If you had a CLK 320 and wanted to do an engine swap. Would you choose to use a CLK55 V8 NA engine or a C32K engine and why?

If I had your Japanese 320 putting out almost 270 hrspwr I wouldn't do a 32K. I would keep what I have. The difference doesn't justify the cost in my mind. If you want more I would do a 55. Ash would be the man for advice as you already know. How many miles on yours now?

Given those two choices, I'd be tempted to do the 32K, simply because I've never seen it. From an ease of install standpoint, the 55 would win. If you know someone with enough experience to assure it would work like a factory install, it's an easy choice. I'm a big proponent of "when finished, it should work".

I think you've done almost all you can do for a v6 already and I think it's time for you to play with a v8 n push that bad boy to its limit. Your big muscly arms are asking for a big muscly v8

I don't understand why a 55 would be an easier swap than the 32K.

My big arms Have you seen BigMike's arms? They are twice the size of mine.

There are a few more things I could do to my car like take it up to a 3.8 like CLKFan did, do a CF Crankshaft, and LSD.

Here is the data that I came up with

The CLK55 is 220 lbs heavier @3,485 lbs vs the CLK320 @3,265 lbs. I'm assuming that the extra weight is mostly from the bigger engine. So taking that into consideration and with the specs below it would seem the C32K would be the best choice which was put together mostly from Road & Test Stats and some from MarcusF website.

C32K
Horsepower = 349 bhp @ 6,100 rpm
Torque = 332 lb-ft @ 4,400 rpm
Readline = 6,220 rpm
Final drive ration = 3:06:1
Curb weight = 3,605 lbs
0-60 = 5.1 sec
0-100 = 12.2 sec

CLK55
Horsepower = 342 bhp @ 5,500 rpm
Torque = 376 lb-ft @ 3,000 rpm
Readline = 6,000 rpm
Final drive ration = 2:82:1
Curb weight = 3,940 lbs
0-60 = 5.3 sec
0-100 = 12.4 sec

The CLK320 being 340lbs lighter @3,265 vs C32K @3,605 lbs, I would assume that an engine swap would result in a faster 0-60, my guess it will be around 4.7-4.9 seconds and tuned even faster.

doing the 32K would be much faster and less work involved if you have a 320 but going to a 55 requires the following;
55 motor
motor wire harness
new trans
drive shaft
diff
axels
for the diff and trans you can use the trans and diff off of the 430s and it would work just fine and if you do that you can keep your existing drive shaft and axels as the 430 and the 320 share those two items and the 55 uses the trans and the diff off of the 600s which are thicker axels and the diff and the trans have 4 point contacts to the flex discs and the 320 and 430 have 3 point)
radiator
condensor
AUX fans
fan resistor module
fan blad
fan clutch
ECU/ME
TCU
MAF
Primary cats
secondary cats
exhaust piping

I did plenty more becuase mine is a pre facelift without tiptronics which i am converting to tiptronics. I'm also changing all the seals and gaskets as well so i can agve a brand new engine going in. with the 32k you get to keep majority of your stuff but you will have to either work the 32k ECU/ME in or have yours remapped also you will have to add an aftercooler in. I dont think the numbers about the 55 are right last i checked the 55 put out 368hp and 372 tq but i could be wrong. the 55 puts out more power than the 32k thats for sure and the torque is higher as well because after all it is a v8. if you are up for it the 55 will have much more upside but the 32k will be a great imidiate power gain and also with minor add ons such as puuleys you can gain some more power without doing too much mods. hope that shed some light on the difference.


to Sonny: I hope your doing well brother i heard about your accident. how are you doing man? wish you a speedy recovery.

sonnyhoang

Thanks ash, sorry don't mean to threadjack you big will but yeah I have some internal
Bleeding and a torn intestine but I'm ok! Should be leaving the hospital in the week, how goes your 55projext?

MarcusF

The reason I'm guessing the 32K may a tougher install is the ECU. If the ECU talks to the instrument cluster, it may not like the W208 cluster.

That’s one "guessing", two "may"s and an "if" - so I could be worried about nothing. It may bolt in and go without a hitch. If the ECU does talk to the dash, the R170 cluster may functionally be the same as a W208.

I really would like to see a 32K powered W208. A 32K powering a W208 with an ultra rare factory Sport package makes it that much more special. Couple that with the mods on your car and THAT is an event.

This mod sells itself.

its moving along man i will be posting the proress in a few weeks. stay safe and hope you recover fast man.

Interesting write up by Road & Track on the C32K and CLK55

Get Well Soon Sonny

That's very interesting because the same aricles from many other sources rate the 55 motor anywhere from 362 to 369hp. And that would also be the same motor that came in the CLK55 W209 and the C55 W203 and they are both rated higher.

bobbyjo9

the 55 in the 209 uses more compression than the 208 yeilding more umphh.

VIPclk320

very intresting, i thought they are both M113? how would raise the compression on the w208 55s?

bobbyjo9

Cut the block or higher compression pistons. Im not sure how deep in the hole the piston is, but id guess it's close to a zero deck leaving pistons as your choice. If your going the FI route though, you'll want less CR so you can raise the boost
