ya so im jsut brainstorming what FORD v8 conversion would i put in a 1999 ranger ext cab 4x4 with a 3.0? just thinking about it and how much money would it cost me est?
The easiest V8 donor for a 99~00 Ranger 4x4 swap would be the 99~2001 Explorer/Mountaineer 5.0 AWD.
The entire 5.0 engine/trans/AWD transfer case from the Ex bolts directly into a 4x4 Ranger using the Ranger mounting points and original driveshafts. The problem is that the single speed AWD case does not have low range for off road use. There is also a reduction in acceleration, fuel economy and tire life on the street with the full time AWD case.
To keep the current part time, 2-speed 4x4, an adapter kit is available from Advance Adapters that will mate the 4R70W trans from the 5.0 Ex to the original Ranger Borg Warner 1354 t-case. Getting the correct length adapter (there are three) should allow the factory Ranger driveshafts to be reused. The Advance kit costs $500+.
Many other 2-speed transfer cases will bolt directly to the 4R70W without using an adapter. A couple of readily available cases are the BW1356 and the BW4406 from full size Ford trucks. They are heavier duty cases than the 1354 but are also much larger and more work to squeeze into a Ranger. Plan on custom driveshafts for these cases.
Check to be sure that you have an 8.8" rear axle. Ford doesn't use the lighter duty 7.5" behind the 4.0L, so you shouldn't use one behind a 5.0, especially in a 4x4.
The 99~01 Ex fuel system is mechanical returnless and runs at 65 PSI just like a 98+ Ranger. Earlier Ex engines run at a lower pressure and either the truck or the engine would need fuel system mods to make them compatible.
The factory Ex 5.0 manifolds and down pipes fit in a 98+ Ranger without modification but will need some custom exhaust work from there back. The only off-the-shelf 5.0 tube headers that will work on a 5.0 in a 98+ Ranger are those from Ford Racing (out of production) or Torque Monster ($600~700). The factory manifolds are very restrictive - I would opt for the TM headers especially if there are any plans for other performance mods to the 5.0.
Electrically, a swap would require the complete engine, trans and start/charge harnesses and the PCM from the Ex donor. It is mostly plug and play under the hood but there are a couple of minor wiring changes to get the Explorer harnesses to work with the Ranger body harness. In the interior, one wire needs to be moved in the cluster plugs to make the factory Ranger tach read V8 RPM correctly.
The 99~01 Ex PATS is 100% compatible with a 99~00 V6 Ranger. If the Ex PATS module and keys are also transplanted to the Ranger, they should work immediately with the Ex PCM. If the original Ranger PATS module and keys are reused with the Ex PCM, a dealer would have to "introduce" the new parts to each other before the engine could start.
99~2001 Ex uses the same type of speedometer system as the 98~00 Ranger - no mods needed.
The high pressure power steering hose, the AC hose manifold, throttle, cruise and transmission cables and many other odds and ends from the Ex donor are needed to complete the swap. IMO, the best way is to look for a deal on a complete crashed/rolled Ex donor, use what's needed and then sell off the leftovers after the swap is complete.
Cost could vary widely depending on what kind of deals you can get and how much of the work you can do yourself. Here's a good rule of thumb for late model engine swaps: whatever budget you calculate up front, plan on it costing double before it's all over.
All things considered, 98~2000 Rangers are the easiest year range for an Ex 5.0 swap with 99~00 4x4 V6's being the easiest within that group. So, from that perspective, you have a very good place to start.
