Bleeding cooling system on Ej22 swap ea81 turbo car
Legacy777 replied to ShawnW's topic in Subaru Retrofitting
How is the ea81 radiator setup in comparison to the ej22? Without that bleeder screw on the ej22 radiator, it'd be very tough to get all the air out. Can you tilt the radiator at all? -
Just want to comment on the brake balance thing since I went through a lot of stuff on my car. The newer gen subies use a diagonal circuit brake system, and I would venture to say the older gen may use a similar setup to help maintain some amount of braking in the event of a failure. The problem with this is, fitting an aftermarket adj. proportioning valve is pretty much futal unless you replumb all the lines, and/or sacrafice the safety of the dual circuit design. I will caution about upgrading only the front brakes without doing something in the rear. The car will dive severely under hard/panic braking. I had this very problem along with some others when I upgraded to WRX front brakes. I got in a panic situation, the fronts locked up much sooner then I was used to compared to the old brakes and I hit the guy in front of me. There's so much you can learn about braking and tweaking this stuff, but from what I've found, the best balance is about a 10% shift rearward in brake torque compared to the original factory setup. This is mainly because the factory adds a little bit of front bias because your normal driver reacts better to plowing forward in a turn vs. the rear end coming around. Here is a spreadsheet I have created with various newer gen brake caliper & rotor information. It can be used to calculate the changes in brake torque when swapping calipers & rotors. There is a brake torque calculator with drop down menus on one of the tabs. The formulas are pretty straight forward so you could create your own sheet if you have information on the older gen brakes. The main things you need for the calculation are: Outer disc diameter Effective disc diameter Caliper piston diameter Here's the spreadsheet http://www.main.experiencetherave.com:8080/subaru/techinfo/brakemath.xls Josh

There are various things to upgrade. However there may not be much specifically listed for your model.....most of the pre 02 impreza stuff will fit. I'd recommend KYB struts. There's a tranny cocktail one of the guys on http://forums.nasioc.com/forums has come up with. Check out the trans forum and search for uncle scotty's cocktail. I've been really happy with the shifting results. You should be able to put a short shifter in your car, if not, you can swap over to the new style linkage and then be able to run a short shifter. I'd personally recommend just replacing the front and rear linkage bushings with poly bushings. You can get them from www.kartboy.com Others should chime in as well. Welcome to the subie clan Josh

Adjust TCU?

The thing though is that this is an automatic. At full throttle you get torque multiplication through the torque converter , so the car still is going to pull all the way to redline. I know that's the one thing I miss about my automatic when compared to the MT. -
What sealant?
Legacy777 replied to samm's topic in 1990 to Present Legacy, Impreza, Outback, Forester, Baja, WRX&WrxSTI, SVX
Use the Ultra Grey. Personally, I'd pull the trans. The motor has a lot more stuff to reconnect. Also, for future sealant reference. http://www.main.experiencetherave.com:8080/subaru/techinfo/subaru_sealants.gif
