98 ranger to 97 ex 5.0, final few questions

77'cj7 · Oct 23, 2009

Tomorrow I am picking up a 97.5 explorer with the gtp 5.0. I have a 98 ranger supercab xlt with the 4.0. I have spent quite a few hours reading about this swap, and have a few questions remaining.

I plan to use the x engine and transmission, along with the current manual shift 1354 t-case and 99 explorer rear axle in the truck.

I have the 9" AA transmission to t-case adapter, is this the right one?

What is the easiest way to hook up the VSS?

Will the 97 x computer work with the 99+ fuel rails, or should I run the return line and replace the regulator?
If the rails will work, are the injectors the same?

Thanks,
Chris

I believe the 5" Advance Adapter is a closer fit but it still does not match the factory t-case position. Either 5" or 9" adapter will probably require driveshaft mods. Those 2 adapters were originally designed for the AOD and Advance lists a conversion kit for output shaft oiling that must be added for AODE/4R70W. (P/N 716057) Ford AOD Shaft Conversion

The factory 98 Ranger VSS setup will continue to operate the speedometer without modification.

The 97 computer will not work properly with the 99~01 returnless system. For best results, these parts should be a matched set:
PCM/Fuel pump/regulator/lines/rails/injectors/engine harness/trans harness/cam position sensor/synchronizer.

96~98 uses 19# injectors at 30~40 PSI return fuel
99~01 uses 17# injectors at 65 PSI returnless

Another issue: Ford made mechanical and wiring changes to the 4R70W between 98 and 99. The PCM needs to match the transmission too.

Thanks!

Sounds like i get to run some fuel line and pull the reg apart.

Guess i'll see if i can make the 9" adaptor work, i got it on ebay several years ago for alot cheaper than new. Was aware of the oiling kit, ordered it yesterday.

I see you're running a supercharged 5.0. What blower kit are you using, and how much did it help?

For now i'm trying to do a super cheap swap, but future plans include torque monster headers and a nice solid rebuild on the block, along with a 6psi blower.

Only power mod for now will be exhaust system, custom with high flow cats and a dual in single out flowmaster super 40.

Any other recomendations/general bits of advice?

Thanks,
Chris

It's a Ford SVO Motorsports kit (simply a rebadged Powerdyne) designed for the Explorer V8. Out of production for a long time now. These have a reputation for burning bearings and breaking cogbelts - I'm working on fixes for those potential problems now although mine has given me no trouble. Also, the conversion kit includes mickey mouse fixed tensioners for the front end accessory drive belt and blower belt. This might be acceptable on the short blower belt but is stupid and ineffective on the 6 foot plus FEAD belt. Lots of cold slippage and requires too much static tension that still only partially stops the cold belt squeal. I made up a new stronger blower bracket with mounts for factory spring tensioners and hopefully that will stop the noise.

I'm totally guessing but I would think the supercharger is good for about 50 HP on a stock engine. It's centrifugal so most of that gain is midrange and top end. The engine is getting rebuilt right now with several changes that should take better advantage of the blower.

Here's the kit setup the way it came from SVO/Powerdyne.

Thanks again.

Blower kit sounds like a PITA, little much custom work for my tastes.
Did this kit come with a chip? From what i've read, it sounds like the ex computer will compensate for a reasonable amount of boost with no problems, fuel pump just needs an upgrade.

Speaking of fuel pump, I'm also installing a secondary tank, and it would be easiest if i could use a inline fuel pump, with feeder pumps at each tank. Would a fixed 40psi work, instead of the variable vacuum regulated system?

If you don't mind me copying, whats the high output intake badge off of? Looks awesome, and seems fitting with the addition of a blower

Also, i'm trying not to rip into the ex too much. Ive owned it three days, and am already kinda attached to it. Way to nice and solid of a vehicle to kill, so i'm gonna try to drop my 4.0 ohv back into it.

The Powerdyne/SVO kit came with a FMU (fuel management unit which is a boost controlled pressure regulator that pushes the FP higher than stock) plus a secondary high pressure fuel pump. A seriously goofy arrangement that was probably used so the kit could retain the factory PCM and still get Powerdyne an emission exemption. I threw that BS away after messing with it for awhile. I ended up using 19# injectors instead of the stock 17's and tweaked the PCM calibration with Sniper.

On the 96~98, the fuel pressure is regulated at the rail by controlling the flow rate in the return line. The stock PCM is set up for that and you shouldn't need to give it up. Any EFI pump you use is likely to be capable of way more than 40 PSI max. The regulator cuts it back to what the injectors want to see.

The intake plaque was used on several years of 5.0 Mustangs. You may be able to find one on eBay for about $30~40.
