rb25 block + rb26head - info thread

[N I B]

There is more to it than you guys say and the valves are all the same size.Solid kit costs $770.I do use the factory manifold on the GTR but fit a single throttle body and billet blocks in place of the 6 butterflys.Please dont get affended as some seem to be as i have done a lot of R+D on this and have been very happy with the results both on my dyno and seat of the pants.

i was thinking of doing a similiar thing by putting the 26 head on the 25 bottom, then stroking it to 2.7l and working it to a 2.8l or 2.9l. what do yous think of that? it turboed of course
