Default 2.2 mods done

I finally swapped my 2.2 in for the 1.8 yesterday. It is a long one day, one man job with good tools and a nice place to work.
Prior to swapping I cleaned up the 2.2's ports and had a good three angle valve job done. Shimmed the springs .030 and milled .008 off the heads. I had Delta cams regrind the cams. 285 at .050., I forget the lift. I used a thin head gasket, .023 to bump up the compression a little. To fix the camshaft timing I made a off set key at the crank too fix the right side cam. To adjust the left I made a "cammed bolt" placed it on the idler pully between the right and left heads. This allowed me to tighten the belt and advance that cam. I didn't use a degree wheel just lined it up with stock timing marks. I will go back and figuire a way to do that now that it is running.
I had to shim the HLA's, I made .022 shims to go in the rockers under the HLA's. This took up only part of what they took off the cam but there is a enough travel in the HLA's to make up the differance. I made shims useing spring steel washers that I found that had the right size OD. I Annealed them cut in the neccesary notches and slot then rehardened them.
There are more differences between the early 2.2 and 1.8 than you might expect. 2.2 has no egr valve, different throttle body etc.. I ended up plugging 3 or 4 vacuum lines .
Started it up, was a little nervous, a lot of custom stuff. I had a lot of noise from the valve train at first, I thought I had pumped all the air out of the HLA's but I guess I didn't because everything quieted down after ten minutes.
I have anouther Impreza with a stock 2.2 for comparison. There is no comparison, this engine pulls so much stronger, pulls hard 2000-4500 rpm, waiting for a hundred miles before I go to 6500. The engine idles rough and I had to turn up the idle to 1000 rpm. Have a CEL but havn't had time to diagnose it. My tumbler valve isn't hooked up, That is one of them.
Other engine mods, Borla headers, Stromung high flow cat and muffler. Light fly wheel.

Mad props to you. First build up of a 2.2l that I have read. What year was the 2.2l? After it has been broken in, please post a 1/4 mile time or dyno graph for us, pretty please.

No pictures, looks about the same as any other subaru, except no battery in the front, ac or charcoal canister. I don't think there is a dyno with in 200 miles of here. Maybe I could get some 0-60 times.

sounds similar to the spare 2.2 I'm dropping in soon.

Delta cams, decked heads, shims, lightened crank pulley.

Thumbs up

Sounds like a lot of thinking went into this project. Congratulations on your courage and your accomplishments.

Are the cams the difference in comparison of the stock 2.2 as far as performance goes? I don't know the lift/duration numbers that surround the stocker cams, but I'd suspect this where the extra juice is coming from .

Much Props

A few things I left out in my first post:
Manifold fitment: Between the head gaskets and the milling I took off about 0.1 inches total from both heads, The bolt holes still lined up, there is a lot of "slop" built in. You do need to match the runners though, I just used the gaskets to match.
Cleaning up the ports: A lot can be done there and it is not difficult. The valve seats and ports on one head where very close, lined up nicely, only a little grinding was needed to smooth it out. The second head was off quite a bit. I took out quite a bit of material to smooth the transition. The inside radius above all the valves has a very sharp ridge that is easily removed. Make the bends "D"shaped, flat side on the inside of the radius.
Many people think that engines with polished ports won't idle. I'm sure that carburated engines with long intake runners, v8's in particular, with radical cams that have no vacuume at idle have this problem. We can't run radical cams easily because of ECU problems. The Subaru engine is fuel injected. The injectors are only inches from the valve and that part of the runner is very hot. I wouldn't worry about it.
Things I would do differently next time:
I would use 1.8 heads. The're cheap, have roller cams, will bump up compression without having to change pistons, use thin head gaskets, or mill and no timing problems. (It may be more difficult to find a grind for the roller cams though).
When I had my valve job done I would have them mill the "top" of the head, the side the rockers sit on. Then you wouldn't have to mess with the PIA HLA's Take the same off the top of the head as the cam grinder takes off the bottom of the cam. The whole project would be much easier.
Regrind cams $135, Valve job plus milling $350-450, gaskets, fluids about $700
total. Could be competitive with a 2.5 swap, no DOHC head gasket worries, better ECU match, Emissions almost intact with fewer plugged vacuume lines.
