That same Nissan engine above is what I would like to experiment with using the same Laminova cores that Matt has used on his.
My idea though is to build them into the intake manifold after slicing it like a cake (thanks Matt) and building a new plenum to keep them on the side of the motor not over the top of the rocker cover so access for maintenance isn't compromised.
Below is pic of one built by ARE here in Oz of the same engine but using a very special water to air I/cooler core, it worked very well by all accounts but regular maintenance means the removal of the intake manifold to gain access to injectors and glow plugs.
I would like to keep my Laminova cores in the curved section of the plenum even if it means increasing its size to accommodate them.
Regards Andrew.
