The Shadow: Ancient History

by on Jan.01, 1998, under Shadow

About a year and a half after I bought the car, I got into a front-end collision which put the car out of commission for a while.  The front body and chassis was smashed up pretty bad and the radiator and condenser coil was trashed.  Here is a picture after the accident:

The following summer I replaced the bumper beam and struts, hood, left fender, and front grill and repainted them all with original-color paint and clearcoat.  I managed to straighten out the chassis fairly well using my sister’s Shadow as a reference.  We have a neat hydraulic set that’s great for pushing panels and supports out.  The car looks great now, though I wish the paint matched better.  The original paint is not as “orange” as it should be (it has the same paint code as my sister’s Shadow, but doesn’t really match) and the rear, right panel and door don’t match at all (they look almost purple) because the car was obviously in a rear-end collision before I owned it.  But, it’s not all that noticeable.  I had to replace the tires (the primary reason I got into the accident–it still had the original Gatorbacks on it!), but I couldn’t afford a new set of 205/55 VR15s, so I picked up some five spoke rims at a boneyard and put regular 195/75 R14s on it.  I will buy good tires and put the original rims back on when these need to be replaced.  Here is a picture of the car as of the summer of 1998:


I recently (summer of 1998) re-replaced the headgasket, rebuilt the head, and cleaned up the mess I had after an oil line blew under the hood one day.  I also replaced everything in the air conditioning system, put on a new power steering pump, water pump, belts, cap, rotor, wires, and plugs.  I also repainted the intake manifold, throttle body, and valve cover to make it look like a Turbo II (which it eventually will be).

I had also installed a mechanical oil pressure gauge into the dash (the reason for the above mentioned oil mess) along with a remote entry system that I made out of an old car alarm.  In the tunes department, the car has an Alpine 2575 head unit with a 6 disk changer, a line-level equalizer, Polk 5 1/4 speakers up front and 5x7s in the rear powered by a small 50 Watt amp through an electronic crossover, all backed up by a JBL 8 inch subwoofer tube in the hatch powered by Pioneer 160 Watt bridged amp.  This combination, though a bit odd, makes for a very full sounding system.  Here is shot of the dash:

After getting my 1987 Shelby CSX, I decided to go with a different intercooler setup on it.  That gave me the opportunity to install the stock Turbo II intercooler, radiator, and airbox into the Shadow:

It took some time to sort out the plumbing.  The early Turbo II airbox had no accommodations for a BOV or cruise control vacuum supplement vent.  I picked up a Bosch BOV from a SAAB 9000 at a boneyard and installed a hose connection on the curved pipe section of the upper intercooler hose.  See my Blow-Off Valves page for more details on this.  I installed two nipples on the front of the air box, one for the vent, and one for the output of the BOV (the BOV was VERY loud when left open).  This setup works great and I can’t hear the BOV at all.

I then had an ’89 Turbo II SMEC modified by ND Performance for 14.3psi and the usual aggressive fuel delivery and spark curves.  The car smokes the tires in second gear with no problem now and the advanced spark makes a big difference at the bottom end.  When the high boost kicks in at 2800 RPM, my stock Turbo I clutch will occasionally slip.  Next mod will be a Centerforce II clutch.  Right now, I am pretty happy with the Shadow’s setup.  I added an A/F gauge so I can keep an eye on things.  The stock fuel system keeps up with 14.3psi of boost just fine.  Hopefully I’ll be able to make some runs with the G-Tech sometime soon.

One problem with the ND unit is that it can’t control my stock 1988 Turbo 1 turbocharger.  It is the small Mitsubishi TD04 unit and it responds too fast for the SMEC to keep up.  The result was a lot of surging and boost hunting at part throttle.  I resolved this by installing a two-stage bleed with the overboost eliminator.  The first stage is set to about 8psi and the second to 12psi for now (to save my clutch).  The second stage is activated by a WOT switch that I attached to my throttle body.
