sorry mr brat. its not that i dont read your posts or value the input. i just get mixed up in the details. a lot of variables in different engines/cars/crossmembers/trannys/etc some cars use a diff crossmember or even a different suspension on the same "model", based on an upgraded engine option. i just like to be 101% sure before i spend my hard earned cash and time. i got the engine from suberdave, and he mentioned that the ej18 burns really clean and thorough, efficient. i realize i dont need to take emmissions tests in a 1983 car. but im a big believer in not polluting more than necessary. and anyhow, id rather not breathe more crud than necessary. i get enough of my "quota" when welding. so i chose NOT to run my ea81 straight pipe, considering the combustion imperfection of the Carb. but now im kinda thinkin, you know, fuel injection..... less unburned fuel comin out the tail. so why spend more for the Cat conv if i dont need to.

i had the magnaflow front half exhaust on my ea81 brat. very nicely built, great quality. smooth bends, fairly thick tubing. thick flanges. real nice flow. my question is, has anyone tried the EJ system? can anyone tell me for 101% sure, does the ej22 exhaust fit the ej18? im thinking ill take the dualport collectors and about 14" of that, and butt-weld it to my ea81 magnaflow that i already have. or maybe someone WANTS my ea81 magnaflow assembly. 100 cash. id rather not ship.

ok fair enough, and thanks for the warning. even if it were possible physically, it sounds expensive. but i read in a well known source that subaru made the ej22 better by a new, low-friction, lighter-weight piston. 10% more power, 3% more fuel efficient. my question then, i suppose, would be: does anything like that exist for an ej18? new and improved, lightweight, low friction pistons?

i REALLY want to go. i keep missing brat meets cuz of mechanical probs. i have an ej18 im tryingto get in. should be done in a week or so. its going in my 1983 brat. gl. mostly stock.

thanks everyone. i do not race professionally, no class restrictions. i wanted to stick with same size as stock, i just wanted a newer engine. i already have the ej18 and i dont have a ton of cash left over after buying it. NOT that i got ripped off on the deal, he treated me good and its a very fair price i paid for the engine. gas mileage is a major priority for me. for 20mpg, i wouldnt even drive a brat. my stock ea81 was probably.... 28mpg. the ej18, i am expecting... maybe around 30 or 32 mpg. i guess i will just do the delta torque cam, and then hopefully some port work on the intake, exhaust and the chambers/throats. where do you guys all go to get 3 angle valve-grinds on ej engines? i just want a nice valve job, and a cam, and i suppose i will be happy. any input on who does good and reasonable priced port work in the seattle/tacoma/everett area?

where can i get some lighter, lower-friction, high-compression ej18 pistons? everytime i search google for "ej18 performance" or whatever, i get a ton of links, i open the links, and CAREFULLY read the pages, but they always seem to be for parts that fit an ej22. any info on what folks on here have done with their ej18s? portmatching? compression? intake work? headers? balancing? i am on a tight budget. but as time goes by, i can come up with funds to have machinework done. is there any reality behind my theory that BORING the ej18 cylinders bigger would add power, AND lighten it up, based on my impression that the block casting walls are relatively thick and heavy?

so what kind of power are we talking, with the solid lifters? another 1%? does anyone know if the delta torque cams ADD power? or do they just move it down the rpm range? does anyone have pics of the ej22 intake? are the runners BIGGER? or just straighter? cuz i know bigger runners hurt response. ej22 intake manifolds just bolt right up and fit it like a stock ej18 intake?

how does the whole "pitchstopper" rig work? is that totally fabricated? or does it ummm-----tie into the spare tire mount, maybe>? anyone have pics? i know this is a somewhat dated thread. and i realize that its not specifically about the pitchstopper. but they are at least semi-related. also, does anyone have SPECIFIC and exact lengths of the studs to the plates?

sounds like a LOT of pulling apart an engine MUCH more complex than the ea81 i just pulled out. lol..... but whatever, thats life. delta torque cam, already planned to do that. the rest, mmmmm, we will see. sounds like so much work for a couple horsepower. but the cam, yea, pulling down the curve sounds perfect. i dont care about MORE power, i just want it to come to me sooner when i step on the GO pedal. i cant complain about the ej18s power, really, i havent even tried it yet. working on getting the adapter plate from scott. no ideas on how i can find out WHICH ej18 i have? or how many angles my seats have?

