Would you be doing it via the crank and liners or via an ally block? I believe Mark Shead has done 2.3 and it is supposed to be amazing and a real torque monster through the whole rev range. It is worth checking what turbo too.


In theory a std 2000cc with a modern borg warner EFR twinscroll and manifold is brilliant for torque (my std engine made 500 ftlb) so you may not need the long stroke as they make big torque very low down in the rev range.


The long stroke will make the turbo spool even better though as bigger exhaust gas. I am considering it when I get Mark to do my rebuild, it would be an easy 580bhp on the next EFR up in size.
