GN1 3.5" downpipe with External Wastegate

[TTipe]

I was thinking about purchasing this downpipe and hoping to get some feedback from someone. What wastegate (Tial, Turbonetics, etc. ) do they include. Do they furnish the spring kit? Is the flange flat? What quality are the welds? This is the kind of info I'm looking for .

Thanks

Integral.... that means it has a puck inside .. just like the stock turbo elbow ... uses your wastegate actuator mounted to the turbo compressor cover just like stock was ...so i dont understand your question

Please excuse me. I mean't an external gate such as a Tial / Turbonetics Delta gate.

Would a moderator please lock this thread. I messed up and this causes confusion. Again my apologies.

the gn1 uses a china gate (cheap on ebay), newer ones have vband flange , older style was a 4bolt flange
the gate is not known for its reliability , i would replace it with a pw46 precision gate that includes full spring assortment
it has one spring (he sells other sizes)
, its welded ok but some have cracked ,
it clears headers but it also swings out wide and requires cutting out the plastic wheelhouse

I was afraid of this. I can't see myself purchasing that. Is there another supplier who fabricates a 3.5" downpipe with provisions for an external gate and Vband flange.

i dont know of anyone offering one . cottons could probably build one (murphster has one of theirs) but it wont be anywhere near as cheap as the gn1

If Jack fabs it up the the thing will work properly

Brian Cotton will build most everything per order these days. Seems like so many people have so many different requests and combinations. I believe making generic configured parts to bolt on stockers is getting more and more difficult.

No doubt. I'll have to call Jack.
