YOu can get a only rwd six speed tranny from the neo-rb25 out of the rwd r34. might as well just buy the whole set that way you can take the head from the clip and the tranny and sell the short block.. But iam not sure if the r34 neo-rb25 head will work on the rb30 short block i believe it has to be r33 rb25 head or rb26 head. Non the less you can get the rear whell drive tranny in six speed but will it last with that power who knows?? good luck and if you do do it post some pics.. oh yeah you r also going to have to raise the hood or get a shaker style hood to make it fit as the rb30 gains displacement by more stroke therfore it is taller.
