Well... got the T3/T4 on Sat... it's beautiful and in very good condition. However, the housings are pointing in the wrong direction and the turbine won't clock (rotate). Any advice would be greatly appreciated. This is a Turbonetics turbo with an add-on internal wastegate.

Yep... of course. I'm taking it by a place today to have them unseal it and clock it for me. I spoke with ATP Turbo (turbonetics was busy) and they told me after running turbos for a while the turbine side will seal really well and need to be broken loose.... working on that now.

My buddy's turbo would NOT turn when we tried..I think it was just sealed shut from being so hot like you said. Hope they get it.

Ok... so does anyone have a sentra SR or honda turbo kit they are building up? If so... I now have one perfect turbo for you. This thing is such a nice turbo... unless you happen to have an RB. There is no shaft play polished housing etc, but that housing won't clock. I spoke with ATP Turbo a bit (very helpful guys over there) and I've been doing everything right... but she's sealed and not going to re-orient itself. So she's perfect for someone's FWD turbo kit...

Time for turbo number 4... oh well... what can you do

Anyone have a RB25 turbo?

The turbo is fully clocked and looks to be in place... turned out very well. Now I just have to go pick up the oil feed fittings and Hybrid is going to fab up the feed line for me in braided SS (said he would for using my turbo... already made a braided water line for me).

Picked up a Saab 900 sidemount off a buddy of mine... looks to be a little bigger/thicker than our stocker and has vert. inlet and exit, so it should work pretty well for now.

rbsileighty, glad you got the turbo clocked. Do you know what fittings fit the oil send and water send lines from the block? I'm thinking they're BPT but correct me if you know. I'd rather not drive to and from homedepot/ace to find out.

Thanks,Daniel

Hey, What do you do for a feed line? I had a -3AN stainless hose I was gonna use, it is fine for the turbo side, but the block uses a metric banjo bolt.

The guy at the local brass fittings place didn't have the proper conversion pieces...
