S14 with FORD XR6 engine +T......

We see many engine conversion these days. Today we had a S14 with Ford XR6NA engine(only NZ$400 second hand) with twin turbo set up. According to  SOMEBODY...this engine can stand over 400kw at wheel??!!!(it wasn't true!! The turbo engine will be, but not NA engine!)

Once we started tune, this engine was making good power....till some point. At 13psi, it made over 400kw at wheel(over 540hp at wheel). This was good enough for only $400 engine, but someone wanted try 15psi......(*_*)"""

AND this is the consequences......

                                            We found after that NA Barra engine has very weak conrod,
                                            And according to expert, 300kw at wheel, and 6psi is the safe
                                             zone, The turbo engine may hold over 400kw at wheel. We need to have a reliable information!!
