Non-STI 2.5 swap vs. 2.0 swap?
I'm looking to swap down the road and I want to formulate a game plan sooner rather than later. It's best to think everything through especially since this will continue to be my daily driver. I'm in love with the idea of staying with a bigger displacement motor rather than go for the 2.0. I love the off the line torque and the way it can dawdle around town without much effort. I'm not looking to go with a hardcore 450+HP setup, so I'm not necessarily gunning for an STI swap since they're not at all cheap. Are there any different considerations when looking at the 2.5 turbo motors from the FXT/Baja GT/Legacy GT? Would finding a wrecked FXT bode better since it's essentially an Impreza underneath or is just about everything the same between the three cars?
I know the motor will have no trouble fitting, but I want to be sure I have my subframe, accessories and front suspension details all down pat. So what do you think, am I making this a bigger headache by not just finding a wrecked and plentiful 02-05 WRX? I'm pretty hellbent on a 2.5, but don't want to dish out STI cake. EDIT - sorry, I think I should have posted this under Subaru Conversions. If a mod reads this, could you please move it to the appropriate section? My apologies.

Food for thought: Legacy GT short block part number is the same as STI short block part number.

you can build a very stout motor thats 2.5l of fury without going sti, like broken_impreza_guy said the legacy GT block might be a good start.

And I think finding a wrecked LGT shouldn't prove to be impossible. I like that idea. I've also heard the front subframe from one is much better for completing a GC swap.
Is going from DBC to DBW a big deal on a GC? Or will the wiring harness merge + new ECU take care of all of that? Again, weighing out the differences between an 04+ 2.5 and an earlier EJ20 swap. |

going full STi Ej257 with AVCS= need DBW and a FULL HARNESS from headlight to taillight.
Full Ej257 with WRX intake/ecu etc= less work, dont need dbw and idk how much of the sti harness you need. 2.5L shortblock with WRX heads/intake= easiest and starting to be the most common. any i see FS has a 2.5 now over a rebuilt 2.0. i went with the whole shebang with a full EJ257 with AVCS. lots of work, but was so worth it. note this was all based on my research for a 03 WRX. (btw i have my old WRX **** for sale shoot me a pm if you need a block/wiring harness/ecu etc) |
