Stock looking for significant hp/tq gains

[itsgreenmoney]

I want 550hp to the ground with daily driver drivability! Where start/finish

[RubberCtyRauder]

Big bank roll $$ $15-25k, cobra, mmr or similar block, forged internals, supercharger, bigger brakes, 31 spline axles, beefed up transmission..the list goes on

[itsgreenmoney]

Well all I really know at the moment is replacing the rods and pistons is a must for that kinda power. I want to supercharge but which ones fit? What does "cobra" mean?

[itsgreenmoney]

Oh sorry I got you on the block. Can the stock aluminum block not handle the power I'm looking for with internal upgrades?

[RubberCtyRauder]

There are no supercharger kits for Marauders anymore..It has to be pieced together with a combination of Marauder specific parts and mustang parts, generally a cobra mustang. Commonly called an eaton swap which there is a list of parts to do that in the forum under power adders. That is using a eaton m112 blower which wont get you 550 rwhp. more like 425 rwhp. you will need a 2.3 twin screw blower or you can go with a larger centrifugal blower from vortech, ADTR.net has options for marauders.

the entire driveline needs upgrades to handle 550 rwhp and fuel pumps and injectors and it is not inexpensive.

[RubberCtyRauder]

stock block should be good for 600

[itsgreenmoney]

Thank you sir! I'll do some looking around. I'm just getting started and very new to this. Actually this is my first car I've ever bought! I've added a K/N CAI and SCT tune with 4.10's motives. Is there a better tune for my stock setup that you know of?

[RubberCtyRauder]

yes, talk to Marty O, here in the vendors section MO's Speed shop. they have a better tune than sct for sure and work on maraduers weekly, MIne has been there twice and will go again next year for upgrades.

Thanks allot! Its nice to talk to someone who knows something about my car!

Without knowing your objectives, other than 550 HP to the ground, it's not realistic to say which modifications are needed and which are just nice to have.

I have a stock engine that dyno's @ 430 HP with 132K miles on the clock. I'm using a 10 PSI centrifical supercharger and kit. I couple it with two drive train mods, 410 gears and a 3500 stall speed converter. I have a lot of fun and run with the big dogs, (well, maybe the medium size dogs). The motor has held up very with just a valve job due to an overheating episode, not the cars' fault.

Increased horsepower also requires better stopping power and better suspension components as posted above.

Refine your objectives and we can steer you down the primrose path.

Regards,

[itsgreenmoney]

Well My car is a 2003 Marauder(black) with 45k miles. I doubt I drag the car just lil street light to light stuff. I want the power 500-550hp daily driver capable and great loppy sound. I plan on running fairly wide tires 285-305 in the rear with 20in rim. I want to improve handling but doesn't need to be track ready! I was thinking going Stainless Works full exhaust. I'm not really sure what you need to know. I'm a quality guy and like to know its done right!

[Pat]

I'm just getting started and very new to this. Actually this is my first car I've ever bought!.

I didn't see your post when I wrote mine. Doesn't change much but here's a bit of philosophy from member "blkZooM".

"if it's cheap and reliable it isn't fast.
If it's cheap and fast it isn't reliable.
If it's fast and reliable it isn't cheap."

Words to live by.

You know you live near MO's speed shop, our premier performance shop owner. He's located in Dallas, Georgia. Talk to him or his in-house experts and they can steer you right. It's less than 200 miles from your city to MO's.

Cheers.

[itsgreenmoney]

Ok thanks. I looking forward to investing some money into this project and getting done right, because I plan on keeping it. So whatever you an suggest is more than welcome! Have a good day sir.

[J-MAN]

You might consider buying one already built.

[justbob]

The info is all here on fitting pretty much any blower you want. There have been a couple dozen (probably more) Eaton swaps, Whipple 2.3's, 2.9's, 3.4's, a 4.0, a couple of turbo's, Voretec's, F1 ProCharger... The list goes on.

I drove mine bone stock from '04-'09 until I joined up here and met a few locals.. Not too sure how it happened, but I've repurchased mine in dollar amount at least once again LOL. Maybe the last seven years of no car payment helped? [emoji1303]

If its your first car do the simple and less expensive items first. Get a good tune and change the rear gears to 4:10s. I had a stock block with 476 RWHP and almost 90k of supercharged fun. The biggest bang for the buck for me was changing to larger breaks, mae a big difference around town with these barges. If you aren't going to the drag strip start out a bit slow and enjoy the car. once you start there is never enough HP just ask Bob ^

[Dragcity]

Nice goals. Not sure what you have driven before. 550 RWHP is on the edge of street max in my opinion. You can get into a lot of trouble fast with that power level.

Reason I say that is we have lost a few Marauders and, sadly, one member. Hate to see any more tragedy in our little community.

Marauders maintain very good manners when not in boost. I have a Trilogy supercharger (no longer available new) and it works great, but no where near 550 RWHP. Good advice abounds around here. I have heard great things about Mo's and cannot wait to get down there myself.

I have been kicking around building up a new engine to handle more HP, and my research has led me to look into the 302 Boss iron block.

Welcome to this fabulous site and people. Good luck. And by all means have fun.

[Pat]

Oh by the way, wet streets are not your friend. Marauders tend to swap ends rather easily, even stock, so be aware and careful.

