If you are serious. I would forget what you read an go out and buy an rb26. get it recoed with either N1 pistons or forgies if you the budget agrees. put some 272 cams in and twin 2540R turbos or a t78 and your done big cooler power fc rb25 det gearbox metal head gasket, and spend some cash on good drag suspension.
it will run all day on a set up like that.

a good rb25/30 will cost you 10 15 k easy and they arent as reliable.
there is a guy in qld with a r32gtst withan rb26 and he runs 11's woith only boost.
