audio_file Posted February 29, 2008 Author Share Posted February 29, 2008 You asked for opinions..... But I respect your desire to remain true to the original car. I think a lot of the problems with the EA82T builds I have seen is that people kept pushing for more and more power. I think Calebz' date=' Subarutex, WJM are a few people that come to mind who have done some extensive work with the EA82Ts. Do a search of their old threads and glean what you can from all of those old posts and then do what they did right and avoid what they did wrong. I have never had a working EA82 so I am biased towards them. I like the old EA81's and since I have overcome the mental fear of doing wiring work on a EJ swap I am a big fan of that. I am not saying get the biggest baddest engine out there. I am saying that you can get a decent $200-$300 EJ and do wonders with it. My RX is gonna have a EJ22T. I want to get about 200 hp (about 150 bhp) out of it initially. That's WRX territorry in terms of hp to weight. Total build is going to be under $3000. So if I compare it to a 2002 WRX that can be bought for about $10,000. I am spending 30 cents to the dollar. The final build goal is going to be around 270-300 hp (i want 200 bhp) That should bring me into the 4k-5k range. But then I would be in STi territory. and spending 9-11 cents on the dollar. One thing that you might want to consider it modifying your hubs to work with 5X100 rims. If will open up a whole new world of rim options, once again my opinion. BW[/quote'] I totally understand (and thank you for the opinion!!) all of the benefits of going to an EJ engine. Who knows, maybe in the not too distant future i'll get sick enough of the headgaskets, lack of aftermarket support, etc. of the EA82 that i will end up swapping, and 300hp would sure be fun but for now, as you said, i'm trying to stay faithful to the original design, albeit with a larger turbo, and the addition of the necessary support parts (TMIC, BOV, fuel system upgrades, etc.) i will also be doing that 5 lug swap, not only for the wheels, but also i think (i hope!) suspension parts (coilovers, bushings, sway-bars, brakes) will be easier to find after a lego/xt suspension swap. **P.S. one eye and I (say that 3 times fast) went to the pullapart yesterday and i found a nissan 280!! took all six injectors out of it for $9.72 Quote Link to comment Share on other sites More sharing options...
s'ko Posted February 29, 2008 Share Posted February 29, 2008 i will also be doing that 5 lug swap, not only for the wheels, but also i think (i hope!) suspension parts (coilovers, bushings, sway-bars, brakes) will be easier to find after a lego/xt suspension swap. Easiest way to do this would be to get EJ fronts and Ren man's adapter when it comes out. The rear wheels would stick out a bit and it might chew up bearings, but it should be ok for road use.

I believe it has to be a turbo, otherwise they are the same flow as the stock EA82T injectors. Heres a link to a search I just did.

one eye Posted February 29, 2008 Share Posted February 29, 2008 Since all this is way over my head I would just like to add to all this, I just want to see the big boom that it makes the day she lets loose and you end up shooting the bottom end out, and into or maybe even through the intake manifold. I don't hope that it happens but if it does I just hope the camera is rolling. If that doesn't happen I hope that it is the fastest RX in the States all said and done, Then I can say, "ya... he built that thing in my garage."

audio_file Posted February 29, 2008 Author Share Posted February 29, 2008 D'OH thank you very much for the linkey . . . now i'll be looking for "brown tops" anybody need some "same flow as ours" green top 280 injectors? i guess it's a good thing i only spent 9.72 chris Was it a turbo 280?

Gloyale Posted February 29, 2008 Share Posted February 29, 2008 I was told the flow rate for the 200sx injectors is 200, not 188. I purchased a set of 6 new for $42.00 This is what the guy told me the flow was. Quote Link to comment Share on other sites More sharing options...
Subarutex Posted March 1, 2008 Share Posted March 1, 2008 Congrats on the RX. Do some searching for my name, for stuff I did to my old RX. Its quite a read. I would say... if it can be done to a RX, i've probably done it! I'm south a bit from you, but hit me up if you want to talk shop. I can show you the right path, and give you a ride in something that will make you stray. Again... Congrats on picking up one of the sexiest cars Subaru made in the 80's Also, I could probally hook you up with a ride/ or check out, one of the fastest EA82T powered cars I've ever been in (even faster than my RX). I showed him how to do it all too... Even better, would be to hook up with NinjaBen (??) I think he has my old RX now, while not nearly as modded as it once was, I can sure point out quite a bit on it. Also, there is a local guy (witchhunterperformance.com i think...) that does injector cleaning and flowing.... Quote Link to comment Share on other sites More sharing options...