[F1erceK]

ADTR.net offers a turnkey supercharger kit for these cars. If I don't get the Trilogy kit for sale here I will eventually get that. Base price for the kit is $6,400.00

[Spectragod]

Double that figure, if your paying for the work to be done, maybe X 3 or 4.

I can't speak for others, but I have a boatload in mine @ 521 to the wheels, and drag radials are a must have.

I agree, labor will add significantly and you prolly have more than 521 with the pulley swap you did and KC:burn:. You should anyway

The 302 Block is what I have and everything under the sun to go with it. Start with about $30,000 laying around and find a good tuner.

[Gryphonzus]

I have a 2003 with a stock block and a vortech supercharger. It is putting about 480hp to the ground. It has a stage two transmission in it. I have been driving it fairly often for the last three years and now the transmission is acting up. I have a long list of modifications also. As the others have said adding horsepower causes problems the more power the more problems. I am pleased that my car has not had that many problems all these years. I am planning on building another engine and transmission to replace what is in now. Unfortunately it is going to take awhile to slowly gather the money and parts. Good luck with plans.

[Catfish]

+1 on Mo's Speed Shop. Very knowledgeable on our cars and great customer service.

[itsgreenmoney]

Honestly I love you all for your inputs and support. I may lower my expectations on the power a lil. Like I said I'm not gonna drag it I just want to go FAST! I'm gonna give the forum a good look around and also go to Mo's. Thanks allot fellas. I love diving my car!

believe me, 4.10 gear and 425 or so rwhp and you'll break traction and be very happy for alot less investment. Marty will steer you right with hp goals and budget

[Turbov6Bryan]

Put a Chevy LS with 4l80 and get a turbo
5000.00 and make 700hp
10000.00 and make 900hp all the time

It's still a marauder;)

[blkZooM]

First thing first, never use "invest" and car mods in the same sentence, realistically you are wasting money. Understand that this car sucks from factory compared to a lot of the newer sedans that seem to handle all the power people dare throw at them, this is not one of those cars. Getting to 550 isn't so hard I think, it's keeping this car together at that power level that is the challenging part. A lot of the parts on the drive train must be upgrade and that is where it get's pricey fast. I think for 15ishG's you could have the power you want and a real reliable car. Built motor, built trans and supercharger's will be where all your money will go to.

In all honesty I've tossed around the idea of throwing in the towel on the Marauder and going with a Pontiac G8 LSA swapping (basically Eaton swapping for the Ls3 guys) it and just enjoy the making more are more power. People make over 700 rwhp with those cars and they are stock besides the blower and fuel system. But my Marauder is paid off and I am in LOVE with how it looks and don't mind spending the money and trying new things to make it faster.

truth be told this would be the best of both worlds to "me" Lsa swap 6.0 or 6.2L with a 4l80e in a Marauder. That would be bad ass

[sailsmen]

Big difference in cost between 450RWHP and 550RWHP.

[cat in the hat]

This.

If this is your first car, "550 rwhp" is probably just an arbitrary number anyway. What you're really saying is "I want a big, strong, fast car."

My Trilogy car makes a little under 400, and if you could drive it you'd smile and say "That's what I want." In your application, you'd never know the difference between 400 and 550 and you'd be just as happy.

Maybe happier - you'd have about $10k that was still in the bank, and you wouldn't be breaking **** all the time ;)

[guspech750]

I choose the Eaton swap route with 4.10 gear, stock exhaust, Wilwood brakes and some suspension mods. It only made 400rwp and 410rwtq or somewhere there abouts on the stock motor. But it's still silly fun.

In over 5 years. It's been OEM reliable and I like the OEM look of the swap. Which has cost me next to nothing to maintain. Of course I'd like more power. But I have other hobbies I spend on. Good luck on your quest.

I want 550hp to the ground with daily driver drivability! Where start/finish

This is kind of what I wanted so I bought a car ready to go but with 450 rwhp. I've got about 14 grand tied up in it and almost zero time except making a few things perfect. I wasn't looking for another Marauder but this one found me and it was too good to pass up.

I think anyone would be pretty happy with 450 rwhp in one of these as a daily. If you were closer I'd let you take it for a spin, it's reliable and very fun.

I usually build my cars but as I mentioned for 14k I have a super clean, reliable fun, fairly low mileage Marauder, it just turned over 50k. 14 grand that's not a lot of money for what it is. I couldnt find a clean Marauder and do to it what's been done for even double what I paid for this car.

With what I have the MM has had no issue with newer 5.0's, camaro's or challengers, even with its weight 450 hp is enough but my wife still won't barely drive it. I personally went 12.6 with it at 110 mph and a *****y 2.2 60 foot two weeks ago. My 550 + hp car went 10.87 at 124 track was **** and couldn't hook that same night. I think the MM gives me more smiles per gallon as people don't expect it from a car that big. I did one run with the MM and I'm sure it could have gone a little faster with a better e.t.

I will bet is has a lot more, street manners are a thing of the past, and the car has a different "feel" on 1-2, 2-3 shifts @WOT, a lot of rear tire sidewall flex going on...... When it hooks...

[itsgreenmoney]

I guess I can understand that these cars aren't as technologically advanced and the current modern cars so maybe my 550hp number is slightly inflated considering i want good reliability. Thanks allot for your inputs!

[sailsmen]

What you will spend to get to 450RWHP to then get to 550RWHP on a daily driver/racer can be what you spent to get to the 450RWHP.

And yes the HP Wars are at an all time high.
