so the only connection n america has had with the newer 731 head is in the e21 323 - so if these are exactly the same then I can actually order one from here brand new at metric mechanic - so now onto a few questions if you dont mind....
from what I understand, there is not much to be had also the max power is still under the b25 stock ........ this including putting in bigger b25 valves, reworking the head a bit etc and then the tb followed my intake/exhaust and ecu tune. The one issue I am foreseeing is the gasket ........are both the e30 320 and e21 323 exactly the same??? it would not be too costly if I had to get it from the uk but am curious.....thank you very much for any information shared
without touching the bottom
, what else is available up top??
