Ok..so what can i do to an EA82

[EA82Loyale]

Ok,

 

i really don't have any clarification on this..

 

Just what exactly can i do to my engine...

 

Its not the turbo, just the plain version...(90hp)

 

Runs great, only 159,000 miles...so what would be a good "first mod"

 

I already hollowed out my cat, and strait piped it..it helped a little, but I didn't notice any major changes except it doesn't get as good of gas mileage now..(lol)

 

I'am really lost on this...if i can upgrade this engine, i would rather do that than take the EJ18..

 

By the way...the EJ18 I may still be getting is from the Wild Irish Racing Impreza. It was in with all the pictures on the site...

 

They are swaping for open class..

 

-Thanks,

 

Bill

Since you say you have 90hp, I assume you have the carbed version. You can put on a Weber 32/36, upgrade to SPFI, or go all out with a turbo. The stock engine just doesn't do all that much.

what are the stock HP of each engine?

the Na carbed

na -efi

and turbo?

[Snowman]

The SPFI EA82 is 90 hp, so this is a SPFI motor.

 

Carbed is 87 hp.

 

MPFI is 90-something.

 

Turbo is 115.

 

I've been told that cutting out the bottom of the airbox improves flow, but it might just make more noise. Do a full tune-up on it, get some better plug wires, maybe advance the timing a couple degrees.

Nope, tis a 93' fuel injected...

Well my friend has an EA81, the timing chain broke, and he says he will sell it to me. Its the turbo, and has all the nice stuff mine doesn't have like; a five speed tranny, 4WD, and air ride. But most importantly i want the turbo...will it swap over to mine easily??

For less than 100 bucks, you won't get much more than 5 horsepower, downhill, with a tail wind.

 

If you really want to go faster, i'd start with somthing with more than a 90 horsepower engine, in a race between a horse and a slug, which would you rather hotrod?

 

if you put some money (2-3 grand USD) and time into it you can get up to about 150 horsepower, but for the money spent on custom bits, you can get an adapter plate and your choice of EJ engines, with a cart full of bolt on go fast bits.

If your friend has the EA-81, first off, there is no timing chain, its gear to gear. second, its a step back, its a cam in block, not OHC, the ports are smaller, and if its anything like the USDM EA-81's if its a 5 speed its 2wd.

 

You'll need to do a complete wiring harness swap, which at that point, as i said in my previous post, get the EJ adapter plate, and an EJ engine, the EJ 18 has more power than the turbo, the EJ22 seems to be the most popular and over here has 135-145 horsepower, or an EJ25 160-170 horsepower.

I believe he's asking whether he can take all the turbo stuff, manifolds and whatnot, and swap it onto his EA82. First check if the turbo is water cooled, or an oil cooled one. the water cooled ones were installed as a recallish thingy and are better. It should have 4 hoses going to it instead of 2. The SPFI is a high compression moter, 9.5:1 I believe? This doesn't work well with turbos, and tends to cause detonation. But at low boost levels with premium gas, it should work. My advise? Take the snorkle off the airbox, its a pipe with lots of bends inside the quarter panel, and drive it like you stole it. If you're a convert from big displacement engines, you may need to learn to rev the c*ap out of it. You shouldn't drop below 2,000rpm's when shifting into the next gear.

A rally driver friend of mine is swapping engines out of his impreza 1.8 liter rally car. He has an engine, and tranny for me. I don't want to use the tranny in my car becuase its an automatic, and its weak. I've already replaced it once. How hard will it be to put in my car??

[NoahDL88]

Asking how hard it is to put in an EJ in an EA powered car is asking how hard is it to land a plane, for some people its an easy weekend job, for some its down right impossible, if you can change your own oil you're on the right track, if you know what a FSM and a DVOM is you should be able to figure out the wiring.

[Subarian]

It's something that's been done by a lot of board members. The question is how prepared are you to deal with the issues involved in an engine swap. You'll need to modify your wiring harness, fabricate or buy an adapter plate to fit your transmission, reroute cooling hoses, etc.
