I placed a Sanden SD-7B10 A/C Compressor where you put the alt.  Made similar 1/4" plate mount brackets.  Have yet to make my spacers to align compressor and idler pulleys.  Nice work as usual.

I went with truck spacing accessories and was able to fit a truck alternator AFTER clocking the casing 90* to move the positive post away from the motor mount. I also have a sanden low mount using dirty dingo's low mount and had to notch the motor mount location.

Engine Compartment Modifications-


     I forgot to post the Alternator that I utilized-NAPA #272-4717 104 AMP  Alternator( cost $130).   I originally tried to install a 140AMP GM one but it was way too large to fit in the bottom

driver side of the motor.    I think 104 AMP is sufficient unless I install an Electric Power Steering Unit.   The NAPA Alternator has a Lifetime Warranty and 104 AMP is widely available.




AIr Intake-

    My Crate LS3  6.2 Liter motor did not come with a Air Intake  Setup so I had to fab

one.   Spectre Performance had a 4" Stainless Tube ($75), 36" 0fn 4" Flex Tubing($32)and 4" Right Angle Rubber Elbows(($24) for basis of my system.



I didn't want my Air Inlet to breathe Hot Engine Compartment Air so I fab the system to get Cold Air from just behind the grille.


Had to enlarge the hole in the Core Support to accomplish this.


Also, had to "Tap "  the Wheel Housing to get about 3/4" clearance for the Duct Hose.



Used Shears to Trim the Sheet Metal Plate for the Duct Hose.

   I was planning to post about installing the Holley Terminator X Engine Control Kit but at the

last moment I decided to go to a upgraded version of the Holley Kit.   So that may take a couple of weeks to arrive because of the Pandemic and Christmas.  but there are still plenty work to do.


Drive By Wire Accelerator Pedal Installation-

    Holley recommends  using  AC Delco # 10379038 Pedal  Assembly( Amazon-$88.   However, you have to fabricate your own mount.   Normally, accelerator pedal were easy to fab as they were usually constructed of 3/8"-7/16" steel rod.   One could just heat the rod red hot and bend it as necessary.  However, Electronic Throttle Pedals are constructed of 16 gauge metal and plastic pedal arms.   Thus, fabrication of the pedal mount is a lot more difficult.   Also, the location

of the pedal is in a confined area next to the trans tunnel.

IMG_3569.JPG.d89df544eef31acc20a819c0d55c1edc.JPG   Originally, the pedal would be attached to this plate on the firewall with three screws.


I made paper templates to create the Pedal Mount.

Change  of Plans-


     I must have been a "Good Boy" because my Ungraded Holley Terminator X Max arrived on Christmas Eve.

   Brand New Holley Terminator X Max# 555550-910 was designed for Late Model LS3 motor with 58 CAM, EV6 Injectors, Drive by Wire Throttle Body and a Remote 3.5 Touch Screen Turner was $1540 from Amazon.







   I started by laying the Holley harness over the motor and attaching the sensors.   Everything pretty much lined up but there were wires which were a little

short.  But no big deal.  A little shifting of harness around and  removing the tape on the looms to gain an inch or so. Then,retaping the hareness.   With the harness laid out,  I could tell the major problem would be getting the harness through the firewall to connect to the computer.

    The area between the Battery Tray and Firewall was the only place where everything would fit.  Local Reconstruction Law did not allow relocating the battery into the rear of the car.   Although that location would make harness routing much easier with no battery in the way.   Plus, Weight Distribution would be better too.


This was a small Area for alot of wiring to pass through.   The holes under the battery tray was for the AC Hoses to pass thu.

   I found this Split-Seal Grommets that was big enough but stll provide good sealing qualities.   But they costed $35 each from Amazon.

seal IMG_3711.JPG.1454c88a6f3ecdb0b6ae46c920b59edf.JPG

        Note- The Split-Seal has extra sealing lip at the joint.  It provides a little more joint sealing.

        I also made an additional sheet metal ring to reinforce the seal from the interior

side of the seal.   The Split Seal and Reinforcing Ring was bolted together with six 4MM bolts and nuts.



Cleco Pins were utilized to position the seal while installing.



Engine Compartment View-Seal installed with harness going through the Firewall.



Interior View of Split Seal installed.



Aluminum Templates with various hole sizes were used to determine correct hole to be drilled in the Firewall.  The biggest objects on the harness were the various relays so the hole had to be at least this diameter so the harness could fit thu.



In case you need a custom Grommet , this is the procedure to construct one.



