You sound pretty new to the game to me!

I've been in 335 and raced E46 M3s and G35S and etc and it lost to all of them in stock form. Its not slow... its just not as fast as people make it out to be. manf specs are hardly accurate in the real world.

Not saying a c36/c43 could beat it in stock form, but with the right mods and weight reduction, shouldn't be too hard to achieve

has anyone tried kleemann headers for the c43? kleemann has a dealer inside a HUGE mb dealership here in atlanta that has a set for mercedes 4.3 v8 hanging on their wall ready to be sold... i think those headers are supposed to be good for 20hp, maybe an intake and chip with a highflow catback exhaust and the c43 would be given a fair chance against other $60k in the modern +10 year arena.

e36 anything is pretty much not even worth talking about especially since they castrated the american e36 m3 so much (i believe euro version pushed 300hp)

also, i COOKED a g35 off the line and he never came close to closing any gaps last week (he had problems getting traction) so based on what i saw people shouldnt be making up stories about some pos 350z pulling away from any 335's.

are people using numbers from the 2-door 335 or 4-door... it would seem only fair to compare the auto 4-door to the c43....

word on C43 tranny's being ****. my 4th gear clutchpad went out on tuesday and i had to spend some serious money to have my tranny rebuilt. luckily i knew the guy who did it so he did a good job and hooked me up on price. paid less than half of the stealership's 6500 quote on the tranny swapout (for a rebuilt one at that!!)

OK 335i's now modded are running high 11's.


Stck ,a 335i can run low 13's. If you can get a 4.3L N/A C43 to run low 13's without F/I ,u r the man! You would also be teelling me that you could get a C43 to run like my car. I think not!

You guys crack me up

This thread will never end at this rate.

Sooo many variables that a keyboard just can't work out. Line em' up, get video, and post em.

Hell, I've nosed ahead of a couple 911's, C32's, and vettes with the C43K, but I've also been spanked by a neon with a huge turbo, that kinda sucked....you just don't know until you try. Enjoying this thread though.

There's a big difference between a blown C43 and a N/A one! it would be complete heresy to hear someone with a N/A c43 say that they beat the above.

i agree when people say bmw's are easy and cheap(er) to mod. but those same people should be committed to an institution if theyre going to start talking about modding a 335 which is pretty much as tuned as it can get... 300hp from a 3 liter inline 6 is starting to get to the point where serious money is needed to make noticeable improvements in power and hence speed. what im basically trying to say is that take a stck c43 and 335 with a 10k budget (same mechanic) and the c43 is likely to come out ahead... the above would certainly not hold true to a e36m3 and certainly not a e46...

C55 - how much hp is your 55 running? you put headers, chipped, underdrive pulleyed, intaked, and exhausted the car right?

Oh for sure, I think I missed the point...stock my car was way different. Couldn't have pulled off the above back then, no way. I guess I just kept reading all these scenarios and was thinking that I wouldn't say it unless I saw it.

It would be nice to see a video of the two in stock form go at it. Im sure there will be one at some point.

I have no pulley's but I do have the other parts you mentioned


However it would cost one more $$ to mod the MB vs modding the 335i for the kind of power and trap speeds I'd like to accomplish in my Benz. There is potential hp to be had in the BMW 335i compared to how it comes out straight from the factory. The mods out there now have these cars running high 11's in the 6 speed and low 12's automatic. It is cheaper to mod the 335i is the truth!

damn... well screw that! what about the 55 kompressor motors? are those plug and play in the w202? would that get you the low 12 time you desire?

No the kompressor motor is not plug and play unfortunately.

ok so which motor is it that you use for the 55 conversion. is it the 5.5 found in the non-supercharged e55 w210? is it possible to add a supercharger to that motor? maybe aftermarket renntech of kleemann?

i have 4k into performance so far..

