August 24, 200520 yr Finally, the block and heads are in at the engine shop, getting a hone, surface grind etc. Then i just have to wait for my "special" NZ$60 head nut socket to arrive from Japan! List of things been done: New Bearings New Chrome rings re faced valves/seats re face heads Un clogged turbo water supply (now that might help...) valve guides/seals freshly painted rocker covers and turbo to throttle body pipe (the most important bit) and a whole lot of other new bits and pieces. Unfortunatly, i havn't got the money for new N/A pistons or for any balancing. Should go well when its done though, it also has an almost brand new turbo on it (thanks to previous owner), hopefully its still ok after running with no coolant for a couple of months.
August 26, 200520 yr geese man, you are really going all out. yeah, it took one hundred dollars (US) to win my head socket and valve tool on Ebay. that things gonna be sweet when you're done. you just going for all stock components or are there any mods happening down the road?? PICTURES!?! c'mon you can't just tease us like this...
August 26, 200520 yr Author Forgot to mention, reground cam as well. Ill take some pics once i start putting it together. Its all stock, for now anyway. It should be plenty peppy enough for what i want. I'll prabably chuck a water/air IC on it at some stage and up the boost a bit, but nothing extreme.

Seriously though, that's gonna be a sweet motor when it's finished.
September 12, 200520 yr Author Hi Ross, Did the parts you brought from me come in handy? Hayden Yeah, although not as much as I had planned...... I had measured my crankshaft with a hired out micrometer, and found it was below the spec for .25 undersize - thats the main reason i wanted your engine. When I borrowed a mic from a mates workshop, i found that mine was within spec for the .25 undersize after all!!! I'm still using the crank from your engine, as the journals look smoother, also i'm using your intake manifold (cleaner!), injectors (no broken caps!) and valve springs. Plus now i've got heaps of spares for it.
September 12, 200520 yr Wow, its great to see someone else messing around with EA81Ts. More power to ya! Let us know how the assembly goes.
September 12, 200520 yr ross ,good luck i just bought 2 ea81t going to have some fun rebuilting them this winter!!!!!! ps more pics more pic please
September 12, 200520 yr Looks great Ross, l too am going the ea-81t route with my brumby and am close to fire up stage having done most of the hard work, thankfully my motor didn't need rebuilding but it's still a mission converting a standard car from n/a to turbo, not to mention expensive, esp. in Australia, so good luck with your project, the pictures look very impressive.

September 13, 200520 yr Author ross what year car did your motor come out of mine 2 are 1984 Mine is an '83.
September 28, 200520 yr Author Grr, another set back. Just been checking ring to groove clearences (which are fine), and noticed some scratches in the lower faces of the grooves!! Cant believe the engine shop, that apparently machined the grooves, didn't notice! Looks like i may need new pistons after all, oh well, maybe ill get some N/A ones!
November 12, 200520 yr Author Update: Engines been on the back-burner, had exams at uni. Starting to get back into it, and decided that now that i have money (job over uni holidays) i may as well get my crankshaft reground (apparently you can go below -0.25mm, contrary to what the fsm says) and get some new lifters. At least that way i know everything is sweet as. So, that puts the spending up to around, hmm....NZ$800-$1000. thats US$600-750 or so. Not bad.
November 13, 200520 yr Man I really love the pics of your motor.How much boost you planning on cranking into it after its broken in?Looks like it will run like a top.I am currently getting parts for my ea81 motor I a piecing together.Gives me some inspiration.I am also curious to see what type of special socket you are refering to.
November 13, 200520 yr I heard mine sputter a few days ago (ea81T) but I have a fuel pump wiring circuit that wont power the pump to fix.
November 13, 200520 yr Author whats the special socket look like and what size is it? Its just the one for doing up the head nuts under the rocker shaft. Its a 17mm 1/2" drive. As for how much boost i'm going to run, well i'm not sure. Probably 10psi or thereabouts, i'm not looking to turn it into a racing car! Just some extra power for the mountains will be good.
January 22, 200620 yr Author Finally getting it done, old engine is out, new is assembled minus turbo, intake manifold and accesories, should be going in tomorrow or the next day. heres a pic of it on the bench the other day: http://www.ultimatesubaru.org/photos/showphoto.php?photo=9760&sort=1&cat=500&page=1
January 22, 200620 yr Finally, the block and heads are in at the engine shop, getting a hone, surface grind etc. Then i just have to wait for my "special" NZ$60 head nut socket to arrive from Japan! I was able to shorten a 6 point 17 mm socket by grinding it until it would fit under the rocker arm shaft. It was a tedious process but it worked.
January 22, 200620 yr I was able to shorten a 6 point 17 mm socket by grinding it until it would fit under the rocker arm shaft. It was a tedious process but it worked. that sounds like something I would do Ross - that engine look beautiful - given the level of care you are taking in your rebuild, I am sure it will perform at least as well as it looks when you are done good luck
February 1, 200620 yr Author Got around to getting motor in today, just got to hook up a few fuel lines, put the radiator in and fix a stripped thread for a turbo coolant line tomorrow - should be all go then......
February 2, 200620 yr Author Its Alive!!.............Barely..... Runs rough, wont idle by itself and plugs are black after 5 or 10 mins of running. Didn't have my timing light with me, i suspect maybe the disty is off a tooth - gonna go re torque the heads now then see what i can find...
