DSM manifold converted to external WG

[jas_r34]

hey guys im nearing the completion of my turbo finally

just had a question....i have a 14b turbo with dsm manifold but the internal gate was not good so i ditched it for a tial 38MM external WG. ive got the flange for it and its got a 3'' extention with exhaust pipe that i want to weld onto the manifold. Question is how would i do this?

- how to cut the thick cast iron manifold?
- should i ditch the exhaust pipe on the flange because its not thick enough to weld onto cast iron?



ill post some pics later today so its more clear....in the meantime thanks for any input

weld an elbow on the dump?? if i understand this correctly...

I haven't even thought about that! That's brilliant! It would be quite easy to cut off the dump pipe on a DSM O2 housing, weld on a pipe/flange to go to the waste gate and remove the flapper and port out the waste gate port on the exhaust housing.

Although if you do it this route you won't be able to go back to being internally gated, but then if your dump pipe leads to a different waste gate it doubt anyone would be going back anyway.

I'M SO DOING THIS!

haha exactly. Trust me youlle never want internal again. Expecially if you run 15+ psi

yea that idea was option #2.

Id rather try to weld the flange onto the actual manifold tho but if not ill have to go the other route

You could do what I did.

Get one of the aftermarket o2 housings with atmospheric dump. Take off the atmospheric dump, remove the internals of the internal wg, bore out the area where the ig originally was, and get the external wg welded on.

I love mine now.

HEY, can you put up a quick picture? I'd love to see how it looks.
