EJ25 into BRAT

Recommended Posts

I'm looking at a EJ25 out of a 2005 outback on craigslist. The motor needs new valves above cylinder 3. Since the engine doesn't come with the whole wiring harness for the car what can I do to get the wiring in the BRAT? also before I get too ahead of myself, will a 2005 EJ25 even fit in a BRAT? I'm looking to buy the transmission plate adapter and use the 4-speed in the BRAT until I decide where the car is going to go. Its a EA81 BRAT by the way.

 

Thank you

SJ

I don't think a 2.5 will fit between the framerails of the brat.

 

A 2.2 barely fits, and those have smaller heads.

 

It it will also eat the 4-speed trans for lunch.

 

I would recommend a 2.2 swap rather than a 2.5

 

2005 is a hard year to convert to also....Electronic throttle body and integrated ABS computer and a few other things make running that engine standalone tough. Unless you use older managment or aftermarket.

Since the 2.5l already needs head work, you could put used Phase 1 2.2l heads on it and it would fit in the Brat without having to mod the frame rails. Use a 97-99 Legacy Outback or GT or a 98 forester wiring harness and ECU to run it. Heads and intake manifold off a 95-98 2.2l from an auto trans Legacy or Impreza.

i run a 2.5 twin cam turbo in my 79 wagon gen 2 is the same body rails i had to porta power the rails flat to fitt but it fitts No to the 4 speed put a 5 speed in it. And find a older ej engine they are simpler and have no vvt and can be run off a older harness 89-97 wire harness seem to work best. The 2.51 single cam engine will fitt to but wireing is mutch harder on theese

The phase 2 single cam 2.2 and 2.5 engines can be run using the earlier management.....just have to adapt the older harness to fit the new manifold and use the older style Crank/Cam wheels and the older throttle body.  IAC is an issue, but once warmed up makes no effect.
