There is no RB25DETT
THe RB motors of any interst are as follows
RB20DET = 2 liter single turbo ( I have one of these in my car)
RB25DET = 2.5 liter single turbo
RB26DETT = 2.6 liter twin turbo (from Skyline GT-R's and Stagea RS260)
RB30Et = 3liter single turbo single cam. Often converted to twin cam with an RB26 head installed ... can make HUGE hp #'s with stock internals.
I assume you are talking about putting one in a 240sx...
The RB20 can be installed and modded a good bit for the price on just buying the SR uninstalled. The RB is faster in stock form and costs half as much. Oh, and is easier to wire to the 240.
The SR is a waste of money in my opinion, because for the $2500 to $3000 it costs to buy one (with 215hp) you can buid a KA24DE with forged rods and pistons. Install larger injectors and an SAFC, Emanage, or ECU tune and bolt on a T3/T4 and make 450-500hp AT THE WHEELS!!!
To get an SR to that power would take another $3000-$5000 in addition to the $3000 you paid for it, to get those #'s
