D is Volvo's mark for piston diameter tolerance...goes in the cylinder marked D.

On the underisde, between the pin and the crown, there would be signs of a steel insert in the piston. If it's all smooth along the under side of the piston, and if the skirt is really thin, then it's forged. If it's got a thick skirt, reinforced-cast.

B23ET left, B230FT right

Notice the skirt thickness

Hey Mike, did you compare weights of those guys? Actually, that's not apples to apples is it- how about b23et to b23f or e pistons? Hmmm, still not really apples to apples...

Just curious, I'm using the ET's as well...

Yes. The B230FT felt heavier. Thus ends my weight comparison. I believe the ET's weigh in around 610 grams. I'd imagine the steel lined pistons would be heavier. Hard to believe the "light" one could be that heavy.

see www.pukema.com for the turbocontainer project.
they got around 450 hp out of a B23ET, they used stock rods, stock pistons
IIRC it was a 11.5+ second car..
