I've still got a bit of insurance money left after the bastards totalled my old diesel Mercedes.. and after viewing yet another video from Oz and seeing all those bad rump roast bumpers on there, kinda got me thinkin "I must have.." for the ol' camo Brat. Since long-term plans include a hydraulic winch, it also has to include the bumper to go with it. In particular, I am very fond of the bumper on Subarino's blue hatch.. hopefully he will check in and give me info on it. So how bout it folks? Those of you that have bad rump roast bumpers, pls post a couple pics of them... especially if you've got a winch stuck in it, lets see it.

Copper tubing w/ mechanical gauge FTW!

:slobber:

Damn it... has to be in Wisconsin and not some place close... like Atlanta, or hell, even Memphis.... I'd be willing to drive up to 600mi for a JY like this, just to look around. Freakin 1100 mile trip. Unacceptable. They must pack up all their junk, and move some place closer to me!

So then, if I understand correctly, with the EA82 using a hotter cam, with less effective CR, the 9.5:1 pistons, in the EA81, with the stock cam, should give an even higher effective CR than 9.5:1? Hehe.. 9.55+:1? All this while still running regular 87 octane unleaded fuel with no detonation? Should be good for at least 95HP or so... Or am I reading too far into it? I probably should stop thinking now while I'm ahead right? This is turning into a very good discussion.. should help future search results greatly.

misshapen? Out of shape.... tsk tsk. I want 100 more sit-ups out of you to lose that gut. According to all I've read, including the HTKYSA books, the EA71 is the 1600cc OHV motor, the EA81 is primarily the 1800cc OHV motor, the EA82 is the 1800cc OHC motor. Now I say primarily with the EA81 as in the book, it also states that in the early years (78-80), there were 1.6l "EA81" stamped motors.. so according to the texts, the EA81 came in both displacements, either by design or by mistake. However, in the context of USMB, the term EA81 always refers to the 1.8 OHV.

Those are pretty much the answers I was expecting to get, yet at the same time, has never been officially answered in the forum....least not in any of the search results I've read over the last couple weeks. I knew EA82 SPFI motors ran fine at 9.5:1, but was rather curious how an EA81 would run at 9.5:1... I know head design and such plays into how much compression can easily be turned up on any given motor.. just didnt quite grasp it with the EA81. I'm not wanting to have to do any crazy mods to keep it running.. just a simple swap and go. So, pretty much leaving things more or less as they sit, only swapping to SPFI pistons, keeping the Weber and ND dizzy, 9.5:1 should run just fine? Sweet. Time to start on phase 2 of my evil plan....

Here's mine..

Thats kickass. We need photos....well, I need photos.

The topic says it all. What is the maximum compression that an EA81 can reliably run on pump gas? Mainly, what CR is the max for both ends of the pump gas spectrum (87 - 93)? Re: http://www.ultimatesubaru.org/forum/showthread.php?t=65542

So the front diff assy is the same P/N from 1985 to 2004... check. So as I gather, a 5spd D/R could be swapped to a legacy front LSD with no issue. (note to self: swap from 4spd D/R to 5spd) I guess the next question, pardon me for asking as I dont recall reading about it in the thread, is of the various gearsets.. will the 4.11 and 4.44 also pop into the case without modification? I ask this as I've read in various other threads that those two sets, 4.44 in particular, uses a larger diameter ring gear. And, as a logical extension of the above question, what sort of options exist for the rear end? Or is dropping the R160 in favor of an R180/200 the only option to fit those extended gearsets? *prepares to cut up a 280ZX for its 4.11 R200 lsd*

Bumpy Bumpy... The .net to .org name change yesterday farked me up big time.

For those of you that have made the swap to propane, in either a bi-fuel or 100% LPG configuration, I've got some questions. On my Brat, I'm going to do the swap to LPG for sure.. however theres some questions I'm trying to sort out so I may decide how to proceed. I recognize that a LP swap on a stock EA81 will result in a ~10% power loss.. how many of you are running this way? Any thoughts, things you'd do different? What about those of you using forced induction? LPGSuperchargedBrumby comes to mind.. are you running stock internals? What kind of supercharger are you using? Anything you'd do different if you were to do it again? My real question: Anybody running EA71 or EA82 (spfi, or carb) pistons with LP? The EA71 pistons should bump the compression to just under 8.85:1 based on reading older threads, and EA82 carb would be 9.0:1, EA82 spfi would be 9.5:1. What sort of limit is there with regards to CR if I was to use any of these in a bi-fuel configuration? Could I run 9.5:1 in a bi-fuel config with 89 pump gas? Now here's the options as I have them now.. and I request the board's opinion. I can either simply fix my headgasket issue as it sits, and do the LP bifuel swap on my stock block, or since I intend on keeping the Brat forever, just biting the bullet and getting a new block from CCR with EA71, or 82 spfi pistons swapped in. What route would be the best... my intentions are a bi-fuel config, while keeping use of 87(89, regular grade) pump gas. Thx.

I have intentionally stayed out of the gallery this year, as I havent had the time to get out and grab some new pics of the Brat in its native sandy Florida habitat... To make things worse, its currently not running due to a slow leaking HG that needs to be replaced. Damn milky oil. So, here's some older pics to show its still around... Private land outside Ocala National Forest Apalachicola National Forest, home turf, ATV pit Still debating what route I'm going to take to get it back on the road.. either going to rebuild what I've got now and swap to LPG, or get a CCR block with EA71 pistons and then swap to LPG. Either way, I'll have to make some new pics in the next month or so...

I remember seeing several pictures of several Brats with solid rears over the last couple years, none with solid fronts yet.

No, but I believe I'm going to end up being the first to try. Gotta replace them headgaskets first.

After reading all the issues people have had, its making me rethink the idea of swapping cams...

I was thinkin there were still EA81 crates out there.. I'm afraid of the EJ20 swap...

I'm lazy. Linkage pls?

Rather than gathering up individual parts, why not go this route and get it all at once? http://cgi.ebay.com/ebaymotors/JDM-Subaru-Impreza-GF8-EJ20-EJ20G-M-T-AWD-Engine-Tranny_W0QQitemZ110032348367QQihZ001QQcategoryZ46098QQrdZ1QQcmdZViewItem EJ20G, MT5 AWD tranny, ECU, harness, etc. If I wasnt afraid of the swap itself and the wiring mess (not to mention the possible shearing of axles and other twisted parts that cant handle the extra power), I'd just grab something like this for my Brat and ride, since everything is included. Best of luck with your plans... .R

Since it disappeared from the USRM twice, and I've received a few PMs asking where it went, here it is. Still in the same place as its always been. ---begin USRM cut http://random.removed.us/altswap.html

Why? Its not like its fuzzed out while driving on the street, where many many more people can see it. I never understood the logic behind doing that. Back on topic, that is one sexy Brat. Is she just as hot? :cool:

Well, I didnt sell it, and dont intend to, but I bought my Brat for $1500.

My suggestion is to move back to Albany.

Exactly. ^^^ Is his Brat mostly stock? If so, tuneup it most definately is. As with mine, even lifted 6" and rolling on 31s, I can still attain 70 and hold it fine. Only real engine mod is the Weber. Which isnt *that* big of a difference from a stocker...
