There's no such thing as an HPS lower intake, its a 1 piece casting. That looks to me like a Lightning lower with an adapter for the Cobra upper.
#6005
That could make for an intriguing combo as we are actually fighting so much stroke trying to get these motors to turn any kind of rpm, but thats getting to be a pretty expensive shortblock and if going high dollar I'd much rather have a big bore 4.6 with an aluminum block....
5.4 and destroker crank: cost of 5.4 + $1,000
4.6 FRPP 3.70 bore (5.0) cast iron block: cost = $2,000 for the block alone
4.6 FRPP 3.70 bore (FR500C 5.0 block) aluminum block: cost = $4,000 for the block alone
QUESTION---> How much do you want to spend and where's the happy middle ... (???)
#6006
bingo, we have a winner.....
#6007
You are correct, I was thinking of the topside not being removable, but the pic horspla2000 posted shows its functionaly a 1-piece design when on the motor.

Sorry to hear it r3d. pop in every once and a while so we know you're still alive.

I see what you're saying. Maybe we could look at it like this:
5.4 and destroker crank: cost of 5.4 + $1,000
4.6 FRPP 3.70 bore (5.0) cast iron block: cost = $2,000 for the block alone
4.6 FRPP 3.70 bore (FR500C 5.0 block) aluminum block: cost = $4,000 for the block alone

it's not. i must have quoted the wrong one. it's a lightning lower with a billet adapter to a cobra upper. plus a single blade tb should give me the air flow to make the engine happy with boost...
#6012
Ah R3D.......the quiter?
I now, have been building my car for 3 years! A hole in my stomach, a crap bag, and a $75,000 bill.......I'M KEEPING THE STANG! The SOB will rot untill better days!
Giving up so easily does not sound like you! What ....REALLY gives.

I've thought of that myself in the past, but I hope you plan on turning a lot of rpm to make up for the tradeoff in lost low/mid range torque... I think you'd need to be shifting around 6800-7000 to go faster with that intake.
#6014
Sorry to hear that R3d. Best of luck. Hopefully in the future you can finally finish what you started and have a beast car.
#6015
alright guys... I'm out.
Selling the car, done with mustangs. Personal reasons.
Tommy, please take care of the thread.

Sorry to hear you selling and giving up on your project. Hopefully something will inspire you to stay. You're like the God Father or the 5.4 swap. You have inspired me to do the swap. My only hold up is I have a Bullitt to build first, but a 5.4 FI project will be next on the bucket list.

with the twin 57mm hair dryers spinning i should be good higher up the rpm's

24# injectors in a 5.4
I got some 24# injectors to put in when I am finally able to put my engine in. Is the MAF calibration for these done with a custom tune?? Will it be ok to run without a tune while I am working the bugs out etc.?? Has anybody else done this?? I figured I better step up the injectors bec. I have ported heads, comp cams 270's, HPS intake, 75mm throttle body, C&L plenum, shorty headers, off road x-pipe and flowmasters. I didn't think leaving the 19's for this job would be a good idea.
#6021
The hairdryer's don't matter, the runner length needs to match the intended rpm range of the motor or you'll make less average power. The turbos will spool slower than with a longer runnered intake, and being as the main beauty of a turbo combo is that you can make a massive torque curve and go real fast without having to pull high rpm (much more reliable combo), so unless you are building and camming for a 4500-7000 rpm powerband I think you'd have a much faster car with an HPS intake over that setup. I know its a little late since you've got it, but something to keep in mind....
#6023
doh you!!!
Your a duech!!! lol i have this book man i would of sent it to you to read lol... **** ive known you for a few months lol... well hell never mind what she paid for it shipping and handling would cost now that i think of it... ok im a *****!! lol
#6026
I would rather adjust launch rpm or use throttle modulation to get moving vs giving up power in every gear to soften the launch. That big of a cam would still delay the onset of boost even with an HPS intake.
#6027
Red, you and illwil's black-sunshinel are the friggin reason i'm in the pot with this cursed car as it is... you owe use an explination! At least shoot me a PM or some explination..
#6028
ok ok.. i've skimmed through the SHM book, and i need more explination on overhead cam geometry and performance associated... can someone recommend a book? I've talked to some custom cam grinders and one told me that my cams must be indexed wrong to be having the problems i'm having...
#6029
true, but i'm alittle to far into it for going back to the HPS. I sold mine on here to help get another 5.4 on the road and this was the right price. i'll do my best with it and if it looks like it's killing me, i'll go back to the HPS.
#6030
It won't run poorly or anything, it'll just make less torque until I'd say 5k+ rpm is where the two curves would cross over.
