Fuel Injector upgrade
I have the 87 xj 4.0 is the 703 the best injector to upgrade too? If not, what do you prefer?

703's are the ones you need for your 87. I just did the 784's in my 01 today. Under an hour start to finish. Well worth the money. Bought mine from 831xj in the for sale section under engines/tranny/t-case. I'm just west of you in The Colony.

For the older Renix motors, the 746 Volvo injectors are preferred.
