Hey guys,

I have been slowly mulling over the idea of posting on here about the rebuild I'm about to partake in. I have a 04' Crossfire, 6 speed; I've done a few things already since I've bought it back in 12'. I've replaced the head gaskets, intake valve gaskets, belts, EGR sensor, whole clutch assembly, all four tires and other less important things such as hood lift arms, weather stripping, redone the headlight lenses and now I'm looking to do more.

I want to make this project more of a community build for everyone here. Take ideas from those who have experience and voice my ideas on where I want to go in modification of this car. Few long term and short term goals is flat black paint, few flat burnt orange accents, new powder coated wheels with the same paint scheme, lambo doors, new interior to match exterior, bucket seats w/3 point harness. New interior plastics (if anyone knows of where I can get this, please advise), and eventually rebuild engine with zero miles and add a stage one turbo, cold air intake and a few other mods as well as something like a diablo sport racing chip.

Obviously I could go down the rabbit hole here with this which isn't what I'm looking to do. I want to get it done right and right the first time and I want to share it with those of you on here who share in the passion of this car and I really would like to share the journey with you guys.

I'll post pictures here soon enough so we can visually track the progress. All your guys ideas, input, and advice is always welcome. If you know where I can do something or get something at a better price or a quality, please let me know!

 

That is your 1st major problem, not much point rebuilding engine where there are no modifications to do to it, unless you bore through the alusil cylinder coating and bored it for ford 4.6 3 valve pistons, as of now there is NO tuning available for the mercedes computer to add any kind of boost for a original NA crossfire the 280,000 lines of coding is part of the problem.
Most ppl look at just adding a mercedes v8 which can be done. But they are used engines and rebuilding the mb v8 is the same boat as the v6. If you want to have a modified engine you are into ALOT more work changing whole driveline gauge cluster ignition etc.
The pentstar v6 engines have been alot of improvements including 4 valve heads and soon a direct injected twin turbo v6 making around 700 hp

 

Thanks for the reply,

That's exactly what I need insight into the Euro and Mercedes engines as I've always dealt with American.

The engine I have runs great and I treat it amazingly, oil, plugs, plug wires, gaskets, the works. The only thing I don't like is the high miles on it, not sure why other than I'd like the have a engine thats broke in right over a few thousand and work from there.

I'll look into those mentioned and see whats best right now I'll continue modding the one I have and worst comes to worst, I'll sell that engine. Right now, I'm having a problem with something draining my battery if I let the car set for more than a day or two with out running. Any ideas?

 

Remove the negative battery cable and connect an amp meter between it and the terminal. ( cheap multimeter in amperage mode )
Note the amperage draw with everything off ( doors shut etc ).
Should be around 20-30 milliamps.
Start plucking fuses one at a time until you see the draw drop, study the service manual schematics for that fuse and isolate the source.

 

Thanks for the heads up and pointing me in the right direction. I have a Harbor Freight right down the road, so I'll go pick up an amp meter there here in a bit. And we'll go from there. Thanks for pointing me in the right direction! I may have more question as electrics isn't my strong suit.

 

There are no aftermarket chips like the Diablo Sport for our MB engines, mostly because the computers are more complicated. Also, if you add a turbo, you risk engine damage, the SRT6 SC'd engines have a different crank and connecting rods, etc. to handle the added power.

 

Srt and NA are supposed to have same crank and rods just different pistons for the drop in compression to 9.0 for the boost

 

So, other than boring for bigger pistons, there really aren't much in the way of mods you can do to these engines. Not even chip wise. I've read else where than turbos are bad for these particular vehicles, but I don't understand why, bc its aluminum?

 

If you want more power, forget about chips and turbos and buy an SRT6.
Whatever you do you will get left behind by the stock SRT, plain and simple.

 

You can check but I believe that the cranks and rods are heavier duty, could be wrong, I was once before. LOL

 

CS, Rods and pistons have different part numbers in the parts list.

 

The srt has amg stamped on rods, but both are the same forged rods just one set has amg stamp

 

OK, you believe what you want. It's not a priority of mine to convince you, I was just giving my opinion.

 

With proper maintenance, the stock engine should be good for 200-300k miles.

 

One things I've noticed lately is a I have a parasitic battery drain and I'm trying to resolve the issue, I've checked the alternator and battery (which I replaced about a year or two ago). I've been though all the fuses and checked/replaced a few that weren't so so good of condition. Has anyone else had this problem or know of a singularity issue with Crossfires and battery issues I might be unaware of?

Thanks!

 

I keep up with maintenance and service on the vehicle religiously. I even have a car folder that I keep that has every receipt of everything that I've done to it thus far. If you've ever worked in the government, then you know what I'm talking about. lol

 

Not trying to start a argument, just what i have had others tell me.
If u know facts other than part numbers please say.

 

Update:

Hey guys, so I had ordered a few parts as stated before, throttle position sensor and the EGR sensor and a new hood raise lift arm (which I just installed) lol quite excited about that. So, I'm about to do both sensors here in a few but now yet again, it's it amazing when you fix one thing another thing goes? lol I did the valve gaskets and then I needed intake valve gaskets, replaced those and now I noticed a leak further down that is dripping onto the catalytic converter so now I have to fix that. lol

 

So, did some more work today. I found a tacker on my car prob from the original dealer (took that **** off). Done some more touch ups on to the engine and under carriage. I took the skid plate (plastic) off and pressure washed the whole engine. (yes it still works) got rid of all the road crap under and on it. Just going over the engine now, spot checking a few things here and there and seeing what all I need to grab from the ol' junk yard for replacement parts.

On that note, there have been a few splices into the wiring here and there, does anyone know where or what that engine wiring harness is officially called, I tried google, but apparently I'm not calling it the right thing. lol

 

When you say stamped do you mean done with a hammer and stamp or molded in with the forging?
Two part numbers most probably means to different parts.
They may look the same but different processes after the forging can result in parts with different characteristics.
