looking to see if anyone has ever done a 360 swap in a crossfire. not interested in Mercedes motors. I want an all Chrysler vehicle.

 

If you want an all Chrysler vehicle you need to look elsewhere, the Crossfire is all MB, built in Germany at the Karmann factory. Most MB SLK32 parts will swap right into the Crossfire. If you want to try a motor swap, how about a 340 SixPac? Shorter stroke, higher revving and plenty of HP.

 

Sounds like you need to pull the body and bolt it down to a Neon Chassis..

 

Actually, with just a few mods currently available for a NA V6, (CAI, Tune, injectors, K&N filters) you can practically duplicate a stock 340-6 pac H.P.
The biggest thing holding back the NA XF is the 3.27 gear.

 

Yeah! What he said.

I did every one of those mods to my NA, and am pushing over 290 HP

280 HP is quite do able on the NA Crossie. Needswings CAI, performance tune from Eurocharged. Throttlebody upgrade. Minor exhaust mods.

If you want to drag, follow firemax+'s advice get rid of the tall gears.

If you insist on an engine swap, go the 55 V/8 conversion.

 

Valk had his tuned and put it on a dyno and this is what he got.
Something is not right here. He has the tune, he has the CAI, he has the larger throttle body I'm sure. He is missing maybe 3-4 HP from the super duper exhaust. What is missing?
I think maybe you mean 187 HP at the wheels is possible. Senior moment? We all get them, even me. LOL

 

The answer is NO.... There has been 1 Hemi swap, but no 360. Who would want a Chrysler? I think Hemi, I think Dodge...but Chrysler....man... If I decide to butcher one to make it American. It will be a Chevy small block, 400 turbo, and 12 bolt Chevy .411 rear end....but, no Chrysler....

 

Why must you always,??????,,,,,nevermind.

I forgot, you have trouble with math.

Talk Crank or talk Wheel. Just don't mix them.

Since we lose close to a thrid of our crank to the wheels, 187 comes to 280 HP. My last dyno with Jake was 197 at the wheel. At least 290HP at the crank.

As for the super duper exhuast, a back Cat delete (in conjuction with intake upgrades) gains two to three HP according to the guys at Eurocharged. Take your argument up with them.

 

Let it go Franc.. it's that damn metric system conversion confusion ..

 

These figures of yours are not possible. Newbies will get the wrong idea.

280/290 hp is not in the books with those mods, I had them except for the exhaust.

Some people here do not like to upset you so they ignore your errors. I'm not trying to upset you, I just think those numbers are BS.

Not one tuner has mentioned 290hp, the best was 265 and that was laughed at.

Valk had 170 hp before the tune and gained 17 hp.
If losses were 1/3 then he actually gained 25 hp.
25 plus 220 = 245 hp, not 280.
But losses are not 1/3, they are approximately from 20 (manual) to 25% (auto). These may be a bit high but ....
Valks is an auto, (170/3) x 4 = 227 hp. A bit high,
After the mods, (187/3) x 4 = 249 hp. So a bit high as well.

This is a long way from 280/290 hp.

 

Whatever Dave,


Shall we get back to the OP and his desire to make his Crossie ALL Chrysler?

PV2Haish, You will have to change everything but the paperwork documentaion of the original sale to convert the Crossfire to a pure Chysler product. The only thing Chrysler in the car was the sales contract. And it was likely printed on paper made in China.


I believe a V/8 conversion with Mercedes parts is around $25K. Plus the donor car. It's your money.


Your best route, if you want more power from a Mopar drive train is Oledoc's advice. But,the Hemi required significant modifications to the front suspension and raised the car about 2.0" if I remember correctly.
After the build, he wanted $36K for the car.

Your 360 swapmight go easier but you still have to mateit tothe driveline andget it all to fit. I'm stating the obvious but when you are done you will still have a Mercedes product witha Chrysler drive. Not pure Chrysler at all. If it's just more speed and power, there are easier windmills to challenge.
Despite 180's arguments, you can get a lot more out of the 3.2 with available mods,,,or go SRT. Cheaper and much much faster stock than anything you can do to the NA.

 

The Hemi needed the charger front end too I thought? Firewall forward.

OP, if you are mechanically inclined you can do a V8 Benz swap relatively inexpensive. Depends on how overboard you want to go, but if I did a 55K swap my budget would be around $8K. Of course I do my own programming.

 

I believe you are correct here.. I do know the front wheels were kicked out further than "standard" setup..

 

Yeah I just remember seeing the bay and I was just in awe at how much work someone put into making that poor excuse of an engine (IMHO) fit in there lol.

 

but it was such nice work... looked and sounded awesome!

 

I definitely agree with you there! I'm just not much of a fan of Hemi's since I found out they were made in Mexico and after looking into reliability on the 06 R/T Charger for the family.

 

Now i'm a Mopar guy to the core but, I think you would be pretty disappointed in this setup in a Crossfire. The sheer weight of the cast iron blocked 360 would negatively affect handling. Unless you spent money on go-faster parts/mods you would not be adding a ton more power, and with the extra weight might find yourself actually slower.
As stated before, the Hemi won't fit in the Crossfire engine bay without major mods due to its massive width. In reality, Mercedes power is the best option here. Most powerplants will bolt in with minimal mods.
Whatever you do, please do not throw any of the garbage GM produces under the hood. That would be pure sacrilege, plus you defeat the quality behind Mercedes' legendary reliability. Throw that crap in the scrap bin where it belongs.

 

Hate to be the bearer of bad news but, pretty much none of the top three are made in the US. Most outsource parts to Canada, Mexico, China, etc. and assemble them here. Ever looked at the suspension stickers on a new Ford truck? China and Mexico mostly.

 

Feel free to UPS all those crap GM products to my front door.. Address is one PM away.. Headers to fit an Avalanche and high flow exhaust for same will be most welcomed..

Oh if you do go dodge.. think adapter plate instead of those crappy a$$ tranny's they make!

 

The first I had heard had me laughing hysterically. It was a car and driver on one of the newer charger's. I forget exactly what they said but it was something like: "...getting the American experience, and by American we mean an engine from mexico and a car assembled in Canada."

I damn near fell out of my chair laughing when I read it lol. I didn't realize they were all like that though.

Yes! Of course the last statement depends on a lot but that is basically true. NA-NA, easy. SRT-55K, harder but not too bad.
