OK Im new to this High end luxure car stuff, (more at home on my Harly or in my chevelle) But I dont or havent seen any of the typical performance stuff here. so if yall bear with me maybe Ill learn something.

1. How well do the heads on the M112 breath? Are they port and polished from the factory? can larger valves be put in with out shrouding them to much?

2. is the block on non forced air induction nonAMG engines the same block as the forced air induction AMG engine

3. Stroker kits? Is the 3.5 just a bored/stroked M112? can it go bigger

4. How many CPUs/ecu/tcu ect. are on this ride and can the function independetly?

5. are CPUs programable? OBD1/ II?

Ohh I have soo many more questions lol Im reserching on the web and on this sight the same questions. If I buy this car tommarow I will also buy 2 engines and an auto trans to build and start experementing with. Ive Buil 600hp natraly aspirated engines and built PG tranys for em so anyone who has guidance in this new venture for me please lay it on me.

Thank you
Rick

I only know answers to 2 and 5 for sure:

2: yes, same block, but different internals.

5: The ECU is reprogrammable, but AFAIK all the software to do so is proprietary, and you have to pay to have someone tune your ECU (approx $600 to $1000)

On Question 1, I am pretty sure nothing on the engine is ported and polished.

I love this site and it's SLK info and SLK "socialization", but the real performance details for the M112 engine is in the Crossfire forums. Crossfires use both the normally aspirated and supercharged M112 engine. The Crossfire guys do lots of engine mods and go racing (plenty of 1/8 and 1/4 mile results posted on their forums).

Hell Yeah!

Dilligaf, I can't answer any of your ?s but just wanted to wish you luck if you decide to go ahead with this project. I hope you'll post your progress as you do the work. I've been contemplating a swap/custom turbo combo but everywhere seems to be a dead end as far as guidance and/or suggestions go. Not to mention that I'll have to pay an arm and a leg and possibly my first born to get somebody to do the work! :Beer:
