injected v.s. carburated

I think all the later 2.9l's I've come across had the MAF sensor. So I had just assumed when the EGR vlave and larger throttle body were no longer used for 88 and later that, that was because of the new MAF system.

I have yet to see in person a 2.9 with a MAF. I don't doubt that there are some out there, but all of the non-egr equipped ones I've seen are speed density.

The MAF equipped 2.9s are the CARB compliant ones. Very odd to come across one outside Cali.

so how much do you think it would run me to do a 4.0 engine swap

 

[adsm08]

4 to 500 for a donor truck and then the cost of what ever tools you'd need that you don't have. Grand to 1500 total probably.

hmm, mabey i should hit up my local pick and pull for the parts needed for MAF convert before i move...

My 4.0 conversion cost around 200 dollars. new gaskets, water pump, stuff like that. i already had the donor.

1000 dollars wouldn't be out of the question. Just make sure to have plenty of extensions and a good floor jack. Well worth it.

Yea, I'd say the typical 4.0L swap will run around $1,000-1,500. There's lots of little things that you don't think about till things are tore apart. Or that you think about but don't expect - like figuring on the radiator being good and you get it in and find that it didn't leak before but it leaks now.

 

[adsm08]

I'm expecting my swap to run more like 3000 to 3500, but I plan to buy a donor truck and then turn the engine in as a core on a reman, so I'm expecting that to be in the area of 2000 alone.

alright cool thanks guys ill look into it and get to work. ill keep posting along the way.

If you're looking for more power the MAF conversion isn't what you are looking for, it does, however make the power that is already there, more usable. I was having issues with my speed density 2.9 a couple of years back, I converted to MAF and never looked back. I found that the engine will lug down much further before stalling and the throttle response and fuel mileage is MUCH better.

As far as 4.0 swaps in a first gen ranger/b2, it seems like it wouldn't be too hard to do with a good wiring diagram for both setups. I was thinking about it a couple of years back and found that if you have done the MAF conversion you are already halfway there. The TFI and EDIS systems use the same pins on the EEC, and after that it would be down to rerouting/ extending wiring and a couple of other small changes. The reason I haven't done it is because I have some strange attachment to my 2.9, yeah it's a gutless wonder but it gets decent mileage and will motivate my truck to a top speed of about 70 without too much issue.