are they like 3 angle, factory stock? any ideas? also, anyone know where a power curve chart is for sooby engines? i know the PEAK power of ea81s and ej18s and all that. just wondering when the power starts to show up. ive heard many on here complain that ej18s need to be revved pretty high to get their potential out. but compared to what? an ej22, of course, less displacement means less low rpm power, of course., of course. but how about an older, pushrod, equal displacement engine, like the ea81? is the come-on comparable, in HP and torque? to put it another way.... the ea81 lists a hp PEAK of 73hp @ 4800rpm --------------------------94trq @ 2400rpm but the ej18 lists THREE possible models, and i have zero clue which of those i even have in my garage right now??? ej181 108hp @ 6000rpm ------- 110trq @ 3200rpm ej182 113hp @ 6000rpm ------- 114trq @ 4500rpm ej183 118hp @ 5600rpm ------- 121trq @ 3600rpm ------------------ i got it from suberdave, an impreza, i THINK it was a 1994?? he told me, i just forget. anyone even know what made the different performance factors between the 3 ej18s? intake? different port design? cam duration? maybe compression? i dont care much about horsepower, or going over 70mph, 70 feels pretty fast in a brat. but i DO like to get going, and i Do like to handle hills without dropping to first damn gear EVERY time. so a fairly low torque response is a priority in my mind. if i already have the ej183, awesome. but thats a one in three chance. and even less, cuz i find that your odds of having the most ideal of 3 possible options is RARELY 33.3%. maybe 10%, on a good day. lol so here i am, i typed like 2 sentences about my subject line, and 3 paragraphs about my "p.s."......

I officially bid 80 dollars!!!

awesome, thanks for the extensive advice. thats a lot to respond to in an organized way, but first off, i must say, you may have misunderstood what i meant about the exhaust i had done. it is shrunk at the bends by maybe 10%. not the krinkle "accordian", just a smooth but restricted "pinch" sort of. as far as mt vernon, YEA thats far for me. but im gonna need to go up to Bham to see scott soon anyhow. only problem is, id nee dto bring my actual brat to you, in order to do that. but the catch is, it would be most convenient and "efficient", time and gas -wise, to combine a trip to mt vernon with a trip to Bellham. but my reason to go to scoot in Bham is my trans plate, to actually physically install my engine. until i do that, i cant drive the car, and so you see what im getting at, yea? lol..... dang..... life is hard. couldnt agree more on getting a GOOD quality exhaust. i love my brat. ive gone thru a fair number and VARIETY of cars. and of all of them, my brat is my favorite. brats are a great combination of FUN, PRACTICAL, PRODUCTIVE, FUNCTIONAL, AFFORDABLE, RELIABLE, and SPORTY. yea, they are not a 2 hundred mile per hour car. hell, a brat isnt even a ONE hundred mile per hour car. with the ea81, i was working it fairly hard just to see 75mph, lol..... but it FEELS fast. its quick at REAAAAASONABLE speeds. so what if your car can do 256mph, bugatti, you never will, that situation just doesnt exist. my brat is about as fast as i feel a need or desire to ever go. truth be told, im a big believer in survivalism, self-reliance, producing your own food supply and potentially your own power, living simple. and along that line of lifestyle, a Brat seems to me, one of the best tools/vehicles a person could ever own. more so with the original ea81, because of simplicity and weight, ease of repair and maintenence. but whatever, these days, i dont think many small-town mechanics would have any problems fixing an EJ18, be it Tibet or Peru or a remote fishing village in newfoundland. whatever. im working on maybe hping SKR scott will trust me on advancing me the trans adapt plate ahead of time, so i can then drive up to him to pay him back. not sure how that will go, and i have no right to DEMAND it, or whine if he isnt willing to do that. im just hoping, because it would streamline my effort to get this brat back on the highway, including to you, for example, to get my exhaust in order. im thinking that i can cut off the impreza exhaust, maybe a foot on each side, just so i have SOMETHING to bolt on there, for that minimal backpressure. ive heard the ZERO backpressure can damage your valves, and recess the exhaust valve seats. we shall see how scott feels about all that hope of mine. i want to be clear, i have no DEMANDS or pressure against him, and if any friends of his, or himself reads this, please dont think i am aiming to manipulate or guilt-trip or ANYTHING like that. its like the lottery. i HOPE i win it, but im not gonna talk smack, and badmouth or spite the lottery if i DONT win.

also, in my previously chosen exhaust shops defense, they work on real nice cars, and i basically showed him a relatively small amount of cash, and asked him if he could make it happen. the welds are goods, and he lined it up nicely, and tucked it away, up higher, with more clearance than Fuji/subaru built it in the first place. my guess is that, correct me if im way off track here, but i think maybe that if you have like 4 or 5 feet of good, smooth, high flow exhaust, from the engine, to the Y, thru the Cat, and 2 more feet after the cat, if the last 5 feet are less than perfect, maybe the exhaust has already cooled and slowed enough by that distance from the engine, that a few pinches arent even a measurable factor??? just my pet theory.

