03 GT converting to 5.0

CENTENNIALSTANG · Aug 21, 2006

Ok guys i blew my GT motor up lol. I wana do a 5.0 motor maybe a 331 or sumthing bad ass im also gona put a single turbo on her and C4 tranny. How much will just converting my car over for the 5.0 cost. Money isnt a biggy just time. thanx :SNSign:

IM sorry mod motors

Cheap route would be to set it up using a carb, and forget about fuel injection. You can run a turbo with the correct carb setup (beleive its called blow through???) and that would be bad ass. No one would expect that, lol.

If you want fuel injection then the biggest PITA is gonna be wiring it up. Keep in mind itll fit just fine, think of the Saleen S-351's in our body style... oh my GOD!!!

MM k-member, control arms, coilovers for a start... prolly need a crossmember for the C4... thats all i can help with being the suspension side... i know nothing of 5.0 motors so someone else will need to help.

If money is not an issue, but time is... I would say your best bet is to stay modular, do an aluminum block 302BB or 324 BB/stroker setup and turbo that. That seems to be your best bet for a direct swap.

Swapping back to a 5.0 pushrod may or may not turn out to be a lot of work. For one, you need new motor mounts, all the stuff Torinalth said, your accessory hookups will all be different, you'll need a new midpipe, and it definitely will not be emissions legal if its carbed. Plus I think since the engine is older than the car itself, it wouldn't pass a visual inspection but I'm not sure (don't know how inspections work where you live). Then you have to factor in block strength... you'll need a Dart block (or similar) to prevent splitting once you start upping the boost. Just seems like a big PITA to me

4.6L Mod > 5.0

But seriously you would be alot better off just rebuilding your current motor. It will take 1/10 of the time to comlete and probably will not be much more expensive.

my95gtstang · Aug 22, 2006

i was thinking about converting to a 5.0 but the cost isnt worth it. just get a remanufactored motor from jasper, Titan Engines *ebay stores* PROMAR Precision engines *ebay store* or Egines Direct *ebay store* and they are for a damn good price.

Mike97gt · Aug 22, 2006

Please it's 2006 do not run a carb

Fuel injection offers the same amount if not more power potential without the driveability inefficiencies that always plagued carbed cars.

would you feel comfortable wiring a EEC IV car from scratch? I think your best bet would be to find a 94-95 5.0 car and take the entire harness out of it and take lots of pictures so you can see where all the grounds are and such..

BTW I don't blame you for wanting to go with a 5.0 based motor. the 3.55 bore on the 4.6 = crap..

plus depending on where you are in the country, that swap is not legal.

Can u run carb set up in our car and still pass emission?

bdcardinal · Aug 22, 2006

no. carbs were phased out before OBD2, and actually will not work with a factory OBD2. if you tuned it right you MIGHT pass tailpipe, but no way you would pass visual or a computer scan check.

I live in NM no one cares at all what you do to your car. But i was thinking about it most of the day and i think im gona stay modular but do the stroker kit to it. Much easier and if im mistaken correct me, but if i blow lots of money on a stroker then boost it.Then spend lots on the 5.0 motor it wont have that much of a power difference.

Don't go stroker.. go big bore.. the mod motors biggest problem is lack of bore.. put it this way STOCk our bore/stroke ratio is worse than a 302 based 347.. If you don't beleive me ask around the internet.. almost all the top modular guys will tell you big bore is the way to go.. I don't mean asking engine shops.. go to the boars and find the most knowledgeable guys that are not trying to sell you somthing and see what they have to say.

One of the biggest problems with the samll bore design is that it limits us to small valves. even with stock size valves you will show better gains from a BB than a stroker. take a look at the valve size of 302 heads out there compared to the modular heads. this is because the bore size on a 302 is 4.00 compared to our 3.55

If money REALLY isn't a problem. You can't go wrong with Sean Hyland's 5.0 Cammer. Leaves room for boring too.

I know someone on here hates Sean Hyland, I think its TomMustang

CobraRed_96_GT · Aug 22, 2006

Money no prob? get the new 5.4 ford has But seriously just buy a 4v dohc and maybe bore it and change the compression to like 8.4 or sumthing b4 u turbo it. Saves u a whole bunch of time and frustration with electronix

Yeah tom likes sean hyland about as much as he likes new jersey. BTW where is tom?

Torinalth · Aug 22, 2006

he poped up once in the Ot forum in general reciently... aside from that i dunno.... getting annoyed that i cant even get suspension theory bounced off anyone since both he and San dont like my threads

SHM is awesome if you dump a LOAD of cash on them at once.... if you nickle and dime then yeah, yer not going to be happy. remember, its the huge jobs that MIGHT get into a Magazine or gain renown at the track.

Stroking a 4.6 to a 5.0 is not a bad choice. I am doing it but i have yet to begin on it. I have been researching, its not as common but it is do-able and doesnt cost that much. The kit itself is only around 900-1100 off ebay stores which is really nice. Trust me, research into stroking the 4.6 to a 5.0 and you will be impressed. The only thing is that not many people have done it so finding out exact dyno numbers and stuff like that is going to be difficult. Once i begin mine i am going to take pics the entire way and then list all the parts and all the info so that if someone else wants to do it, they have something to go off of. let me know what you decide to do. later man and good luck.

I have heard many, many people say that the mod motor needs bore not stroke. Matter of fact SVTTech who is a highly experienced Ford tech said it in this very thread See post #13 in this thread ^
