WJM Posted June 6, 2004 Share Posted June 6, 2004 Lets cast some 4 valve heads for the EA82T. Go camless. Make the ports on the heads HUGE...well, as big as the current EJ engines so we can bolt on the high performance/racing headers and manifolds. Im talking HUGE ports tho, and HUGE valve ports here. MASSIVE FLOW. VF39. HUGE throttlebody. MASSIVELY high flowing custom intake manifold....massively perfected air/water IC, and 4 inch exh from the turbo back. No cats...unless they make a 4 inch one....megasquirt and DIS, anti lag (ut oh, getting expensive now), and....well, some other goodies as well. Um, me thinks good for aobut 450-500 hp.

JonOfScio Posted June 6, 2004 Share Posted June 6, 2004 hey man, that might even compete with my "secret" engine. I think insanity describes both. what about you? Link to comment Share on other sites More sharing options...
Myxalplyx Posted June 6, 2004 Share Posted June 6, 2004 I just want to boost my XT6 to about 18psi (Intercooled with EA82T pistons) with a 50hp shot of nitrous from a wet kit. Is that asking too much? :-\ Also, I'd like to purchase a built up EA82T with a built up automatic transmission. It only has to weigh approximately 2400lbs and put out 180hp and torque to the wheels. That's all! :cool: Link to comment Share on other sites More sharing options...

archemitis Posted June 6, 2004 Share Posted June 6, 2004 this is one of those what if threads, like twin turbo subarus, and 200 hp ea81s. what if i crapped a supra motor into my hatch? what if? what if.... Link to comment Share on other sites More sharing options...

If I'm lucky, I'll know by the end of summer. Besides, there's something to be said about having a 2.7-T. Displacement! *Roar* Link to comment Share on other sites More sharing options...
Adam N.D.J. Posted June 6, 2004 Share Posted June 6, 2004 I like the idea of an ER27-B, but thats just for my application. Hmm, a 7MGT-E in a Hatch, I can get my hands on one of those motors fairly easily, then it's just a matter of making the room, wireing it up, and putting in a new rear end to handle the power. Hehehehe Link to comment Share on other sites More sharing options...
bushbasher Posted June 7, 2004 Share Posted June 7, 2004 I wanna see a twin turbo er27 or eg33 Are the er27 blocks similiar enough that you could use ea82t pistons to lower the CR? Link to comment Share on other sites More sharing options...

I hate to tell you this but I AM going to have a twin turbo EA81 just for the record. Had to make that clear. As for your idea WJM, that would me such an awesome project but it would be major $$$.

JonOfScio Posted June 7, 2004 Share Posted June 7, 2004 It looks to be, from research, and from old posts that I've read, that an ER27 is almost literally, two more pistons added onto an EA82. IE: They have the same bore and stroke. And so then probably the same pistons... you could do a 9.5:1 SPFI swap or a 7.7:1 turbo swap... if you really wanted the most power from any turbo engine, you get as close as you can to as high a compression number as the engine will take. run the thickest oil it can take, an oil cooler, and an intercooler. oil coolers help everything, especially the heads, and intercoolers help against detonation. rule of thumb : higher the boost, or higher the CR, higher the octane. Since they wanted something reliable that could run on 87 octane, they did 7.7:1. oh, and I am going to have a 200hp EA81 as well. Anybody that thinks this is funny, will have to rethink themselves when I'm done. I've seen a 280hp L20 Datsun motor, NATURALLY ASPIRATED. What stops me from hitting 200?

bushbasher Posted June 7, 2004 Share Posted June 7, 2004 I think that the fact that your head has one intake port and one exhaust port is going to prevent you from hitting 200 Are er27 heads almost exactly the same as ea82? Can they have the same cracking problems? Do they run all 3 exhaust valves into one exhuast port? These er27s are curious motors! Link to comment Share on other sites More sharing options...
88rxsedan Posted June 8, 2004 Share Posted June 8, 2004 the vg30et in my nissan has 2 valve per cyl also, that didnt stop it from putting down over 200hp at the wheels NATURALLY ASPIRATED.. If i were to swap the pistons and get some cams and some boost through it, i dont think the 400rwhp mark would be hard to acheive at all.. same goes with my isuzu impulse. 2.0l displacement, sohc, 2valves per cyl. I havent been to the dyno yet, but at 16psi, im guessing its going to put down well over 250 dont let the lack of valves detour you... with proper "work" it can flow more than enough air to generate PLENTY of power.. with a built bottom end, lots of boost and proper tuning, i see NO reason why an ea82 couldnt generate 250+ hp Link to comment Share on other sites More sharing options...
NoahDL88 Posted June 8, 2004 Share Posted June 8, 2004 I don't want to take sides of this argument, but there is no way you'll hit 200 with a EA-80 anything the crank won't take it, it'll crack like a twig. however, there are 4 port EA-82 heads, www.ramengines.com has them, they are very expensive, and even with their custom intake and fuel injection they only put down 140, so, i hate to burst any bubbles, but i'm gonna have to wait and see it before i believe it. The EA-82 and EA-81 are not engineered for power, with single intake and exhaust, and only 2 valves, theres really not a lot of potential to these engines, but by all means that dosn't mean you shouldnt try, it just means that you're not going to go too far with these engines.

