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.

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
