Possible 2003 motor Swap
#11
I'll have to look into them. I am only planning on going up to around 400-450 hp anytime soon, but I plan to have the engine built to be indestructible and would like the transmission to be able to handle upside of 800lbs of torque, if I ever decide to take the engine further.

Does anyone know where I could pick up a "rebuild to stock" kit for a 4.6L f150 engine? And is there another vendor that you guys have had good experiences with for racing rebuild parts? The only place I have any experience with is summit. Anything else good out there?

I have an 03 v6 5-speed manual. I have become terribly bored with this car. I am looking to do a motor swap with it, and I am thinking of swapping either the GT motor for that year, or buying one of the coyote 5.0's. I have been told that this is an ridiculous swap to do, and that everything has to change. Beyond the obvious (engine, transmission, drive shaft, differential, motor mounts, (I imagine computer stuff)) what else would I need to do one of these swaps? Is the difference in the weight of the engine enough that I would need to change the suspension as well? Bigger fuel pump? Major electrical work? Any insight from anyone who has done one of these before? I made an inquiry on here before about it and the general idea that I got back was "Go buy a gt" but that isn't an option because my insurance would SKYROCKET. Anything else that would need to change for the GT motor to be in my car?
Engine
Engine harness
K-Member
Alternator
Computers
A/C
Cooling
Transmission/shifter
Drive shaft
Rear end
It's gonna run you right at $25k (no matter which of the three engines you choose to use) if you buy all new stuff. Fortunately the only thing that needs to be fabricated is the exhaust, and that's only if you go pushrod.
If you get a used engine, do it right and take advantage of the motor being out of the car - rebuild the motor with higher quality performance-oriented parts (forged bottom end, ported heads, bigger cams, etc). It would really suck to do all that work only to have the motor give up a couple of weeks later.

Just let me know if there's anything I can help with, I'm on here petty much every day.

Thanks. I have a web page with a cost break-down.
BTW, they opened that thread up again. Some folks are too full of themselves for their own good.
My build will have a forged bottom end and AFR heads.We're expecting between 500 and 550 HP and at least 500lbft of torque...

Dont forget suspension and fuel lines. But I'm looking at finding a wrecked or junk GT or F-150 for sale to pull most of the BS parts from. Pull the drive train and get it rebuilt. Then get the other misc parts from the car, ie: fuel lines, suspension, etc. Anything that's shot beyond reuse I'll obviously have to replace, but it'll get me access to all of the other accessories that I'll need.

Also, does aynone know how frequently a clutch should wear out? This is my first long term manual car, and I just changed the clutch a few months ago and I'm wondering how long it's going to be before it should start giving me trouble. Inb4 "depends how you drive it."
