Message As I'm sure you will learn, the "SEARCH" feature will quickly become your best friend. This topic has been covered ad nausem over the past several years.

That being said, anyone who responds to your above post will likely answer your question with another question: what are your goals for the car? Direct OEM replacements with no future plans of upgrades? Gobs of HP? Or moderate upgrades to enhance the thrill of driving it?

Whichever way you go there is one simple answer before deciding how big of injectors to get- upgrade to the new style (94+). If your '90 has original injectors it's a good bet they will not last much longer (Search will tell you this). Member Bernie(NoVA) sells a kit in classifieds with everything you need to swap to the newer injectors.

For the price of factory replacements you'd be better off going with upgraded (555/615-740cc) injectors, they will be more than enough to handle just about all of your power needs.

Second of all, are you sure it's the injectors causing it to run rough? It could be any number of things (Search will also reveal this). Research and test the suspect components before dropping $$$ on something that may not even be causing the problem.

Apologies for the long rambling response, i've been drinking.
