has any one out there ever take the stock 14lb injectors and replace them with the 19lb injectors from a 5.0? the car in question is a 1987 2.3 with a very ported head assembly which seems to run way to lean in high rpm which is where it is during racing in the scca.

The stock 14 lb injectors are maxed out at I think 150hp. So if your pushing that or more, you may need a set of 19lbers. Also, you will need the MAF sensor that is matched for the GT's 19lb injectors. I believe the sensor should be a tab bit newer like off a 94-95 GT but it's been a long time. Here is a link to a guy whos done this before at the bottom and races a 93 LX 2.3L DIS I believe. If you deside to go this way, let me know because I got a MAF and 19lb injectors around here somewheres.

Thats right, they didn't go to MAF until the DIS 2.3Ls. I've never messed with SD cars so I'm not really sure on that one. I know the MAF sensors are calibrated for the injectors they are using and I'm guessing the MAP sensors are the same.

Sounds good

So did you just use the 19lb injectors and nothing else?

I'll have to keep that in mind next time someone ask about them with a SD.
