Could you explain a little more in depth why that is? Shouldnt running a better/hotter/whatever you want to call it coil mean better overall preformance in the engine/ignition?
Well we are talking about a 74 hp motor so really it doesn't need a super hot spark to run well. Will an aftermarket coil produce a hotter spark. Yes. Will you actually be able to tell the difference. Probably not. I couldn't. Not to mention the quality of accel coils is crap. Mine didn't last more than a year before it blew out the pickup in my distributor. I swapped all back to stock and never had a coil related problem again.

Stick with the factory ones. If yours is getting tired see if you can find a stock replacement. I ran an accel super stock for awhile but its really not worth the money and there are zero gains to be had.

Had a whole reply typed and hit the wrong key and erased it. Blah. My exhaust was a custom y to a full catback. 2 inch from the head to the tailpipe. Solid lifters are fine you will just need to close down the valve lash settings slightly. Get permatoque headgaskets and be done with it.
I did some searching and found this video of my coupe from years ago. Exhaust sound clip
-
As for pictures of the exhaust you will have to pm beechbum (sp). His name is Dan and he is in Virginia beach. Not sure how often he makes it on here but he owns my old coupe.
-
I'm going to attempt to explain it and see if I succeed or not. Since the heads are shaved the rocker is now closer to the base circle of the cam. The pushrod length didn't change so when the cam comes around and moves the pushrod if is now pushing that rocker a tiny bit further than before (the amount you shaved the heads). For the lift to remain the same as it was you would need to shorten the pushrod the same amount that you shaved the heads.
-
The last motor I built I did the shaved heads with a five angle valve job and Weber carb. I did not touch the bottom end at all since it had 55k miles when I put it together. I also had a 2 inch stainless exhaust the whole way back. So to answer your question no you don't need to do anything more if you don't want to. You will get more lift from the cam with just the head shave. My old Subaru really moved well for having a stock grind cam. Surprised quit a few people.

Paul, how about Gen-2 hardtop rear windshield gaskets? Looks like I might be in the market for one of those shortly....
You talking about a ea81 coupe correct? Your going to have to do what I did and contact a place in Australia that I seem to remember being called Phils rotary and fast fours. Coupes are a different animal from all other ea81 vehicles.

Which is what I said a few posts ago lol. A hydro lifter acts the same and doesn't kno it's in a 74 hp Subaru or a 400 hp small block Chevy. Get it to zero and give it 1/4-1/2 turn more and lock it down and you will be golden

Here is another thread on the subject from last year. Id be curious to see what the whole procedure says to do in the FSM.
http://www.ultimatesubaru.org/forum/topic/155873-ea81-valve-adjustment-issues/
-
I'm the one what sent him the files he used to adjust the valve lash for the Hydro engine. Info is straight out of the FSM files.
He disturbed the Factory settings, and now has to "play around" with the adjustments.
If you replace heads, have them milled, what have you,,, you need to adjust the hydro lifters.
Well if thats what the FSM says then go by that but it doesn't make sense to me. A hydro lifter is a hydro lifter whether its in a EA81 subaru or a 400 hp small block chevy. They both operate on the same principle where there is a small spring inside and the oil pressure itself works to pump it up. If he is loosening the adjuster 1 1/4 turns from where the pushrod is just starting to be tight that says to me that it will make a ton of noise.
-
Make sure the fsm is telling you to do it for a hydro lifter motor and not a solid lifter motor. My guess is you are reading the procedure for the solid lifter motor. Those require a tiny bit of clearance where hydro motors do not. If you adjust a hydro lifter motor like a solid it will make a r.ton of noise. Last I heard the fsm does not go over hydro lifter adjustment because there should not be a need to in most instances. The method I described is exactly how to adjust hydro lifters on a small block Chevy or ford but there should be no reason at all why it would not work on a Subaru since the hydro lifter is acting the same in both instances.
-
There is a very good chance they are too loose if you are hearing tons of noise. Try a drive around the block and see if that fixes it. If not you will have to turn the motor over by hand until the valve you are trying to adjust is closed and do as follows.
-Back out until you get play in the pushrod
-Tighten until you just start to feel resistance turning the pushrod between your fingers
-tighten 1/4 of a turn more and lock down the adjuster making sure you are not tightening it more
- go around and repeat that for each valve and you should be good

Search on here somewhere. There are pictures of how I mounted 4x6 plate speakers in the stock locations. Took a bit of work on the drivers side but it was worth it.

Do a search of my old posts I kno I listed part numbers somewhere.

Post up a pic of your car but if memory serves yes these gaskets should fit your car.

Wow pretty jealous of that. When i had a EA81 subaru i was looking for one of those motors. I must have looked for three or 4 years on and off and never did come across one that was accessible to me. Good luck with it.
-
Found this sound clip of my former coupe. It is running a full stainless 2 inch exhaust from the heads all the way to the tailpipe. There is a high flow Cat on there as well. Muffler is a standard parts store Magnaflow. Its got a nice deep growl. Ask its new owner what he thinks .
-
Have you tried running it on the high way at high rpms (like 5k) so the cat heats up and clears out for about 15-20 minutes?
This^ My gf had a car that would fail because she refused to run it on the highway. It was only failing by a few points too....

Hesitation on first applying gas....sounds like a vacuum leak somewhere. Get a can of carb cleaner and start the car and start spraying around the motor. Your intake gaskets might be shot. You might have a torn line somewhere near the carb/distributor.
-
What are you idling at? If your idling at 750 or so kick it up to 800 or 850 with the idle adjust screw on the carb. See if that helps. Might also want to clean all your grounds and electrical contacts under the hood to make sure your getting all your voltage.

Well I bit the bullet and bought the Weber for $320. Also bought new plugs, wires, cap, and rotor while I'm at it. I should be getting the parts next week and let you all know how the install went. Here's a picture of her in Vermont.
You won't regret it. Just take your time tuning it and make sure the floats are set correctly. Mine were off right out of the box. Its pretty easy to adjust however.
-
Just out of curiosity, what was the temp when this happened? I had one the every time it got to about freezing it started choking out and I fought with it for 2 years until I figured out that the carb was icing at that temp. Check and see if your carb heat tube is installed and the vacuum switch is working correctly.
Mine had exactly the same symptoms as yours but as soon as I fixed that it went away.
He is having this problem now and its not cold enough yet to start icing carbs. I have had that issue once with the old hitachi however.

Ive gotten some camaro and subaru scores on ebay over the years and haven't got any bad things to say about it. Ive also made a good chunk of change on car parts. It just depends on who you buy from and if they are honest. I keep an eye on ebay for old EA81 parts and camaro part here and there.
-
No it will not work. Coupes and sedans have different size windshields and rear windows. You need 2 door coupe gaskets.
Ea81 hardtop coupe window gaskets.

If you had posted I would have sent you to a place in Australia as well. I had the same issue with my former coupe. Is this the one that the guy has been trying to sell for years on cl?
