Talking 96 Impreza L wagon questions

As you can see I have been a long time member
<------

I am about to get back into subaru land and purchase a 1996 impreza L wagon. I have been searching on here and other sites for answers to these questions with no, or little success. I previously had a 1991 legacy turbo that was massaged quite nicely, so engines I can handle.

1: whats the differences between the 97 and the 96 imprezas? I see on ebay and other sites that everything is offered on the 97-01 imprezas.

2: WRX brakes will fit, is it the spindles and axles too?

3: front end cosmetics, hood, bumper, etc, possible to upgrade to the RS big foglite, maybe JDM (i hate that term) WRX look, or is that MY97+?

4:?????

5: profit! (yes I spend too much time in TEH OT)

1. Pretty much cosmetics.

2. Yes, providing you have big enough wheels.

3. You can go a few different routes here. The '96 still had the 'round' headlights, so you can either go with an older JDM hood (if you want a scoop and vents) to fit that front end or change the lights and grill to the newer style and get an RS/OBS hood. As far as bumpers go, you can still fit an RS one or go JDM and get a Version 1-4 bumper (both have large driving lights).

4. ?????

5. Profit!11NINE

P.S. How's teh purpleone?

I have heard from teh poiple one twice since we split. Shes ok, i guess.

The car im getting has legacy GT (MY98) rims on it, 16 X 6.5 im hoping they are wide enough. Im not going to mess with anything until the mercedes is sold.

Im thinking im going to go the opposite was of others, brakes, suspension, cosmetics, then motor and trannie...

does anyone really have success with just turboing the phase 1 EJ22? Im not too keen on the whole USDM WRX swap process that I read from stimpy and his troubles, trials and tribulations.

I was thinknig of building a motor, and using an engine mgmt system, instead of an ECM and wiring nightmare. EJ22T short block, WRX heads, poof im all set!

Oh, my bad...didn't know you guys had split.

Those wheels's will be fine with WRX brakes.

I did/am doing mine suspension, brakes, cosmetics, motor/trans.

There are a few EJ22s that's have been turboed very successfully. Seach for subachad (he makes an uppipe that allows for a turbo to mate up with the factory 2.2 headers). The swap is not scary if you know what you're doing and are well prepared. An easier route (somewhat) which my friend's shop does is to swap out the whole dash/HVAC as well. So you have a new looking car inside as well as under the hood.

You can go the standalone route, which is more tuneable, but usually more costly. Also, it sucks for states like CA with strict emmissions testing.

not a problem, I diddn't publicize it, I have no malice agains't her at all. I just did not want OT jumping all over it, and then she would call me, etc, you get the eye-dear!

I just did not wanna screw with all the wiring hassle. Plus im thinking with microsquirt, it will give me endless tunability, whereas the WRX harness will again need a ECM piggyback.

the proublems stimpy and keeth for that matter are small comaired the the "not if but when" your turbo kit will blow up

good luck getting a mega squirt to work with a 6-1 crank sigmal

a 95 L wagon is a much better choice no obd-2 scans

The 96 has 2 less hp than the 97. The interior is also somewhat different. That's about it other than the hood/lights and grill as above. Possible that ABS was optional in 96 L's but was not in 97. EGR may be different too.
WAC has a page with his turbo experience on a 97. Seems if you do the engine management correctly and o-ring the heads it should work at 7psi for a good while.

ok, then maybe greddy emanage. But I would still rather build a motor, drop in a WRX or legacy turbo x-member, and do plumbing, wiring than that whole other debocle!

im great at turning wrenches, but wiring is not my game.... I can handle emanage, but OEM harnesses are another story...

The 2.2, with a bit of work, is capable of handling a lot of HP. You can throw together a turbo kit for less than $1500. Throw in a set of stock turbo pistons, run it at 12 psi, and have fun. Like someone said, look up subachad

HMMM, so I can grab a used up REGULAR 2.2, put in the rods and pistons, and it will handle it... hmmm

I wonder how hard it will be to get a used 2.2T I know how rare they are, used to have one :-)

NO. the ej22k, legT block is super solid. the ej22 NA is very reliable as is(does have the typical craptastic subaru head gasket issues).

Probally would be better if I cryo treated the block, etc then put in some forged parts... should be fine!

opinion on heads?

