Opinions on DIY mani and how to make it stronger
 

Snaged a new motor today and the previous owner gave me his DIY mani/dp and since the funds are kinda tight i was thinking of just using what i have. Savington brought up a good point about how the OEM header was not made to hold the weight of a turbo, and this DIY mani is clearly made out of parts of the OEM header.

How might i make this thing last a while?

LOL that mani may look like it might flow better than a log mani.

Can you dig up pix of Begi's S4 manifold support?

something like this?

Edit: that flange looks significantly thicker as well

dude... this manifold looks SICK!

you need to weld bracket that goes from turbo inlet flange to a "head" flange. any muffler shop will charge you around $40 to do so.



ps: edited.

This man speaketh the truth.

Another case of "The work computer blues." No pictures available. I would brace it somehow. Mabe someone else has a picture of a braced manifold they can post.

no...The manifold is supported by seven inches of 3/4" Aluminum Rod. :naughty:

That is pretty sweet, brace it and use it. Any pics of the downpipe?

Turbo not hit block?

Manifold looks nice, id brace it for sure though.

Forever to be one of my favorite turbo-related lines.:bowrofl:

I think the brace needs to run from the turbo flange down to the block, or the motor mount. Both dvcn and I have SSAutochrome manifolds braces that way and they're surviving. I'm using some round mild steel rod. It does a nice job of supporting while having some give for expansion/contraction. I originally went with square tube, but it eventually tore. So I sectioning the square and welded up some solid rod in the center.

for a chopped up stock manifold that looks pretty sweet

I just used a bit of 10mm steel rod from the turbo flange to the head flange. The manifold seems pretty similar in design apart from mine being steam pipe, whoever made it had made a pretty good effort I reckon.

Ok, one question...... What is up with the OVERSIZED oil filter sticking out from the valve cover?

yeah, seriously.

Catchcan :giggle:

Came with the motor, its got an oil filter relocation kit on it, and the previous owner had that piece of crap attached to the end of it.

You want the support going to the underside anchored somewhere else other than the head flange for maximum support.

you could also use the factory nuts that are on the mani to bolt 2 upper braces

Here's a bottom mount support courtesy of fredio. It's actually sandwiched between the turbo and mani flange.

what is that black electric thing on the housing

would the fredio plate act as a sort of gasket between the mani and turbo?

curious

would it maybe flex and warp? (doubtful as it is quite thick)

Stock Manifold modified to turbo manifold FTW!!!!

Compressor wheel speed sensor

in theory I'd say it would have too whether it leaked or not just based on the fact that it is located between the two. If it's flat, and both flanges are flat, there's no leaks.

yes... I can't stop thinking about the OE turbo manifestation.:cool:

WRONG, its actually the wastegate solenoid.

Actually, are we talking about the OP's picture, or m2cupcar's picture? I was talking about the black plastic thing on the compressor of THIS photo:

Which IIRC was an OEM's speed sensor. I could still be wrong on this, however.

Attachment 210574
Obviously the black thing hanging off this is the Syclone/Typhoon's #1997152 PWM Solenoid... ;)

I'm talking about m2cupcars picture. I'm right, you are wrong. I'll leave it there.

Rob, if I were a yank I'd be suing you for stealing my foot fetish pics and publicly humiliating me with them ;-)

No, you need something relatively soft to make a gasket. I have two multilayer steel gaskets on that, one on top, one on the bottom.

Yeah you are right, but do you have to be so mean about it? :-p It's the OEM PWM solenoid for boost control on the cummins in the dodge ram it came out of. I hope to one day use it for the same thing on my application :-)

Bracing is crucial IMO, you are going about this the right way! :-)
