    No bud, avoid Noelle. It's not worth 18,000 Euros.

    Get a blower, you'll be much happier with more power for less money.

    Ok, your right, but not on a engine with 200.000km, i think he will die until you Count 1-2-3...

    I´m still interested on a new block/engine with more capacity to get around +100hp, if possible?!

    Here i have more feed for the brain:

    I will take a 4.8L crank and grind the low end of it down from 54 to 48mm and then use a M5 E34 rod with depth gauge 144mm and Pistons must be speciality made to measure because of a new compression height!

    If i bored up to 94mm and have a hub of 94mm, then i get with it 5219ccm...

    Best regards, Ronald

    I mean in theory what you are suggesting could be done I just don't think it makes sense from a cost/performance perspective.

    Ok, this is possible, but if i spend 7k€ for sc kit, i have no new engine with it... Click here to enlarge

    There will be no Provider for a stroker kit in the US, that couldn´t be possible, or?

    Nobody knows something about it?

    The only one i know, is ppm from Australia, they said to me, send us your crank, rod and Piston, we will make a kit for you, but no pricing before for the whole kit...

    And what about manufacturer of forged Pistons which runs on Alusil bore?

    Best regards, Ronald

    Sure, this would works also i think, if i bored up the same to 94 i get 4.9L with it, but the 4.8L engine has different inlet manifold which gains 15hp and a other oil sump which also gains 5hp, here shown below.

    So i must do more to come over the 400hp, only changing crank, rod and Pistons wouldn´t be enough and with the 5.2L engine i got more torque in low rpm range, i think it was over 450NM at 1.500rpm, didn´t find the dyno results from Noelle´s engine, forget to save it at that time ago...

    I think your best bet is to get the parts from the N6248 and add cams a good tune from someone like Evolve. You'll get over 400 hp that way and it will be the most cost effective.

    You might even be able to find a N62B48 from another car and just swap it in.

    Yes, sure the best most cost effective, but not what i'm dreaming about to get "much more" torque in low ranges...

    Btw: Nobody offers cams for the N62, because of the valvetronic system, it's too complicate i think about adjustment later...

    Best regards, Ronald

    If you want low end torque why not a TVS blower then? More torque than anything else can hit.