88rxsedan Posted June 8, 2004 Share Posted June 8, 2004 your wrong, forced induction and stronger internals, well, nevermind - just watch and see.. the cranks are stronger than you think, the rods are also.. the weak link in theese motors are the pistons.. im talking about forced induction of course, n/a is a whole different story..

bushbasher Posted June 8, 2004 Share Posted June 8, 2004 88rxsedan, the ea81 heads have one port going out of the head for exhaust, one port into the head for intake. As in one pipe bolts to the head for an intake, and one pipe bolts onto the head for exhaust. Not just 2 valve/cyl. Plus the heads do not have enough room to do alot of porting. With ram performance custom heads, high compression, a cam, and a better crank you could possibly see 200. mpfi heads have two intake ports but still just one exhaust port.

JonOfScio Posted June 8, 2004 Share Posted June 8, 2004 I likened my engine to the insanity level of what WJM is presenting. I'm not about ready to reveal it to the whole board, but once you see it when I'm done, you'll realize that "one port is no good" sh1t won't work in this application. I know that without a hint it's kinda hard to imagine what I'm talking about, but I'll just leave it at that it's not N/A and will look REALLY REALLY cool. And it is INSANE. Just ask WJM, he knows...

WJM Posted June 10, 2004 Author Share Posted June 10, 2004 The exhaust port on dual intake ports on the MPFI and TURBO EA82 are plenty big to accomodate 250 HP at the crank. I think the rods and crank are strong enough for that...and possibly to the 300 hp mark. I would be happy to get 250 from the EA82. I really think that the stock pistons are fine...the 87+ pistons atleast...they look to be better designed than the first gen EA82T pistons. Ive got a set of 1 gen and 2nd get. Actually...many sets of each. Anyhow, Jon's idea is pretty mean and nasty after its all said an done...i believe that it should be pushing 200 at the crank...out of stock heads (mostly) with just one intake and exhaust port on each head.... The real key to the EA82T, like i topic'ed on before....is CAMS, HEADER, and TBE (turbo back exhaust)....plus a 3" cone filter bolted on the MAF/Air Flow Meter....and then go from there. The Spyder intake with an XT6 Throttle boby bolted on would also add many ponnies, as well as a good IC setup. I believe those items, with the 677-260 Delta cams, would yeild around 200-230 crank HP from the EA82T. With the 272 cams, which are pretty much racing only, and a larger turbo...say, TD04, 300 would not be so far off. Link to comment Share on other sites More sharing options...

archemitis Posted June 10, 2004 Share Posted June 10, 2004 these are subarus, you cant take a 65 hp motor and get 200 out of it natuarally aspirated, with stock heads, even heavily modified stock heads. sorry Link to comment Share on other sites More sharing options...
88rxsedan Posted June 10, 2004 Share Posted June 10, 2004 every motor has a limit, but IF steps are taken properly, and all is done right, you can generate ALOT of HP, from any motor.. hell, theres a 1 liter bike making over 500hp to the tire with a lil boost.. i think its possible, and i wouldnt doubt it if someone actally did it.. its definately possible Link to comment Share on other sites More sharing options...

MorganM Posted June 10, 2004 Share Posted June 10, 2004 With enough time, effort and money; anything is possible. Want 200+ HP out of an EA series engine? Just apply more time, effort and money. Pretty soon youll just have your version of what Subaru already did... EJ series engines. Want lots of power in your Subaru? Just buy a damn EJ20TT, or an EJ25T, or an EJ22T, or one of the H6 engines. There is a reason Subaru didnt make 200+ HP out of the EA series; its not worth the time, effort or money.
