^^^LOL trust me my friend. I know. I just finished spending over 6k just on the supercharger for my Porsche and that is without a lick of labor yet. just for the kit.
I am really serious about dropping a V8 or SRT motor into my Xfire though so I really appreciate what you guys are doing.
I've always loved cars and in my almost 22 years of driving I have owned several performance cars. Not one has stayed stock yet.

I am hoping to have the engine in my garage by nest weekend! Just as an FYI, I would love to see a new Hemi in one of these. The Hemi has a reasonably priced aftermarket for lots of added HP if needed. What some people may not know is that the Hemi uses a Mercedes transmission like ours but with a different bellhousing pattern. If you had a Hemi with the trans you could probably make the conversion work. I went Mercedes as this is initially less expensive and an easier bolt in. I also wanted to keep the car all Mercedes in spite of the Chrysler badges. I also think the Mercedes is better from a weight and balance standpoint. The Mercedes engine is all Aluminum while the Hemi uses a cast iron block. With the Mercedes I am only adding about 130 pounds to the front which is about the same difference between an SRT and N/A engine.

Re: V8 Crossfire Conversion Diary
Well I am about a week behind schedule, but I did finally get the new engine loaded on a truck and it is now headed for Dallas! By this time next week I should be cleaning and detailing the engine. The engine is from a seller in Sacramento who bought a complete but wrecked 2002 CL500. The car was totaled after only 11-12 months on the road per Carfax. So I am estimating the mileage at or under 15,000.
I want to thank our forum member Ravenous who was willing to check things out and make sure I wasn't getting cheated.
Here are some pictures of the engine. If you look close you will see that it looks just like our V6's but with two more cylinders.

HDDP, you you see the resemblence of the V8 to the V6?
Here is a picture of a C43 engine. Note the exhaust manifold. The look like they might bolt right up to the stock down pipes. I have located the manifolds but didn't want to buy them until I knew I had an engine. I will be buying the manifolds and electric fan soon now.

Speaking of the tranny, have you verified that the bell housing is the same size, design and bolt patterns ? Even if it is... Since the engine is much longer than the V6 how are you going to get the engine to align longitudinally when you have no room to move the engine forward...
Just my humble opinion, and I might be wrong, but I think you're going to have to do a serious rebuild on the front end of the car to get that thing in there... First thing I would do before you even un-pack that engine is start making some comparison measurements... If you need me to give you the measurements of the V6 bell housing and distance of the motor mounts, I can do that fairly easily since my SRT engine is sitting on the engine stand...

I would guess that you'll have to "shoe-horn" that engine into the bay, relocate the engine mounts on the frame and shim the engine to align it with your tranny... I'm concerned that you'll not have enough lenth in that engine bay... You may have to cut the firewall to make clearance for the throttle body...

The automatic trans is the same one they also put behind V8's. I have verified that the bellhousing has the same basic bolt pattern but have not verified 100% that it is the exact same size. The Mercedes Tech that is helping me with the programming claims it will bolt right up. It will be nice if it does.
There won't be any cutting needed to the firewall. The rear of the engine will sit in the car exactly as the V6 does with everything including the throttle body in the same position. I have looked at a couple of Mercedes cars with both the 320 and 500 engines and they chissis's are the same as far as motor mounts go, so I am hopeful I can use OEM parts to bolt it in. If not, not a big deal, this is the type of work I am very used to. When my engine get here next week I may ask you for a couple of bellhousing measurements if you don't mind. I was planning on putting my car up on stands and taking more measurements as soon as I have the new engine to compare to.

Here is high resolution/large photo of the Startech V8 Crossfire. You can see the thinner electric fan. Everything else under the hood that is visible is in the stock location. Once the picture opens, click on it and it will get even larger.

Re: V8 Crossfire Conversion Diary
I got the call from the shipping company that the engine had arrived! I picked up the engine and just finished putting it on the engine stand. I will be cleaning and inspectiing it and fixing anything that needs attention. One thing that I did notice is that two of the very small wires that are part of the harness that connects to the computer are frayed as if a rodent was munching on them. Anyone know if there is any harm in splicing in some new wire to replace these two bad spots?
