4.8 in serious need of mods

[kinjo1977]

Just looking to get a good list of mods I could do to my truck to get it going fast. Got the 4.8 and don't know the first thing about engine mods really.

Things I know of doing:

Adding Ceramic coated headers
Nelson Tuning
Adding an Intake
Adding a Shift Kit
Adding a Stall Converter
Adding a cam...not sure what to go with cuz I honestly couldn't tell you what a cam is
Duallling the exhaust
Granetelli Mass Air Flow Sensor
Throttle body spacer <which to me don&#39;t do a damn thing>
Supercharging
Adding a shot of NOS
and....that&#39;s all i got

BUT I NEED CHEAPER MODs ...all those things run 400+
Oh well...guess can&#39;t be to big of a cheap ass

You got to pay to play man...I know. It sucks
All those things you listed except the Granatelli MAF sensor and the TB spacer and you should be one fast 4.8

dont mess with the mas air flow, seems ours flows just as good.
waste of money in my opinion.
also dont waste your money on the spacer thats a hundred bucks that could go to something else, unless you just got to have one if so, i have one right here i&#39;ll sell for 50 + shipping.
other than that you are heades in the right direction
you might want to add springs and pushrods to that list if your going to do a cam swap.
and yes it&#39;s not cheap to mod by no means, but as chingon stated you have to pay to play.
hell ive got mmore than 8 - 9 grand invested in mine. not all in the motor but just everything that i have changed on it so far. helll spending that much i could have alrady bought me a radix

[kinjo1977]

So would you say the best thing to go for first would be a Radix? Cuz if so, I need to start saving my money Anything in particular I would need to add to my engine in preparation for the Radix?

you can do a hot water bypass and remove your mass airflow screen. radix or procharger whould be your best bet. I have procharger on mine and i love it. But ive heard really good things about the radix to.

[kinjo1977]

Oh yeah, don&#39;t hesitate to give me any power ideas you have. I don&#39;t have to go through any inspections here. I live in the countryside.
How would I go about descreening and doing that hot water bypass? Are those fairly simple mods?

[kinjo1977]

QUOTE: This all-new intercooled supercharger system utilizes the Magna Charger MP112 supercharger with internal bypass valve. Torque and horsepower increases are improved 63%-125% from 2,700 rpm to 5,500 rpm, giving more "power under the curve" than any other supercharger system available. This translates to 130+HP to your rear wheels&#33;
........................hey i got this from Project R&#39;s page.........you think this would be good for my truck? I really don&#39;t want a s/c that will be too loud.

[Chingon]

I&#39;ve driven a Radix powered truck, and heard the same truck drive by at WOT. It isn&#39;t a sleeper blower at all. You can hear that thing roar&#33;

[blown02]

there all loud whipples and radixs arnt as loud as a procharger at idel but when your on it there louder. theres 2 hose lines that run hot water through the throttle body on the bottom side. you remove the 2 lines and connect them with a barb fitting. Just take like a screw driver and get crazy on the screen to get it out.

Since you said you&#39;ll have to start saving for your radix anyhow, why dont you take another route. A radix with install will probably end up costing you around &#036;6,000 and probably put you a lil bit over 400hp at the flywheel (In Truckin&#39; mag). Instead, maybe do something like Smoke_Ur_5.0 did over at LS1Tech. He&#39;s putting down near the same numbers with only a Cam/Tune/Pulley/Cut-out/Air Intake
A radix is also gonna add alot of weight upfront which our trucks don&#39;t need.
Cam-400
Springs-100-200
Tune-400
Pulley-200
Cut-out-40
Intake-250
Around &#036;1500 plus labor, unless you do the mods yourself. just a tad bit cheaper? A power adder would be a great mod dont get me wrong, but i just wanted to throw somethin else out there, so you dont think theres only one way to go.
