Yeah i definitely like the price of the Mahle Pistons w/ rings. They are about a $100 cheaper than what i have found.

 

I've updated the GP post with compression ratios for each dish volume.

If you grind out the swirl dam you can figure +2.5cc's chamber volume which will make the values each drop by about .3. I'm grinding out my swirl dam and polishing the chambers so I should end up with an even 10.5:1. I can run regular gas and an octane booster or 91 octane california crap gas on that.

 

Gotcha i changed my order to 11cc dish because i do plan on adding boost eventually.

 

While you have the heads off take a gander at grinding out the swirl fin. It'll unshroud the intake valve a little and help power (idle may get a little lumpier though).

 

I plan on getting the Patriot Stage 2 heads anyways so i shouldn't have to worry about that. I was going to try and pocket port my own heads but don't really have the time. and don't want to mess up perfectly good heads. Also wouldn't be as much of a power increase.

 

i used to work at Mahle. they are great pistons, but that is the weakest link in the terminators, and thats whats in the 03-04 is mahle. it is not the strength, its what the piston is made of. mahle is 2816 alloy or something like that, manley and probe is made of differant material. the good thing about the mahle peices is the special coating they put on the side skirts.

i would say, if you are gonna stay N/A and make power that way..go Mahle
if you wanna go forced induction over 550/550 go manley, cp, ross, diamond
mahle will stand detonation for a while, but that is the ultimate KILLER

********SUSCRIBE TO MODIFIED MUSTANG MAGAZINE**********

*******I have been talking to Hew Evans and Don Roy of Modified Mustang Mag. and they are gonna work w/me on a step-by-step installation of a 5.4 2V swap in my car!!!!!!!!!!!!!!
we are still working out the details, but it will be awsome for people who are curious about the swap. I suscribe to the other 2 big Mustang mags, and I have to say that Modified Mustang Mag. is prolly my favorite, awsome magazine!!!! suscribe to the mag and be ready for when the article's come out(<----2-3 differant article's) it should be out by the fall.*********

 

That's awesome!!!!!!! i'll have to suscribe to it, congrats.

 

The alloy you're speaking of is 2618 Aluminum which is the same as is commonly used by manley, probe, diamond, etc.. in most of their forged pistons. There are other alloys out there but I've never found one in wide enough use to trust it. I can't say that the pistons are the weak link but they're the most likely to fail due to their placement in the explosion room. I thnk that the rods and block are so overly strong that the pistons are the only thing that sees enough abusive forces to fail. The Manley rods are so unbelievably strong and the throw so short that it would take nuclear fuel to break them. The cranks are similarly overbuilt just liike the block.

how about a mention of r3dn3ck and the boys from Mustangboards that made this swap an idea that everyone could do and brought you all together? Gotta pimp dat' shizzle.

BTW... in October there's a big machine gun shoot in Kentucky. I'm hoping to drive out there with a buddy and take part. Anyone up for a 5.4 get-together then? Say around Covington/Cinci.

 

they already know of this thread, i put them on it a few weeks ago. i think they look at it from time to time. i have wanted a 5.4 2V in my car for about 3-4 yrs. just never have the ability, time or $$$...i am still short on 1 of those , i will let you guess which 1

 

I've bought that magazine before it is pretty good. i will definitely keep my eyes open for thats issue

 

well... I've got all of them to a point... tell them to come out and play with me. I'll get a credit card just to do that.. gettin my shizzle in t3h magz0rz is one of the primary goals for my car. I want to see it in a mag and know there are gear heads jaggin off to my motor.

 

HAHA Hell yeah i think everyone wants there car in a magazine.

 

yeah.. there's that certain pride when you know you've done a good enough job for others to look and say, "wow... that's pretty cool". Even if nobody ever says it to you, at least you know yourself that it was good enough to be noticed. I've put obscene amounts of time, money, blood (buckets of it), sweat and myself into the car to make it my dream car. A small spread in one of the rags would be kinda neat someday.

It'll probably be a few years before I get one though.

 

Oh yeah i feel the same way when someone tells me they love the way my car looks or sounds it makes me that much happier because of the time and money and effort that goes into making it the way you want it. I already got the body and stuff the way i want it minus the show finish paint job i want but that will be after i get all the mechanical stuff takin care of and then i will get that done and start sending my pics and story to the mags. But definitely a few years away. I had the money to do all that but it was either pay the car off or mod the crap out of it so i went with the smarter choice and paid off the car and saved money on all that interest.

 

Here's a question i already have a 85mm CnL MAF meter and once i get this motor done i was going to put bigger injectors in and i plan on having it dyno tuned. Currently i'm not using the MAF meter because it made my car run to rich. Yes i know that my stock meter is good for just your normal bolt ons but i didn't know until i already got it. SO i'm hoping i will finally be able to use it.

Would i have to get a different MAF meter or would it work?

Or would the stock injectors work from my mustang? 03 GT

What size injectors are good for what power ranges N/A?

