Hello guys, I was wondering if a computer was necessary for the 1999 4L v8 to run. Thanks

I would have thought yes for EFI and no for carb but I'm no expert.

Are you intending to use the injection system? if so, yes!

No fuel injection for me! Just good old carburetor

If this is a 4litre which succeeded the interim engine, with a serpentine belt drive it probably has the crank driven oil pump and no distributor drive. Ignition, i think, relied on engine speed sensors and the ECU to control it.

Sorry for reviving a dead thread but I just read a post on here from around 6 years back that says all I have to do is change the front of the engine and I’ll be able to add a distributer. Thanks for all the help!

You can still buy new timing covers from TA Performance if you can’t find a good used. You’ll also need the camshaft with distributor drive gear, much more choice on off the shelf cams with the distributor drive camshafts so not a bad thing.

Do you know what model I have have to use on their website ? I have heard 215 being tossed around, but I doubt that is applicable to my engine, and where would I get one of these distributer drive camshafts? Sorry if I’m being too... questiony, Thanks!

You may find it cheaper/easier to go buy a salvage yard 3.9. Its the same displacement motor, but with a distributor, and the appropriate front cover, cam, oil pump, everything you're going to need.

I actually just pulled the 4L out of a pull a part, do you think they would let me get away with the front cover or would I have to buy the entire engine?

Personally i would say that if you already have the 4.0 engine without a distributor there is no reason to think you need to sell it and obtain a 3.9. As an alternative to changing front covers you could go distributor less. A Megajolt or a Nodiz will entirely remove the need to have a distributor, is not very costly and is dead simple to install and adjust. My experience of using them on Pinto engines has been entirely positive.

The 4.0 has lighter pistons, longer rods, beefier crank, & cross bolted mains. It is a bit longer, but can be made to fit a B.

Would this require a computer? I am kind of dead set on not having one installed, not to sound like an ass or anything

Dumb question, sorry

No, it is not. Sure the path is easier to use a 3.9 with a dizzy, then add a carb. Not as easy, but that is also do-able on the 4.0.
