Hello everyone - I am a new member and interested in feedback on stage 3 mods and outcomes others have been able to achieve.

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 (dyno dynamics roller dyno). I 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 end after stage 3 mods for anyone that has completed this previously.

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?

Welcome

With the right parts and more importantly a good tuner, you can safely get 240-250 kW atw before having to open the engine.

Speak to a member on here called Phat GT, he has the knowledge and experience to help with these sort of mods.

Thanks Tony - will do.

Interesting the different feedback you get from many of the suppliers with relation to turbo types.

Lol…… many of them will push what ever crap they have in stock.

I interested to know what MRT advised you to fit?

Yeah - very difficult to get a turbo spec from them, however I am told they are looking at upgrading the kit with an alternative type and should hear back in April. They want me to fit, new turbo, TMIC, new fuel pump, not sure on injectors and retune. I have seen an XC kit fitted when my XB kit was done. Not all that much difference between mine and the XC kit at that one around 19KW and about 30Nm torque. I wasn't that happy to commit to nearly double what I was paying forthis little gain. Not sure this fellow got a good result. I am however interested in what they get with a better turbo.
