hi, I know there is a lot of info on what injectors to use for a stroker on the site, so excuse what seems to be a common question. I am getting ready to install my 4.6 stroker (going by the calculator I am at 9.2scr/7.9 dcr) in a 1998 xj with obd2. I have a '99 intake and was planning to run the banks header and would like to see what size injectors would be the best fit for my engine without spending a lot of money experimenting with several sizes. I also was having thoughts on going to a larger throttle body , but don't know if I would get any advantage out of doing so. Thanks to all who can give some feed back, Dave.

the stock tb tapers down a few mm so most people tend to get it bored to a true 60mm. that way no buttery fly valve is needed (aka less costly). there are other bores out there but most will say to stay within 60-62mm tb to stay streetable. with 62+ mm will make it a tad touchy from what most report.
for ev1 injectors bosch 0280155715 OR mustang blue top ford 24#
for ev3 injectors bosch 0280155784 - i believe silverxj is presently running them

I would recommend either the Mopar 53032704AB from a 04-06 Jeep 4.7L HO. They are 4 hole and flow about 25 lb. Or the Neon 0-280-155-784 Injector, which flows about the same is is also a 4 hole design.I am currently running the Neon injectors.
