gt35/40 installation
 

I fabricated a downpipe with mild steel elbows and a flex joint. I hope it lasts since it's my first hack at welding.

Here is a pic of the old downpipe (previous owner), my downpipe, and HKS manifold with T4/T3 adapter flange welded to it.

HKS Manifold after the HKS T3/T4 adapter was welded on the original T4 flange.

Yes, I know the welds will disturb the exhaust pulse flow. I need to smoothen the weld out.

Clearance from the frame to the turbo wasn't much, but it's enough.

Fitting the downpipe on the turbine outlet flange.

Fits pretty good with the rest of the exhaust.

Entire mock-up (different from final in a few ways).

You'll notice the J-spec lower intake manifold was used since the EGR cast in the manifold hit the top of the turbine housing.

I switched around the water line fittings.

I will hate removing/installing this set-up again since everything is so hard to access.
