rxleone Posted May 8, 2010 Share Posted May 8, 2010 Hey fellas, stumbled across this info for a 1991 Legacy on AUSubaru.com - thought it might be a bit of interesting reading for you carb-less Stateside folk! FSM EJ Carb Section FSM Dizzy Ignition Section Also on another note, now I've finally gotten back into a job, expect to see a carbed EJ22 showing up somewhere along the lines in my EA82 wagon - using all Subaru parts giggity giggity goo Link to comment Share on other sites More sharing options...
Yo'J Posted May 8, 2010 Share Posted May 8, 2010 Well thats nice info to have layin around! Thanks! Did you get those carbed cars there? Link to comment Share on other sites More sharing options...
rxleone Posted May 9, 2010 Author Share Posted May 9, 2010 Well thats nice info to have layin around! Thanks! Did you get those carbed cars there? Yeah, in the EJ18 - not the EJ16 as it's labeled. Should be a good little runner, and a straight-forward swap too Link to comment Share on other sites More sharing options...
bratsrus1 Posted May 9, 2010 Share Posted May 9, 2010 Hi This is Jerry, i already have a 2,2 carb engine in my 80 hatchbrat. It is a 96 imperza 2.2 and has a holley 4 barrel, it was at the subaru show last year. Thanks Jerry Link to comment Share on other sites More sharing options...

I'll get some photos of them next time I'm at the JY. Link to comment Share on other sites More sharing options...
LeoneTurbo Posted May 10, 2010 Share Posted May 10, 2010 Please note that the carbed and SPI EJ manifold will not fit the MPI EJ heads due to the bowls for the injectors (won't seal). Link to comment Share on other sites More sharing options...
LPGsuperchargedBrumby Posted May 10, 2010 Share Posted May 10, 2010 Please note that the carbed and SPI EJ manifold will not fit the MPI EJ heads due to the bowls for the injectors (won't seal). um....does that mean that the EJ18 carby manifold that is bolted on my EJ22 heads shouldn't be there?....as far as i know its only really differences in stroke length that mess with the ability to swap manifolds between engines of the same series....certainly on EJ series anyway Link to comment Share on other sites More sharing options...

I know of a local mechanic who regularly swaps MPFI SOHC EJ22's into Brumbies, with the carburetor manifold, and he has had no such problems. Also, I'm pretty sure when I stripped down my timing-belt-disaster of an engine DOHC N/A MPFI EJ20D (which manifold is very similar to the EJ22) it didn't have bowls.... Then again I was only stripping it for the alloy to sell for scrap, so I wasn't paying too much attention. Edited May 11, 2010 by rxleone Link to comment Share on other sites More sharing options...
LeoneTurbo Posted May 11, 2010 Share Posted May 11, 2010 MY89-93 EJ18 SPI gasket: MY89-98 EJ20/22 MPI gasket: It's not very clear from the pictures but the SPI and carb manifold/headport/gaskets are oval shaped, the MPI is also oval but with a nutch for the injector spray pattern. I believe that area will not be covered by the SPI or carb manifold. But I could be mistaken. Link to comment Share on other sites More sharing options...
bratsrus1 Posted May 11, 2010 Share Posted May 11, 2010 Hi This is Jerry, i used the stock intake on my 4 barrle carb set up. Where the injectors went in the manifold i removed them and put in soft plugs and where the coil pack sat on the manifold i cut a big square hole and welded on a 4 barrle plate.

Does anyone know what sort of CR I'd be looking at if I put EJ18 heads onto the EJ22 block? Link to comment Share on other sites More sharing options...

A bit higher but nothing the engine (ie.pistons) cannot handle. I think you will gain almost one point. Link to comment Share on other sites More sharing options...
rxleone Posted May 15, 2010 Author Share Posted May 15, 2010 A bit higher but nothing the engine (ie.pistons) cannot handle. I think you will gain almost one point. Like as is 9.5 to 9.6? I'm sure I could manage that might even bump the HP up one or two ponies Link to comment Share on other sites More sharing options...
LeoneTurbo Posted May 15, 2010 Share Posted May 15, 2010 More to say 10.5 I would have to calculate exactly how much but I have to dig out my Excel sheet with all the information on head volume etc. but I don't have it (yet) on my new company laptop.

