An I4 would cost more to do for sure. On that note, you've heard it from plenty of people in more than just this thread, there are lots you can do to the motor you already have in your car but you've obviously made up your mind so go get a cherry picker, rip out your 320 engine and throw a 230k in there. Then when your car has 0hp because it won't run, don't come on here and whine. That or you can trade it in so someone that will appreciate it for what it is can enjoy it and you can go get something else. After listening to that youtube clip, if you think that sounded good, I see a civic in your future. You'll find it's a much easier car to mod, it has a ginormous aftermarket and you can be like every other kid out there with 75 stickers and picnic table on the trunk.

 

You have a vehicle with a gorgeous body and an engine that can run 200-300k miles with reasonable maintenance. You want to jeapordize that for something that, at the end of the day, will be a little faster and a lot less reliable. Go ahead, but don't ask us which is better or cheaper because we don't recommend it. And if you have to ask "how much", you can't afford it. You might want to consider a beater WRX and mod the crap out of that. Then you can enjoy your XF for what was meant to be, a solid, peppy (but not quick) sports car. But it is fast -- mine easily breaks 140 before I run out of road/guts. PS-Yes, Audi's can be modded (I have a chipped A6 2.7T with >300 hp) but don't get those owners going about the cost of parts and repairs. The more power you make, the more frequently other things break. It's like bog-running in a jeep (another youthful passion), another expensive hobby.

 

just found and bought a SRT6 engine on carparts for 2700. cracked block and timing cover. I will replace them with my block and timing cover. Comes with supercharger, ecu and wiring harness. Picking it up next week. I shouldn't need any mods to the rest of my car to do that except for unlocking the ECU. I'm too into the looks of the XF to get anything else. If this doesn't work, anybody on here who has an SRT6 that is strapped for cash or cant afford insurance gas etc and wants to trade their SRT6 for an N/A plus cash, let me know. must be SSB, silver, or Black. Will consider aero blue.Im sorry if im pissing anybody off, but im not giving up on this. Every other aspect of my life is kept in responsible order. college, top of class, laser guided toward career, good health, bills paid, etc. I'm in a position where I can put alot of time into something and this is what I want it to be. Someday there will be a "well, he finally did it " thread. I'm not going to write off anybodys advice, but I plan to question it again and again until I'm sure on every aspect of it. Now Lantana also said that u should figure 1100 to 1300 on top of the engine cost so gotta figure lower than 2k to get an srt put in.

At least you're starting to sound a bit more reasonable. Before you put your money down do you know how the engine got a cracked block? Make sure nothing that is supposed to be on the inside is now on the outside Also you will not be able to use your timing cover because they are different between the NA and the K motor. There is quite a bit of wiring and other components that you'll need (IC pump, inter cooler etc.).

If you have a manual transmission then mating the K motor to the trans isn't a slam dunk either. But with that said we'll have one done before spring so it is possible.

Research, patience and listening to those with far more experience than you will be your best assets my young friend...

Best of luck to you and stay safe...

Sorry for asking this question in someone else's thread but the gears in my head are rolling know. I am new to the forum and really like the idea of an SRT6 engine in a manual N/A.
Will the manual trans hold up to this swap?

 

It is doubtful. Too much torque. This even before modding the SRT engine.

 

"anybody on here who has an SRT6 that is strapped for cash or cant afford insurance gas etc and wants to trade their SRT6 for an N/A plus cash, let me know. must be SSB, silver, or Black. Will consider aero blue."

Awww. I was already to trade when I noticed I had the wrong color.

 

the only way this makes sense to me is if there is more proven support for modding the 230 engine and they are getting great performance. the V6 is a great engine and mechanically not hard to mod. The issue is the MB electronics and how much trouble MB went to, to make the electronics hard to mess with. It is only a matter of time before we see more and more modding on the V6. I personally like displacement and the MB V8's are relatively light since they have alumunum heads and blocks. I think the I4 conversion would be very doable if that is what you want. I believe it would actually be harder than a V8 since there would be way more parts to buy and swap, while the V6 and V8 are indentical except for two more cylinders. I wouldn't do this unless you have a proven plan and recipe to get you where you want to be. Just keep in mind that your car is wired for a Bosch ME 2.8 and swaping in anything that wasn't wired for this computer is going to be very tough and you may not get it to start after all the wirring. even my n/a V8 conversion had a bunch of reqirring to do and the supercharged V8 has a lot more but at least these conversions use the right computer family. this is one reason I would not consider some of the other more exotic MB engines such the 63 AMG engine.

 

I'm still working on my 2.0 Turbo Crossfire...

 

Hey Rudy, is what he's saying true? And how do you do dual throttlebodies?

 

How's that coming? I'm looking forward to seeing it done!

 

Just playin "Devels Advocate" here, but wouldn't an engine swap out of a SLK 230 Kompressor be a fairly straight forward swap? As long as you got all the wiring and everything else you needed to go along with it.

 

I'm getting closer everyday, The first three weeks in December are dedicated to completing it.

Just about any motor swap is possible, just remember the rule of Pi. If you have never done it before it will take 3.14.... times as much effort, money, and time that you think it will. And if you have never done anything like it before it's Pi squared.

 

I'm confused, are we talking about motor swaps or geometry

 

This is probably the best advice in this thread. The problem with the Crossfire is that it's not a popular car to mod--at least compared with other european, asian, and domestic cars. This means, essentially, that every time something more than an intake, exhaust, and tune is done to this car, it's like reinventing the wheel. Asking which is harder to transplant in a crossfire, an I4 or V8 is like asking what hurts more: having your wisdom teeth removed without anesthesia or getting your appendix removed without anesthesia. Neither option is pleasant.

Seriously. Just buy something else. These cars, like all modern european cars, are overly complicated. It would be an electrical nightmare to get something like this done. This isn't like writing directions out for changing the oil.

I think the most important question to you, Tek-9, is why? Why are you so against just buying the appropriate car for your interests? Why not just an SRT6--they are among the best performance bargains currently available.

 

I think the trans will hold up. HDDP did this when he put an SRT6 engine in his n/a Crossfire which was a dedicated road racer.

Putting a SRT engine in a n/a is similar to putting a 55K engine in but slightly easier. since you can use the stock fan and shroud and exhaust bolts right up. You could have a problem with the flywheel as I it may have a different bolt pattern. If I was doing this, I would get the SRT6 flex plate and compare it to the n/a flywheel for balance factor and bolt pattern. It the bolt pattern is different you may be able to get it redrilled. You would also want to rebalance the flywheel to match the balance factor of the SRT flex plate. Aslo you would need a C32/SLK32 ECU as the SRT ECU cannot be reprogramed by the MB system since MB system doesn't recognize SRT ECU as it has a differenct part number which was never used in a MB. It may be possible to update the firmware of the SRT ECU to the SLK32/C32 version, but not sure. We are still learning what is possible...

 

I am going to do this the right way and wait until I can find a wrecker SLK32 and buy the whole car.

Audi or VW. Lots of go-fast parts and knowledge.

I put this in here only because they are a local company that unlike most things down here-is done right. There are a few RS4's running 400+ HP and my, my, my are they fast.

 

The new RS4 is over 400HP OEM, so I sure hope so

 

please leave the slk32 alone. screw your ride up all you want but leave the 32 to die in peace
