This is the wastegate, turbo and exhaust
pipe with the oxygen sensor bung welded in place and the oxygen sensor
installed. I could have purchased a manufactured bung to weld into
the exhaust, but I found that a front spindle nut from an import car had
the same threads and was cheaper. |
|
The oxygen sensor and boost controller are
visible here, as well as the wastegate exhaust pipe. |
|
This is the 3" diameter U-bend I used as
the exhaust pipe. This picture was taken before the oxygen
sensor bung was welded into place and before the boost controller was
added. The Electromotive Tec-II unit can be seen in the upper left
hand side of the picture. |

This shows the exhaust manifold with
wastegate and turbocharger before final positioning. The turbo compressor
outlet had to be rotated down to clear the radiator and exhaust. |
|
After the oil passes through the
turbocharger it needs to be returned to the pan. I dropped the oil pan,
drilled a hole in it and
welded on a pipe thread bung, above the usual level of oil, and threaded
on an AN adapter. -8 stainless hose and fittings are used for the
drain. |
|
Here's another shot of the C-line gated and
baffled 7 quart oil pan with the turbo drain line attached. The
aluminum radius rod in the foreground is a support for the turbocharger
and is shown in the picture below. The radius rod in the background
is the engine mount, it connects to the frame and suspends the engine. |
|
There was no provision for an additional
support for the turbocharger so I cut some 1/8" steel on the band saw to
the shape of the turbo compressor clamp and welded a double-shear mounting
point for the rod-end |
|
I lightly lubed and then slid the injectors
into place and installed the fuel rail from a turbo mustang with a boost
referenced adjustable fuel pressure regulator. Unfortunately, I had
fabbed the intake off of the engine and did not notice that the fuel
pressure regulator interfered with the oil filter. I had to get a
remote filter kit to locate it on the other side of the engine. As a
quick note, before I tried to start the engine, I cranked it over with no
spark to build oil pressure. There was NONE. It seems that the
trusty company who made the remote mount for the filter has mis-labeled
the intake and outlet ports and thanks to the check valve in the filter
itself, no oil would flow. Quickly fixed by swapping oil lines, but ALWAYS
check for oil pressure before starting an engine. |
|
Here's the fuel inlet and return lines at
the fuel rail. I flared the stock hard lines and hooked them to the
braided hose for a leak-free connection and added a fuel pressure gauge. |
|
The aluminum canister is the fuel pressure
regulator and it has a braided line on the bottom that goes to the intake
manifold so the fuel pressure is constant above boost. The braided line
would clearly interfere with an oil filter and you can see the remote
filter adapter and braided lines just below the fuel pressure regulator. |
|
Looking down on the intake the fuel
pressure gauge is visible and just above it in the image is the braided
breather line going from the valve cover to the block and then up and
around to a one-way valve in the exhaust pipe. |
|
This is the throttle body and intake. I had
to make an aluminum arm to connect the red morse throttle cable. |

for the turbo crosses the valve cover. |
