you could go to needswings.com for performance parts for the limited,,just don't expect much increase in power. jim

 

What's the average fee for V8 transplant?

 

The easiest conversion seems to be the 3.7 M112 from the ML350 W163 from 2003-2005. Straight swap (minus a fan clutch swap). No wiring needed or custom work or anything close to it (from what I have read). I plan on doing it in the future. The motors are super cheap at any junkyards. Extremely doable and cheap swap. One of the cheapest ever for a car.

This car in non-srt trim is not made for drag racing. They're not easy to mod for straight line speed. Buy an SRT6 for drag. The N/A is a tiny gt sports car with more grip and better weight distribution. The SRT6 is a tiny gt muscle car with power. To put a supercharger or turbo on the N/A you need a full stand alone ecu set up.

 

what he is not telling you is any srt 6 will be faster, get better gas mileage than a 3.7,, your V6 is a 3.2 ,, so yea go from a 3.2 to a 3.7 if you are going to swap do it with a 5.5 SC motor, on the aspirated 5.5 mercedes engine (non supercharged) a modded srt6 is still faster.
the fee would run what all you want done to the car, but average i would say close to 22000. engine tranny, brakes, new tires and about two months of good weather,, when my next one is finished,, gray srt ,,, turn key ready to drive 25000 that includes the car. no trade

 

The 3.7 swap is literally bolt on. The v8 is not. I was pointing out that the 3.7 is a cheap alternative to keep the weight distribution and curb weight of the car intact (to preserve it's sports car grip and nimbleness). The V8 won't keep the weight distribution intact and it will require a lot more work and possibly 5 to 10 times the money. Of course, if you want straight line speed and have a lot of time on your hands do whatever you want. The v8 will always be faster in a straight line. ABSOLUTELY. No one is stupid enough to doubt that. Personally the 3.7 would be enough for my daily driving. I had enough speeding tickets and trouble in my early years.

 

I agree with some of the things you say,, the 3.7 bolt in and the 5.5 is about the same amount of work,once the needed part replacement on the engine is done, which is done with the engine is on the stand one thing both engines has to be changed is the oil pan to clear the steering. oil pump to clear the hood the only and best part is the 3.7 is a cheap engine the best thing to do is but a srt6

The specs of this motor are all over the place depending of the model. That's without any bolt on and tune so it's still a considerable upgrade to any n/a for a mere 550$ CND bolt in with no extensive work involved (again not worth it for drag racing, for drag racing buy an srt6). From what I have read it's the same oil pan. The fan from the 3.2 is the only thing that needs to be fitted to the 3.7. There is a lot more work involved with the v8 swap. It's not a weekend affair like the 3.7.

I know the specs of the SRT6. It's still heavier on the nose as would be a v8.
