ea82 swapping long blocks


Recommended Posts

okay heres the deall and i have to have made my dissision by tonight jan 12....

 

i'm looking have baught an 86 5speed d/r wagon with a blown hg. no big deal

 

what i'm thinking is that if i buy (for an unfairly low price) and 88 carbed 2wd wagon i can swap the long blocks without issue and end up with a running car.

 

thoughts and warnings?

I just did a swap from a 91 Ea82 into my 86 ea 82 carbed wagon and all i had to do is put the carb/intake and disty onto the 91 block and it runs great except for my carb is on its way out. When the carb was good i could take it up to allmost 7000 rpms with no problem and get over 30 mpg. The 91 has more compression so its got a little more horeses and torque. Have fun everything should just bolt on. It took me 5 hours to do a total swap up and running.

The long blocks are virtually identical. Should just have swap on your intake mani, disty, exhaust mani, and all the accessories.

 

While the long block is out of the car though, you may want to reseal it so it doesn't leak oil. At least the oil pan and the rear main seal as those are a royal PITA to do with the engine in the car.

 

Canada got 88 Carbs? In the US, all 88 EA82s were SPFI (SPFI long block will swap into a carb too).

got the first of the two cars dropped off today. yea me!!! i think i'm actually keeping a running tally on this one. all prices are circumstantial and in canadian funds.

 

so...so far, 86 white 5-speed d/r wagon with sunroof and rust in familiar places. oh and blown hg and 256000km --- $160

 

cost of tow + dolly charge (i said it was a soobie so they got me a flat deck:rolleyes: ) --- $130

 

so far:

 

car 160

tow 130

total to date 290

 

i think i'm doing good so far

That is a good swap, nothing should be changing. there is a second thought about what subaru freakishly (I have said it yet again about the ea82 and thier differences) did to 2wd and 4wd, spfi and carb. The spfi even though higher compression has delayed cams on the intake side and open sooner on the exhaust (they really attempted to kill the benefit of 9.5:1) for the very outdated slow ecu for it- faster ecu can have nice tight cams for a full stroke like the old carbs have. The carb is actually the winner in the hp/torque department.. in fact after 8 years and on my 9th with a carb ea82, it may very well be underrated. You had a good question, alot of folks don't pay attention to a half tooth timing off by oem, or the fact that cams change throughout some models. there is an informative thread here about that someplace...What you have in mind should be exact swaps, again except for the second thoughts I have about 2wd and 4wd carb differences ,I haven't found anything written, maybe an old soob pro mechanic can answer that question with the thorough fsm.:)

I bet you can do it for under $500! :grin:

Actually, the facts you propose are extremely flawed. I, as well as a handful of others have used SPFI cams on carbed motors creating more HP and torque throughout the powerband. Get the facts before you add information that you think is correct.

 

Factory torque and HP specs will argue that fact as well. Higher rating in both catagories for the SPFI.

picked up the last of the two cars today, this one is an 88 5-speed front drive with throttle body injection (tbi). this car has 182000km and i paid...ready for this, $60 for it. the cause: the car has a windshield that has fractured and separated from the seal (and the car) and the body has decided to become like Swiss cheese.

 

rather than do anything with the car. i'm taking the long block from the tbi car and converting it for use with a carb...and no, i'm not going to argue this one. it will be a carb and i'm not dealing with the wiring harness issues

 

moving on

 

86 wagon 160

88 wagon 60

tow 130

reg and day pass 56

 

total to date 406

General reference, SPFI stands for Single Point.. as opposed to MPFI, Multi Point.. alternatively, you can refer to them as throttle body injection, or tuned port injection..

 

Search the forum using the name Gerenal Disorder for EFI swap, or just swap.. he has done a wonderful write-up on how easy it is to switch the FI to an ea-81, and switching a carb'ed ea-82 to efi would be even simpler...

 

Sorry, I had to say it. If you have not read GD's write-up on the swap yet, give it a skim.... because it really is not difficult, and it REALLY is worth it. the SPFI system, when all sensors are functioning properly, works like a top, every time, no matter what the atmospheric conditions are.. AND all the components are individually verifiable, using a multimeter and sometimes an assistant. I only make the point to beg you to consider the option before the other car gets hauled off... you sound like you want to run the carb engine FIRST, at the very least. However, this FI system (unlike many) is much much more simple than any carb, and the FSM is more than enough to "train" you for it.

perhaps i'm miss understanding. the cams are the same?

 

because throttle body injection (tbi) is not the same as sequential port fuel injection (spfi)

Someone should really have a post of acronyms we use.

SPFI = Single Point Fuel Injection

So SPFI is another way of saying TBI.

(C'mon, sequential injection? They weren't advanced enough in the 80s for that :lol:)

my point isn't one of performance, but of usabuility. the computer and sensors (all but the co2) are all water logged from sitting around too long.

 

to me its just not worth messing with something that i already have years of experience with. ofcourse it would be different if everything already worked as it should but it doesn't...and i'm almost out of cash.

On Subaru's they are. The SPFI on Subaru's is Single Point Fuel Injection

They only other setup is MPFI and that only came on the turbo's.

 

Almost correct, MPFI came in the 85 2wd GL10's and XT's, without the turbo.

okay update: this weekend i got the block into the car and the carb and distributor on the car and fired it up. it ran smooth as whipped butter. i was very surprised.

 

it wont be till i get some other parts before i can shake it down but from the looks of it so far i will be meeting my $500 budget on this car. however the vacuum advance on the distributor is looking a little elusive so wait and see on that one.
