What to buy when replacing fuel injectors?

[Surtr]

I am looking to replace my fuel injectors, but I am looking for advice on what to replace them with. I have a stock M20B25. I tried checking eBay for rebuilt injectors at a stock flow rate but could not find anything. I only see 19lbs injectors. My main concern with those is running too rich. I have seen differing opinions on them. Some people claim they will run too rich, some people say the ECU will adjust the duty cycle. I'm also afraid that the sellers on ebay have not really flow tested the injectors or even checked they are working. I guess my other options are to buy used stock injectors (where?) and send them out for cleaning, but that will likely cost more than the 19lbs injectors off eBay and they may not be flow matched.

So, would the 19lbs injectors be fine in my engine? Keep in mind I'm in CA and barely pass smog as it is (but I believe part of this may be due to shitty injectors). Does anybody know a reliable seller? Or should I try to get injectors with a stock flow rate? Is there a source of already cleaned, rebuilt, tested and matched stock injectors? Any help is appreciated.

Yeah, that's who I'd use if I bought stock injectors and who I used to base the price off of. Unfortunately I do not have the option of sending in my current injectors and having him send them back, as the car is my DD.

Check here, there are always people parting out cars. Should be able to find a set of injectors for fairly cheap. Then you can send them out to have them cleaned and tested.

Yeah, the problem with that is I might get a bad one and it'll end up costing more and take longer. I kinda feel fucked either way.

[Surtr]

Crap, does anybody know what is better? The yellow injectors with 4 holes, or the one with 1 hole and a ribbed pintle cap?

[dannyg]

On my convertible I just serviced the injectors and they had 1 hole with the ribbed pintle cap. I picked up a kit off ebay that had new caps, filters, o-rings and spacers. For a kit of 6 it was $24.

[Surtr]

Yeah, I looked at doing that too. The problem is one of my injectors is leaky and that doesn't ultrasonically clean and flow test them. I think I'm going to buy 19lbs injectors and if they suck ass or cause me to fail smog, I can at least use them until I can get my current injectors cleaned / replaced. But now there are 2 different types of 19lbs injectors to get.

Type 3's.

I couldn't find one! who was the seller?

[Surtr]

Oh wait, Design III is the type with 4 holes? I found some on ebay, hopefully from a good source.

The only other ones I see are from somebody named smokestackj and I seem to recall reading a post on here that his stuff sucked.

Heres a link to the sellers store:

Actually, I've read the 17.5lbs from an M50 are much better suited to a stock engine. You're better off getting those. Apparently 19lbs injectors only work well in cars that have vacuum leaks or upgraded intake.
