It all depends... Unichip or E=Manage, Price, Expandability, they all are factors... #1 suggestion... read, search, read some more, search some more.... there's pics, dynos, opinions, time slips, and more all a click away... and BTW 1,000,000 different opinions.... so take everything with a grain of salt.

^ too simple.... Only Unichip tuner shops can tune it, not as researched and played with in terms of different expandability options like the ZPI (Water to AIR IC, etc...), and priced higher... but, there are lots of pros to that style setup as well in terms of plug and play, big company and such...
(Thus the need to read up!) LoL...
Despite some ZPI customer's recent negative thread content, I'd say they also have a lot of satisfied customers as well (ScionDad, RetroDrive, and other respected and knowledgable SL users)
It's not a simple decision... and I repeat... full of opinions... research will get you the best info and will also show you any past threads about experiences both positive and negative to all the options.

Happy birthday zer0!!

Want some justification for choosing a 16G over the t3/t4 used by Turbonetics:
1) 16G is going to spool a whole heckuva lot faster than the t3/t4...enough said.
If you want to be amongst the fastest, then go with a quicker spooling turbo. Sure there is potential to put out more hp IN THE END, when you are trying to MAX the turbine. PSI for PSI, the Big Evo 16G that ZPI uses will out run a T3/T4 turbine used by the other competitors.
Want to know what a ZPI Stage 1 on 7/8 PSI of boost is capable of running in the 1/4 on Stock Scion tires, Stock engine? The fastest time of the day was 13.4 on Scion tires for the ZPI car @ 7/8 PSI

13.4 > 13.7. And if you look in Munch's vid, his front wheels are different than the rear. Wonder what kinda tires where on it

There use to be a F/I Comparison Thread. Don't know where it went too.
But there is no Apples-to-Apples comparison though.
TN is similar to Dezod in that they use the same turbines.
ZPI is the only company that uses the BIG Evo III 16G
GReddy uses the 18G, which is very similar to the 16G that ZPI uses.
Dezod - PnP harness, also their custom spec'd turbo on the S1 gives you the power you need and spools quick so you can have it streetable around town hitting 5psi by 2k rpms...
Worksmanship is top notch and they are super knowledgeable, friendly and provide amazing assistance when you have a question.

Nice excuse though.
Nice excuse though.
CFM is what matters. CFM.
Let's not start this debate AGAIN. All depends on the turbo, cfm rate, tune, turbine A/R......Too many variables to make a general assumption like that.
