But with just dropping it in and leaving it be, what about the RB25 written on the cam gear cover?

yea the 25de are like 15mm bigger and usally 2pot(r33 anyway), but if your car can stop with a 20de im sure it will be fine with any rb motor :D

any way isn't brake size meant to suit the weight of the car not the power?

No... stopping power required depends on weight X speed - but there is no formula - it seems to be a pretty subjective judgement by the certifier.

lol no it's not, you can't tell me that the speed limiter kicks in at 100kmh :p
You don't need to be  going over the speed limit to stress your cars braking system,. I can think of several roads around the bay of plenty and surrounding areas, that will give even up graded braking systems a good work out, all without braking the speed limit.

The R32 RB25's have plain "flat face" cam gear covers unlike the stamped RB20 type. The cam shaft covers are the same and swaping coil cover from the Nissan 2500 one to the RB20's one will hide it all.
I thought brakes on  a R32 RB20DE and R32 RB25DE were the same. Both use 4 stud.  Its the R33 RB25DE that have two pot fronts and (4 stud) larger rotors (R33 RB25DET's have 4 pot calibers front and 5 stud larger rotors still).
Really just swap the 2500 coil cover for your original 2.0 one. Life will be godness.

R32 GTS25 brakes have the same diameter rotors as a GTS-t, difference is theyre 4 stud and use cast sliding calipers as opposed to the Sumitomo 4/2 pot alloy calipers on the GTS-t. R33 turbo brakes are the same size as R32 GTR and use the same Sumitomo calipers with extended brackets.

Also, GTS25s use the same diameter exhaust as the GTST and M-specs also have factory swaybars, at least this is the case with mine.

The motor should be a case of drop it in, plug it in, change ECU and go, just remember to change the spigot bush in the crank if your car is manual and your new motor is from an automatic :)

Sadly not all the GTS25's have the larger exhaust, it was an option, it's pretty much only the S spec ones that had and the rear sway bar, they also had a factory fitted LSD along with Hicas,
