The 4.3L block is smaller and different than the 500 and 55's blocks. You cant bore it much more than it already is. Every tuner that builds these motors start out with at least a 5.0 V8.

Makes perfect sense to me!

mkb gets the same power out of a c43 as they do e55, so i figure by their numbers its all the same....

My friend,you're still not quoting prices for each and every one of these setups! Show us!!!!

Every 4.3L motor that any tuner increases displacement on they never use or keep the same block/head. The only thing really to do to get some power out of the 4.3L is to supercharge it. Even then, you'll still be getting smoked by stock 55's today. I have access to some of the take outs on the 4.3L motor, so I know 100% forsure that they are never used when a conversion is done, plus they're not really worth buying either. Anyone who plans to get themselves into a project like this would more than likely go a different route.

That's one of the most assine comments I've ever seen posted on this forum.If you think a C43 "supercharged" , which would give it 430hp - if done by Kleeman , is going to get "SMOKED" by a STOCK C55 - you're

Whos talking about a N/A 55. Thats old news. Im talking about the V8 KOMPRESSOR's.

I figured if it doesn't bolt right up with some work, then I will let it go, But according to jeffry it should be ok, he is working on cleaning the motor right now. If it doesn't go then I will have to go for an 03 E55. I just find them too heavy. But they are very nice looking cars.

If it does not wrk,I'm interested in the motor! The E55 is still a beast!!!!

I saw your signature that says: Silver 98 w202 C43 to W202 C55 5.5L conversion. 13.39@102mph 293whp/307fttq


How is that you converted C43 engine to C55 and get 293hp? Isn't C43 302hp already? Isn't that downgrade? Maybe I misread something..

Thank you

It is rear wheel hp...

L O L ...best answer yet!

Cool!

Hi Folks,
How hard is it to put thee55 mototr onto my 1996 C36?
Or is it even possible?

Regards,
Eddie

Same exact difficulty as if it was a 280 or other. With the 5.4L in a C43, you take out the engine -- if your 5.4L has no external ancillary components as mine didn't, you strip your 4.3L motor and put eveything on the 5.4L motor -- then you drop in the 5.4L. The ECU even works adequately unaltered. You do get a little more flashing the ECU with a 5.4L program (you just need the right tools). With the C36, you can't use your ECU, fuel system, ignition system, you'd need to adapt the front end of the exhaust, not sure if you can use your tranni, you'd need to change the motor mount locations I believe, more. But hey, people do V8 swaps into 190s ... so it all depends on your skill level and how 'fearless' you are. I will say though, if you have to ask you probably shouldn't be thinking about it...

I would stick with either buying C43, or keep the C43 you have. Like the HITMAN C43AMG calls them, Frankenstein cars will always give you more trouble than a stock (if same driver drives them in same conditions). And believe me Frankenstein owners don't complain out and loud if they have a problem, cause of pride!! They will not admit it...
I guess it's a fair game.

That's my 50 cents (with some solid experience)

c55 engine here for those who are interested. no affiliations.

I'd love to get my hands on that! Anybody interested in mine(5.5L) ?

He's better off doing the Jeffrey kit to his present straight 6.He'll make very good pwr with his present engine with an F/I kit.

You got that right. For anyone wondering about what Carl's saying, have a look here ; click each pik to get to the next.

OT... P.S. Carl, you see my 'new car'?

lol