LeoneTurbo Posted May 15, 2010 Share Posted May 15, 2010 Depends. I run a CR of 11.0 on my custom EJ22 DOHC engine and is runs w/o knock correction on the lowest grade fuel available in Europe (it's Euro 95, we also get Super 98 and even 100) but I don't know how that compares to US fuel. But since you'll be running a carb and a distributor you could always reduce timing by a degree or two to compensate. Or run a bit richer will also put you in a safe zone.

987687 Posted May 19, 2010 Share Posted May 19, 2010 We can't even get 95 at most US pumps. 87 is standard, and most states only go up to 93. I live in a state you can only get 91... Link to comment Share on other sites More sharing options...

WoodsWagon Posted May 21, 2010 Share Posted May 21, 2010 Yeah, but our octane numbering system is an average of two numbers, the reseach octane number and somthing else. So it might be hard to compare. Plus it's all crapped up with ethanol, doesn't smell like real gas anymore and corrodes everything. You have any progress finding manifolds and distributors in the junkyard? Last time I pm'd you you were still busy with a move or somethng so I let it lie.

Gloyale Posted May 22, 2010 Share Posted May 22, 2010 (edited) MY89-93 EJ18 SPI gasket: MY89-98 EJ20/22 MPI gasket: It's not very clear from the pictures but the SPI and carb manifold/headport/gaskets are oval shaped, the MPI is also oval but with a nutch for the injector spray pattern. I believe that area will not be covered by the SPI or carb manifold. But I could be mistaken. By my reading that's the same part #s for the intake gaskets on all EJ18's on the list. SPFI or MPFI 14035AA050 Superceeds to 14035AA051 which superceeds 14035AA190 Remember that just cause the PN's are different, doesn't mean it's not interchangable when you're dealing with subarus. I think if the same gasket works SPFI or MPFI on the 1.8, IDK why it wouldn't work a phase I SOHC 2.2? Same heads.

rxleone Posted May 23, 2010 Author Share Posted May 23, 2010 (edited) Okay, so the weather decided to clear up on Friday just as I was leaving work, so I got to the Junkyard on Saturday yay for me.. but unfortunately, the car I had been told was carbed was in fact SPFI, and the distributor had already been taken However, I did grab the SPFI intake manifold, which, as far as I know, is not the same as the carb manifold, but is close enough to build an adapter on to Here's some pics for you guys in the states.. Enjoy Sorry about the blurriness on some of the pics, camera seems to be playing up and don't know how to fix it... So, all in all, not a bad little find - I know there are some more SPFI cars floating around the JY's up here, so there's plenty more where that came from, and if worse comes to worse, and I can't find the original carb manifold, I'll just get an adapter plate for a Weber made up, and slot that bad boy on Edited May 23, 2010 by rxleone Link to comment Share on other sites More sharing options...
WoodsWagon Posted May 23, 2010 Share Posted May 23, 2010 Would you mind holding up an EJ22 intake manifold gasket lined up with the bolt holes on the manifold? It would be interesting to see the overlap on the gasket. I see what someone said about it potenially not sealing against a head with the injector bump in it. That looks like it could be pretty easily solved with a spacer plate, but then that brings in the problem of sealing the coolant crossover to the block. So mabe machine down the intake manifold mating surfaces the thickness of the block-off plate, and that way the plate is samwiched between the intake and the head, and the coolant crossover is properly clamped against the block.

I would, but I don't even have an EJ22 gasket on me at the moment mate. I think it could be easily solved, but as you said, seeing as there are no bolts clamping the crossover to the block, you could run into problems very fast. I think what I'm going to do is simply run the carbed or SPFI EJ18 heads on the EJ22 block. That way it raises the compression (which should bring power up, hopefully to nearly that of an EFI EJ22) and I won't have to mess about changing out distributors . Of course, that doesn't help those of you who live where there are only EFI heads. I'm pretty flat-out with work at the moment, so I doubt I'll be back at the junkyards till next weekend, but I'll keep everyone posted on the distributors and hopefully be able to grab a few manifolds.

Gloyale Posted May 23, 2010 Share Posted May 23, 2010 Weird, all our intakes over here are seperate from the coolant crossover. Link to comment Share on other sites More sharing options...
