so ive been driving and building subarus for quite a while, but id like to get some feedback here

 

i have my beloved 1991 legacy, its been with me for almost a decade and is nearing 400k.

i intend on keeping her forever

it has a 3.5 inch lift, and 215/75/16 tires, quite a bit larger then oem.

 

still has 4.11 gears and stock ej22 for the most part

 

i use the car daily to commute to work, stop and go traffic, occasional woods wandering, 4 wheeling, and so on, but pretty mild

 

so- as for modifying the clutch and flywheel, there are two schools of thought- light weight flywheeel, such as an exedy or similar

or find a slightly heavier flywheel like in an ej25, these mods can be accompanied by heavier or lighter crank pullys as well

 

light= spin up quick and decelerate quick

heavier= rotational mass, lugs better

 

what do fellow tinkerers have experience with?

 

also my clutch (napa brand) sucks donkey rump roast royally. i need to replace it with a quality one, recommendations?

the car still is very close to stock HP wise

 

cheers yall

Driving lifted rig with big tires will SUCK with a lightweight flywheel.

The flywheel maintains rotational momentum of the engine when engaging the clutch to start rolling. A light weight flywheel doesn't keep the same momentum, which means you have to use more throttle, and you have to ride the clutch more in order to keep from stalling the engine. Its bad enough with stock sized tires, bigger tires will worsen the effect since you're trying to get more weight rolling using less momentum.

 

If anything, heavier flywheel will be better, but if you have no trouble with your current setup, I wouldn't change it. If you have problems with the clutch slipping, a 2.5 clutch kit may help since the 2.5 pressure plate hasa higher clamping force.

agreed. never tried the light weight route, but as with anything, " on paper" and " real world" are vastly different sometimes

 

i ordered a severe duty ej25 clutch, and a  new oem ej25 flywheel, should be approx 6 lbs heavier then stock. will accompany with a sohc 2.5 crank pulley and thump away!

id love 444s in the car...but admittedly it will never happen
