Going Turbo LS or Turbo 4v stock motor.....info inside.

What 8U said. It was a tired old hulk that he saved even the engine will go someplace better than what the last owner thought. I like creativeness. Heck if the price was right I'd put a Furd motor in my Chevy just to get people talking!

^ I had seen that in a news ticker on Facebook!

And no worries guys, all opinions are welcome! I can see both sides of the argument.

Indeed, this car was destined for the crusher when I got ahold of it. I paid $1800 for it as it sat on the dealer lot, whom which had it destined for whole sale to the scrap yard as per the salesman. I was informed of the car via friends that work at the dealer. Previous owner didn't want to put any money into the car and traded it. Upon getting it to my shop, I found that the LH bank had low/uneven compression, further diagnosis revealed a broken LH secondary timing chain (which SOMEHOW didn't hit any valves!). Replaced the chain, motor runs great and the interior of the car cleaned up like new. Exterior is now fully redone professionally (performed by licensed body men whom i'm friends with) so there's no worry it's a hack job that will chip and be junk a year from now. Had about 6 cars redone by them to date, all of which are local and look immaculate still. I have put almost 1k miles on the car daily driving it while I prepare for the swap gathering the necessary parts, as well as ran it down the dragstrip once to get a baseline for the car. In all honesty, i'm in love with the car, but it lacks heavily in the speed department for my tastes. My tow vehicle (2004 Silverado SS) bested it by over 1/2 second in the 1/4 mile and by 2 MPH trap speed, all while weighing almost 1800 lbs more. It's a stock natrually aspirated 6.0L GEN 3 chevy. I believe with the 6.2L GEN 4 LS3 under the hood of the Marauder, fed by 15 psi of forced Kansas air with some VP race fuel in the tank, the Marauder will be a whole different beast.....all while maintaining factory air conditioning, overdrive, full interior and creature comforts as my last one did.

Leakdown and air testing of all valves/cylinders on the affected bank right after I determined root cause:

The heart of this girl already has a new owner as soon as it's pulled, and is going in a Marauder with a truly destroyed engine, all while mine continues on under new 'Management' as i'll put it....haha.

Getting closer to go time!

This conversion reminds me of the old "Fordillac" conversions from back in the day. I met an old-timer who built his back in the '50s and was still driving it decades later...very cool car IMO even if some purists believe that he "bastardized" a nice classic.
 
I feel like I need to ask because I just don't understand, why do so much people get butt hurt over what engine goes into what, it's just a car get over it. If you care so much just go look under your hood and forget about this thread

Maybe because it's a MercuryMarauder.net site?

Who cares who wins the Super Bowl, it's just a game.

If it drove by you still say damn that was a nice marauder!

And I personally don't care who wins the Super Bowl, as long as I hit on a square :P

Where is the like button on zero F's given on motor brand.

If it makes you guys happy maybe he'll do the covers in ford blue :lol:

Again, OP owns a MERCURY MARAUDER............... if he shut his hood and didn't say anything to anybody some of you idiots wouldn't know the difference anyway............

Getting closer to getting her on the operating table!

I've got another conundrum.........

5.0L Modulars are getting VERY lucrative right now on price......

I'm currently putting the numbers together for a Coyote turbo setup, but time will tell.....

If I offload this LS3 i'll have a bit of coin to work with combined with the coin from the stock 4.6L 4v.

BUT.......this presents a lot of challenges as well for me.

Biggest immediate issues I see are:

1. ECU system. I'm obviously going to have to invest in some Ford tuning equipment/hardware.

2. Use the 4R70W or just go all out and work with the 6L80E? Most obvious would be using the 6L80 as if I go 4r70W it would need a separate controller I would assume.

How much can a 5.0L (F150) Coyote handle HP wise on boost? I've heard they are tough, but HOW tough?

any help and feedback/opinions are appreciated!
 
In this instance, i'd run the coyote ECU and integrate it into the Marauder, which basically requires little to no work as the Marauder is an older 'dummy' system as I refer to it.

My tuning software (HP Tuners) does Ford ECU's as well, as i've tuned some Coyote pickups already. However, none forced induction and last I knew they were still working on a vehicle security (PATS) workaround in the tune, however it was coming very shortly. This way, you could use the stock ECU's to run them like we do with the Chevy's.
 
Just to clarify, this is the same approach as the Chevy swap; run the engine only with the Coyote ECU, and run the rest of the car with the OEM ECU? I would not be surprised if the Coyote expects to see more than the engine connected, PATS as you mention.

Good luck, the Coyote is an interesting subject not attempted yet AFAIK. Here on MM.net we love DOHC.
 
Correct lifespeed, however the factory Marauder ECU does nothing but run the engine/trans on these models. The gauges are still hardwired to the engine, ABS is standalone, as well as the VDM (Air Ride), ect. It's pretty simple really. As far as the Coyote needing to see more, with the HPT software you just disable the other items just like the Chevy ECU's we use, and it will simply run just the engine and transmission.

I'll put some leg work into research on this for the moment, SIMPLY because the Coyote i've found is for a very good price. I'll also be using the 6L80 trans removed from the same donor F150, so it will be a 5.0L/6 speed auto combo.

here's the MAKE or BREAK factor,

How. Much. Can. The. Stock. Coyote. Take. For. HP??


If it can't compete with the GEN 3/4 LS Stock v. Stock on boost without failing, it's a non-option.
 
Here is a Coyote blurb, the F150 lower compression ratio would be preferred for boost. They key weak-link component appears to be the connecting rods, followed by the pistons. The LS motor probably has powdered metal rods also, seems everything does these days. Just a question of who built in more design margin.

I'm sure MM.net is not the best place for Coyote questions, but of course we're interested to hear what you find out.

• A higher compression version of the 5.0L is found in the Ford Mustang, boosting power ratings as high as 412 hp and 390 lb-ft of torque.
• Piston cooling jets provide additional heat protection and piston longevity.
• 5.0L V8 features a forged steel crankshaft and cross bolted mains for strength.
• Oil cooler and deep sump oil pan give the 5.0L 10,000 mile oil change intervals.
• The intake ports of the 5.0L outflow Ford GT heads.
• Powder metal connecting rods, forged crankshaft, hypereutectic pistons.
• Ford engineers put a significant amount of effort into NVH (noise, vibration, harshness) control when designing the new 5.0L.
