Question Turbo Charging my 1.8L

Like everyone here know's by now, I have a 93 Impreza L and I'm wondering if I could find a turbo charger for it? Plus do anyone know who makes one and where I can check out a website on it?

Thanks,
Andre

i could get you a WRX engine and tranny(240hp model) and a Haltech ECU, exhaust, and you're off!! This would be much more durable, this way. The tranny you have is pretty much garbage if you are going to turbo it. They are way smaller that the WRX or 2.5rs tranny.

Try a used stock WRX turbo and stick it on there with some custom work...

You're pretty much going to have to custom fabricate everything for it.

You could use any kit from a 2.5RS. Just about everything is the same, so a Minnam or some other kit would bolt on.

Another option is to make your own kit. And maybe check out the following link...

So about the transmission, Why is it weak?? My 93 Has been turbo'd for about 40,000 miles now and the only problem I have is the syncro going into 2nd. I did that before the turbo.

The 1.8 tranny is weak compared to the 2.5 trannys. Being smaller, the gears and shafts can't be as big as a 2.5 tranny. My 2.5 tranny has a 4 puck clutch, with instant engage, and have had no problem. That's no problem running 20psi on the street.
I wouldn't say the 1.8 wouldn't last a long time, because that depends on how you drive it and how much HP you have.
If your budget can't support the 2.5 tranny or something else, then i would stick with the 1.8 tranny till it breaks.

Jeff,

Did you get the 4 puck from Paul? I bought one from him too when I was in Tigard, but it didn't fit because I actually have the FWD clutch on my car. Subaru even gave me the wrong parts when I replaced the clutch.

There is one other factor to consider. My little clutch will slip before the tranny breaks, so as long as I stick to a weak clutch it's more likely to give than the tranny. It's a stinky mess if I drag race, but I'd rather replace a $300 clutch than a transmission.

How many people have grenaded thier trannies with the stock clutch? Not many. The way I see it, when accellerating hard something has to give. With AWD, it's not usually the tires. With a weak clutch, it will slip. With a really "good" clutch, the transmission and drive lines are the next in line to get the abuse.

Are you really running 20 PSI??? I want to see this, can I check your car out when I'm there for Thanksgiving?

P.S. I'll be moving back to Portland, most likely Sherwood in Feb.

No i got my clutch from Lee Shadbolt, he lives a couple of miles from Paul. But it is the same clutch.
your point is good about the weak clutch slipping to provide the "dampening" to the tranny. But as i experienced, the stock clutch began to slip very soon.
It was like a new car when i got the 4 puck clutch.
Let me know when you get to tigard again.

I think know where Lee lives, or where he did live anyway. Off Tigard street and that road that goes to the school and has a "Jacked up" intersection that finally got a light.

I think when it comes time to do the clutch again, I'll go with a stock pressure plate, 4 puck, and lightened flywheel.

Default tranny size

Jeff -

Help me out here. Are you sure the 1.8 tranny is smaller that the 2.5? Or even the WRX, Legacy, etc.? I don't know, thats why I am asking, but when I installed an EJ20 into my 93, the tranny from the 1.8 would have fit exactly the same as the Legacy AWD I did use. If it had been AWD instead of FWD, I would have used the original. Maybe the internals are sized differently? Or perhaps more advanced metalergy for same size?

But I don't see an actual size difference. Am I wrong?

For my money, I would replace the 1.8. Dollar cost for a used EJ20 already turbo built will be comparable to putting a turbo on the 1.8. BTW, if you need a spare 1.8, I have one in excellant condition for sale!

I too have a spare 1.8. My 1.8 4wd tranny is smaller than the 2.5 tranny i put in the car, but they all bolt in the same.
All EJ motors and EJ trannys bolt to each other, so yes your would have fit.

My '96 1.8L tranny is holding up fine w/the EJ22T motor I put in. I have an ACT pressure plate from a friends '98 and a WRX/RS clutch disk. My 1-2 syncro is going, but that was started before the motor went in. As long as you don't abuse your car the tranny will last you a long while.

Scoobyslack, What flywheel do you have? I have the smaller FWD one even though my car is AWD. Appearantly I have one of the first AWD imprezas or something...

How much would a custom fab turbo kit for a 1.8L cost vs. throwing in an old turbo Legacy engine? I may be selling my old crappy car soon and hope to use the money to mess around with my Impreza.

How Much???

Here's a quick run down of what I have and the cost. Remember this is to run 5psi, if you want more then fuel management becomes even more important.

Turbo off XT: $45
Machine work on turbo to get the outlet to 2": $60
Gasket set from Carparts.com for the turbo: $25
oil feed line from autocaresubaru.com: $30
oil return line: $50 (used some earls #12 fittings and tapped into my pan)
Complete exhaust: $400 @mieneke (it sucked and I just redid it)
I Used my Weapon-R for the intake going into the turbo
Intake tube between turbo and throttle body: initially this was about $200, but now that I can weld I can do it for about $50

OK, that was the initial kit. Now I have a new 2" up pipe I made and a 2.5" downpipe that will go into a 3" exhuast and cat with a Borla muffler.

>Replaced the stock wastegate with a Deltagate since the stock one sets boost too high at 10psi.
>I pick up my SFC which is REALLY needed today
>I now have an intercooler off a SAAB (about $80 on Ebay)
>I still need a Walbro fuel pump and Cartech RRFPR to get some more power out of it
>I bought a hood scoop that I'm still waiting on shipping

I keep updating my site with more info, the only problem is the site is down for the week. On another note I'm now making custom up and down pipes. PM me for more details.
