Re: Almost done the the new turbo motor for the rabbit.... (sirhcorrado)
that's a very odd setup
don't think i've ever seen a turbo manifold that put the turbo above the exhaust outlet of the head...
lookin good though... wanna fill us in on a few more detail here???

Its actually just a dual outlet manifold from an early rabbit... theres a full write up about it here. http://forums.vwvortex.com/zerothread?id=249571 don't think i've ever seen a turbo manifold that put the turbo above the exhaust outlet of the head...

you are lucky with the xflow, in my 8v xflow my turbo is right underneat the intake and there is very little room. looking great! what are you doing with that dual turbo outlet?

Looks good. Just a little worried about the injectors. The airshrouded bushings have holes in them for air/vacuum to help the flow, right? If they are at atmosphere, will that mess up the flow at all? I'd be tempted to weld up some sort of thing to screw that bushing into and connect a vacuum line to it so the injectors behave like if they were in a normal airshrouded head.
Anyone else have any thoughts on this? I'm definately no CIS expert.

trashed crossflow - $100
rebuild supplies - $200?
adj. cam gear - $50
dual outlet manifold - $20 (junkyard)
misc. steel for welding - $5 (recycling place)
big T3 - $25 (junkyard)
turbo rebuild - $150
intercooler - $30
audi 5000 WUR - $50
Saab APC system - $50
misc. other crap - ?
As of now I've got a little more than $600 into the whole setup... and I have pretty much all I need (I think). I've got a guy who is gonna weld up my intake for me, shouldn't be more than $100 or so.
Thanks for the input guys, keep it coming!

I was origionally going to use an 8v solid lifter head, but chose the crossflow for its better flow characteristics and intake location. The dual outlet manifold flows into an adapter to the T3 flange... oh boy.

Like most MkI guys, I'm about as cheap as they come. Heres a basic breakdown of the cash involved:trashed crossflow - $100
rebuild supplies - $200?
adj. cam gear - $50
dual outlet manifold - $20 (junkyard)
misc. steel for welding - $5 (recycling place)
big T3 - $25 (junkyard)

Correct me if I'm wrong, on the air shrouded heads there is a passage for air to get the the injectors. Pretty sure its just regular atmospheric air, to help cool the injectors down. Anyone else have any thoughts on this? I'm definately no CIS expert

On my GTI, there is a line going from the air shroud port to, if I remember correctly, one of the emission vacuum lines. One of the lines that runs from the charcoal canister, across the bay to the passenger side.
Anyone else know if the air shroud line is pressurized or just atmospheric?