Thanks! and believe me, i've been a'searchin late at night until i look like this guy > and i have seen a few of your old threads! interested to know what might "make me stray", keeping in mind i've owned and driven a few of the "cool guy" cars available these days . . . thanks for any help, this has been and will continue to be a learning experience for me, the first real block up rebuild of a forced induction engine for me, and my first experience working on soobs in general. jeff (one eye) and i put some work into the RX today!! jeff took care of that horrible red hood for me (did a great job "murdering out" my hood ) and we ran it through a much needed carwash which took off most of the moss and gunk i removed a few unnecessary parts from under the hood and got a much better view of the engine that came with the car . . . it doesn't look too bad! vacuumed up the baking soda i threw down on the carpet a few days back to get rid of the mold, (not entirely successful) and was so happy with the outcome of the days work that i decided to drive the car home (from a garage in mt. vernon to near boeing in everett) getting it on the freeway for the first time, what a blast!! the ol' girl got up and went very well, and aside from an apparently very confusing temp display on the digidash (went from 1/2 temp to above 3/4, cycling between those two temps about every 30 seconds ) i had no problems here's a few pics after the hood fix and the wash . . . now, we start to build an engine!! chris Quote Link to comment Share on other sites More sharing options...
Turbone Posted March 1, 2008 Share Posted March 1, 2008 Sounds like the the thermostat is out of whack. Get a OEM replacement for it and I suggest asap. Overheating will kill the EA82T, that and overboosting I'm one of those that have been thru a few engines in my RX :-\ Quote Link to comment Share on other sites More sharing options...
Skip Posted March 1, 2008 Share Posted March 1, 2008 listen to the Turbone he is da man when it comes to these Also I had a 87 GL-10 digidash do that, it turned out to be a bad ground for the dash components. The ground (get this) is under the pass side front intake manifold bolt. Quote Link to comment Share on other sites More sharing options...
audio_file Posted March 2, 2008 Author Share Posted March 2, 2008 thanks turbone and skip, i'll check that tomorrow . . . skip, it doesn't surprise me one bit after fixing that injector wiring issue in Jeff's XT (splice under passenger seat rotted away) thanks for the point in the right direction last night while driving the RX around town it started to sputter, especially when going up hills and around corners. i didn't think too much of it, until it finally sputtered and died . . . "hmm, two bars of fuel showed on the dash, so i'm obviously not out of gas, must be something else . . ." my very patient girlfriend who was already humoring my need to drive a rusty, moldy, not totally reliable soob RX sweetly suggested that we at least try putting some fuel in the car. with a bit of luck and a whole lot of swerving we limped the car to a gas station, and $20 later, the car not only drove perfectly, but it also showed a full tank. as much as i wish $20 could buy me in the neighborhood of 13 gallons of fuel, i'm thinking that maybe the fuel gauge has it's own gremlins and . . . the indicator lights for 4 Lo and Diff Lock don't always work, just when they want to. ahhh the fun quirks of an old machine chris listen to the Turbone he is da man when it comes to these Also I had a 87 GL-10 digidash do that, it turned out to be a bad ground for the dash components.

audio_file Posted March 2, 2008 Author Share Posted March 2, 2008 at what psi is an EA82T overboosted? a good reference point to set the boost controller at eventually would be greatly appreciated . . . thanks chris Sounds like the the thermostat is out of whack.

Turbone Posted March 2, 2008 Share Posted March 2, 2008 Anything over 7psi is over for a EA82T. I blew the ring landings off of my last one at 12psi, Did the fuel light come on when you were out of gas? Quote Link to comment Share on other sites More sharing options...

