"What type of oil pressures are you seeing with the er27 pump vs the ea82 pump?" It's been a while since I had the analog dash in the car, it's digital now. From memory I think hot idle was about 1/3 of the gauge. I'll dig up some pictures when I get time of what's involved in getting the pump to 'fit' Unfortunately the drive shaft is different so a custom oil pump pulley needs to be made and the plastic timing belt case needs to be altered because the bottom of the pump is a little different in shape. The same goes for the water pump, the casting is a little bit different in shape and also requires some timing cover mods.(done by plastic welding the cases) The biggest 'issue' with the water pump is that the bypass pipe comes off at a completely different angle and requires some interesting plumbing. Obviously it's harder over here because we didn't have the ER27 in our market so it's hard to get parts to try, but if someone had an ER27 next to an EA82 it would be worth trying to fit all the timing gear (cam pulleys, tensioners, idlers, cases, belts) from the ER27 to the EA82 block, I reckon if that were possible the swapping of the oil and water pumps would be almost 'bolt on' If that does work, someone better save me a full set of ER27 cases and timing gear

Yes I have an ER27 oil pump on my EA82, as well as the ER27 water pump. Works well, oil light goes out while cranking. It's not impossible, but there is enough differences in the timing belt setup between the two that the swap is 'interesting' They both physically 'bolt on' to the block. Would I bother to use ER27 pumps on my next EA82? Probably not.

I'm guessing you meant 'two nuts' in the HLA body which the adjusters screwed into?

Found this for Chrysler motors : http://www.allpar.com/mopar/22-chronology.html This for vauxhalls : http://workshop-manuals.com/vauxhall/corsa-d/j__engine_and_engine_aggregates/dohc_diesel_engine/cylinder_head/hydraulic_valve_lifter/repair_instructions/replace_all_tappets_hydraulic_valve_lifter/

I like that retainer! Will that fit in the cam box? What engine are they and the lifters from?

Roller rockers sound interesting! Can't wait to see the lash adjusters and gaskets...

You get the gaskets yet?

I don't expect they make them in solid form, but the HLA's in GM SOHC c14NZ or C12NZ 4 cyl enignes out of Opel Corsa's, Holden Barina's, Daewoo 'whatevers' are very similar to our EA / ER ones... I heard someone used Datsun adjustable ones in an EA82 once, but I couldn't find many details, allegedly they were OE in one of the old Datsun engine, like the L20 or something... I have often wanted to get some custom pistons made up with the gudgeon pin .040" higher and get the bigend journals .040" offset ground undersize (more if smaller bearings than .040" were available) to increase the stroke a little... Bore it out a little too and get the old gal close to a 1.9

A lot of work adjusting those and test fitting the cam box on and off to get them right, but the results would be interesting! I wonder how similar in size those are - perhaps they could be turned down or presses in a sleeve to suit of EA's...

Just wondering why you didn't just get custom forged EA82t pistons from wiseco?

Maybe try these guys http://www.argorace.com.au And these guys, I think they have done ea82s before from memory... www.rpw.com.au

this may help point you in the right direction : http://www.subaruxt.com/forum/viewtopic.php?f=1&t=12263&st=0&sk=t&sd=a&hilit=race+build#p138384

Maybe you could just buy some stainless threaded rod and cut to length? Or you could try http://headbolts.com/ they may help you match something up, being a third party...

That doesn't sound weird at all aye, that's what I meaned about the 'blocked off' ports on the top, outside of the cylinders, the only thing I could think of is that MAYBE it is to promote a lower block flow bias. Some work can be done to the water inlet port, behind the water pump too, get stuck into that with the die grinder!

I've always wondered why the outer, top coolant jackets are restricted by the gasket, do you think it's to promote more coolant flow to the exhaust side of the head? Also puzzled me why they block off the large triangle port between the cylinders in the block, the head could be drilled to match up with that aswell...

By the way, what changes are you proposing?

Yeah, sounds like a plan.

Did you mention the quote I got from him, in the post a few posts up from here? Perhaps we could discuss this via PM?

Does anyone have an intact OE gasket they could send this guy so we can get the ball rolling and get a part number for these EA82 or even ER27 gaskets...

You gonna grab a set? I suppose we should send him an OE sample first...

Its difficult to read the translated japanese, but are these EJ20 pistons in an EA82 block? http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&eotf=1&u=http%3A%2F%2Fwww.ptrlabs.com%2Fxt6%2Fsyoukaku-home%2FFLAT6-turbo01.htm Got the reply back about the MLS gaskets: "Hi, Thanks. Cost for those in a pair as MLS gaksets 1.5-1.6mm thick would be $134.95 each. Cost to ship a pair via registered airmail would be $14.95. Lead time right now is 2-3 weeks. If you decide to place an order just let me know and I will send you a PayPal invoice you can use to pay by credit card." I asked about a bulk order, if they were stainless or mild, different thicknesses and whether a sample would be required; "Those are made from a coated stainless spring steel just like Cometic or other MLS head gaskets. If you were to order 10 or more I could offer them for $129.95/ea. We can make any thickness, but price will vary with thickness. I think it would be best to have a sample (can be returned if you want-new or used) to be safe. You can find info on shipping items to me at www.gasketstogo.com/mailing.htm" I reckon that's pretty good pricing and lead times aye!

Anything ever happen with this?

I just sent the details through so it will be interesting to get a reply. So no one knows of a 'ea82 head on ea81 block' thread? It sounds like a myth, may well be, but I'm interested to find out...

Here is the reply, received on Sunday, not bad! "Thank you for contacting me. It is quite possible we have, although they may not have been identified as such as I don't see them in my records, which are admittedly not the best! Do you know the name of the person who ordered those? In any case, if you can send me an image of the gasket along with L x W dimension, thickness, and quantity I can let you know what it would cost to make for you. Regards, John" Is it okay if I send the above photo and some measurements? You don't happen to know the OE compressed thickness do you?

It would be interesting to see the finished quality of a Thai reproduction... I've sent them an email. Did they give you a quote? On another topic, I read a post last night that someone was modifying EA82 heads to fit an EA81, does that ring a bell with anyone? I couldn't find any topics about it...