 

I know the stock maf is good to like 400 HP, but the C&L will work, especially if you get the dyno tune.
I still think the injectors will be good with the 5.4, patriot heads and bolt ons since they are #21 (you know i have those), unless you get some sweet cams maybe then #24. and of course bigger when you get the Turbo set up. I know i read #19 are good to 300 HP to the crank after that you should go to #24, so #21 should be good to atleast 325 to the crank + or - some HP.
The key will be the dyno tune to get the most out of it but the #1 thing is having it run safely.
What about the SVT focus fuel pumps, i've heard about people putting those in their cars. i'm not sure how your stock ones flow. I know i swapped out my fuel pump for a 255 pump.

I know we talked about this yesterday but i thought i would post something and see what the responses are

 

Yeah i think i'm going to at least get some 24# injectors. I planned on at least replacing the one i got since they got 60,000 miles on them.

For those of you who might be thinking about upgrading your complete fuel system aeromotive has a complete kit for either the returnless style or return style. You can go to http://www.aeromotiveinc.com to read up on them. But i would search on line to actually buy them i found prices to be $200- $300 cheaper. The systems are expensive but if you want to do it right then theres an option for a complete kit.

 

the 21's in your current motor are sufficient to 350bhp or about 290rwhp. SVT focus pumps are t3h w1n. Cheap and super high flowing.

19's are what the 5.4's come with but if you're going bolt on or power adder, might as well keep the 21's or get 24's. You can just clean your 21's and they'll be super duper for use in the 5.4 and save you 200 bucks.

Below is my injector scale. There's actually a formula that you'd use but suffice it to say that these are not overkill or hard to tune but may be close to maxed out if you're at the higher side of the power output scale for each. You can usually just pick the next higher one if you plan on using nitrous or racing a lot/driving hard and you'll be ok. Don't overestimate your power and get too big an injector or it becomes hard to tune and drivability suffers.

<265rwhp 19's
<300rwhp 21's
<330rwhp 24's
<360rwhp 36's
~400rwhp 39's
>425rwhp 42's

In any case, stock pumps are azz. Replace it if you plan on making any more than stock power. The stock MAF is more and useful up to 400hp. The C&L is known to usually lean out a mix but that can vary. If you can get a tune to work well with it, then use it. You'll see some benefit at the top end. Not much, but a little.

Has 1.5 days left on it. 600 bucks for a turn key 5.4L. All you need is to slap on the RR plates and install it. It's in Maryland which should be fairly close to some of you. Don't chicken out... this is a KILLER deal.

BTW... not mine. Don't know the dude in all likelihood. Just saw the auction and thought about you guys.

 

Sweet deal!!!! NO one should pass this deal up. Funny how he's selling it cause it's to complicated to put into his mustang GT but he's putting in a 4.6 4V motor...i wonder if he knows it's reverse of that. probably selling it due to the intake issue and not knowing about the RR plates.

 

Thanks for the info. I'm hoping for between 330 and 360 rwhp so i will probably go witht the 36 pounders. I figured with ported and polished heads, cams, full exhaust, underdrive pulleys, HPS intake, and dyno tune i should be pushing that. We will see. I will be able to tell more after SaleenS330 gets his tune.

 

probably closer to low 300's... like 310-325. maybe more but plan conservatively. Still, 32's or 36's will be ok. And you be able to add some boost without getting new ones. Granted not much boost but some.

I'm planning on 325hp with 10.5:1 CR, xe262's or 268's, ported heads, and an intake but I'm also figuring on spinning 6200rpm to get there. Should see 400+tq though.

My rods shipped today. They should be here tomorrow or Monday. So stoked.

 

yeah i found a set of 30# injectors for $260 i think i will put those on my list.

That's sweeeet! Anymore takers on the pistons?

 

just me and you so far... see if you can drum up any interest in your local clubs

 

Only other person i know around here with a mustang is SaleenS330. I don't know of anybody back home either who is building a motor. I wish i did. Are you going to wait until we have 3 more or are you going to order after a certain period?

 

I'm hoping to wait till I have the 3 more peeps. Otherwise I have to pay full pop, and that makes me a sad panda. I'll give it till end of month, then I'll buy mine at retail. let's drum up the biz a little.

 

Come on guys we got like 7 other guys who are going to be doing the swap with in the next year or so you guys should jump on this. Once this catches on it might be harder to get what you need. Especially deals like this. Look at the fox body mustang if you find one of them in decent shape it will cost you more than what you can buy them for brand new. :helpsmili us out and yourself

 

I am putting in my order for the rods tomorrow. I can't jump on the pistons for at least a month. The guy I was gonna order my block from called me back and said he did some checking on the block and noticed a crack and didn't want to sell it to me. He is keeping an eye out for another 5.4 block.

I am gonna have to get a new motor soon. My 4.6 is burning oil now and smokes a little. I really really want this 5.4 and I want it now. Just have to do everything right and can't spend money every 2 weeks.

 

reply to the thread in the classifieds and maybe r3dn3ck can work something out. i told him i couldn't have the money until next month and he said it would work.

 

replied.... I am definitely in on it but like I said... The purchase has to wait for at least 3 weeks.
