Series 2 Alfa 155 Q4
status Future Mods
So what does the future hold for this
Brakes: The current setup of
Fiat Coupe disks/Grale calipers is going to be moved to the rear of
the car to make way for 330mm cross drilled and vented disks gripped
by Alfa 166 3.2 24v calipers.
Suspension: The standard setup
is obviously well past its best by now so over the winter of 07-08 it
is going to be replaced by a full coilover setup.
The original anti-roll bars will be replaced with
uprated sports items, and strut braces will be fitted front and rear.
Also all the bushes will be replaced with poly bushes.
Engine Bottom end: Alongside
the original engine currently in the car, the owner is also in the possesion
of a second engine which is going to be heavily modified. Current plans
for the engine include a full overhaul of the bottom end with uprated
big end bearings and forged conrods. This uprated bottom end will be
spun up by forged pistons.
These uprated components come with
a proven track record as they are used by the supplier in his own Lancia
Delta Integrale which during the summer of 2007 ran the quater mile
(402m) in 9.74sec. This is with an old engine producing only 749hp.
With a new engine on the stand he is hoping to reach 1000hp
Engine Head: The cylinderhead
of the engine will modified to improve gasflow and volume. The main
bolts will also be replaced with larger M12 instead of M10 bolts.
A Spesso headgasket stronger and thicker than standard will be used,
with individual cylinder sealing rings.
Vernier cam timing is going to be used to enable accurate setting up
of the engine timing, but the choice of which cam to use has yet to
be decided upon. The options are pure race cams, modified originals,
original cams, or the cams from the 2.0L n\a engine as fitted to the
Plans for the inlet manifold are either a modified original, Delta Integrale,
or a complete custom manifold.
Larger injectors are of course going to be needed, and their mounting
position will be changed in order to get the most out of them.
A new exhaust manifold is going to be needed to mount up a larger turbo
modified to improve response and power.
To get rid of the exhaust gases as efficiently as possible, a 3.5"
turbo elbow will be sourced or created and mated up to a full 3"
Transmission: The flywheel
is going to be reduced in weight and is going to be mated up to a 4
plate sintered clutch with a sprung centre so it is still relatively
easy to drive on the road. A stronger pressure plate is going to be
used so that the clutch is capable of dealing with the increaded power.
The gearbox is going to get 4mm reinforcing steel plates on either side
to increase overall stength and allow it to survive the increased engine
Bodywork: The front bumper
has already been modified, but over the winter it is due to be remade
in fibreglass instead of the original thick plastic. The rear bumper
is also going to be modified and recreated in fibreglass as well.
The front wings are probably going to be replaced with widebodied wings
to increase clearance as once the coilover suspension and larger brakes
are mounted the standard wings will foul the tyres.
Interior: Inside of the car
as much weight as possible will be saved by replacing all the door panels
with aluminium ones. The carpets will be lifted and all the noise insulation
will be removed then the carpets will be replaced to keep some comfort
for the passengers.
Noise insulation will be removed from the boot to help reduce weight
as well, but as with the cabin, the carpets will be kept.
All the seats are remaining, so the car will still be a 4 seater.