Cut out 23 gauge sheet metal to create the Outer Frame.  Use a razor or knife to make the  Round Seal out of 1/8" rubber sheet.


Finish shaping and use Contact Cement to attach Rubber Seal to frame.  Then drill six Mounting Holes and cut seal in half.  If additional sealing is needed, just make an additional rubber seal on the Interior Side of the seal.


Note-It is important to make the Center Sealing Hole slightly smaller to provide a tight fit with harness.


For Grommets for other Small Wires, you can use Grommets (from Home Depot).

Use the ones made specifically for certain size sheet metal hole.   These seals are usually made of for use in sheel metal holes but check to be sure.


If you want  a tight fit for individual wires, drill slightly larger holes than wire diameter and push wires thu individual holes instead of just slitting the grommets.  This method provides tighter sealing fit.

Battery Box Modifications-

     This is the Delco Replacement Battery for a 2019 Chevrolet Corvette 6.0L LS3.

It is a GelCell Battery rated at 900CCA but weighs 49 pounds.   Because of its weight and size, I decided to beef up the original Battery Tray.



Making a Paper Template of New Battery Tray



I decided to construct the Battery Box out of 16 gauge Stainless Steel.

Used Right Angle Grinder with cutoff wheel to cut the Stainless Steel.




Filing down the sharp edges from cutting.


After Bending the Stainless Steel and tack welding the two

front corners, the Battery Box looked like this.


Front View



Added two Holes on side for Improved Appearance.


Made a Paper Template to locate the Mounting Holes for the

Battery Box.


Template taped the Bottom of the Battery Box to locate holes to be drilled.


  Three 6mm bolt and nuts installed in Firewall to support the Box.



 A 1/8" steel bar was installed in the window cowl to reinforce the three bolts in the firewall.



Four 5/16" Carriage Bolts and nuts secured the Box to existing

Battery Tray.  The Box was polished with Buffing wheel.



Battery Box Version-1

  Sorry for the delay in posting, my PC broke down over the week end and tried to fix it.   But ended up getting a new one at Costco.


Wiring Harness Mounts-

   Since there were so many different sizes harness mounts necessary, I decided to construct my own.   I used 22 gauge 

steel metal with 3/4" to 1" strips.


 Plastic Dip which a Black Plastic Protective Cover used to create no-slip handle covers for hand tools.   Procedure 

is slowly dip the items into the can to add the coatings on.   It works better by dipping multiple times instead trying

to make one heavy coating.   I dipped the mounts in about three to four times( allow 30 minutes drying time between

coats) to get thick but smooth coatings.



Let it dry completely dry  for 24 hours before using.


I used Metric Nut Inserts to hold the harness mounts and found that some locations were too tight to use the normal

Thread Insert Rivet Pliers.   So I constructed a simple tool to do this job in "Real Tight Places.   Used !/8" x 3/4" x 8"

mild steel plate with 1/4" hole drilled in one end.



Just inset a 4MM insert insert in the hole and place the right size bolt on the 4MM insert.  

Then, just tighten the bolt and it will squeeze the nutsert tight.



In REAL TIGHT PLACES, you can use a Hand Wrench instead of a ratchet and socket.  It takes longer but it will work too.


Wiring Harness Looms


Previously I used Flexible Plastic Split Opening Wiring Looms but found out these looms would hold water and debris

in them.    So now, First, Premium Scotch Brand Black Electric Tape was wrapped tightly over the wire harness.  Then

Alex Tech Split Sleeve Wiring Looms were installed over that.   This braided covering is very tear resistant but allow water to drain out.




ALEX TECH SPLIT SLEEVING is sold on Amazon with  !/4", 1/2",3/4" and 1" tubing sizes.

Note-After cutting the ends off, it is recommended that a mini torch be used to burn the 

ends slightly to prevent ends from coming apart.   The ends can be taped with electrical tape or

use Heat Shrink tubing to hold the ends down.   I noticed that even factory wiring comes with this type of looms.


Holley Terminator Computer Installation


The Holley Terminator Computer was installed on the Passenger Side Kick Panel with fabricated mount.  

Note-Wiring harness Mounting Clamp holding the harness it the firewall.


A 1/8" Aluminum Protective Plate was added to bottom area of the computer to prevent damage

to the wiring.



The Computer Maintenance LED Lights are located on the top of the computer so are still visible in this location.   The computer mount was built with 1" clearance for the wiring to allow wiring to go underneath.


