Default i just put my new 2.5 motor in my 97 L..finally got everyhitng all set to go and turn

i just put my new 2.5 motor in my 97 L..finally got everyhitng all set to go and turn the key, and all i hear is the metal *KLANK* sound..the starter gear flying out and hitting the flywheel..
i went to Subaruparts.com and it seems that hte 2.2 and 2.5 had dif. flywheels, but the rest of the clutch system is the same parts..


if they are different, can i just put in a 2.5 starter?

can anyone help me out here?

Murray (adjusted clutch pedal..thats good now)

I'd measure the dimensions of the flywheels between the two. Changing to a stock 2.5 starter will probably still not work because of the location holes in your stock trans. One thing is for sure...you're giving me all types of things to check for when I finally get to do my swap. Thanks...(in a good way)!

I just got my flywheel/clutch replaced today, i asked about the compatibility between the older trannys and newer ones... The clutches are the same, but the older flywheels are very different, especially on how "deep" they sit in relation to the clutch.

Kostamojen...thanks for the info, im glad your dealership was able to share info unlike mine..


Storm.. i will make the necesary measurements tonight or tomorrow, when i get everything out..just PM me with what you need to know and i will do my best to get the pics.

i guess i will just pull the motor again and swap the flywheels..
i figure it will only take half the time since i just did this 2 days ago..

anyone need a MY99 RS flywheel or ECU?

Subaru designed it so you can use ANY EJ motor with any EJ tranny... As long as you use the matching Flywheel and Clutch... So you can use your tranny, but you need to use your flywheel. Pull the flywheel off your old motor, and slap it on this one.
I know what you mean about pulling motors, I've gotten mine down to 4-5hrs(including draining fluids) after pulling it 4 times... But for a flywheel, treat it as a clutch install, and you won't have to pull the motor.

you don't have to pull the trans out. Get the car on jackstands then act as if you are doing a clutch install... Thats how I've replaced Flywheels in the past. www.scoobymods.com www.northursalia.com Both those sites will tell you how to do the clutch install.
Hit me up on AIM if you need help...

flywheels are out..they do not appear much different..the only differences are where it wont matter, like where nothing touches anything(back of flywheel)
i will snap some pics, but im warning you, my camera sucks A$$.

either way, im gonna put my flywheel in the new motor with the new clutch.

seams odd to me.

I bought a clutch set-up from Paul Eklaund with his lightweight flywheel and as long as you have the same clutch set-up (push or pull) it's the same. I have the same clutch/flywheel set-up he sells for the RS in my 1997 OBS.. no issues at all. I would only fear that something else is wrong. What ECU are you using to run this engine? Are you sure it isn't turning over?

Thanks - Jon

i already swapped the flywheels and it starts up now..kinda weird, cause when i had em both out they look nearly identicle when next to each other.
both have same ring gear, both are the same size, same height, but the RS's was about 10 pounds heavier

my only problem now is getting it to idle correctly, i dont have the Idle air control solenoid hooked up..
since im runing the 2.2 ECU/harness, i cant hook the IAC up becuase they are a complete different type.
i hear some people use GM IAC valve's though, im gonna look into this and see what i can do.
otherwise im gonna have to fabricate a mount for the old IAC valve and get some custom tubing to go from it, to the new location.

I seem to recall Pleiades and Teague's Auto doing a clutch install on Pleiades' Legacy GTand having to use a 2.2 flywheel instead of the 2.5. They measured it before install and found it to be usable, plus it weighed a couple of pounds less. He never had any problems.

the flywheel was the original 1997 flywheel.

for some reason now the clutch wont fully disengage when i put the pedal to the floor..i wonder if hte 2.2 and 2.5(97 and 99) had differnet throw-out bearings.

the flywheels were nearly identicle, the only diffference i saw was the back where it mounts to the crank, the 2.2 was flat and hte 2.5 was raised a little, but when set next to each other, hte ring gear lies at the same height and all.

and from what i know the 2.2 and 2.5 used hte same exact clutch and pressure plate. i guess where they mount in the bell housing is a little differnet, becase my clutch will not fully disengage when the pedal is on the floor and hre cable is adjusted all the way in(to where the fork is barely touching the pressure plate)
im lost..
