damn everyones been busy haha. its been awhile since ive checked in. a little update on my car: gettin taxes back in a week or so gonna buy some fr500s with 315s new nitto dr's. also gonna take get 30# injectors and get it tuned. gonna have a street tune and a n2o tune for a 150 shot of juice. also getting ready to pull my intake again and have it ceramic coated so it will have a chrome finish. was gonna hand polish it myself but got lazy haha.
do you guys think 30's and my stock fuel pump will be enough to support that much nitrous with a tune?
honestly ... no. I don't think that's a good idea myself. Even SVT Focus pumps start running out of steam after 425-450.
The 30's are fine with a wet kit and you'd never do 150 dry but you needum bigger fuel pump. I'm thinking 450rwhp worth of pump + a little to spare so, probably a aviator pump and you'll have a little room.

i never thought of ceramic coating! sounds like a real good idea cause getting things to shine cost major money these days. im in the process of trying to get my lightning blower polished i found this guy and he looks like he does outstanding work mirrorfinishpolishing.com he will even coat it so it doesnt oxidize, but ceramic sounds like a good idea!! im gonna have to check into that

Ya its gonna cost me around 80 bucks to have it done. Plus it will keep heat down.
R3d what size pump is the aviator? I might just drop in a 255lph just so I don't have to drop the tank in the future again when I get a blower. Would that be too much pump though for everyday use? And would it drop my mpg even more than it is?
if anyone is interested, i might fix and rebuild hunters 5.4 and have it up for sale. all forged with fox lake stage 2 ported heads and bigger valves. just tossing the idea out there. or i might sell the pieces off seperatly.
Hello swappers! its been awhile... well a quick update. I sold my heads, cams, and eaton setup. Had to make a few personal adjustsments. So I'm thinking maybe just some trickflows, cams, and hps with some shortys so I can just get it in and running? its simplafies a lot and makes it easier for me to complete. A strong 5.4 2v is really what I wanted to start with. And since I swapped out my nitto dr's and went to a smaller better handling tire its really made the entire cobra suspension swap worth it

Aviator is 310LPH IIRC. It's a bit more than a 255 and probably a better idea if you want a blower later. Not too much for DD use.

Thanks r3d! On the up side I will be having a garage to tinker around in again so. Things are looking up in the areas we had dicussed... on a side note if anyone has a 1st gen 4.6 2v. All aluminum intake they don't need id like to have one... and a stock lightning inlet? Thanks ya'll
Guys what did you do about your power steering res? maybe im just stupid but the front cover for the 96GT has provisions on it but the timing cover for my 4.6 doesnt?
i have to search for the pics i have but it is a basically stock 5.4 used the adapterplates for the intake untill i finish my supercharger design. Had the engine in two month ago but upon first fire up a ground bolt feel into the intake port and got sucked into the cumbustion chamber and put a hole in my piston so the engine got yanked out one new piston went it. Then my timing was off a little to much(was to anxious and screwed up to many times) and bent the valves. So this weekend i finnished installing my new head and runs great from 1000rpm up but i need to tune it bad. I was on a tight budget so my build was just a stock swap over but have alot of plans to come
so it seems to me that the consensus is 4.6 DOHC > 5.4 SOHC? I have a 99GT with a 99 Cobra engine in it now, 4.10s, full bolt ons. But I can pick up an 03 roller local for cheap. Thought about selling mine and building a 5.4. Worth it? Or just hang onto my car?
New to the forum. i have already did the 5.4 swap but i was wondering if anyone had a downloadable tune.
Need to know what injectors you're using, stock MAF?, cats/no cats, rear o2's on/off, desired fuel, TB size. If you're using the right bits then I may have an SCT tune I can forward you. It'll need a little finishing to be spot on but you'd probably be able to drive on it. It is a performance tune but not a very aggressive one.

The top one you can just see the PS res bracket. The cam position sensor is behind the res. The bottom pic is the 5.4 with the res in exactly the same spot.
If you hold your res where it was then you should have holes there. IF NOT, then relocate your battery to the trunk and bolt the res where the battery used to be. You'll need to get a couple generic PS fluid compatible hoses that are a bit longer than those that came on it but it's otherwise a fairly simple relocation. I bumped into that issue a bit with the lightning blower install (specifically the CAI).

