which RB series engine

[LaYzIeNoY]

OK well here's the thing im thinking about now, I've been talking about getting my engine swap for a while now and now it has finally come down to it.
I need help in choosing which RB series engine i should choose to do the swap. The 20, 25, or the all powerful all expensive 26 twin turbo.
can anyone help me with information comparing the three as well as a place to purchase them, such as a website or even a place that i can go to I live in florida.

thnx

You actually forgot another good one. The RB30. This is a torque monster.

A lot depends on what you want to achieve, and how deep your pockets are.

RB20's when pushed a bit become very snappy power. In other words if you want to push around 400hp the usuable power is very late in the rev range from about 5,000 rpms or later. It comes on very hard and is very peaky.

RB25's are higher compression engines to start with. They provide decent off boost power. Now they can be pushed very impressive power also. Getting 900hp out of one isn't uncommon. Once you breach the 500hp mark drivability on the street deteriorates rapidly.

RB26's are the god of the RB series. They are also extremely expensive to work on. Anything over 650hp becomes not very nice to drive on the street in 2wd. Power delievery is sudden and the higher the hp the worse it is.

RB30's if set up right can flow huge hp but also suffer from the lack of block strength, especially in the cradle support or nearly lack of. They are a taller block than the other RB series. You can get very nice torque figures even at mild hp figures. For street use they would be ideal for around the same power levels as the RB25 yet due to volume give you the same performance as the RB26 within reason.
