Install the throttle body gasket and
then the throttle body.
Note: The stud length, spacer tube
length, and spacer ring height have
been established to work with an
Accel DFI intake manifold and 1-5/8”
tall throttle body. This combination of
parts will place the pressure chamber
at the correct elevation to line up the
turbo boost tubes and provide a
proper seal of the o-rings. If you are
using a different combination of intake
manifold and/or throttle body, you will
need to alter the spacer heights as
necessary to seal the o-rings and
make boost tubes line up. If shortening
the spacer tubes is required, make
sure you remove material from the
non-chamfered end of the tubes.
10.
Slide a pressure chamber spacer
tube over each of the four previously
installed studs so it rests on the
throttle body mounting ear. The
chamfered end of each tube must be
up. Slide a
5 ⁄ 16 " x 1 ⁄ 16 " o-ring over
each stud so it rests in the chamfer on
each tube. See
Figure 27
11.
Set a 5" x 1 ⁄
16
" o-ring onto the
inlet flange surface of the throttle
body. See
Figure 28. Install the
pressure chamber spacer ring onto the
throttle body inlet flange and o-ring.
Note: The spacer ring has a step cut
into one end and a grove in the other.
The end with the step faces down. The
ring may be a tight fit on some throttle
bodies. Set a 5
1 ⁄ 4 " x 1 ⁄ 16 ” o-ring in the
groove on the top edge of the spacer
ring. See
Figure 29.

Apply liquid Teflon to the pipe
threads of a 1 ⁄
4
" x – 4 AN 90° fitting
from the wastegate actuation parts kit.
Install this fitting in the
1 ⁄ 4 " pipe port
on the bottom of the pressure
chamber body near the right front stud
hole. Tighten the fitting so it will point
