Th OP said they liked the look of the b230 manifolds so I thought this was what they wanted.

LOL. No problem here but some of this was done 10 plus years ago and I’m way behind.

Mine?

Man I had that thing running sweet. Was even nicer when I swapped out the huge T04b compressor for a 60 trim T3- boost came in even sooner and gave up little on the top end.

Indeed! Looked near ideal. What trim did you have in the T04B, perhaps the Super V or S?

Looks identical to mine, a Nathan conversion. I didn't bother to polish the casting, just painted mine. As soon as I get my 57mm TB rebuilt, she'll be installed on the 940.

Started polishing and never got back to it. Polishing is a lot of upkeep but on the b21f it's fairly easy. Painting is better and ceramic coating is really the way to go. I think this is nearly if not as good as Nathan's sheet metal manifold in my mind because of the long runner up to 5500-6000 RPM. The intended target(Red 84 242 B21fT) was hacked with MS1 when I got it.

Not sure I knew exactly. Based on measurements I think I figured it was an S trim. That thing would have made serious power if LH could have provided more fuel and rpm. I had the cam advanced several degrees to bring the peak down as well.
