2.5 Swap??

[rally2.5rs]

does anyone have information or know how to do a 2.5 swap from a newer legacy? I need to run n/a for my class and 2.5 is the max displacement. thanks!

The easiest way I can think of is this http://www.pms.net.au/03_enginekits.htm#Litre25

Granted it is not the most cost effective, but it may be the easiest.

the EJ25D dohc will bolt right in, use your sensors if any of the plugs are different. the 2.2 computer will run it, just not at the optimal level.

awesome! thanx!

There's a post on the Ultimatesubaru.org/forum site for a 2.5 swap HERE....also done for a rally car, I believe.

That USMB post is awesome thanks wtdash!! Anyone tried the 1.8 TB? I would prefer the IAC up there anyway much more room.

outline of the process i went through

22T5mt items swapped onto phase 1 EJ25D engine
-
pwer steering pump
alternator
MAF
flywheel cover plate - under-side
-
22T5mt manifold items swapped onto EJ25D engine
-
22t throttle body w\c position sensor
22t idle air control valve
22t ignitor
22t purge control solenoid
-
22T5mt harness modification includes :
-
extending engine coolant temperature sensor clip to opposite side } on coolant crossover
-
extending temperature sensor clip to opposite side } on coolant crossover
-
knock sensor : switching connector style to EJ25D type, to accomidate the knock sensor on 25D
-
22t crank sensor : switching connector to EJ22t style to accomidate 22t harness
-
22t cam sensor : switching cam sensor to EJ22t style to accomidate 22t harness
-
neutral items \ universal fit both harness
-
injectors 1 2 3 4
oil pressure switch
engine coolant temperature sensor : needs harness extention
temperature sensor : needs harness extention
-
EJ25D engine items remain
-
knock sensor
crank sensor
-
EJ25D intake manifold items remain
-
injectors 1 2 3 4
vaccume \ Intake tubing
-
OTHER PARTS NEEDED TO SWITCH TO EJ25 > 5mt
***
5mt intake hoses
***
UN USED PARTS AND SENSORS ON EJ25D > auto
***
Tourque convertor
EGR valve - i created a false valve gasket and bolted the EGR Valve back on over-top the false gasket with a high temp gasket sealer + capped plumbing
EGR valve solenoid removed + capped plumbing
-
