hi guys, i found someone selling their rb25dett T-28's. he says it bolt's right on to the red-top T-25 manifold (unlike the s14/5 T-28's)

is this true?? will i have to modify the oil and water lines, or is it a total bolt-on affair??

aside from the flange compatibility, are they actually the same spec T-28's as on the s14/5's?

thanks
J.d
