does the ihi turbo have a gasket where the elbow bolts to the turbo hot side? and if so where do I get one. also I need one for the front where the inlet bolts up too.

I had a gasket on mine when I just took mine apart???? 1988 turbo coupe,,, it also had a gasket on the exhaust manifold, where I heard it doesn't have one from the factory... I will use an exhaust manifold gasket but I don't know if I will use a gasket on the elbow.... I bought some gasket making material since no one carried this gasket around my house

During my recent turbo rebuild I purchased a gasket kit listed on eBay for the RHB5 IHI turbocharger for around $15, IIRC (If I recall correctly). It included two paper-ish gaskets for the aluminum air intake elbow (presumably one for IHI and one for T3), and a rectangular thin metal gasket for the exhaust manifold to turbo flange junction. That’s the one you need for that.

A far more important gasket is the replacement for the Oil Return Line, which the kit also included 2 different ones (Likely for the same reason). Carefully inspect the existing one: DON’T SKIMP ON THIS GASKET. I installed the original one thinking it would work, and I had a nasty oil leak because of it. The good thing is that it’s possible—but difficult—to replace this one, working from above the turbo.

As for the “gasket making material”, are you referring to the junction of the exhaust elbow and the rear of the turbine housing, the one Pete said already that you don’t need (and I don’t have one on mine)? Be aware that, depending on your engine’s state of tune and timing settings, that area could see temperatures ABOVE 1000 DEGREES FAHRENHEIT, when iron starts to glow red.

I’m not aware of a lot of gasket material that can withstand that, which is probably why there is no gasket for it.

1987 Turbo Coupe w/T5OD, 8.8 axle, grey smoke; most options. Got it in 1991 with 41K miles: 3 turbos, 2 heater cores, 1 T5OD full rebuild, 5 clutches, 1 head gasket, 2 Teves II ABS units, etc. later....

ok, thanks for the good info . I wondered how hot those exhaust pieces reach in temperature.... I think i'll go w/o a gasket.
