Some guys on here are making some pretty amazing EA81 engine upgrades.
Plug some of the keywords into search here for good results.

After that, it's time to open up the engine - higher cam being the biggest benifit along with decked heads. The EA71 (1600) pistons will also increase the compression slightly. Everything together, can yeild around 150 HP or so.
The EA82 is a lot of work, and will only give you another 15 HP, and considerable complexity besides. Also has the disadvantage of requireing timing belt changes every 60k miles, and they have problems with cracking heads, and blowing head gaskets. Not a good choice for an off-roader.

1600 pistons, raises compression
deck heads .015, raises compression
1.70 intake 1.42 exhaust valves, more flow
Weber, more flow
Free flow custom exhaust, more flow
Delta Cam, more flow.
Disty recurve, more torque
Try some of that and you'll have more power than you can deal with.

i know that after i put on my new muffler my car doesnt stumble like it did, off throttle is alot better, and seems to run a little smoother.
i highly recomend getting a weber, exhaust, and a cam. and you should have plent of power, but if your like me and need more, then have the heads pocket ported, larger valves put in, shave them a few thousandth's, the 1.6lt or 1600cc pistons, port match the intake, and redo the dizzy for more bottom end torque and you should be good.

prolyl a good 10-15 hp
as an example.. my llifted hatch with those big 27's will flat out walk away from my stock 89' ea81 hatch.. i'm talkin a good 100 yards ahead of the stock hatch on an on ramp.. and thats starting out at the same time. lol
so you wanna figure how much power those big tires chew up, and its still faster.. its gotta be a decent amount of power gain.. really..

If so its nice to here from another EA81 owner in this area.If you want to do some off roading PM me and I could go there and have some fun. If you are not in Montana ignore everything past great.

I'm pretty sure that you can get away with running an aftermarket muffler as long as there is a muffler on there. That's what I was running until a few months ago and just changing out the muffler made a big difference in the high-end power. Yeah, our emissions regs suck here. I just hope I don't get caught:D .

I'm doin the same thing you are.. Screw the IM testing..
There are as many diesels up here as gas engine trucks and cars and they dont have to pass IM..
Why should we?
