258 4.2L fuel injection conversion

[flatlandkayak]

I drive an 86 CJ7 with the AMC 258 i6 / 4.2l AMC 258 i6 / 4.2l motor. I am starting to rebuild it, and want to go fuel injected. There seems to be a variety of conversion kits available out there widely ranging in price. I want to stay with the AMC 258 i6 / 4.2l and convert it to FI. I would appreciate any recommendations, or advice you may be able to provide. I should also mention that it is a V-belt.

Check the misc section look at the "useful links I thought I'd share"
At the top of the page, I put several links and info there.
If your mechanically inclined just build it yourself for about $300 - $500.
I built mine and can answer most questions.

I'd recommend a wiring harness and chip from AFI affordable fuel injection, then pull and rebuild a throttlebody from a '90 chevy s-10 or s-10 blazer.
Buy misc sensors, electric fuel pump, o2 sensor bung and install if you don't have one already.

Hit me up if the links don' t provide enough info.

Since you have the engine out to rebuild it you could always junkyard a 4.0 head and MPFI
