Help: S4 Turbo Oil Return Won't Fit S5 Hybrid Turbo
 

Alright. I've been running a stock s5 turbo on my 88tII (s4). Well, I picked up a used s5 hybrid (by FEED). Well, when getting installed, we found out that the oil return line (s4) won't quite go one because it's hitting the housing of the new turbo. It's really close to fitting but just not quite. What are my options? Is the s5 oil return line any different and be the problem solver or would that be completely different? Also, it looks like it MIGHT be possible to grind down the s4 line now, but I'm just leary of doing that and ruining the line for no reason. Also, if neither of these are the better option. Where could I get a custom line made for this? Thanks guys.

this should help you out.

That may be what I have to do....has anybody else ran into this issue?

I`m still reassembling everything but my S5 BNR stage 2 hybrid installed on my 88 T2
using the S4 lines (both oil and coolant) gave me no problem getting them reconnected. It may be that since only the compressor and its housing are different I didn't run into the same issue as you though.

Completely different. Won't fit.