Auto should be able to handle it but you have to have some respect for the thing and try to not break it by being excessive on the throttle at very low wheel speeds. Launches and burnouts are hard on trannies. Manual or auto, in an 03 you have about the same power handling capacity in either. I've seen a lot of 400hp blown gt's with autos live long and happy lives. One thing you most definitely want, is an auxiliary tranny fluid cooler. They can be had fairly cheaply from Hayden Auto or B&M or a millions others and are quite effective.

the whole this>that thing is really complete BS. Each motor has a purpose. 4v 4.6's are fun and capable of impressive hp numbers that eclipse what you'd expect from a PI headed 5.4 2v but those are peak numbers and accomplished primarily at high engine speeds. When you start looking at the averages of those runs against similarly constructed 5.4's you find that the 5.4 is seriously competitive with heavy ass cars like the SN95 chassis in that the tq curve is much broader. While a cammed ported head longtube NA cobra motor might peak at 340 tq the average is still less than 300. A cammed ported head longtube NA 5.4 2v is likely to peak at 330/360 with average tq over 300. Sure you shift at 5800 instead of 6500 but does it matter if you're winning?
Now that the TFS heads have had a chance to strut their stuff I don't think it'll be long before you see the first batch of really streetable 400rwhp NA 5.4 2v cars out there. Apart from that, 2v 5.4 is WAY cheaper than a 4v if you want to start getting into ported or aftermarket heads and cams. They're about on par as far as exhaust bits go but there's a massive aftermarket of 2v 4.6 parts which thanks to HPS you can still use.
I think I'd love a 4v 4.6 car for auto-x. But I'll take my 5.4 2v for any serious racing.
News on the car:
I tinkered around and re-wired the stuff I had in the back seat. I had all the relays and controllers and crap set up on a 18" square plastic sign to figure out all the cascading relays and adjusted all the wire sizes so they can handle the current going through them. It was kinda a huge ass rats nest since I used like 3' extra wire for each wire so the whole master board could be moved around the car. The extra has been removed and everything is in a secksy harness and routed under the carpet. It'll be partially concealed by the rear seat delete kit going back in but I've got to make a few modifications to it to clear the relays and controllers and battery box which are all where the rear seat used to be.
The progressive controller for the methanol kit worked beautifully when I powered up the electrical system and tested it. As I press more throttle it flows more juice. Neato. The IC pump is giving me fits but I think I've got it sussed. Just have to pull off some plumbing and switch em. Either that or it's not getting enough current.
To top it all off, I'm pretty sure the battery popped between cells when I tried to start the car. That's a bad sign. I did however get to the point that I added coolant and went to actually start the fucker up. So there.
BTW... does anyone have some sort of nice 1 gallon-ish tank. Something suitable for methanol so, not aluminum. It has to be either stainless steel or plastic. Somebody's gotta have a good tank. I have to mount it inside the cabin so it needs to be better than the gas can I'm using now.

its been a while since i have been on but im almost ready to build the forged out show motor!! i ordered 7qt oil pan high volume oil pickup tube to go with my mellings oil pump with billet gears, and got these new valve cover with custom engraved mustangs on them,now im gonna polish them to look like chrome!
I've got 21# injectors stock MAF, cats , 75mm throttle body, 93octane i just need a starting point i have a tweecer to fine tune it
I have a SCT tune for that combo but it's done in SCT software. PM me your email addy and I'll forward it. If you can use it, feel free. If you just need help banging out the tune in your tweecer, that's easy enough and I can help you find the scalars and tables that need changed. Basically, the only thing that really needs tinkered with is the displacement scalar and the MAF xfer function to clean up the idle and put extra fuel in it for WOT runs. You can add 10% to all the MAF counts above 500 and do the math for the displacement scalar. For timing I'd leave the stock timing curve and use 87 or 89 octane until you have time to get it on a dyno for a real tune.
You should also PM me your AIM or YIM handle. My aim is sditgf (splashdown in the gooey filling).
