Borg Warner S363SX-E - N54Tech.com

AZN54 · **Borg Warner S363SX-E -** 06-01-2017, 08:43 AM

Hey guys,

I've decided on going to a top mount single setup and was wondering if anyone has experience with the Borg Warner S363SX-E. It's essentially a 6368; looking at a .91ar. Goal is low-mid 600whp with room to grow. I have a buddy running the S366SX 6673 .91ar and we feel the S363 will be a good option for WHP goal with a quicker spool.

I know the masses are running Precision; great turbos, but looking at something a little different.

Thanks for your input.

I'm running this turbo currently. I chose the 80mm turbine wheel (8780) and .91 a/r. I hit 17 psi (20ish psi target) around 4k.

I will say that the compressor housing is massive and will make for an extremely tight fit.

If I had to do it over again, I think i might have gone with a 64mm GTW. The only way I'll run a precision is if i got it for free.

Thanks for info. I couldnt find a BW 8780 online; do you have a link to it or measurements of the compressor housing? Is it part of their S400 series?

Edit: Disregard, I found it. Thanks again.

yeah its the same as the link you posted. the borg warner nomenclature just goes by different measurements.

Do you guys have any problems with closing the hood on your cars? I'd like to go with this same turbo but I'm afraid of the fitment issues.

Yeah I had to cut a hole in my hood for it to fit. But supposedly the Mani I got was defective. Jerry now says that the manifold has been revised to fit. But idk..

My buddy Nick (italiabari10) with the S366 has the JP manifold and didnt have fitment issues with the hood. I believe he did with the strut tower though. He got his manifold in February 16'.

I haven't had a chance to look into compressor housing measurments between the S366sx and S363sxe yet.

italiabari10 · 06-09-2017, 02:21 PM

Thats correct I did not have any issues with closing my hood. The turbo does sit very close to the strut tower and with the turbo blanket its against it. I drive a 135i and heard the 335i's have better clearance. Jerry said he revised the manifold and considering he is realeasing a BW kit again would tell me he has solved it. With all the negativity surrounding him I would doubt he would want to release a kit with issues. Thats my $.02. **** does happen and its hard to be as percise as a machine. I get people expect things to be perfect but honestly the couple hundred dollars more to make things fit perfect will still be cheaper then other single options and now most twin options.

AZN54 · 06-09-2017, 02:30 PM

Thanks for providing fitment details Nick.

I spoke with AGP Turbo here in Phoenix today and they measured the S366sx and S363sxe compressor housings and said the S363 is about .5 inch larger in diameter than the S366. Hoping this little extra isn't an issue for the strut tower or hood.

The problem wasn't the strut tower for me. My problem was the compressor housing hitting the valve cover and being unable to clock the outlet away from the wastegate as a result.

The compressor housing won't touch the strut tower, only the turbine housing is in that area. The compressor housing will be closest to the hood and valve cover. Nick you aren't as fed up because you didn't have to cut a hole in your hood lol. I wouldn't recommend a s300 sx-e to anyone with a job manifold unless he confirms fitment. Anything else is a crapshoot with that guy.

italiabari10 · 06-09-2017, 04:47 PM

Lol sorry that may have not sounded right. Could you have cut the manifold and have it rewelded instead of cutting the hood? That's what I meant by the extra cost. Also any pictures curious how it looks?

I would have had to pay someone to do that lol. This is my only car and I already can't afford much downtime with needing to go to school and work, so fixing the manifold is not an option lol. I don't have any pics at the moment but I'll put some up maybe tomorrow

Thats what Im running. Good turbo with no fitment issues.

AZN54 · 06-09-2017, 08:46 PM

Unfortunately, it seems a bit difficult to determine fitment with the JP manifold simply due to potential inconsistencies from one to the next. I'm guessing the angle and height at which the turbo flange sits could be off slightly from one to the next. Maybe these small inconsistencies wont make much of difference with such a large compressor housing. I may role the dice on this BW turbo and go from there.

bigdaddyaaron - If you could post or PM me pictures of your fitment and hood, thatd be awesome. Appreciate it!

AZN54 · 06-12-2017, 08:06 AM

I spoke with Jerry over the weekend, he stated he lowered the turbo flange position in order to fit the Borg lineup. I'm going to go with the S363 and see how it fits; will report back. Would still like to see pictures of this turbo mounted if anyone has any.

Thanks guys

Sorry for the delay!
Pictured is the height of the compressor housing. I'd still advise against going with an s300sx-e until Jerry can confirm (with photo) that your hood will close. My housing breaches the surface of the hood by 2+ inches. I used the key for scale.

I doubt the flange could be lowered enough to keep from contacting the hood; Not to mention the structural reinforcement that hangs directly over ("through") the top of the compressor housing. This adds an addition 1.5 to 2 inches. This can be cut, but still.

Wow, you wern't kidding! (not that I didnt believe you before!) No worries on delay; appreciate the pictures. If you don't mind, I'll be sending these to him and making the request you mentioned. If the flange was lowered, would there be enough room to clear the VC or any fitment concern on the bottom side?

If the flange was lowered enough to clear the hood on the current manifold there would basically be no way to fit the front wastegate. It appears to me that only way it would work is with a MAJOR redesign on bank 1's runners and collector positioning.

Theoretically, VC fitment would be even better due to the obtuse angle the compressor housing outlet possesses. The front dump tube may hit the housing instead of the coupler at this point.

Again, I would skip the s300 sx-e line unless you're ok with cutting your hood. The comp housing is just too big.

I run a PTE 5862 which is way smaller "package" wise and my hood hits it with a jp manifold.

Thanks for response. Out of curiosity, how old is the manifold? From a turbo performance standpoint, how do you like the 5862? I believe Terry was running this on his 135i at one point.
