Like i said some people say it does some people say it doesnt. If you want to play it safe route it to your intercooler piping, less headaches later on.

Is this unique to the 1.6? I didn't see that pipe on my 1.8.

Yeah I will most likely be routing it back in, I have a feeling I'm going to have a lot of other bugs to work out

Once it's back from exhaust I should have everything I need to get it running. I still have to figure out my clutch issue, it's not building enough pressure it seems (the pedal has very little resistance), throw the rest of the parts at it I've been stockpiling, and hope for the best. I'm trying to get it running for the good weather

Just got off the phone with the exhaust shop, the downpipe is complete, he'll be moving on to the rest of the exhaust tomorrow.

ha! I have no way to mandrel bend pipe, nor do I want to weld a million different pieces together. Better to let the professionals take care of this one.

My 99 has it; I've put a one-way valve and a filter on it.

Exhaust is now complete ! I'm having him do my intercooler piping as well. I should be picking the car up at the end of the week.

I broke my camera, so I'll have to use crappy iphone pics :(.

Turbo to downpipe flange ETD racing recommended putting the EGT probe here on the downpipe vs on the manifold itself as they've had problems with them cracking in the past. The temperature difference between the 2 locations should be negligible:

routed the wastegate dumptube back into the exhaust:

I would have liked a shallower "entry" but space was very limited. The downpipe is 2.5" (couldn't get 3" to clear the TII bellhousing), then it expands to 3" all the way back, all 409 stainless steel. There are very minimal bends, and it's tucked up fairly high for ground clearance. This thing is going to sound mean!

I also had him make my intercooler pipes out of 2.5" mild steel. I'm going to go back and fab up the BOV flange (didn't like how my last one turned out) as well as the IAT bung and the IAC tube.

No room for a radiator fan on the right side eh? Or is that a optical illusion?

Also, I don't know what the delta_T across a turbine is, but I doubt it fit my definition of negligible. But better that then a cracked mani I guess.

Doesnt look like there will be enough space for a second (stock) fan. Some spal low pro fans will probably be fine.

Iphone pictures aren't very bad at all, 3GS? my 3Gs pix are not very good at all.

There's room for a fan if the IC pipe is going behind the sway. Curious to see the bellhousing clearance - or lack of you mention for the down the pipe. I've never heard that being an issue with other TII installs.

There's enough room for a fan. I have a thin 12" spal one already, just haven't got around to building a shroud/mounting system for it. If I need more cooling believe it or not there is room on the pass side for a smaller fan. I'm hoping this will do OK, but there's only 1 way to find out. As for the probe, I thought the same thing, but they said this is what they've been doing on their racecars for years. Again, only 1 way to find out I guess.

When I get the car up I'll take some better pictures of the clearance. The clearance issue for 3" downpipe vs 2.5" also arises from the ETD manifold- it left the turbo and wastegate in an awkward position. The smaller pipe allowed for a more direct path. It expands to 3" right after the bellhousing; the 2.5" section is very short.
