he is stupid i had a s14 with a rb25det before i got the z and had a build engine and spent 8 k on it including the turbo and put down 480 rwhp on it and trust me guy's it's not worth it . You have to take the motor apart just to weld a crank collar for the oil pump drive if you don't do that well the internals can take only 350hp anything above that is to risky .I had a z before i got the 240sx.I had a s15 conversion, wide body ,coilovers ,just too much to list and after all that i still missed my z .After all I sold the s14 for 15k and got my z and there is no way i am ever going to sell my z AGAIN.Since working on both the motor the VG has much more quality then the rb and better design .I know aalot of ppl say ohh you have to pull the motor to do anything on the car well don't you have to do that with the rb too and plus a stock vg can take more abuse then a rb 25det.
