yellow tops are 19lbs. They're stock for all 96-01 GT's and are enough to drive around town but they're going to get at or too near 100% duty cycle on ya. You need at least 24's and I'd really use 30's. Remember, the 5.4 needs more fuel in the same cycle time as the 4.6 so it's not just about lbs/hr.

www.Hiperformancesolutions.com has your intake. They're the only ones you can get one from. Hurry, they sell out FAST! Last I knew he only had a couple left.

 

99stangswap5.4 - pm me i have about 5 sets of injectors from 24's up to 80's for your car.

deathdesiel - the j-mod and a good tq converter will wake up the auto. i have a dirtydog tq that made sleepingGT's 5.4 go apeshiz at the track. pm if interested.

 

Drove the stang to work again today. Damn I'm gunna miss that car.

 

no you won't, you'll end up keeping it and loving it everyday you drive her...

 

I have the same feeling after driving my car and its enough to keep the for sale sign off the windshield. Maybe I will break mine out today.

 

I just finished browsing through this thread and I must say it is very informative. I have a quiestion though...

Is there a positive displacement supercharger that will fit in a new edge 5.4 2v mustang with ANY after market streetable hood??? Not talking about a 20" cowl hood.

 

yes, tork tech (TTI) makes a really very nice kit for it. Look in the last 10 pages and you'll see one of the guys with said setup. You should be able to work that under a stock or very small cowl hood.

Note to self, positive displacement on a 5.4 makes for a wheel spinning tire fryer.

Hope that helps.

Well the Tork Tech does seem tempting and as you stated I would be purchasing tires every week... But could Kenne Bell or Whipple fit just as easy?? The Tork Tech simple using adapter plates to accomodate a 4.6 blower on a 5.4, but could an actual aftermarket 5.4 blower fit with a streetable hood?? Or could a 4.6 Kenne Bell or Whipple fit on a 5.4 with fabricated adapter plates??

Sorry for a million questions, I am just very intrigued...

 

Update on mine....Got me a set of 24lbers and some new brakes. Now all I need to do is get a free weekend to install it all.....But the good news is it runs.....

 

Sorta. Lemme' splain'... the basic problem with all the 5.4 specific blower kits except the TTI is that the blower snout is up really high (see video below of a whipple'd 5.4 mustang on the dyno) while being pretty far forward. The hood ends up with a pulley sticking through it or you have to use a cowl with a nasty fast ramp rate. Those hoods are made but they tend to be race oriented (lift off). Finding a tip-up hood that ramps fast enough will be your challenge. Not saying it's impossible but it'll take some research and possibly a hood or two that doesn't clear being returned. I had a hard time with that before I decided to put it back to NA.

The plates TTI uses are more like runners and not really adapter plates as we're used to seeing them, they don't add angles to the airflow. You could think of their kit as a purpose built 5.4 blower that happens to share many parts in common to their 4.6 blower kit if that makes any sense. It seems from their design that they intended on making the 5.4 model available from the start but didn't want to have 2 castings and they came up with the best implementation yet.

A 4.6 KB or whipple would fit with regular off the shelf adapter plates (that might clear a stock hood, maybe). That's going to suffer the problems native to existing adapter plates such as coolant leaks and the ever present fuel delivery and airflow gripes. The TTI is really the best single solution. They have an option for you to use a 03 cobra compressor IIRC, may save a little cash that way.

EDIT: Congrats Nater! Grab up some pics and vids man.

 

The problem with the few 5.4 2V kits is that their made for the trucks and require a pretty tall hood. The plus side to the tork tech kit is the bolt pattern on the lower manifold where the charger mates to it, is the same pattern as the 03-04 cobra's. This gives a TT owner the choice to pick any cobra aftermarket blower. Now as far as fitting under a streetable hood, I'm running the standard M112 blower on my 5.4 with a 03 cobra hood and still had to do a little triming. If you upgrade to a KB or whipple a taller hood or k-member spacers would be required.

You wouldn't want to use the older style spacers to retro a 4.6 KB or Whipple to a 5.4. Tork tech would cost a little more but be alot less headaches and better air flow.

 

Here are some updates for everyone and some pics. I am really close to having this done other than the rotating assembly and flywheel/clutch and some other little things. I did pick up a set of trick flow heads and stage 3.5 MHS n/a cams. They will be here next week. I also have my block at the machine shop being bored .030 over and cleaned up.

5.4 ****!!!!!!!!

