ea 81 engine overhaul

yes, like he said.   Felpro Permatorque for HG and Subaru OEM for all else.  Especially for intake and valve covers.

  Depending on the condition of the current Hitachi carb and associated 1000 vacuum lines.... I would definitely install a Weber... at the very least.

How's the clutch disc, pressure plate?    Always install a new pilot and throwout bearing.  They're cheap.

  Rebuild the oil pump.   New contacts in starter.  New hoses and belts (keep old for emergency spares).   Plugs, wires, cap/rotor.  New water pump and thermostat.

I order "stone" brand headsets through WorldPac.  They always come with Japanese OE headgaskets and ussually always good NOK japanese seals.....sometimes the seals are THO but the headgasekts are always OE.

 

Sometimes same sets listed as Ishino.  Same deal.

 

I personally would not use FelPro.

 

Japanese made only for me.  My $.02

 

Oh yeah....I would not ditch the hitachi carb unless there is has excessive throttle play.  Otherwise, Hitachis are easy to clean out and reseal and will run GREAT if properly working, which ussually just requires a $25 carb kit and clean out and reseal.

     As far as gaskets you should be able to order for an '83-'84 and the gaskets should be the same for pretty much any year. I have found over theyears that ea81's are not a sensitive as the others to which head gasket you use but hate aftermarket intake gaskets. NO the ea81 and ea82 heads are not the same!

I used ITM ( I think that's right ) for all my parts and gaskets but order intake and exhaust from Subaru. I order from a place called Rockerarm supply in Spokane but it is also available on ebay but like I said the ea81 doesn't seem very sensitive to aftermarket rebuild parts. I have several running around here that I have done in the past.

I found this link and shop the other day. The owner, Ron seems like a decent guy. I enquired about the kit and his responce was:

 

"The part number and price for the engine rebuild kit is SU1781LEK $288.94 plus $16.80 shipping to a U.S. street address.

This kit includes: ITM pistons, wrist pins and rings, Clevite main bearings and rod bearings, ITM complete gasket set, and ITM wrist pin bushings.

The oil pump is no longer available.

Topline is the manufacturer of the re-ring kit and all parts are Topline EKSU6R $267.25 (1.2mm top ring width).

This kit includea: premium rings, main bearings, rod bearings and complete gasket st including Viton valve seals.
 

Of course, we will need to know the size of the pistons and bearings. The pistons come in std. (or .020" over sizes) and the bearings come in std. (or .010" or .020" or .030" over sizes), all the same price."

 

Is anyone familar with some of these part brands?
