Sixpackstang's Official Split Port Swap Post

[NMStang218]

yeah i dont remember what the problem was last time i posted but there was a bunch, the coil pack i resued was bad, somehow the plug wires were all backwards, and then it would run but not on its own. the #6 cylinder was just pouring so much gas in it couldnt burn which is what my old engine did, so i went and get a re-man computer and now it runs alot better. pete should be oever in the next few days to retune the chip and see how it goes

before i got the new computer there was so much unburned gas it somehow get into my oil, i drained my oil and it was pretty much all gas...i had it running today for a few minutes and pulled the #6 plug which finally had carbon deposits on it so the gas was burning, but i pulled the dipstick and it lightly smelled of gas...this is really starting to piss me off

Well glad to hear you resolved some problems Looks like Murphys law has been in full effect for you from the begining but looks like its letting up.
Maybe the dipstick still smelled from residual gas still being in the oil passeges. I say let it run for a bit and if the smell gets any stronger then look into it.

The only way I can see it going into you oil is by the piston ring. Maybe all that gas was just collecting in the #6 cylinder(since it wasnt firing) and when the car cooled down the ring contracted slightly from the lowering heat and the condensed gas dripped passed the ring. I had a buttload of antifreeze get into my oil this exact way. You said you had gas coming out the pipe right?

Which is the power lead and which are the ground leads and which ground lead corresponds to which coil (there's 3 coil packs in that brick). I'm going to try to go from a 94 coil pack to the 01 coil pack because it fits better.

take a meter to it and see which one is positive? I'm not certain but I believe the 3 ground wires are all the same color and the power is different.

Do you have a new connector that goes with the 01 coil pack?

yeah before swapping computers the #6 plug was just getting completly washed out and couldnt fire and it was shooting a **** ton of oil/gas/water out the tail pipes. hasnt done that yet but it does still puff a little white smoke and smell of a gas a bit. imgoing to compression test all the cylinders tomorrow and hopefully when pete comes over his retune should help alot

I found the information I was looking for here.

So far it is working fine.

So you said earlier that the 94-98s have two temp sensors on them and that a hole would need to be drilled on the split port lower to add the second temp sensor. Well, I was looking yesterday at my old lower and saw that it didnt have two temp sensors....just one...anybody else with a 98 have that??

If I remember there is only one sensor that plugs directly into the intake. Look on the coolant tube that comes out of the front of the intake, the other one is plugged into that a couple inches up.

yeah ones in the side of the bleed port if i remember correctly then the others in the lower intake

i didnt use the one in the bleed port thingy because that one just sends the temp to the gauge cluster, the other one gives the reading for the computer

ya im an idiot, disregard my existance on that last post.

Okay, I'm fully aware that this thread is as dead as a doornail, forgive me.

I found this back when I was first planning my split port swap, and seeing as how my split port engine had it's throttle bracket removed, I ordered a new one per the part # on this post, F4SZ-9728-B.

Turns out that guy is the throttle bracket for single port engines and it won't fit on the 99+ upper intakes.

A week, a few headaches, and a lot of time getting to know the guys at the ford dealership, I got the right bracket. If you ask for a bracket for a '00 3.8L, they're gonna order you a single port bracket. It doesn't fit, the ford listing is wrong, I did this twice before I asked them to look ahead a few years, at a 2002 3.8L. Sure enough it was my bracket.

Cliff Notes: The correct throttle cable bracket for a split port engine is 1R3Z-9728-AA

Again, this is a dead thread, but I referenced it and I'm sure others do too when they hit 'search', don't want anyone else getting lost like I did.

i just made a metal plate so that the single port thorttle cable metal bracket could mount to the split port upper intake then used an 01 (my engine is a 99) throttle body because it took alot less modification to get the throttle cable hooked into the TB

Hey - I am wondering about the fuel rail thing - I am going to put a 4.2 out of an f150. I am fairly sure that it has a RETURN type fuel rail - would this not work for the 94-98?

It will work if you use an F150 upper intake manifold. The F150 upper will not clear the stock 94-98 Mustang hood, however. The 99+ Mustang upper intake manifold clears the stock 94-98 hood but it will hit the f150 fuel rail.

What he said. The only other way I've heard of getting the F150 rail to work with the mustang intake is by putting in at least a 3/4 inch intake spacer. But don't quote me on that, just what I've heard. Also, I don't know about hood clearance issues with the spacer either, but I don't think its a problem.

And to the guy saying this thread is dead as a doornail, no worries man! I think its stupid how everyone always tell people to use the search, but when they do and they bring up an old thread they yell at them for that. Its perfectly ok for a technical discussion like this!

this thread is the only reason i was able to even get my car running, so **** people who say search, this should be a sticky

i think from what ive heard 3/4" spacer you just have to remove the hood liner, but dont quote me on that.

 

[RoughRidin232]

I got a 9/16ths spacer, so I'm crossing my fingers on this...

 

[sand1303]

anyone heard from sixpack lately his last post was sometime last year. i wanted to get some info from him

 

[sircrashalot]

anyone have the video to do this?

 

[sand1303]

i have looked for it before with no luck. v6sprout is the one that started it and he doesn't have a copy anymore if you find one of decent quality let me know

 

[drkhorse]

bringing this back since it hasnt been updated in a very long time. ive read countless pages on split port swaps,and have yet to find a step by step guide to doing it,nor are there 100% answers to some of my questions. i have a 1995 mustang,it has an auto trans, i want to put a 1999 complete motor into it( the one in it is blown) my main concerns are the wiring changes and what will i have to do to attach that 99 motor to my 95 auto trans? and depending on who you ask the parts list needed will change every other post, maybe its just me but there doesnt seem to be solid guide on how to do this,not to piss off the op there is alot of good info here,it just seems sloppy.