 

Hey, I'm Kyle. R3dn3ck informed me of this thread on the corral, and told me to post up my questions. I have a 96 GT with the infamous cracked intake, and I am looking at my upgrade options that are available. I'm really interested in a 5.4 2V, and I hope I can get some answers that will put me in the junkyards looking for a 5.4 block. My ultimate goals are 400ish RWHP. Is this achievable with 10:5/11 to 1 compression, TFS heads, hardball'r and cams? The car is not my DD, but I would like if it was some what street-able since it will be about 90% street and 10% track driven. If this is possible, how would I be able to identify a PI 5.4 engine in a junkyard? I would like a PI engine since it will be in the car for about a year or so untill I can begin my "all out" build. I know of the 5.4 tags on the valve covers, and that PI will be stamped on the heads, but are there any production numbers cast into the block, or certain year trucks/vans that would be better to look for? I'm new to this idea, and I hope I haven't shown my noobieness to bad, but I really need and appriciate your help with this.

 

kyle: to hit 400rwhp you'll need longtubes and you might want those heads ported to keep the cam somewhat sane but yes it's totally possible.

Below on the rear cylinders in the valley there's a boss jutting out off the cylinders but the bores continue above that boss.


On a 4.6 that boss is all the way at the top of the cylinder bank.


You'll also notice that the passenger side cylinder bank is visibly taller on a 5.4 than on a 4.6. Apart from casting numbers, them's the best visual methods. Also, I've only ever seen the style of valley ribbing on that pic of the 5.4 above on 5.4's. Never seen it on a 4.6. 4.6 ribs are almost flush with the block as shown in the pic below:

r3dn3ck.. will you tell me what all year of the 5.4 will work.. the one i bought was messed up.. i found a brand new 2007 5.4 engine w 100k mile warranty... but idk if it will work.. and also, what year/model of a flywheel do i need to buy for it to work?

 

Not that this is something I'm considering, but for the 4v guys using adapter plates, could you not bolt an 03 cobra lower to that and run an 03 cobra blower setup be it eaton, whipple, KB? Again not something I would be planning on doing right now, just a thought for the future if I ever get bored with being n/a.

 

travis: you're wanting a 97-03 motor. The 2007 is the new 3v setup. Flywheel, you'll need to see if you already have an 8-bolt. Some 99's do. If so, change nothing. If you have a 6 bolt on it, then a 10.5" 8 bolt will work. Usually advertised as being for 2000 GT's.

Jarryd: yes.

 

redneck.. i just looked into getting another motor, i found one, but it doesnt have any intake on it, what all options do i have? im looking for the cheapest route for now

 

You couldn't use any intake that comes on a 5.4 anyway. You can use a PI mustang intake (any stock or aftermarket PI mustang intake) on $375 Reichard adapter plates which is a cheap but problem prone solution (One of the guys probably has a set of MMR plates for sale). There's also the HPS intake, the ONLY other option and the right one. It's 700 bucks and you'd better get on the horn to Bob because you really want one. He makes fairly small batches that sell out fast and it can be a while between batches.

The hps 5.4 Hardball'r intake fits under a stock hood and bolts up just like stock. It's designed for the 5.4 and won't cork your motor like a regular stock plastic PI intake.

Adapter plates leak. Coolant leaks, vacuum leaks. They never line up just right. The leaking isn't even the big bummer part. The angle they throw into the air flow is really sharp and messes up the air and fuel delivery. With plates the injector sprays the bottom of the intake runner instead of the back of a closed intake valve like it should. So you end up having to put a ton more fuel into the tune than should be necessary. Let me be totally clear, get the HPS intake (www.hiperformancesolutions.com) or be pissed off that you blew cash on plates.

Get some 24 or 30lbs injectors too. I have a lightning 90mm MAF I'll let you have for 20 bucks + shipping which should help as well (your tuner will appreciate it)

You'll want at least a 70mm TB. I like 75mm. For a CAI, you want something with a big pipe. JLT and Spectre both make kits that'll do. LMK when you're fixin'a order those and I'll point out some deals.

FYI, some aftermarket 4.6 intakes like the Fox Lake P-51 and Reichard will not fit under a stock hood anyway, so on plates it's an inch worse.

 

Lol, Why didn't you offer me that lightning maf?

I hope my internals come in soon, I'm getting antsy and want to get the engine together.

Aside from that, I pulled the cams off my heads today and those heads need work. One of them appeared to have something sandy inside one of the lines in it that coolant runs through. I'm going to have to make sure they're cleaned thoroughly before I install them.

Anybody want a set of stock navi cams? :/
I've also got a 2v timing cover and a few other 2v parts that I don't need anymore.

 

r3d: Any word on the bracket for centrifugal superchargers?

So im dropping off the parts for the assembly of my 5.4. Current parts list is with a few of them im waiting for them to come in:

5.4 block bored 20 over, Manley pistons, H beam rods, Forged crank, Trick Flow heads, CMS cams, MMR windage tray and oil pan, CPR rails, Cobra tank with twin GT Pumps.

What I still have left to decide on is centrifugal or positive displacement supercharger and long tube or shorty headers.

