I've only done a limited amount of research on the dual mass vs. single mass flywheel situation. The research I have done leads me to believe all the flywheels I have are dual mass. Of course I'm not home to do an ocular inspection. MY super brief research suggests that the 02-05 WRX flywheels are dual mass and they switched to single in 2006. Beyond that I have no idea. If the information I have is accurate I would have to source a single mass flywheel regardless, that I'm sure would need to be resurfaced. That just opens up the vortex of aftermarket flywheels which I'm on the fence about.

Repaired the pictures that were broken in post #3 of the heads. Also had a moment of concern when I realized that the 2008+ STi gaskets (11044aa770) are different than the 04-07 STi gaskets (11044aa642). Now I have concerns about my later block (which I believe are all the same) and my heads. I'm 99.9% positive I used the earlier -642 gaskets when I assembled the long block. However I'm not positive what year my SOHC heads are from.

Can anyone tell me if the coolant passages of my heads match the coolant passages of the earlier 251s? Photos below for comparison.

04 vs 08 Headgaskets:



My Heads - Note the 08 style upper coolant passages:

Was there a thickness change as well? Have you checked?

I haven't personally checked. I did a bunch of research on the subject the other night and didn't notice any mention of a change in thickness between the two, although that wasn't really the information I was after.

Thanks dude. I try to post anything I end up having to spend a bunch of time researching. There should be some more progress in the next few weeks. Trying to get the car started by February 16th.

Another thing on my list is figuring out my PCV system. I'm pretty much decided on running dual catch cans. Right now I'm leaning towards the Mishimoto compact baffled catch cans. ( Amazon.com: Mishimoto MMBCC-MSTHR-BK Black Compact Baffled 3-Port Oil Catch Can: Automotive )

I'm going to run one from the valve cover breathers, potentially with a filter to outside air or into the inlet. The second would be run from the crankcase vents to the PCV valve/Intake manifold.

Question I have been pondering is whether it's even necessary to route either line back to the inlet tract or Intake manifold. The only reason to utilize the PCV valve that I have found is so intake vacuum will help to scavenge air from the crank case. Thus I should be able to route the crankcase vent directly to the PCV valve and not connect it to the rest of the intake tract at all. Incoming fresh air could be pulled through the Valve cover ports which will either be connected to the inlet or the directly filtered underhood air. I'm not concerned with metered air issues as I am running a MAP based engine management system.

This is essentially what I am proposing.


Utilizing these parts. The reason for the 3 ports (2 in / 1 out) is that there's a port on each valve cover and there's also two ports on the crankcase. Also the 3 port units are cheaper than the 2 port ones!



Any thoughts?



Is there something that I am missing?

So I've decided on the Southbend Stage 2 clutch with a Fidanza flywheel. I picked up the flywheel from a member here who said the Pilot bearing was loose. Some quick research pulled up this.



I priced the Gap Filler Loc-Tite (#660) and a very small tube will be ~$14 to my door. Has anyone installed an aluminum flywheel and gone through this process before? Just want to make sure I get the right stuff and don't end up paying $14 for 6ml of something when I could pay $14 and get 50ml of something else for the same task.

****EDIT 04/06/16 - When I installed the pilot bearing it fit in the race perfectly. So I ended up not using the $10 bottle of loc-tite I bought.*****

So you're planning to loc-tite the outer race of the pilot bearing to the flywheel?
