Ok now according to Vishnu the Stage 2 kit puts up mid-high 12's in the 1/4 mile and is pushing 340-350 hp. This kit comes with:
Vishnu Re-mapped ECU
Main Power Pulley
Up-pipe
Turbo back exhaust
New Turbo
And bigger injectors

So my question is if I bought the Vishnu Re-mapped ECU and used other quality products in place of the Vishnu parts would I be able to achieve the same HP and 1/4 mile times? Also what turbo does Vishnu use in their Stage 2 kit? Thanks for your help guys.

 

The stage II package includes a VF30 turbo from IHI. You can choose to use other components, but if they vary from our products it would require custom tuning to make as much as even our off-the-shelf stage II maps make with our kit. Custom tuned full Vishnu setups often have a little power left behind as a safety margin due to individual engine variances.

 

Well all I really wanna do is use all the Vishnu parts but I want to have an Apex'i GT spec catback exhaust is that possible instead of the Vishnu cat back?

 

Isn't vishnu's a turbo-back with stage 2? Still waiting for mine to come in (6 days and a wakeup).
