    You sure can, but one of them will not be cheap. I guess what I am saying is the borg sxe turbo's are great cheap turbo's, but I don't think they are going to fit on the cheaper manifold options such as the spa or rapidspool. I could be wrong on that, somebody will have to try

    I gotcha. I'm super impressed with this 366sxe, it's a beast of a turbo. Even spooling stupid fast for what it is on an open mani. I'm seeing ~18psi by 4k and in 4th, that's with a mbc and a 12# wg spring.

    I'm almost positive it will not fit on a spa. People have tried, and it doesn't work.

    How does the S300 compare to the GT40r in comp housing size?

    as my GT40 did NOT fit with SPA T4

    Everything I have heard is that the s3xx has a bigger compressor cover than a 40r.

    This is my 366sxe next to my old 256. Pretty good visualization of how massive it is.

    Here you can see the 366sxe snugly sitting a mm or so from the block.

    I used to have a GT4088 and my S366 was a good deal bigger.

    All of this has me thinking: If you were going to spend money either for a tubular exhaust manifold (or perhaps the CES) with a twin scroll turbine OR an EFR 8374 with an open T3 turbine, which would it be? I have no direct experience with comparing a twin scroll to an open style turbine so I'm not sure how much it should concern me.
