Hi im new here, but not exactly new to modding...i have an 03 GT 5-Speed with a bunch of bolt ons, i wanted a supercharger but i decided to get heads first. So heres my question what else needs to be upgraded when i change my head? I got a gasket kit from Ford Racing, 30lb Steeda Injectors and Stage 3 Crower Cams...oops the heads are Patriot Performance Stage III's which come with PPvalve springs and aftermarket valves aswell (i forget who makes the valves but...) What else will i need to do tho? Different plugs? Stock Fuel rails ok? Timing? Any help would be greatly appreciated, thank you

youll need to have those heads looked over by an experienced shop. there is only one shop out there that sets up the springs right and thats shm! those heads and cams will make power but will be very hard to tune down low and will soung great at idle but will not be real driveable at low rpms. stage 3 usually only make about 15-20 hp ver the stage 2! stock plugs should be okay on that setup, fuel rails will also be okay! id like ot hear your car after you get em on. gonna sound badass!!

If your gonna be revving high I'd really suggest going with forged rods (and might as well pistons). I assume you'll want to rev to at least 7k rpm to take advantage of those heads and cams and I wouldn't be comfortable doing that on the stock stuff.

[drgnracin72]

i wouldnt either. i revved mine to about 6800 and if you look in the thread about my blown motor, you can see what that does to a stock engine!

man i say go for broke, i revved my car to 8k with the blower on with a stock block, and it made 18 pounds of boost lol. WHT00Gt can attest to that

it was only when i was mad at the wife, i just kept it to the floor and shifted when it wouldn't go any higher, it didn't have a rev limiter. i know i am stupid

Thank you for the help you guys, i didnt know that about the powerband. So where is a good place to shop for forged rods and pistons? The website i have shopped for the last 6 months doesnt go below top half of the motor. If i were to send the stage 3 cams i have back and get stage 2's instead would this eliminate the need for forged rods? Thanks again, and im glad i found this site.

youll be fine right now with those heads and cams on the stock motor, but if you decided to put a s/c on it or some nitrous, your gonna need to do something with the bottom end. i think youll make somwhere around 325 hp with those mods. but then again if you really want to take advantage of the heads and cams its not gonna hurt! i would suggest dss racing, vt engine, or coast high performance. they all have very good and experienced shops and could hook you up with anything you need!

[stangliter04]

you know if you are going to take the heads off anyway do the cams they are going to have the motor opened up anyway... cheaper labor

where are you located?

[MySallyMI]

Im from Grand Rapids, MI originally, but am an active duty Army Mechanic stationed in Ft. Hood, TX when i am stateside. I have 3 months to go in Baghdad, IQ. I dont have all the parts installed yet, just formulating a plan for when i get back. I have a bunch of bolt ons in boxes waiting for me when i get home, driving my wife and mother crazy. But you made a good point Stangliter04 about havin the heads off and doing the pistons and rods all at the same time, think thats which direction i will go, thanks again all

[drgnracin72]

yeah wont hurt to do it all at the same time, but that means more money and down time!!!