First off I believe the 1.8 already has forged rotating assembly (<-big fancy term for crank and rods for those who don't know) And I believe the 2.2 dose as well but not 100%. one of the biggest issues is the open deck (or is it semi open) though that only limits the big HP numbers. some lower compression pistons, possibly 2.2t. and a better head gasket would be a good bet. also a somewhat expensive option is closed deacking it. a good machine shop should be able to do this. As for heads, the WRX ones are nice if you can get them to fit, I hear they are not quite a perfect match. alot of cam options. and as for cryotreating, dose that work on Al?

If you want to play with the open deck EJ22E and turbo charge it, I have a suggestion. I have been playing with the idea for a while, but don't have a ginea pig yet to throw it in there car. Maybe when Diz or Bugman manage to blow up the hybrid engines I put in their cars.

Anyways, here's what I would do:
Take the Ej22E shortblock as it is, bone stock, and replace the heads with either EJ25 DOHC heads or WRX heads. Either route will require using the manifold for those particular heads, but will yield a very boost friendly 8.5 or less CR, depending on which heads you settle on. And using those manifolds makes it really easy to find injectors that will work with them for your application.

I figure it can handle 15-16psi, from something as large as a 16g and have you hitting the high 200's for power. If you go with a vf-10/11 or TD04 from one of the US cars, you are going to run out of air pretty quickly with the 2.2l of displacement and only see 240hp or so before you get out of their efficiency range.

Finding EJ22T blocks isn't that hard if you shop for a bit, and want to go that route instead. The last two that I have sold, I parted with for around $400 for the shortblock. That seems to be around the going rate.

Your other questions seem to be pretty well answered and the only thing I will add is that there is zero difference in the chassis from '93 all the way through '01. So when you are looking at brakes, suspension, body parts, etc. they will all work on your '96 chassis. Just some things, like a RS front bumper, for example, require changing headlights and hood at the same time...

well As i understand, the heads are not where the CR drop is made, at least not where the EJ22t is concerned. after much research and discussion on the SVX fourms (EJ33 is essentally EJ22+2cyl) they determened the EJ22t pistons are dished, thus lowering CR to about 8.5 or so. I am not certin but I believe the WRX is the same way. the best way to lower compression is to put EJ22t pistons in it. but even then I am not sure about 15-16psi on an open deck. besides for a street car all he would need is at max 9-10psi.

Well,
Your understanding of compression ratio is wrong. You can change your compression ratio by either changing your piston volume or by changing your cylinder head volume. The SVX guys are putting turbo pistons into their cars because they do not have access to a higher volume head that they can put onto their blocks.

Why do you think that when you mate WRX heads to an EJ22T block you get a compression ratio of 7.3:1? It is because WRX heads have a 45cc head volume while EJ22 heads have a 40cc head volume. It is a far simpler operation to switch out heads than pistons...

first off, you are correct. I stated that I was not certin if the WRX was the same way. The MY90 ej22 has 14.5cc pistons while the ej22t has 28cc pistons. the MY90 ej22 has a CR of ~9.5:1 while the ej22t has a CR of ~8.0:1,both have identical head volume. As far as head swaps go, the MY 00/01 ej25 will give a slightly lower CR than the WRX heads as they have a larger head vol of 50cc compared to 49cc on the WRX.

Also a MY90 EJ22 with ej22t pistons and the MY97 EJ22 heads and the SOHC gasket would yeald a CR of about 8.5:1 according to http://wac.addr.com/auto/obs/turbo/ejcalcs.html
I coulden't find info on the ej22 pistons with the ej20 or ej25 heads, I would imagane about 8.6. the page I mentioned has some good info on this.

But as I stated I don't think he neads to run more than 10 or so PSI on a 2.2l motor. much more and relibility will suffer.

Well I just picked it up and noticed something that I did not notice bofore RU fan and I stopped for lunch...

the front half shafts boots are split!

I know it would be easier to just throw money at it and put in new half shafts, but HAs anyone spent the time putting on new boots?

Noticed on the highway that the windsheild end of the hood vibrates at speed, and the plastic part under the wipers is broken...

The shifter is squeeky from 1-2nd gear.

sounds like normal wear and tear for a '96, though the hood thing bears invesitgation. perhaps weak hinges?

My 96 had two split boots as well.

Another difference is that the 96 is ODB 1 1/2 most sensors seem to be same as the OBD I cars.

Also, 96 has single output exhaust manafold.

Doing the RS body conversion is easy, I've done it twice on the same car now. Hood is the hard part to find cheap. Yout dont NEED to swap the lights and grill to get the hood bumper to fit. They just don't line up quite right. Only people that ever noticed on mine were Scooby guys.

Interior is obviously different. Power options are more prevelant. ABS is option on 96.
