Rb25 For My 180sx Rb25 Question.

[toxsickcity]

hey aussie fellas,

First i'd like to start by saying hello and I am new here.. I am known at the nissansilvia forum as same username...

I really need some help with some non ca18/sr20 engine questions..

I am going to buy a rb25det on tuesday in bangkok.. yeh I live in thailand, but born in melbourne!

I really need to know what is the stock turbo on a r33/r32 rb25 engine. is it the T28?

has anyone here tried a twin T25 on a RB25det to make a RB25DETT

or what about 2x T28 turbos on a rb25DET to make a RB25DETT with 2xT28

anyone know of how many HP it would make as a 2wheel drive on a dyno etc... or 1/4mile times..

any infos you have will be so happy!

RB20/25 engines are all T3 flange turbo's. I have done a twin turbo T28's on a 25 head before and its not worth the time and money involved unless thats something specific you really want. Just spend that money on a bolt on upgrade and you will be happy.

R32 = RB20

R33 = RB25

as mentioned, stock turbo is of a T3 flange.

in reality it is about the same specs as a T28 of and S14/S14 200sx.

GTRGeoff is the user on here who has/had a twin turbo RB25.

I believe he used the Stock GTR turbo's (which are of a T28 nature)

Ask him for his experiences.

if you must have twin turbo, just buy an RB26 instead.

you get a better motor to start with too.