I like PD superchargers but am realizing that I will have absolutely no grip so centrifugal would seem like an option and retain the street characteristics but still support my power goal (around 600 rwhp) But what size centrifugal?

Headers seems like an obvious option and I seriously want long tubes but their availability isnt there and I cant see spending the money for custom or waiting for them to get made to build the car. I have BBK equal length shorties and an o/r X pipe so can go to long tubes when someone makes them available.


So my real question for everyone is what is you opinion, Tork Tech TVS or centrifugal (if a bracket is available)

 

if you want it, it's yours. didn't know you needed it.

I'm working on the centrifugal bracket for vortech blowers. I'm not sure but it looks like all the big name centri's use the same bolt pattern so it might work just as well for prochargers and paxtons. That could be as long as several months. It could be really soon too. I need to get the god damned CAD work done but I've got a lot of irons in the fire so I'm stretched thin. Stanger00 was super cool and lent me his spare bracket, so at least we're getting somewhere.

Centri will make big peak dyno numbers and sound really impressive. Roots is a tire frying machine and has fantastic response to throttle angle changes. With your combo you'll end up staring 500rwhp in the face at a fairly modest boost level with either. I've attached a couple sims to illustrate the differences. Everything is the same except the type of blower. You'll see a drop with the centri between 2k-3k as it spools up.

Your BBK pipes won't fit. Sell them and get JBA's if you want shorties. I'd just call up FTP and slap some cash down and he'll start making you a set. This idea that you can order everything off the intarwebz without ever speaking to someone is ludicrous. Call FTP, get your longtubes.

I'd run the TVS setup (get the intercooled model if you seriously want 600rwhp) in your place. You'll have a much more powerful car overall even if the peak numbers on the dyno are higher wtih the centrifugal.

I hope you got the CMS stage 3 cam. If not, send em back. You'll need the bigger cam to reach your goal. You'll also be needing about 18psi either way. The power under the curve with the TVS blower is going to be unreal. You will probably want 3.27's in the back. And you're going to need to do something about the tranny. I'm thinking TKO 600 and a twin disc clutch. At near 900btq you're also going to need to make sure you have those tq box reinforcements welded in and beef up the rear end. 31 spline or a currie Ford-9" upgrade.

Have you considered all the wonderfulness that a direct port nitrous kit would bring instead of a blower? You'd have your peak power at the flip of a switch (and then a press of the pedal) but you could turn it off when you don't need it and not have to deal with it at all.

 

Just got off the phone with Bob at HPS. Looks like we'll be making some brackets. They're going to be a small run part and machined, not cast so it won't be super cheap but it'll fit.

I need someone that has access to more than 1 year of 2v front cover (and any 3v and 4v covers you can access) to make an outline of the covers on butcher paper and mail that to me. Volunteers? This will help get the brackets set up so they mount in a good spot regardless of the year of your front cover. And if we're lucky we might be able to make a bracket that fits 3v and 4v's too.

Anyone with a centri on their 5.4 is hereby commanded to post pics showing close ups of the bracket where possible.

 

I'm not positive what MAF I need. I know the stock one isn't going to be near big enough, think that one is too big?

 

if you're NA a LMAF is a good idea. If you're blown/turbo'd then you'll probably want a SCT 2400 or 2800 if you're taking the boost up very far.

 

I'm running n/a with spray on occasion so the lmaf is probably the best choice. I can pick that up from you, I've got 20 bucks. Let me know how to pay you and I'll get that to you.

 

I'm debating throwing out the idea of a 4v and buying some tfs heads and running those with the typical HPS intake. I would be able to save myself a lot of headaches but I'd be giving up a little power that could be made up somewhere else I suppose.

Can somebody convince me to either stick with my current plan or sway my decision one way or the other. Maybe post some n/a 5.4 TFS headed numbers to compare with. I know what my setup is capable and if I feel like I can make myself happy with a 2v setup, I may just have to go back. Everything from cams to valvesprings to porting will be cheaper.

 

ok on the shorties, was hesitant on FTP as their site has been down for a while, got the BBK shorties and Xpipe cheap so no loss there

Nitrous is going to be an option if I cant get the numbers im shooting for

I know with the power on the TVS will be monster on low end but im hoping that it would be tame enough on low end to at least get moving (going for drag radials on the rear anyways) and not have to go that low on the gears I like how the car seems with 3.73s but know that adding 400 rwhp will change alot.

Tranny should be strong enough, I have a T-56 Viper spec. I think that it should be close to holding it as long as im careful on the drag launches.

Cams are on hold right now will be ordering as soon as the shop gets a chance to go through my parts.

Rear end is already on the list, looking at moser 31 spline axles with a ford racing torsen diff. Torque reinforcements and bracing is on the way.

Im building the engine for the power but will probably keep the boost a little lower till I get everything worked out on how its going to hold up.
