ITB's on an Rb20det

[specialedition]

As we all know. Rb26's have itb's. Im thinking of installing them onto my rb20det and so on. Has anyone here done this before and what needs to be done. Id like to incorperate this into my build on my second motor sitting on my work bench. Thought it might be a cool idea.

Your looking to install rb26 ITBs on a 20? Intake patterns are not the same. Or did you mean make some custom ones or adaptor plates?

you'll need adapters. though i haven't seen his old car, he said he had adapters made

To get the port shapes without using a 5 axis CNC machine for porting heads (it can measure ports accurately via digitizing ports and cut them out on a piece of metal), could apply some die or similar to RB20 flange on head and on RB26 intake plenum flange and press onto adaptor plate. Then drill press the holes, port adaptor plate until you get the shape of port you you want and drill mounting holes, tap holes to get screw for mounting bolts. Saves removing head, etc.
