the rb30/26 hybrid is definetly the ultimate motor if u dont ever want to worry about anyone ever touching u. i read an old modified magazine article about a guy that had an R33 gts-t over here in the states and he did that motor setup and was running 9.4's at like 150mph and he still drove it on the street. absolutely ridiculous power....ur definetly lookin over 10 grand to have a motor like that built tho lol. i think secret services should try to see how far an rb25 can go on a stock bottom end like they did with their 539 hp stock block sr20. id bet u can make 600 . cmon ss!!! i was considering that motor swap but i need something that gets good gas mileage for college so i got the golf. my friend has a 240 tho and maybe i can convince him to do it. keep on boostin
