I'm pretty sure you can keep the stock MPI system, but you need larger injectors. I think Mustang 5.0 injectors work.

Re: 4.7 stroker info

...do a search....
I built a stroker 4.5 this spring useing 258 crank and rods.
mine was a little different than your though because i have the OBDII system for EFI and you have the old RENIX system. I do know that folks built RENIX strokers ith good results.
heres a few links to keep you busy for about a year..

as far as performance, I built mine for straight torque and did i get it.. the engine runs well under 500 rpm and it never stalls offroad. my jeep gets 17mpg in town on 37" tires and will go as fast as i dare on the highway.\
it has noticeably more power than my wifes 2000 4.0 tj, but i dont have the numbers
let me know if theres nything else you need.

Re: 4.7 stroker info

The 93 does use an SBEC (single board engine controler) I am sure Chry started using this system in 91. Nice to see a reply from N.C. Where do you wheel at? Have you been to Uharrie national forest? Thanks for the reply. [img]images/graemlins/burnout.gif[/img]
