Hey I drive an S4 with a newly bought S5 hybrid turbo(There was already a S5 stock turbo in there, so it was a direct swap). I noticed when swapping it out today, the hybrid turbo doesn't have a nipple where the intercooler hose connects to for the wastegate. I was wondering if I could just use another vac line from my boost gauge or something and would it work? Also, the intake opening is bigger than stock and I have a S4 stock rubber TID. Anyone know how to make that work? I was thinking just cutting it for now and using a coupler for temporary, but would like a proper way to fix it. If anyone has any ideas, let me know. Thanks.

I think you've got your terms mixed up there, since the intercooler doesn't connect to the wastegate in any way. If you mean there's no nipple on the compressor housing, you can easily add one by drilling and tapping a hole and fitting a brass hose barb. Don't tee off the boost gauge or anything else fed from after the throttle.

Throw it in the bin. It's a huge restriction and if it hasn't cracked yet it soon will. Grab a 3" steel or aluminium bend and some rubber couplers (not plumbing fittings) and make a proper one.

Yeah thanks, I meant the top of the cold side of the turbo. I know it can be easily tapped, but I need a good temp fix so I can get it running to see if everything is in good order first, since I can't weld it on myself. So is tapping the line all right for now, no pushing the car or anything?

And as for the TID, I got a 3 inch all the way replacement, but it has no hole for one of the lines that used to go into the stock TID, it's a small metal nipple that plugs into the stock TID. Can I just cap that off? Or do I need to make a new hole for that too.

Thanks for the help so far.

You should be fine threading in a brass fitting...if you're really worried about any boost leaking out then put some teflon tape on the fitting before you screw it into the compressor housing.

Welding it on is totally unnecessary. The threaded fitting is more than adequate.

It's a PCV line. You can reconnect it if you want or just leave it dangling, but leave the metal check valve in place and don't cap it.

Right on guys, took yall advice on it and stuck in a brass nipple. It looks like it would hold. I have another question though, after flushing my coolant, changing the oil, and swapping in the turbo. I noticed that my oil looks watery. Is there anyway coolant can get into my oil if I just changed the turbo and changed my oil pedestal for my gauges? I mean the turbo lines are pretty straight foward and only go in one way. I'm stumped and don't know if I should try to start the car yet, and what would happen if there was water in my oil? Steam out only, or something bigger? Thanks for the help so far.

more than likely it's gas. did you smell it?

Tmato

Yeah I tried smelling it. It just smells like oil, don't think there's a gas smell to it. But if it was gas, would my car still be ok to run?
