Is there any intake manifold that would increase torque on a na b230 ? Why do some use a b21 intake?

Longer runners usually mean better torque but it all depends a lot on the camshaft they have to work with.
B230 style manifold worked best for me running K camshaft on na B21 with K-jet.
I used a crude "flowbench" awhile ago and compared 4 different manifolds (b21, b21ft (the worst), b230 and LH1.0) aiming for best high RPM power since that's what the K cam is for.
Mating the injection system with B21 manifold may be too much work for the torque you may gain.

You will want a head and cam combination that actually flows a decent amount before worrying about manifolds.
I picked up 14 whp with nothing but a intake manifold swap on my car, went from a b230 intake to a b21f intake

Im think your native word 'drehmoment' gives a better idea what we'ze after
Which is, like, 30% on an NA car.
Right, but the manifolds do not present a restriction on a 530 head with an emissions cam now does it, Opa Jan?
Id get a different ring and pinion setup over exhaust, intake, cam any day.
What gears do you have now?
I have 4:11 on a completely stock 245 and it'll spin the tires off the line like nothing.

Easiest answer is:
1)pull the head, and have a mchine shop chop about 060" or 1.5mm off
