EJ207

[Fotis]

Hello everyone, i will be tuning a stock EJ207 spec c V8 subaru sti. 

RON 98

VF37 turbo 

My question is does anyone here know the limit of the stock internals (max power and max torque) ? 

Thanks in Advance

With a bad tuner, they can be destroyed at less than standard power.

 

With a good tuner they can easily support more than a VF37 will make.

Bad tuner with the meaning of what? 

So lets say maximum 450hp at the engine?

Quite simple, bad tuning can destroy even the best engine in a matter of seconds.

you will have no problem maxing out the VF37 with the stock engine, it can take that turbo no problem with a proper tune.

So how much hp is the vf37 maxing out?

I have read somewhere 400-430hp (engine)

On petrol it will be in the range of 190-220kw atw depending on how hard you push it