Yes,Yes and Yes!

how did you supercharge your car with so little money. most kits are like 10k arent they?

i tried to go up against a shelby gt500 (2007) in my c43. the driver denied me the race. (i thought it could have been either the 350 or 500, and an inexperienced driver on a 6-speed can really damage the 0-60 so i thought i might have had a chance vs the 350) he claimed that his car would "kill" mine. i proceeded to inquire how much hp he was running, he claimed 520. i told him he was out of his mind 450 max. at which point i was still denied the race, my spirit was a little damaged, im becoming more obsessed with the c55 conversion. i want to hammer out people who think theyre tough in their american muscle cars... damn shelby, at least ive got a couple g35's in my pocket and a recently shot down 740i...

so what do you think the max hp a w202 v8 can push with currently professionally available products... including plug and play type engine swap with accomodating upgrades applied, including supercharger

Nice story but thats all it is. Maybe you're one of those folks that take off without warning and get all excited when your infront and their not passing you haha . A 335 will walk you regardless and with mods you don't have a chance sorry. And what about that S500 vs 335i that had me for like a week get real people. BTW the auto is faster then the Stick so if it was an auto its even more less likely.

as i stated i actually requested the race, hence the verbal interraction, i dont really take off without warning and get excited when im ahead. i only consider it a race if the other driver and i are mutually racing. and youre pretty much retarded especially because you own a 335 and cant even check the numbers on the bmw website

PerformanceDrag coefficient 0.30 CdTop speed1130 [150] mphAcceleration 0-60 mph – Manual transmission 5.4 secAcceleration 0-60 mph – Automatic transmission 5.6 sec

good job. so a c43 that can typically do a 5.9 0-60 has no chance to keep up with a 335i sedan automatic.... i dont know is .3 that much of a diff? at some point in time the mb may overtake it at higher speeds.

dont come back with your posh opinions and unfounded observations and think you are credible because you own a fleet of german cars.

So you think that the website numbers is all there is to it huh? 0-60 is all you need to win a race ? A tuned auto 335 can do 0-60 in 3.9 seconds it's been proven on GPS but that doesn't mean it's going to kill a Z06 to 100mph you claimed it you ran to 140 I gurantee if the the 335 driver was even driving properly you wouldn't have had a chance.And I'm tuned but I'm not even talking about a tuned car.

NEVER!

LOOK! BRO! Your stck C43 is not running with any stck 335i,whether it be auto or stick,unless you do the mods that Speedy Benz has on his car now ,which he was also using on the 4.3L motor that he had.Bottom line.
I don't understand why you think that the C43 N/A Stck, could do so.

You need to do much more research on the 335i. Wanna have a mid 12second car,then S/C your C43.

i didnt say it could do so or WILL be faster. im just wondering what the 50-70 is on the 335 and other similar tests. i mean, to say that one 300hp sedan has "no chance" vs another 300hp sedan is just an alien concept to me when the claimed "faster" one weighs more stck. the c43 should be able to keep up at a couple car lengths why not?

also, im not sure if s/c is the best upgrade option, wouldnt the s/c compromise reliability by raising the compression ratio? wouldnt it be easier and cheaper to do a 55 swap from a wrecked 55amg car?

The 335i which has been said many times, has a hp figure that's underated by the factory. It has more than it's published HP of 300.
Stop the magazine racing dude. Goto the E90 forums and do your research.

The ease of a 5.5L swap v S/C your 4.3L would depend on finding a motor for a good price,or finding an HPS kit for a good price. If you can S/C the 4.3L motor ,that would be easier IMOP. The 4.3L could handle the stress of low boost no problem Ask Nitrogen Balance and Silence about their findings on their S/C C43's.

Every answer you would need,we have been posting here for years b4 you joined. It's there bro everything,5.5L install,what's needed and what's not needed,and the HPS S?C installs on the C43's.

PS. No you will not have to reprogram your C43 if you drop in the 5.5L motor. It's plug and play.

You do that and you'll murder a stck 335i all around. Until it get's modded to run low 12's of course.

My neighbor got his in on Thursday. He has to do the break-in procedure now. I told him that we needed to line up and then we can do a comparison run and see how close or not close it is. Mine is completely stock and his is completely stock with manual tranny.

In regards to the inline six already being pushed to the limit stock...

That car has so much potential built into it. Without looking into what is available, I could see 450 bhp being feasible without doing anything too extensive.

damn bmw and their really good inline-6 motors! i liked the inlines from my c280's but they were so unreliable with those damn head gaskets!

HG was a factory flaw though, once sorted the M104 is a hugely reliable motor.
