Not trying to be an a$$, but did you try to talk to vadim first about your concerns before posting this thread?

Vadim @ FD

We are not adding any stroke. I wanted to move down the rings so top can withstand more pressure.

MRAMG1

Thanks for the clarification

See yeah

Hey Vadim,

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.

MarcusF

For a factory M112/M113, at no point does a block exist without the sleeves. One reason sleeving them is iffy, is because they’re not pressed in.

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.

MarcusF

Correct. Per the press kit, OE M112/M113 piston side surfaces are coated with an iron particle reinforced resin.

Every 4 banger alum block I've owned has not had sleeves in them (and all were turbo'd from the factory)-and I had few issues with the block itself (wrist pins, rods, oil,turbo-ect).
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!

hooleyboy

We are hearing numbers of like 700hp you would think you want some added protection at such high HP.

rockjock

I've tuned evo VIII and IX's (granted-its a 4g63 block) but even the new Evo X's are seeing mid 500's to the wheels on a new and "untested" alum block and head config running 25lbs of boost-and I've seen so many b16 civics running retarded amounts of boost (to the front wheels....I just dont get that) w/o sleeving
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.

Thanks Marcus. Very informative...

AMGSC

Until??

AMGSC

Hopefully with VRP/Powerchip behind the tuning, the Air-Fuel, Timing, etc...will be optimized to prevent detonation.

AMGSC

Things are now picking up. Attached are B/4 pics. Entire engine block was rehoned and now the assembly process begins. We are in the final stages. After pics to follow in a day or two.

Transmission I believe is alread completed.

rockjock

In my book...you're not trying if its not breaking
Good update-who did you have rehone the block? Just the head surface?
Looking good!

TemjinX2

looks like its coming along nicely.

AMGSC

Things were moving slow but now picking up pace. Vadim should start full installation once the rod pins are in.

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.

AMGSC

Will easily withstand 30+psi of boost with the proper tuning.

Pic is located here.

AMGSC

Here is what Vadim is replacing my CM30 with. It flows 4x better than the CM30 and is designed for coolant, not just water so it will last forever.

c32AMG-DTM

Once the pump isn't a point of restriction, more flow doesn't equal any incremental gain AFAIK. That said, it sure looks beefy!

Is there an ETA for your car to be up and running again? Looking forward to your results.

AMGSC

Further improvements to improve suspension, trackability and dragability....

AMGSC

Here you can see a new Ross Racing Piston fitted inside the re-honed Cylinder Wall.

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.

rockjock

Nice looking end links-keeping with the PSS9's-or upgrading those?

spr

Polishing the beams removes the casting flash and does strengthen the rod as it thereafter has uniform sheer strength etc.

AMGSC

Per Vadim, these are not adjustable end-links from Code 3. They are control arms which cost me 10X more. Are you saying they are the same things as the ones Brandon is selling for $170? If so, I need to give him a call ASAP.

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.

NitrogenBalance

It's possible you are changing all the contol arms from the dogbone OEM units. In that case cost would trump a single set of adjustable camber arms.

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....
