So...
A set of extremely boring,forged OEM pistons for the Volvo B23ET showed up...



Heavier than needed,of "wrong" compression height and just....sore in general.
Nothing the idiot i am can´t remedy..
So..



Also got a hold of a "coromant" cutter for the lathe to cut the big end width of the conecting rods.

All in all?

Just the valve cutouts to be flycut left to do,and that´ll be taken care of early next week.

Schön,schön....die sollten doch in meinen Motor rein ..oder nicht...

Nice!
Sollte ich mal einen Turbo fahren, weiss ich woher der warscheinlich kommt

Btw. Jesper: Steht das M auf deinem Kühlergrill für Maki?

This is where we´re at right now.Remains to have the valve cutouts done-and that will be come early next week.



Piston is of very similar design of the OEM 16V.
As can be seen...a forged Mahle as well,only at 1/4 the cost.



Still run a 24mm pistons pin.This for load and longevity reasons.



With this setup the axial play of the conrod is controled at the crankshaft end.(see one pic up).Point being that up at the piston end...there´s room for movement-a´la the early design 16V.

Super schönes Bild Maki!!!
Welcher Kühlergrill issen das oder selbst gemacht?

[Nagilum]

Was ist das auf dem letzten Bild?

[Maki]

@max190 - Bin jetzt etwas irritiert!
Das ist der ganz normale Kühlergrill ! Wie kommst du darauf das da was gemacht wurde?

Nagi.
Last pic is of an engine mount.
Point is that the OEM 16V is WAY to soft to handle the torq of a souped up turbo engine.
So..this is ONE alternative.
It´s a transmission mount for a Volvo FL8 truck-and trust me...it´s a LOT tougher.
Other option would be to use engine mounts for a 300-24.That on the other hand isn´t approx 25 euro a piece.

Checking the crank for straightness,ovality and if its conical.
Turns out that the crank is completely ok efter a couple of whacks with the sledgehammer

[Racing]

Bit by bit then....


The stressplate we´ve made.50mm thick steel.There to be torqued down over the deck of the block while boring it out.Point is that it´ll "simulate" the forces on the block that the head bolts omit,and by using the stressplate we´ll get more cylindrical bores under load.
Important to any high performance cast iron block.



We made the cylinder holes 98 mm to even cope with any EVO blocks that might come in our way



The "Volvo"/Mahle pistons.
Now with their valve cutouts done.Will cope with 14mm of valve lift at 109deg LCA.Final polish to come though.
