Old vs New Piston Pics
Thanks again and sorry I appear to be doubting you. I should bite my lip before I ever question you but your input sure is good sensible advice for me and these forum members who are doing extreme mods like Blackbenzz, Hooley, mb_c55_guy, Alumnar and a few others...
Aren't the majority of aluminum engines (including ours) produced today sleeved from the factory? I seem to only recall an early Buick [I think] V8 that Rover ended up purchasing that didn't use sleeves which wasn't a good design in the end.
Mahle is the supplier of Mercedes-Benz Alusil sleeves. Alusil is a technology that's been in use for almost 100 years. To make an Alusil sleeve, a high-silicon content aluminum alloy sleeve is dipped in an acidic bath. The acidic bath etches away the aluminum on the outer surface, exposing a very hard, very long-wearing, silicon surface. The Mercedes-Benz M112/M113 press release says the sleeves are cast first, then, rather than being pressed into the block, the block is pressure cast around the sleeves. The outer 20% of the sleeve melts, bonding with the block. That's why the release says the sleeves are 'an integral cast-in part of the block'. So yes, the M112/M113 aluminum blocks are sleeved from the factory.
Vadim-glad to see you take all this in stride-there have been some "interesting" comments made on here-I kinda look at tuners as this: Pick one-have faith/luck that they know more then you (that prob why you asked them to do the work) and trust it until it fails.
Props for a good build!

I think the set up that he is working on (yours too Holey) is safe w/o the sleeves-balance and blue'd-with the right supporting mods (fuel del., ect) you should be okay-my $0.02.

Transmission I believe is alread completed.

So does anyone know how polishing the rods can actually increase performance? Vadim tells me it makes the rods stronger and prevents cracks to form due to the high-load stress. It also supposedly makes reduces the friction of the rod movements.

Is there an ETA for your car to be up and running again? Looking forward to your results.
The car should be ready by end of this month but it still needs a 500 mile break-in period before the boost is applied and ECU re-tuned to support 20+psi.
Edit: I just took a look at the diagram and it is clearly not adjustable end-links. These are stronger control arms that will allow the car to launch hard without breaking them.

That motor sounds like it should be great!
I remember first seeing your car at HOP with Mario and Josh when you had it dyno'd post HPS. You probably don't remember taking me down the street for a taco break. Seems that alot has changed for the better, you unlucky gen2 guys. Sorry to bring back memories, but looking back what a story/project....
