A question for the guys manufacturing sump adaptors to fit the RB30 block into a GTR...
Can you redesign your adaptor and pickup to fit a RB30 (VL) sump onto the RB26 block...??
The basic pattern would be the same and it could be a lot lighter as it won't have to carry the stress and torque from the front diff.
It would also allow me to use something like a Hi Energy sump.
I have seen the amount of work involved in modifying a GTR sump to remove the diff, etc and feel a nice light adaptor would be a tidier and cost effective alternative if the 26 was going into a Skyline.
The reason I ask is...
I have an R32 GTR and also a VL wagon.
The plan is to build a stove hot RB26/30 for the GTR and put the RB26, from the GTR, into the VL. The motor I have is relatively stock and has done less than 10K on a full rebuild so I don't want to pull it apart. It would suit the VL chassis nicely with just a few tweeks.
The money I would spend extracting good power from the RB26, if it stayed in the GTR, can go towards the new motor.
I only have to build one motor to have the best of both worlds...
