Hey im looking for this turbo to be shipped to the southeastern US within the next week. Will pay up to 1500 depending on milage/condition. Anyone have one or know where I can get a slightly used or new turbo at this price?

You'll probably have to settle for a used GT3037S turbo. Brand new, I think they retail for around $1800. I think they usually require a custom manifold too.

What size engine are you putting this on? An RB20 maybe? The largest motor I've seen a GT3037S on is 2.4L(Honda K24). Folks with 4-bangers love 'em. They're supposed to be very responsive, and still good for big power. The weakest motor I've seen with one was a 4G63 in an Evo VI making 450hp, and the highest was an Evo VII that had 540hp.

Have an rb25det in my '95 240sx. The stock turbo was leaking oil and had major shaft play, so I figured i might as well get a better one if im gonna have to fork over the money.

There might be better, cheaper options out there for you if you're using an RB25. Can you find a remanufactured turbo or something? I'm sure there's something cheaper than $1800 for a turbo and then having to get another manifold.

Another issue is the sizing. I was a little surprised to see Top Fuel use a 3037S on a 2.4L Honda K24. I thought they were pretty much for 2L engines, and that was it. Something as big as an RB25 might be pushing it. I might be wrong, but it's just another thing to look into.

how many liter is the RB25 if nissan holds true to other style cars like the VQ30 being 3.0 liter and the VQ35 being a 3.5 liter i would think the RB25 is a 2.5 liter 6 but i and probably wrong

yes the RB25 is 2.5 liter