thank you for the detailed response, by the way. i appreciate that. my understanding of exhaust and backpressure was that you could get the best low and mid power, and quicker throttle response, by using the smallest possible tubing, with the smoothest run, front to back. i know for sure that a long straight narrow passage creates the highest velocity and smoothest escape. thats bernoullis principle. thres been a lot of car craft articles knocking the trend toward 3 inch exhaust on chevy 350s and such. i know because of my buick, that, as you said, a big bad boy like a 60s big block iron beast can get plenty of fart out of a 2 inch pipe, as long as your mufflers are decent. my brat has a 2.25" inch cherry bomb. but not the stereotype "cherry bomb" glasspacks. its the turbo type, like flowmaster uses, but WAAAAy cheaper. boggles my mind how some guys will throw away 2 hundred cash for a damn muffler. just shows that the hot rod crowd often has more dollars than it has sense. i think the subaru crowd in particular tends to think things through, and make a habit of UNDERSTANDING how and why things work. and not being so quick to jump to the biggest is better philosophy. some might even take the freudian view that subaru owners, as a general group, may have bigger than average ummmm.... tools. and so we dont feel the needs, unlike the Hummer and escalade crowd, to prove anything to total strangers. we like subarus, and subarus are a well-designed, and efficient machine. excuse that tirade, lol, just thinking thru my keyboard again. but yea.... sounds like you personally do exhaust for a profession, 3eyes. i would send the work to you, but the name of your town isnt familiar, so i assume its far away, and i dont want to deal with shipping all that ************e. and anyhow, id prefer to get it built ON my brat, turns out better that way. any chance that you know any specific shop in seattle/bellevue/tacoma area?

yeah duh, my bad..... i had that file in my hard drive, the processor just wasnt accessing it. or, another metaphor would be: i knew that floor was on my building, my elevator just didnt stop at that floor. i guess AMC is kind of a little known and little understood make of cars. no disrespect meant to the amx or javelin though. they are bad rump roast cars. ambassadors are kind of an ugly turd though. buick had a 401 nailhead in the early and mid 60s. i think up until like 64. then there was the 425 nailhead after that. im a buick man so my mind automatically went to buick.

a 401, eh? is that on a wildcat, or a riviera? i dontthink skylarks came with those from the factory. or GS's. skylarjs, iirc, only came with 300s or 340s. my riviera has the 430, and it had no engine options in 67. one possible engine, one possible tranny. that 401 is a 4 barrel? or a 4x2?

hey mr. brat. i just today saw a clip of you at wcss 11 doing donuts in the mud, on youtube. sounded great. then again, computers really dont do car exhaust sound much justice. im not sure why youtube has so many short clips trying to show off their fancy exhaust sounds, because its never impressive. a 1967 426 Hemi sounds pretty bad on a youtube video. but whatever. what im trying to say is, your brat sounded at least as good, if not better, than any other nice performance car ive ever heard on a computer. lol... p.s. that wa smeant to be a compliment, but came out confusing..... whatever

i just got a nice magnaflow front exhaust <from the heads to the Y and cat, and then another 24" after the Y>. i paid a lot, at least by my financial standards. it was great, i was happy, proud of my nice exhaust, then i took my ea81 apart for various reasons. <spfi pistons, port+polish, head decking, new gaskets, clean crud+sedinment out>. so i never got it back together, lame, pathetic, whatever, i know, i suck, shame on me. but WHATEVER. now i have a very nice ej18 THANKS SUBERDAVE!! its not in yet but soon will be. got a trans adapter lined up for tomorrow. which gets me to my point: all i need now is a nice exhaust for my ej18. what have people done in the past? i know for sure a few of you guys have ej18s in your brat. jerry does. not sure if ej22 has the same exhaust set-up. but either way, can someone tell me what they would do about that? is there a good shop with a mandrel bender, and reasonable prices? i got mine done at a small local shop in maple valley. it has the pinches at every bend, i had planned to eventually get the back half redone nicer. the front half, as i said, had the magnaflow, which had VERY nice smooth bends. sounded better, looked better, WORKED better. i got that part on ebay for maybe like 185+shipping. it was specifically for a stock brat with ea81. they have the same thing right now for a 95 impreza. but its almost $100 more than the ea81 part, even though they are identical except for the dual port head design. also i have no clue if it would actually FIT my brat, where the one a bought was designed for my exact car, this is for an mid-90s impreza..... http://cgi.ebay.com/ebaymotors/MagnaFlow-Direct-Fit-Catalytic-Converter-23875-/370522932331?pt=Motors_Car_Truck_Parts_Accessories&fits=Make%3ASubaru|Model%3AImpreza|Year%3A1995&hash=item5644e3446b so i guess i should just cut off the first 12", or so, of the y-pipes, and get a whole new custom exhaust back from there? any advice or previous experience would be UBER-appreciated.

[ATTACH]8770[/ATTACH] the tube bumper might be improved with streamlined ends like THIS:

also, on a side note, no rush, but i am definately excited to see what your skid plates end up like. mine is strong but really cheap and heavy mild-steel plate. i had thought about aluminum diamond plate cut off a junkyard truck bed-box. weak but easily and cheaply replaceable. but if you make some nice ones i will probably line up to get one.
