turboing a m111

[alhacker]

hello everyone, i have been trying to turbo change a m111 230 engine on my 97 c-class w202 for over a year now,i went to several performance shops and one of them gave me the following setup. for all u turbo guru's here ur help is highly needed and appriciated.

the setup:

1: the shop will lower compersion by using a custom copper head gasket, a set of diesl pistons and cromed piston rings.

2: fabricate a custom header for a t3/t4 garret turbo , use an upper mount intercooler.

3: add a 5th and 6th injector in the intake above the throttel body with a electronic controller

4: new timing belt and "reverse the vanos"

5: beef up the transmission using custom machined discs btw the gears

6: using a larger oil pump from a 230k or something

the shop expects 270 hp on the wheels?? any recomendations??

i am thinking of using a transmission oil cooler too and a spray system on the
ic...

plz what ever help and recomendations are highly appriciated

You could try a PM to get Mark300SL's attention. He knows a thing or two about turbos!

However I think the 230 was about 150 BHP na. I very much doubt you will get 270bhp at the wheels.

I always though that the W202 C230K was around 192BHP (assumingt that teh one on question is a Kompressor?)

How much is all this going to cost?

Sounds like a bit of a mission, even if it gets you 270BHP, a C36 has 280BHP (although not at the wheels) and a C43 has over 300BHP IIRC. Surely this would be a much more logical solution as you would get the benefits of better reliability, better braking system and probably a better suspension set up too.

I'd be a little warey if the particular business is trying to sell you 'timing' belt for your car

What's the cost of the conversion and have you had any insurance quotes for this?

Good luck,

Will

well the cost is very cheap compared to ur costs, i am in lebanon beirut, its about 3600 USD and this is a "rally shop", about the suspension i have sourced a set of koni's and got to find a set of decent big brakes... its not a belt its a chain my mistake...

No, he's talking about a C230 (never saw them in the UK I don't think).

4: new timing belt and "reverse the vanos"

VANOS? Errr...that's BMW's variable timing system, if I'm not mistaken. They'll be somewhat hard pushed to reverse it on a Mercedes then, I would have thought!

I would be very careful that the shop knows what they are doing
There are an awful lot of things that can go wrong with boost - I know
My choice would be to start with a 230k engine as its already designed to run under boostand is less likely to self destruct.
Finally - get a look at the diesel pistons and compare them to 230 pistons - they may be stronger but
1. the crowns could be a LOT higher - increasing compression
2. they may be a lot heavier
3. - do they actually fit the stock rods - and can the stock rods cope with the power?

Its very easy to guess a list of parts - its much harder to get it right
