hi guys what a thread!! i have a mid level drag gtr last time out i blew a side out of the block(to greedy with the nos) so ive been thinking about building a rb30 baised short block as a temp replacement untill i can get the funds together for another full counter bottom end so i have a few questions is block flex a problem at higer outputs? if so anyone maid a stronger crank/block gurdile? if so was it incorperated into a 4wd adapter? how hot do they run with a filled block? as my 26 head/cam setup makes maximim power at 9500rpm is there any way to make the things rev anyone tryed a rd28 crank in a rb30? is there any way to work out the first/second order hamonic vibrations on a crank(rd28) will my rb26 ati harmonic balancer work on a rb30 or rb30/rd28 hybrid? is there anything else i need to know about the rb30 in extreme power aplications the general idea is to use a rb30 early block(iv been told they are a little stronger correct me if im wrong) rd28 crank with some custom rods and a set of ross rb26 pistions i have lying around what do you thing it could rev to (not paticulaly safely) the donor rb26 has the following specs gt42r nos six port flogger hks manifold trust drag spec intercooler geady plenium 50mm x 6 thottles full tomei drag spec head extensive porting tomei drag cams 280 in 288 ex 11.25 lift ti buckets/retainers big valves/springs ati damper os tripple clutch/flywheel(will it bolt up?) motec m800 we were running 2.5 bar in a filled rb26 group a block will a rb30 block take this? anyone give my trust dog box a chance with the extra touge? am i playing with myself with the rd 28 crank idea would i be better to run a rb 30 crank and use smaller cams and only rev to 8000? thanks in advance
