Compare it to the expensive Jap stroker kits and it would be relatively cheap. Also, I guess if the local kit was made in significant numbers, I would imagine that the cost would be significantly lower.
Custom crank, SR20 rods, custom pistons, sleeves, spacer plate, block mods to suit. Better RS ratio than an RB30 and would rev to 9K+Also, I have heard of a Sydney workshop that has used a modified RB30 (or was it an RD28?) crank in an RB26. Also, Risking have an "RB29" kit usng the RD28 crank with 87.5 pistons.
