Hello everyone - I am a new member today. I have an My07 Liberty Sti tuned Wagon 6sp with an MRT XB kit (3 inch turbo back exhaust and EcuTek with custom tune). I am currently running ATW 169KW and 5100N drive force on STI Melbourne dyno. Started out with Vin reflashing my ECU and getting me from 128KW to 140KW ATW and around 3600N drive force. I had come from owning v8's and initially it appeared slugish. A lot better after Vin looked at it initially mainly on torque.
I want the next stage of power improvements and have been looking around at power kits. I have talked to MRT, HPF, AVO, and a couple of other and basically they tell me (Upgrade - turbo, TMIC, Cold air intake, Inlet pipe, fuel pump upgrade, some say injectors) and I will make around 200 - 205KW ATW dyno dynamics dyno. Incidently converting drive force to torque I found that roughly dividing by 14.1 brings you close (derived from websites giving both figures - seemed fairly consistent). Does anyone have an actual conversion reference.
I am interested in getting an understanding of where you finally ended up on these mods and talking to you directly. If you are able to text your phone number to my mobile 0408939874 I would appreciate any time you can give me.
I have been told that the piston and conrods are a limitation on our EJ255 engines but am interested to here what others have heard. Basically it is very difficult to identify what the differences are between EJ257 (Imp STI engine), and changes to the EJ255 (liberty versus WRX motor) Is this listed anywhere on the website?