The Holley 3 1/2" LED Touch Screen Display was stored in the Glove Compartment.  It will be used to tune the computer.




 Holley Universal Oil Pressure Transducer 

     The Factory LS3 Oil Pressure Sender will not function with the Holley Computer so  the

Holley Oil Pressure Transducer must be utilized.   Cost $140 from Amazon.



Holley Included the Oxygen Sensor Bung that must be welded in the Front Exhaust pipe after the

exhaust manifold.




Horn installation-

Speedometer Modifications-


     There are Three Options to get a working Speedometer with LS Swap 240Z.   First ,  Keep the Original Z speedometer and convert  your T56 trans to Manual Speedometer.  This option requires sending the trans rear extension housing to be machined to handle "old type" plastic speedometer gearing.  There is a place in Washinton State that does this work for about $400 and you have to ship it to them.  Second option is to replacinging the original Z Speedometer Unit with a new GPS Speedometer.   This method may require modifying the dashboard to install because of size differences.  Also, GPS would not function in tunnels.  Cost about $300. The Third option is utilizing an Electronic Speedometer to Manual Speedometer Conversion Kit.   These kits convert the  VSS ( Vehicle Speed Sensor) signal to an electronic motor in a control box.  A cable from this box drives a cable to Z Speedometer.   Advantages of these kits are One Day Installation Time and Easy Recalibration when changing tire sizes and rear differential gearing.  Cost about $329.    I chose the Dakota Digital ECD-200BT-1.   This model has a GM (old style) threaded collar speedometer cable.


 IMG_4001.JPG.acd843cb86084370d934a87eeee08381.JPG   Note-Different cable versions




  Although the GM Threaded Cable is very similar to the Datsun Z cable, it does not screw on but it is very close,though).

So you must perform a little fab work to make it fit.   First, I measure the cable measurements of the 240z cable.




The Most important measurement is the speedometer stick out from the housing.   Now, you cut the 240z threaded sleeve off with a Dremel with Cutoff Saw Blade.



I used a piece of 1/4" thin tubing (about 2" off of a Acid Brush Handle)  and Silver Soldered to

240z cable cup section.   Silver Solder melts at 300 degrees but provides a very strong weld.

This modified section was then slipped over the Dakota Digital  cable after removing its  section

with the Dermel too.   Then the modified section attached to the Dakota Cable with JB Weld.  Set the cable stick out to the previous  measurement.   Remember to allow the JB weld to cure 24 hours before using.



240z Cable Threaded Sleeve installed on Dakota Digital cable with minor surgery.


The Dakota Digital cable was tested with a Cordless Drill running in Reverse Direction.



Note-Speedometer Needle moving at speed.


The Cable Drive Unit was attached to under the Glove Compartment.

FYI, a 4th speedometer option is to find a GM speedo that will 'fit' inside the Z housing and mount it in there that way.  Takes a little bit of time to make it look right, and probably some junkyard searching, but I did that with my Ford swap and it's worked perfect for 10+yrs. 


I considered suggesting mounting the OEM stepper motor inside the Z housing, but then you need the electronics from the GM gauge cluster somewhere and hope the sweep angle is the same between the GM and Datsun gauge (not likely).

240Z Power Steering Installation-


      As I planned to have wide wheels and tires, power steering is almost a necessity in tight driving areas.   There are  BMW 318 hydraulic racks have successively installed in 240Zs.  These racks are difficult to find and require different outer tie rod ends.   Also, mounts for 

the conversion racks must be modified.  There are two Electric Power Steering kits available for 240zs-Z Power Steering and Silvermine Motorsports.   Z Power Steering requires you to send them your steering column to modify.  Cost about $800 + Freight.   Silvermine Motorsports Powering Steering is ready to install but costs $1250 + Freight.   Considering 

all the factors. I chose the Silvermine Power Steering Unit.

 Plug in Connectors for Control Box


Installation of the Steering Column takes normally  about 2 to 3 hours.   I decided to modify the  Brake/ Clutch PedalMounting Bracket to allow the Motor to move a total of 180 degrees for additional leg clearance.   Also, Offsetting the Steering Column Firewall Mount created additional e steering shaft to motor clearance.


Made a Template for modifying the Steering Shaft Mount on the Firewall.





Note- The Hole for the Steering Shaft Mount Plate is not round.  It is actually an "Oval" similar shape.   When a Round Tube passes through a Flat Plane at an Angle, it creates an Oval Hole.

If you just drill a Round Hole, there would be large gaps around the edges that would need to be filled in.

