5.4 Swap... yea or nay

[redbird2289]

looking into doing a 5.4 swap into my 98 gt... what are some pros and cons? will i have to stay with a 2v or can i go to a 4v w/o changing computers and all that jazz? Where should i get a motor? junkyard and rebuild it or Jasper and dont worry about it?

[modular2valve]

the 5.4 2v swap is pretty much a direct bolt in with very little modifications, visit mustangboards.com and look into 4.6 tech and u will see a 260 page thread detailing the swap, the torque alone is worth it. the 4v swap gets a little tricky.

[redbird2289]

yeah forget the 4v crap. i am definitely 95% committed to doing this swap. but one thing i am confused about is whether or not i will have to get a different intake? and do you know what kind of hp/tq ratings i could get from a basic swap?

[modular2valve]

buy the hps intake thats specially made for the 5.4 2v swap. it takes the headache out out of things, u can buy adapters to run a pi intake on it but it's a bandaid. as far as power id check the site, alot of them have dyno sheets with basic builds to extreme

went to take the work truck to get an oil change today and while talking to the owner i noticed he had a 5.4 sittin in the shop... he said it had been seized up but didnt know how bad and GAVE it to me! i pick it up when i have time

[modular2valve]

sweet! that is definitely a start to a budget build

[SpectorV]

some wont clear the hood will they? which looks pretty bad

[redbird2289]

i think the fact they can make them fit under a factory hood is pretty cool but i think the cowl hood is great lookin to! especially when you need the extra space for your motor vs aesthetic purposes... but unfortunately i leave for the coast guard december 8th so it may be a year or so before all this is done but hey the $$ has to come from somewhere

[modular2valve]

the 2v will clear the hood. the only way it wont clear if they do a lightning swap. the 4v can clear it also.

[silverstangboy]

yesh, please do... if you go 4v and cant clear the hood just go aftermarket eh?

and I would think that a seized 5.4 wouldn't be too big of a deal, turned crank and rods and kick it. just resleeve any hosed up cylinders.

[redbird2289]

the 4v swap is more trouble than its worth from what i hear... i got the shop cleared out this eveing and will be gettin the motor tomorrow and hopefully it aint too too bad tho it has sat in the rain for a while... ill get started tearing it down and ill keep ya'll posted

[modular2valve]

im in the process of doing the 4v swap, its a little more involved but i want different. i think you will be pleased with the new found torque. do you know what year is the motor?

[redbird2289]

nope, when the fella told me i could have it i was a lil overwhelmed haha but when i pick it up today i have a few questions for him...

[modular2valve]

gotcha. just wanted to see what heads and intake it had, ie. non pi or pi.

[redbird2289]

it came out of a 06 f150 but it has no oil pan/ no intake/ and half the coils/ im sure its missing some other lil things here and there

[modular2valve]

it has the pi heads then, which give u a very nice start. ull need to reuse your oil pan anyway and i would use the hps intake. as far as the coils, u wont really need the as u can reuse your stock setup u have now.

[redcobravert]

if i were u i would look for a 4v 93 or 94 mark viii block i hear there solid blocks even better than the 03 cobras and u can find then in junk yards there acually one near me with one in it

[redbird2289]

i may do that but the thing is i got this one for free... and im tryin to keep it as cheap and easy as i can... if it turns out this motor wouldnt be a good investment im not out any $$ and ill start over no harm no foul

[redcobravert]

doesnt hurt to check the junk yards but like i said it might be worth it i cant imagine it being that much, theres a place 15 miles from me that has one its called U Pull R parts and i could check on it for u if u want

[redbird2289]

yeah man if ur ever over that way check on just how much it would be... im pretty curious now haha

[redcobravert]

i will check it out what kind of power are u trying to put down to the wheel? and what kind of cash can u spend i know u wanna do it cheap but u can get computers cheap depending on where u find them

[redbird2289]

i was wanting to end up with around 400 rwhp out of it but thats before i found out about the swap... but nothing too too radical and i really wont have any good money to spend till i get out of boot camp (ship out dec. 8th) so this build is gonna take a while and i really wasnt planning on starting it anytime soon but then i found that motor...

[redbird2289]

with this motor being a 3v motor and the one i have in my car being a 2v motor is there anything i have to change out?