Subarutex Posted March 3, 2008 Share Posted March 3, 2008 Really... overboosting depends on the turbo. And by overboosting, most of us mean, you generate more boost than fuel or timing can keep up with. This leads to detonation, which in turn makes pistons fall apart, and head gaskets to fail. Stock turbo.. i'd say stick to 11psi or so, and do it on premium gas (chevron preferred). If you are running a larger turbo (vf11 or td04) i'd stick to about 8-9psi. These recommendations would be for a car with no additional mods (intake, exhaust, fueling, timing, etc...) Before I went way crazy with my old RX, i was running 13-14psi on the stock turbo (right at the edge of its efficency) with slightly bumped timing, custom downpipe and exhaust, and one step colder NGK spark plugs and 8mm wires. Oh... and intercooler. Thats a VERY important modification. Probally should be your first after doing intake, plugs, and wires. Quote Link to comment Share on other sites More sharing options...
Turbone Posted March 3, 2008 Share Posted March 3, 2008 If you do decide to up the boost, make sure you get a good boost controller. I bought one off Ebay that was cheap and paid the consequences It was sure fun at 12lbs tho :-p Quote Link to comment Share on other sites More sharing options...
Caboobaroo Posted March 3, 2008 Share Posted March 3, 2008 My last EA82T build (there have been a couple), I was running an SPFI shortblock with rebuilt gen 2 turbo heads, OEM head gaskets with new headbolts, Delta 260 cams, spyder intake, WRX TMIC, TD04 turbo, Samco intercooler hoses, AEM cold air intake, Megan Racing 3" bellmouth downpipe, Nissan 280ZX turbo injectors at 388psi on the fuel pressure. Did awesome until I gave it too much (12psi on the TD04 with really no fuel management) and blew the rings on two cylinders. Decided on this to do it right and go with a turbo'd EJ instead. So, more on the 3-doors. All 3-doors I believe have the rear wiper. My '87 GL has it, I've seen it on all the other ones I've seen throughout 5 states. Like Tex, if you do some searching under my board name, you'll come up with a lot on EA82Ts. I also have lots of pics of my old RX build and the new one at that. Congrats and welcome to the EA82 3-door club! Quote Link to comment Share on other sites More sharing options...
audio_file Posted March 8, 2008 Author Share Posted March 8, 2008 This week's update . . . Jeff and I took the longblock i bought and tore it down, dropped the heads of for machining and testing, the machinist said they were the cleanest subie heads he'd ever seen so he shouldn't have too much work to do . . . some pics of the block torn down, and cleaned up a bit, pics aren't great, just used my phone (too little light) here's what happens when you drop a camshaft housing . . . fortunately Jeff happened to have an extra one (or 5) laying around, so i just swapped the cam out to a new casing (whew) went a little crazy with the cheese whiz on cleaning the block, i'm a little worried that if a soob engine is too clean it might not run chris Quote Link to comment Share on other sites More sharing options...
audio_file Posted March 11, 2008 Author Share Posted March 11, 2008 alright, so i've picked up my machined heads (not to be confused with the epic and meaningful smash hit "Machine Head" by Bush ) and they sure are purdy. machinist said he removed at most .006 (6 thousandths). a couple of ?'s . . . 1) shouldn't have any issues with the original head bolts being too long with so little material removed, right? 2) i purchased a pair of McCord (by Clevite) "Grafpak" graphite type HG's. does anybody have any experience with these? they say they can handle 1500* and that they require absolutely no re-torquing (not bad for a 9.99 fleabay find eh?) 3) in reading the USRM, there's a thread that states that torque specs aren't a constant, meaning sometimes subaru's torque recommendation changes, can anybody tell me what the current torque rec is for this EA82T MPFI? thank you all!! chris Quote Link to comment Share on other sites More sharing options...
one eye Posted March 11, 2008 Share Posted March 11, 2008 Is it 42ft lbs for the heads and 14ft lbs for the intake? That's what I've always done. Jeff Quote Link to comment Share on other sites More sharing options...

I can't recall stock torque specs... I know in my time, I was all over the range. I think I topped out at 75 or 80 ft/lbs. There is also a particular pattern you are supposed to torque... with like 3 steps! Although I hear places that rebuild these w/ warrenty's do it all in one step, just follow the pattern! You'll find out pretty quick if those gaskets are good or bad Quote Link to comment Share on other sites More sharing options...
