well, im bored, so here is a complete spec list and stages of build of my truck
so here it is taking shape now, my truck, finally getting some power!
started off as a standard EA81, single hitachi carb power truck, found on ebay UK in mint condition, which has now changed drastically over the past two years, and yet to change more yet!
here is how its been for the last year odd, with a few small alterations here and there after this piccy was taken
the love of old skool rally cars and AE86 and the like drift cars and the like, inspired me to modify the thing that i love, and all i have ever wanted, i love imprezas and all that, but i have fallen big time for the EA's in the last few years! hence the changes!
so after a spec list including:
-subaru 'lowbar' rollbar
-2 maxtel 100W lights
-4 55W fog/driving lights
-Custom made tonnou cover
-Cherry bomb 3" straight through back box
-Facet competition fuel pump
-K&N style breather filters
-high voltage coil
-armtech electronic rev limiter
-52mm tachometer
-52mm oil pressure guage (both in a pillar mount)
-rally flaps
-K&N air filter
-A bar instead of bullbar
-3rd brake light
-weller style, white 8 spoke 16x6 rims, running yoky 205/45/16s
-sparco sprint 5 buckets
-lowered 40mm all round
-sparco rally steering wheel
-bumper bumpettes removed
-tinted rear lights and indicators
-sub woofer and some decent components
its turned out as it is now
after much buggering around with front driveshafts, i gave in, and now run RWD perminently, and this is how its gonna stay! hence the want to make it a more performanced based truck
then came the time for some power
the new long block
the parts altogether, which include SUB 4 dualport heads (ready to go off and be machined) and the matched weber IDF 40's
no more engine! lol
all the parts again
the old engine!
the underneath, with the crossmember alteration to fit the extra exhaust due to the dual ports rear port location (not finished, just a basic shape)
all in all, the engine has
-highlift custom cam from SUB4
-Dual port heads, skimmed for compression uprate
-Twin 40 IDF webers with custom inlet manifolds
-4 branch custom stainless exhuast manifold and alterted crossmember
-high quality bearings, seals, rings all renewed throughout with a brand new old pump
-lightend and rebalanced flywheel
-SUB 4 water circulatory system
more to come so damn soon! including front spillter, adjustable shocks and coilover conversion within the next few weeks!
-
wow, thats a well smart lookin engine, i like lol, looks like you got all the bits nicely as well, the EJ route seems easier than ever now, most of the parts are off the shelf! haha!
keep up the good work chap!
-
exhaust parts mmmmmmm 2.5 inch mmmmm
the black box is my new boost controller
ar yeah man, thats gonna be sexy when thats all on!
-
nice horns man! lol
well, the engine build is well under way, engine came out today, stipped all the bits off it a want, such as the dual port heads, and alll that shizzle, and the new block with the uprated cam was put together as well, should be all in and running by the end of this week, all finished off with a full stainless, 1 1/2 - 2 - 2 1/2 exhuast system with 2 boxes, should be alright! haha! piccys of the progress will be posted tomoz
-
sounds nice man, got some piccys?
im really interested in the custom camber plates, got some piccys of that as well? and any info of where they came from etc?
-
i was gonna say, this sound very interesting! EA82 1.6! lol, first i heard, i will ask a few of the old boys who used to work at the dealerships when the old skool stuff were about
-
maybe a little heat? have you got some new bushes to go in?
-
yes, i like this! lol
yeah, gotta have the lifts, big chunky monkey workbench with a henchy vice on it, for all that pursuading you might need to do! a selection of large hammers, arc and mig welding, gas axe, some big spanners and you should be able to take on most things (this is what happans when your trained, and then work as a agricultural mechanic!) if in doubt, bloody well hit it harder! hahahha!
-
well, after trawling ea81 rebuild kits, i were bound to come across some EA82 stuff, hope this can be of help?
http://www.rpmmachine.com/engine-rebuild-kits-subaru.shtml
http://www.rpmrons.com/Subarukits1.html
just a quick 5 mins search! they look to be you can get the parts from them still
-
You have to realise that if you shave the heads, your valve timing changes since it's a pushrod engine. Haveing a custom cam of custom pushrods made is a must.
ah good point man, could you not grind the cam to help this then? i should be alright then, i got the custom bit covered! lol
-
I have built two ea81s with delta 240 cams big valve heads 2.00&1.94 valves 11.5 to 1 comp. and spfi It dyno @ 113hp 126 pounds of torque
it can be done its just not easy. Its took me long time and alot of work to do it.
oh by the way I'm a Machinist
SUBARU DUDE has rode in it
yes, i like it, what did you do to get 11.5:1? massive head skim or put diff pistons in or a combination? sorta thing i would like, comp like that, but you can only skim heads once! lol! the valves, how much bigger is that than standard then?
-
the EJ swap is probably better, but this lad has already had the heads done, so hes kinda got into it now, if you can get more lift on the cam, then you should be on more of a winner anyways than standard, do delta improve lift at all, or just shift the torque/hp around?
-
I think GD has got it right.

Just to give you an idea of how much time, money, and technology you'll have to throw at it.
