Hi i'm new in here =)

I'm about to buy a Mazda RX7 Twin Turbo next Spring and i have some questions.

How many hp should i get with this modifications ?

4x1600cc Bosch Injectors
Apexi BNR GTR Fuel Pump
FX Fuel Regulator
Autronic SM2 Ignition/Fuel System
Turbonetics T60 Turbocharger + Single Turbo Manifold
Open Air Filter
Greddy FM 3-Row Intercooler Kit
3inch HKS Down Pipe
HKS Hiper Single Tip Exhaust System
High Flow Cat
Racing Beat M2 Clutch Kit

And is there anything i have to do inside the engine to get it not to brake with the new mods ? And is it any more parts i need ?

This is my first car with Rotor engine so i feel like a total newbie =)

 

it all depens on tunings

 

4 1600s on a T-60 ... why?

yeah ... HP will ultimately depend on tuning.

i'd say it would be better to set a horsepower goal first and then plan your parts and buildup based on that, rather that just throwing parts together and seeing what you can make out of it.
