Bought an E30 a couple months ago, need some advice

[willfill]

So I just picked up my first BMW, an '87 325is. It's in really nice shape, but it has pretty loud injector tick. I was thinking of buying new injectors to deal with this and I read that it is one of the best ways to get more power out of an E30. From what I've read it seems that the Bosch 19# 4 pintle injectors are the way to go, but I wanted to know if there are better options out there, and if there are any other things I should do at the same time as switching the injectors. I've read that the miller maf kit is really good but I don't really have the money for it right now. So, any tips?

may not be the injector noise it could need a valve adjustment

You aren't going to get additional power out of the engine just by changing injectors if the ones in the engine now are working properly.

And as stated, adjust the valves.

Even if you get 19lb injectors the ECU will just will just cut down the amount of fuel. Without a tune of some kind they dont do much. If you do get a tune to let the injectors work well, you then need to make sure you can actually burn all that fuel.
Adjust valves. Tip: JP at A1 Auto here in San Rafael suggests using a 0.012in feeler gauge with a cold engine. Works well on my car. Give it a try.

you didn't say how many miles are on it but if its high mileage you may not be able to adjust the clack out of it, if the cam or eccentrics are worn.

I did the valve adjustment soon after buying, didn't change the sound. The engine was slightly warm though, so I guess I could try after cooling overnight. I changed the oil + filter as well, and the air and fuel filters. I ran some injector cleaner too but that did nothing. I used a mechanics stethoscope and the loudest part of the engine was the injectors, although a small tick could be heard when the stethoscope was placed on the valve cover. Car has just over 230,000 KM on it.

A slight tick from valves or injectors at idle is normal for an M20 engine, especially when the engine isn't at operating temperature, and is nothing to be concerned about.
