Might seem like a dumb question...

I already have a EA82T in my 83 brumby, with the AWD 5 speed out of an RX, but i now feel i need something a little more...
I'm going to go the way of the EJ20 turbo. My question is this, What is the main difference between a 93-99 Impreza EJ20 turbo and a 91 legacy EJ20 single turbo.
It's just that looking around, you pay a fortune for a donor WRX, but a donor 91 legacy GT or RS is very cheap for a complete car. Does it come down to quad cam and DOHC?
What sort of HP can i look to get with mild mods out of a Legacy EJ20 Turbo, will it still be respectable?

The early engine will still be very respectable, they have good broad power, peak about 158Kw for the manual from factory from memory, and the auto about 10Kw less. Auto engines should have slightly higher compression and a slightly smaller turbo = better bottom end/less top end/more suited to auto box. Either can be modified the usual ways and everything has been done before so you can learn from others mistakes. And it will be good value for money, they are almost given away at DVA's.

Something else you might have an idea on, is often you can pick up the 90's turbo legacy's which are crash damaged, BUT this often means the cam belt has broken during the crash.
Is this a life threatening thing for these motors, or are they zero interferance motors and a replacement cam belt is all thats needed if you're lucky.

It does have a few cons:
-stock heads were very restrictive.
-Required aftermarket engine management(stand alone).
Today with the 2.5L STi block, the 2.2 is less desirable, considering guys are making good reliable power on them(on the 2.5 that is which people thought might not be possible when the block first appeared.). There are more engine management options available not requirering full stand alone management and the headaches that could arise from that. Also, the extra displacement allows for more power and more downlow grunt.
If you plan on doing a simple swap...stick with a stock wrx motor. If you wanna build something sick, go with either the 2.2T or the 2.5L sti. I myself prefer the 2.2L. Its of better construction and is more rare than the 2.5L. Thats just me though.

the turbo legacy's came with a closed deck 2.2L engine.
The EJ22T was only available in North America '91 to '94, all other Subie EJ turbo engines were 2.0L, and now the newer 2.5L. The early 2.0s were closed deck (tell '95 I think).

How hard is it going to be to get a ECU and loom? does a 2 litre ECU work?
I'm pretty happy to go with a basic after market ECU if i have to.
But i now want the EJ20T for my EA81 coupe, but i think i'll certainly be buying a complete car, so i can look to transfer running gear , gearbox / motor etc

I have a complete running NZ new EJ22 engine in a car here that im struggling to find a use for now i have 3 DOHC EJ20s.... do you want the electronics off that ? Im near Palmerston North. I think it would all fit in one box.
