To duplicate the stock system BOV method
with twice the flow, healing by adding two stock BOV's instead of one, hospital we know
the stock BOV's work best on these cars but don't provide adequate flow
on high boost like on BPU, price this kit should supply more then enough
releasing flow for BPU, Plus its adjustment free, car wont stall, and
cost less then brand name products with better performance.
: 2 new or
used stock BOV's, 1 Twin Stock BOV's Kit(TSB).
Time Required:
Approximately 30 minutes.
Before you install the 'used' BOV's, Test them!

this at your own risk. we don't guarantee anything.
Make sure you know exactly what you are doing*

This what you get in the kit:
2 copper adaptors(heart of the kit), 1/4 hose, 3/4 hose,
6 1/4 clamps,12 3/4 clamps, 1 T, 4 2X3/4 hoses.

Slip on the 4 pre-cut rubber
hoses to each side of the bov's,
make sure they are oil free.

Slip on the 8 3/4 clamps, get
the clamps face evenly,
dont tighten them up yet

Slip on the two copper
adaptors, notice how the adaptors are
installed, the adaptor with the Angle(left) get installed closer to the BOV
vacuum nipple, the Flat adaptor(right) goes on the opposite side of the vacuum
nipple of the BOV. Tighten All 8 clamps.

Next, get the 1/4 hose, you
will need to cut it in 3 parts,
'approximately' 4, 6 & 24 inches, next join the hoses to the T
that is supplied in the kit, join the hoses as in bottom photo,
make sure to put the 1/4 clamps on each end on the hoses, 6 clamps

Next, get the 3/4 hose and
cut it 'approximately' 15 inches,
slip two 3/4 clamps on the hose and install it to the right side of the
kit(flat pipe),
see photo at the bottom.

Same idea here, get the 3/4
hose and cut it 'approximately' 35 inches,
slip two 3/4 clamps on the hose and install it to the left side of the
kit(angled pipe),
see photo at the bottom.

Insert the kit between the

While your inserting the kit
in place, route the front short 3/4 hose under the large intake hose, then
route it to the boost side of the turbo pipes, and clamp it.

Boost side of the turbo pipes

You will have two hoses
left(the rear hoses),
route the 3/4 hose to the intake side of the turbo pipes(look at pic) and
clamp it,
route the 1/4 hose to the vacuum source of the stock BOV and clamp it.
