5.4 4v 2000

[mrmustangconvert]

i have decided that i am going to build a 5.4 4v motor for my 2000. my primary goal with this project is to buld a 1000+ hp turbo car. from the start i am just going to drop in a mostly stock navigator motor with a sullivan intake and cams. basically i am building a cobra r, but without the cobra trim. its pretty much going to be a track car, alot like 96gts car. so i thought i would be different and build a 5.4 4v instead of the 2v. so any info about the transmission (clutch) and wiring harness would be helpful. here are some pics of my gt :jester:

the mustangs apperance has changed, right now i took off the wing and added 03 cobra rocker panels and hood.

:metal: sweet ride. twins or a single turbo. i would go ahead and look into a trans.

if your goal is just 1000hp you really don't need a super radical build with a turbo 5.4 4v...alot of people make that with the dohc 4.6 with a turbo...al papito ran 9.98 with an NA 5.4 4v

I kinda agree for simplicity sake. I always wanted to do a 5.4 4v though.

It would be alot less of a hassle to make that kind of power with a 4.6 4v. You could still go 11s with a bolt on 4.6 4v before you go turbo.

a 5.4 4v is really easy with a navi long block and a sullivan intake. that was what i was thinking of doing after my first 5.4 blew. but i want a 850rwhp 2v 5.4 first.

i plan on putting a massive single turbo, but i dont know what mm its going to be. i guess you can say the 5.4 is the equivilent of the old push rod 5.8, and you can get 17 percent more hp over the 4.6. what i want to do from the start is make it a a fast NA car then turbo it in the future. i always loved the 4v motors and having more cubic inches sounds pretty sweet. i am also keeping the manual so i can have a little fun in it.:snatch:

with a large frame turbo on a 5.4 4v your are looking at alot more than just 1000hp

i will say building it fast na and then doing turbo isn't the best idea, NA= high compression, turbo needs much lower compression...you would have to change pistons when you went turbo

thats a good point, but with stock internals (assumming that i already have cams, intake for it) the compression ratio is 9.5:1. since it has good factory compression with the addition of the cams/intake im just going to play with it as is. with this combo im hoping to have somewhere around 400 hp to the wheels. now when i get ready for the turbo i am definatly getting low compression forged internals, compression im thinking of is around 8.5:1.
