So, I really like the 05-07 V-10 exhaust manifolds and I think I can have the shop swap my 99 V10 for a 05 V-10. The 05 will be run by my 99 computer with a reflash. The electronic throttle will be mod'ed to my cable throttle and the variable intake and variable valves will be fixed in the middle of their range.

Any other forseen problems? I will be keeping my 4R100.

 

You doing all that just to get new exhaust manifolds?

 

Sounds like we jumped in mid-thought. Sounds like he is replacing '99 motor to a 05 v10 and had been deciding on weather or not to keep the original headers or replace them with the 05's.

 

Actually I noticed an 05' V10 on Ebay last night for less than a $1000, can't remember if theres a reserve or not but if I recall it had less than 10k miles on it and it came with the computer! just thought I'd mention it if anyone is interested.

 

I saw that one too, but I have come to my senses and am just going to port polish, and put new cams in my 99.

 

How you going to get a re-flash to run an '05 V10 with a 4R100 tranny?

How are you going to get a re-flash to run the '05 V10 without the electronic throttle? Isn't that part of the program?

It is also my understanding that the 3v V10's have a completely different electronic wiring harness...compared to the 2v. That includes all the anti-lock braking, air bags, dash gauges, etc. They are all now integrated in the '05+ V10 3v systems...and "speaking" or "talking" to the PCM.

Hey...if you can get it to work, then please post a tech article here at FTE! I am sure LOTS of folks would like to know how you did it. Good LUCK!

I was going to use my throttle cable and use the 99 computer to run the 3v engine. The variable valve timing would have to be disabled.

 

WHAT VVT ? the v10 anit got it. put a 3v in a older no way it will never run.

 

IMHO...if I had a '99 SD V10 2v...and wanted more power, then I would find an '02 or '03 V10 with PCM and install. Any modifications...would probably be minimal compared to the 3v version.

Again...not sure it could be done, but for the extra hp and torque the PI head gives...something to think about.

I thought that the V10 did not have VVT, but whatever the shop mostly works on 4.6's anyway.

Why would the 99 computer not be able to run it? If you hooked up all the sensors, put the 99 throttle body setup on it, etc.

It would get a retune for the better breathing 3v heads.

 

There is NO VVT in the 3-valve V10's.

To put a 3-valve V10 into a '99 is a MAJOR PAIN.

The 3-valve intake manifold is a split-plenum design, with a butterfly(?) valve in it that the computer opens and closes as load and RPM requires.

There is no way a 3-valve will ever run well with a 2-valve PCM.

The split intake is a MAJOR part of the 3-valve's power. Without a computer that can control that, you are going to take a MAJOR hit in power - to the tune of probably LESS than a stock 2-valve!!!!

Your best bet for more power is a 2-valve 2000-up motor WITH the PCM! Cheaper that way too.

 

If you replace the 99 non PI motor with a 01~04 2V V10 PI Motor, a well designed intake and exhaust system, 4.30:1 gears, 33 inch tires, and a good tuner, you can have 95% of the 3v V10 capability for a whole lot less grief

 

I am going to tune my 99 non-pi b/c it offers a lower compression ratio compared to the PI, which will be good for the twin turbos that are in the long term plan - along with a rebuild of the rotating assembly. For now I'm doing cams, valve job, port polish heads, remove broken exhaust studs, and probably replace the banks headers with ford racing ones, since they have a split flange design.

 

Really... hmmm, I didn't know that

I love this site!!

 

Finding an extra 35~45 HP out of the 99-04 2v Motors i snot too hard or expensive... the Ford guys left some to tinker with cheaply...the 3v V10 is gonna cost great gobs of cash to find the next 15~25HP that is still in there for a Normally Aspirated (NA) motor. This involves reducing parasitic drag and using a custom turner with lots of dyno time..and requires premium cost fuel... the intake and exhaust upgrades n the 3v V10 is where they got most of the new power...it is very hard to beat an already near perfect air flow through the 3v V10 motor set up.... The next level of power addition for this motor is a well designed blower or turbo system and redo of the internals to use the new air flow more effecinetly...My experience tells me about 425 HP is all this motor will make and still be a long term reliable tow haul machine
