B21f intake manifold swap - What?s involved

Older pic, no longer have the Heineken can heat shields, also different injectors. I use the k-jet o-ring on the bottom of the EFI injector.
 
I made my decision based upon PM interviews with 3 folks who converted from the B230FT to the B21F; 2 in Europa and 1 in Canada. The only dyno data I've seen for the B21F (E in Canada ?) showed a brilliantly flat torque curve, as opposed to the peaky curves I've .

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

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.
 
Question type of K-jet

Hi all,

is the manifold from a B200E the same as from the B21F?
Cuz I'm reading when it's from a B21FT it's no good (bad flow in runners).
On (old) pictures I can not really see the differences

B200E manifold:

That pictures shows the b21f manifold so it is the same.