Thats a fully built EA81 for aircraft use. (don't see why it could not be used in a car though, they actually say you can if you really want somewhere on the site)
115 hp.
$13,600.00
If ya wanna spend the money.........
But at that point you are just about halfway to just buying a new STI.
Granted you proly could pull more power out of an EA81.
I'm sure they are keeping it down a bit for reliability reasons being it's for an aircraft. (they also offer a supercharger for that one)
As in build it to handle way more power as it puts out so you don't blow it and fall out of the sky.
there is a reason for this pricing, and you got in the reliablilty terms, each and everyone of rons RAMengines are balanced, and blueprinted, as well as using THE best conditions to build in, and using the most expensive parts, such as forged pistons, and in house built dual port heads, and in house built injection systems, not forgetting the redrive units as well, plus ECU, so theres quite alot to add up there, to make it the price it is. just read the blurb, thers alot of work that goes into one engine! most of which, you could do yourself.
subaru as said, built the dual carb option with an improved cam, and got 108, out the factory, and they need to build stuff thats gonna last, not blow up after 30000 miles, so building it stronger, with higher compression figures and and improving the fuelling more so, i dont see why you couldnt gain another 12 hp on a factory conversion.
I think maybe something to consider, is the octance rating, if thats a contributing factor? it says that it can run 100 LL avgas, well, if so, 99 is obtainable in the country from the pump, and avgas is like 108 or somin as i say, if this a factor, i dont know, as i dont live in america, so dont know what comes off the pumps usually.
-
You won't make 100 HP, but you can improve it a bit. You are on the right track to make 85 or 90 HP most likely.
SPFI would be a better choice than the Weber.
GD
standard power out of the UK spec was 87, so im sure that 120 is more than reasonable, the US figures dont even match up right to mine, i put it on the dyno, and after 14 years, according to the U.S figures, its only lost about 5hp, which i know is pretty impossible!
-
lol, i get used to looking at dual ports though! lol
and lighten up the flywheel! mines in the shop now having a kilo or two taken off it, whack a bit of higher octane fuel in it, not sure what else really, unless you go injection, or forged pistons from RAMengines or some dualports from them, they would be quite a nice upgrade, just need to sort out thermostat somehow
-
im sure with a bit of manifold adapting, you could mount a pair of DGAV or similar webers, or some twin 40's like IDF's or somin, get the cam done, and a decent exhuast, dont see why somin like 120 aint in sight?
-
no matter how much i looked on rockauto, i couldnt find the bastard! lol! the guys who are doing my engine, forwarded me to this site actually, and we couldnt find it, it only seems to be in the 1986 year, grrrrrr, why they have to make it so difficult!
only 2 left at rock auto, jesus, these are getting thin on the ground! i thought they would be easy to get hold of!
many thanks guys, i should have one on the way, then the dual port, twin webered beast can be put together AT LAST!!!!!!
-
Right, the search is still on, these guys are being gay, and wont ship outside the US or canada, i dont know, pain in the arse!
can anyone put me forward to another site or contact? :-\
-
Go on... Used aircraft parts? SUB4 perhaps?
lol, errrm, maybe....cam as well, lightened flywheel perhaps, maybe some twin 40 IDF webers.....
-
WOOOOOOOOOOOO! THANKS MAN! sorted!
-
i cant find one properly for sale anywhere, i dont care where it is! everywhere is sold out, or obsolete, can anyone help me find a site or if they have one?
-
I think that part of it is that my first Brat spoiled me - it was a non-US-model MV that I owned in the UK, and running 90bhp in that one vs. 73bhp in the past couple I've had here set some expectations that I know won't be met.
ah you see, this is the thing, the UK ones i did think ran higher horsepower, like 85 standard or somin, i put it down to low octance being 95 here and high octance being at the most 99, and us is like 87-92 (i dont know, cause i dont live there!) so when i have seen factory figures saying below 100lb/s torque, its like AY?! but i got 100 and its detuned over time anyway! lol
put some race fuel in it, that will sort it! lmao!
-
wow, the chance to get EA82 in the UK, i think ive only seen it once! and that was non turbo
i would get hold of the engine if you can anyways especially if you can get the rest of the bits to go with it, theres somone with a truck bout 15 miles away from me with a EA82T conversion, it was on ebay a few years back
keep hold of it, and i might have it off you one day!
-
you need to remember about that lost power as well, mine was 14 years old when it went on the dyno last year, it produced 69 hp and 100lb/s torque and only having a K&N and cherry bomb, so you just adding bits to get your power back as it was to standard, maybe trying to restore that power you could do such a thing as heads off, give them a good clean up, polish up the valves, its all somin you can do yourself, and get the heads skimmed, bring up that compression a bit, also ported as well if you fancy it.
then tune the weber a tad richer, and you should be away for quite a bit more
and as said before, get a cam grind, but then you might as well go the whole hog and do the bottom end as well, which is what i ended up doing!
or you could do the really expensive thing and get some dual ports
thats what i ended up doing!

na man, i got ya 100%, it has been a concern of mine, and something i will attend to in the near future, just wanna get it back on the raod, to sort out any teathing problems with the engine, got any intial ideas on a solid RWD conversion? could i do somin with the original trans?
