I would really steer away from them, don't own one but had to tune it and it just can't be properly tuned. I had to get it to the best aproximate safe tune.

- The turbos are tiny, tiny (twins) I would not expect upgradibility with such small things.
- The lag is just unbeliavable, this is my first time that I've ever had to do such long runs in the dyno so they could spool (dynapack dyno that you could apply 100% load as different than others), I even had to do the runs three times so the system would got to a level of temperature so the turbos would actually work.
- This is the lone FI car that when at WOT you would still measure vacuum for some time down low.
- To get it to a decent power level we had to replace the WG spring so it would make 8psi and get us into the 4xxTQ/HP range.
- They use quality stuff in their WG and BOV (Tial rebranded as STS) (or at least that is what it looked like)
- So they could get a CARB number they went thru the most incredibly complicated PCV control system that is a mess of wire and hoses in the engine bay. (A hobbs switch controlled purge valve to the intake)
- Everything sits pretty low, specially the piping that goes below the transaxle.

I would really look elsewhere for a turbo kit.
