC gives you complete control of timing. This is not done on the basis of offsets or altering the crank signal as some engine management systems use. The load reference we use is RPM vs. MAF or MAP which is optional. This allows the fuel map to be adjusted at each of the 250 rpm resolution with over 10 different load sites from zero to rev limit. When you enter a value into the Ignition Map you are actually typing in Degrees Before Top Dead Center. The UTEC fires the coils based on these values. No more wondering if the stock ecu is going to advance or retard timing.
Knock Control- This feature allows you to help keep your motor in one piece. The UTEC contains default knock thresholds but can be adjusted at 1000 rpm increments up to 9000 rpm. It also contains a Knock Count threshold that allows you to define how many counts of knock before the UTEC will respond with a Knock Retard Step. The Knock Retard Step is the amount of ignition timing that will be pulled per knock count to a defined Knock Maximum Retard. Knock Maximum Retard relates to the maximum degrees of timing the UTEC will retard per knock event. When a knock count is registered the UTEC will hold the retard for a set number of crank cycles this is called Knock Retard Duration. The UTEC also has the ability to apply a global Knock Correction to the entire map once a knock event is evident. This will help ensure that you keep your high compression monster together. All of these features are the UTEC’s safety net. They should be used pro-active not as a reactive measure.
Datalogging- The UTEC Datalogging function helps you to keep an eye on your engines vitals. Using the logger gives you all the information you want to know about your vehicle. You can take multiple logs of your vehicle whether it’s simple driveability or all out racing. You can be sure the UTEC is keeping an eye out when you can’t. The main logger (Number1) contains rpm, map, maf voltage, tps, load site, afr, ignition timing, injector duty cycle, modified fuel (fuel control) and more. Logs can be output into text files or csv files for easy comparison. When the UTEC is used with a TXS Tuner model it can also supply you with w/b afr readings in your logs as well. Giving you the ultimate tuning package.
Remote Map Selector- The remote selector gives you the capability to switch between your UTEC maps. It also allows you to revert back to full stock ecu control on map 0 (when stock sized injectors are used). Maps 1 through 5 are your UTEC tunable map locations. Map 7 is your security mode, the car will not start. The car cannot be bump started or jumped when security mode is enabled
Software Upgrade- The UTEC will have periodic software updates to further innovate it’s tunability and flexibility. The most current version of software will be available on our website www.turboxs.com.
The Z UTEC will be ideal for both Forced Induction and Naturally Aspirated Mods. The UTEC has the ability to control things like Nitrous, Water Injection and More!
We will be shipping units out to selected testers in the next couple of days. We have been running them on our in house vehicles with great results. On a Z with test pipes and intake we are seeing 10-13whp gains and 9-12 ft. lbs. gains in the midrange.

I don't know if I want to deal with all of that bolt-on-stuff, I would rather just leave my car stock in that case.
Like someone already posted if the stillen was $1500, hell even $2500, it would be a good deal. Too bad after install and the new hood and paint you are looking at almost 3 times that amount. Not worth it IMO.

simple bolts on that you can do yourself.....pop charger, test pipes, exhaust, plenum spacer or plenum, and UTEC. Have a tuner do the pulley and tune. Like a said you will get about the same results for a lot less money. If you just want the stillen to say you are FI'ed, have a blow and the sound....then go for it, but you won't have that much power.

If you want something easy, the simple answer is Bolt-ons. You can't look at an aftermarket FI unit as "Easy" or not needing any maintenence on a NA car. I honestly think you might want to look into Bolt-Ons, or maybe a Centrifugal. If there warranty covers the engine, do you know anyone who has blown their motor and Stillen has repaired and replaced their engine?

Edit: I just looked at Stillen's website, the Stage 2 Supercharger is $5,765.00!!!!!, please please look into a Vortech or do Bolt-ons, I didn't even think it was priced THAT high.

+ 800 - 1000 install so that's around $6,300 + Hood (i think $300 )= $6,500
after doing the math
Crawford Headers = 980
Crawford HFC = 500
HKS Exhaust = 1400
Iso thermal spacer = 300
Modified lower plenum (Mrev+) = 140 (has been dynoed to help non-revup motor)
UTEC/Tune = 1400+
Install will be around $1000+ for headers/HFC/Exhaust (MREV/Spacer can be done by your self)
That's about 5.7k+, this should be the same HP but will have less torque than a Stillen SC Stage 2.
I guess for less than $1,000 more you'll get that extra torque and nice pimp factor. Well minus - for ugly hood though.
