366 = S300 with 66mm inducer, etc etc etc
SXE or FMW units follow same, although specifically there was only the 362FMW although BW did make a handful of 364FMW's
FMW used a slightly smaller compressor housing than the regular S300's, SXE's use a slightly larger housing than the regular S300's although this larger housing is supposed to be more efficient.
SXE's and FMW's have billet wheel compressors and better bearing systems than the regular S300's
The billet wheels they use are essentially ( and in some cases exactly the same ) as those in the EFR range. They are not just copies of the regular cast 300's wheels of same inducer number.

Now for the cam...solid or hydraulic? I am leaning towards solid but I'm not sure what all is needed to make the 317 heads work with solid lifters. Anyone on here know a good cam guy?

LilJohn above is popular for camshafts.
Or Brian at BTR, Kip at Cam Motion, Martin....ex Tick, not sure what he trades as now.
I'd doubt anything is needed to for the heads to work with solid lifters as the heads have little to do with it ?
Really personal preference as to solid vs hydraulic. There is no doubt hydraulic will work for 98% of applications.
I opted for a low lash solid roller from Kip....but just a personal choice for me. Probably no real performance reason for doing so given both can perform.

Slow progress-
I have the engine sitting in the chassis and now I need to make sure that a pair of s366 or s364's will fit. I have a dry sump and rear mount starter so I am hoping to stuff the turbos in tight against the sides of the block where the starter and oil filter would normally be. The problem is, I can't seem to find a good graphic that shows the external dimensions of these turbos. I would hate to buy a couple just to find that they wont fit anywhere. I have a garrett t04b .70in/1.32 out that I could use to visualize the space but I'm sure the compressor is smaller than the borg.
Does anyone know where I could find the external dimensions? I've googled the hell out of it.

The SXE's are a little larger than the old 366. But it is only a little apparently.
The older 362...and the 364 I have use a smaller housing, but I think the 364 like that was discontinued, but the 362 is still available.
Some pics comparing a GT4094R and a regular 366 and a 364FMW ( same as 362FMW, but not same as the SXE versions which use a larger compressor cover. )
366 has a 0.91 divided T4, the 364 has a 0.88 open scroll.
There is no doubt though that Precision or Turbonetics can build more compact units, although the BW's are fairly short, just larger housings.

I may just have to bite the bullet and order the turbos.
I'll be using LS3 manifolds so would it be better to go with T3 flanges over the T4's?

I see no reason why you'd want a T3 housing anyway

I found the catalog but for some reason they didnt show the outer dimensions for the 366sxe. They did show the dimensions of the s300 sx3. I'll assume these are similar enough in size for my purpose.

Ordering turbos today, S366 or S364??? I'm about to place the order for some Borg s300's but I want to hear from you guys first.
I am leaning towards the s366 since I will be doing mostly standing mile and salt flat runs. I think that I have enough displacement to get me out of the turns anyway.
Any thoughts or suggestions?

Anyone else heard the SXE's aren't making power like they should? I've been told a pair of cast S366's are out performing the SXE line and the Billet S366's from FI really stomp on them. Something to do with the SXE being designed to run at higher pressure ratio's and restrictive compressor housings.

I did see one person mention on a thread here they didnt perform for him.
Although I'm near sure I seen someone either here or YB post about a pair on a 427 doing wonderful things.
BW have been around for a long time, I'd be amazed if their units did not perform. Although of course any units do need selected to work for each application.

Again that would depend on the LS application.
I'd be surprised they are popular on a smaller engine unless it was a drag only application or something. As I really doubt they'd spool very well, and most people running decent boost I know would all use BB turbos, not oil journals.
That said there is a good price difference.
How fast are they going on smaller engines, single turbo applications etc ?

You can make 1300+ wheel horsepower with just a pair of S366's with a 73mm turbine and the .88 Open T4 housing. Genuine borg units with warranty 699 each and in stock.
