I measured my pistons and bores:
bores..... 1 top 3.81** & 3.81** 1 bottom 8.81** 3 top 3.81** & 3.81*** 3 bottom 3.81** 5 top 3.81*** & 3.81** 5 bottom 3.81** 2 top 3.81** & b3.81** 2 bottom 3.81** 4 top 3.81** & 3.81*** 4 bottom 3.81** 6 top 3.81** & 3.81** 6 bottom 3.81** pistons are all 3.81** to 3.81** doing the math the side wall clearances are: 1 .00** 3 .00** 5 .00** 2 .00** 4 .00** 6 .00**

My heads, pistons, and valves are officially on their way for coating. Fedex picked them up today.

I've gotten some .50mm oversized high silicon aluminum main bearings coated which are on their way back to me now. I'm waiting on them so I can cage them and get the measurements to have the crank shop machine the crank to.
They are in the process of coating the pistons, heads, and valves now. I'm sure I'll end up waiting on the crank. |

bearings are here. I'll cage them tomorrow and send my crank out to be redone on monday.

I caged the new bearings.
Journal# bearing bore oil clearance journal size 1: 2.34*** .00** 2.34** 2: 2.34*** .00** 2.34** 3: 2.34*** .00** 2.34** 4: 2.34*** .00** 2.34** 5: 2.34*** .00** 2.34** 6: 2.34*** .00** 2.34** 7: 2.34*** .00** 2.34** Now I can send the crank back to get straightened and ground to journal sizes I'm specifying based on caged bearing measurements.

fedex says my crank was delivered to the machine shop today. Hopefully they get right on it.

I'm dropping the heads and valve train parts off for the valve job, assembly and final cleaning. I took some pictures of the coated parts while they are still seperate parts.

Long,
The valve job you are doing. Would this be similar to what DPR racing does for the Honda engines? What they call it...a 5 angle valve job. I remember reading up on that years ago in magazines like Sport Compact Car. Was a big thing then for naturally aspirated engines. It was done so air could travel past the valves smoothly without the corners of the ports hindering the flow. Made a big difference on their flow bench. I went on their site last week and found they did some cylinder head work for Subarus. Probably the Impreza mostly. Poked around the site due to some ideas. Looking forward to seeing how this build goes.

no, it will be a redux of the factory valve job.

Are these the oil clearances you are specifying or are they the clearances you measured, and you are shooting for more clearance?

those are the journal sizes I am specifying to obtain those clearances. As I said I measured the caged bearing bores..then subtracted the clearances...which yielded to sizes to grind the journals to.
I guess you are thinking they are tight. I am using coated bearings. If you ignore the coating my oil clearances are 4 tens larger than the #'s I listed. Think of my clearances as being 20 tens for the bearing with the thrust flanges and 16 tens for the rest. |

That's a lot more clearance than I'm going with. According to the Subaru specs that's way past the wear limits but with the tri-metal bearings you are using you definitely need to error on the loose side. I wouldn't go that loose obviously but then I wouldn't use the bearings you are using either. You'll just have to figure it out.
