The turbo inlet bolts are rotated a bit clockwise, so it doesn’t line up properly with the redtop piping. You’ll need to modify the T25 inlet, buy a S15 inlet, or get creative by cutting and welding.

You need S14 or S15 oil and coolant lines because the returns are further away.

Did you get a S15 Spec R turbo with the cast divider on the exhaust outlet? Because S15 Spec S turbo is identicle to S14 turbo.

Do yourself a big favour and change the gaskets (Z32). Also make sure you tighten bolts and lock washers correctly. Exhaust leaks are not fun. Enjoy!

Are you using the Nissan OE S15 T28 BB on a non-VVT S13 Blacktop?? If so, you can use the coolant and oil (pressure & return lines as well as the compressor inlet from the S14 VVT Blacktop. I just upgraded to the Garrett GT28RS (“Disco Potato”) and it is also a straight bolt up using the S14 VVT stuff, with the exception of the compressor inlet & outlet. The GT28RS has a round 3" hose inlet and 2" round hose outlet. I’ve got the inlet & outlet off the T28 I’m replacing if that is any help to you?
