so i have a borg warner s360 and im running a top mount manifold. if you know your turbos, then you know this is one big sucker and is not on the light side when it comes to weight(the turbo). my concern is if i will need to make a supporting bracket for the manifold. and if i do need to, where should it be mounted? on the chassis with a bushing/mount setup? or on the motor?

 

what application? fwd? rwd? motor plate? stock solid mounts? what material is the manifold?

 

fwd, lsv-t, in an ef hatch, aftermkt mounts, manifold material is unknown. no motor plate. i had the idea to use one but heard its annoying as hell to run in a dd car.

 

definitely brace it to the motor itself.

if its schedule 10/40 pipe fabricated by a well known shop, shouldnt needed any additional bracing. all the full-race/neukin/afi/peakboost schedule manifolds have lifetime warranty for a reason.

if its a tube header, a heim joint off the engine will work great.

 

do you have any supporting pictures as to what the completed and mocked bracket should/would look like? i was thinking about mounting it from the oil pan area but im scared over time the threads would get damaged or one of the studs might get pulled out.

 

search heim joints on google.

use the ps or ac bolt threads

 

 

those are just the joints themselves.

 

Hahaha sh!ft. I figured it would only be a bit of time before I saw a post from you in here. The Sch40 will support the weight just fine, when the manifold is built well and correctly you wont have any issues. Especially with a top mount. The amount of "bracing" built into it will be sufficient. Especially since Hypothetically the weight will be sitting on the flange rather than hanging off of it. If you were closer i'd suggest we work out something with me building another one. Honestly, i'd love it give another manifold a try soon. At least until I get the S2k in the shop.

 

sch40?


for the record, this is the mani i am using and NO, its not an obx

 

Who built the manifold? What brand? The manifold it self is a brace. No need to worry if the manifold builder knew what they were doing...

 

Sch40 means "schedule" 40, it refers to the thickness of the pipe. Also......you know you need to run a t4 divided flange with that right? With cylinders 1-3 and 2-4 paired with that S360 correct? Otherwise the divided housing is kaput.

 

Wrong, it doesn't have to be a twin scroll exhaust housing on s360 turbos. In fact, I have a open scroll t4 s360 sitting right in front of me. I pretty sure you can get open scroll t3 housings as well. Just saying

 

who built the manifold? i have no clue, but it has very nice/acceptable welds on it from what i can tell. i just dont want to tear something up that is from what i can tell a quality built manifold.

as far as i knew, the twin scroll was mainly made to help balance the turbo. why would you need 2 flanges to help balance the turbo if it came from the manuf. with a flange on the turbo already? some one must have already did the r&d to make sure this turbo could accept a twin and non twin scroll manifold if its already on the market.

 

Sorry but thats a OBX/ebay manifold.

He has MY turbo.....I mailed it to him last week. It has a divided housing.

 

Pairing for a divided housing turbo is cylinders 1-4/2-3, not 1-3/2-4.

 

I mis-typed sorry, but yes correct. However, point made that he either needs a new housing or a new manifold.

 

well now that i know what i have, i guess it'l have to do till i can get a new one.

 

A divided turbo housing will work just fine on a non divided manifold

 

Yeah, China status as hell.

Polished Schedule tubing with pulsed over slag welds, I think they use some weird flux to force that color too or something.

 

Possibly true but with a turbo this large on such a small engine it will VERY much slow your spool up time and increase "pulses" on the wheel.