I ended up leaving the Power Steering Motor in the Right Side of the Column.  This position would

provide the most clearance for both my leg( left and right) movements.

Detailed Measurements-


 With the Motor on Right Side of the Column, Distance between motor and floor is 14 1/4"



With the Motor on Left Side of the Column, Distance between Motor and Floor is 14 1/2"




Distance between exhaust manifold and steering shaft is 1/2".




Distance between Firewall and Bolt in Steering Shaft Adaptor is 6".

  • 1 month later...



    Because of limited engine compartment space, I decided to build a Fuse/ Relay and Battery Junction Panel in the

Passenger Side of the Transmission Tunnel.    

   The Panel was made from 1/4" Black Sheet Plastic.   The Dimensions were about  7" x  10 1/2".   The  Legs were made to provide 1" space underneath to run wiring .  The Plastic was bent by using a straight edge and 1000 Watt Heat Gun.



The  Basic Layout Plan for the Panel.   This Diagram show wiring for Speedometer Convertor and Electric Power Steering.



I use  Four 80/ 60 Amp Relays as the relays will be powering more than one circuit at a time.



This 4 Pin 80/60 Amp 12vt DC Waterproof Relay comes with 12 AWG insulated wires.

Costs $38 for Four Relays from Amazon



This pic show a 40 amp In Line Fuse Waterproof Housing with 10 Gauge wire.   This In Line Fuse will used as the Terminal Fuse Block was rated at only 30 amps.   This  Fuse was utilized for the Electric Power Steering Motor.




This Dual Rows Block Terminal Strip from Amazon costs $8 for two.



This 6 Way Fuse with 5 Fused Circuits with seperayte Postive anf Negative Bus Bars costs

$17 from Amazon.



The top 12gauge Red Wire has a inline waterproof 40 AMP Fuse.   This Fuse protects the 

Electric Power Steering Motor.    I could not use the Fuse Block as it was rated at only 30AMPs.



 The White Relay wires trigger powers the Blue12vt wires that connected to the Positive  Bus Bar.

Then the 12volts exit the Relay through the Red Wires.  Then the 12vt crosses the conection to 

the Output wires.   The Vertical Fuses protected each circuit.   The Black wires on the Right Side

connect to Negative bus bar(Ground).   The Top 1/4" threaded stud connects to Battery Positive

terminal.   The Lower 1/4" threaded stud connects to a Negative Ground strap.


The Panel with the wires all connected.   Note- Wires when possible are run under the panel to

provide a clean appearance.   Majority of the Output Wires were required Key On Operation.   Some 

Devices like the Holley Terminator Computer,  Silver Mine Power Steering required straight Battery

Power but still ran thru a Fused circuit.



The Relay Panel was mounted to Transmission Tunnel with battery cables attached.



A Marine 12vt Battery Cable holds cables from the  Relay Panel,Alternator and Starter Motor.



The Negative Cable attaches with a Post Master Quik Disconnect Switch.   It can be disconnected with just a twist of the Black Knob.   Costs $14 from Amazon



More Wiring to come.

mutantZ,   No, the lower section of the steering column is not made of plastic.   Both factory and Silvermine columns are constructed with metal components.   All modern steering columns consists of both collapsible exterior housing and steering shafts.   The methods to accomplish this task may differ but the end result is the same. Collapsible steering

parts must be replaced if damaged to provide same degree of protection.  Even when working on these components,

care must be used not to damage them (excessive force like hammering,etc).

Sorry for the delayed posting, I had to do some house repairs.


       More Wiring to do.

Starter Solenoid-

    My AC Delco Starter#1266257 was one of those Mitsubishi Gear Reduction ones and I was having a difficult time finding the correct Solenoid Wire for it.   I ordered three different Solenoid Wires for it and all of them didn't fit.

I finally found the correct one on Ebay.   It was specifically for 2019-22 Camaro with a LS3 6.0L.   It costs $59.00 but at least it fits.   The Solenoid Lead Wire is fully insulated too.




Pic of Starter and Solenoid

Fuel Pump Relay- 

     As my Holley In The Tank Fuel Pump is far away from the battery, I decided to to run a Dedicated  Fuel Pump Relay. It is rated at 60-80 AMPS.   I already ran a 12 Gauge Wire from the battery to the Relay in the harness.  The Factory Electric Pump "Green" Wire was used to trigger to relay which will then send Full Battery Voltage to the Pump.  So If I decided to upgrade

the Fuel Pump to a bigger one,  eveyrthing is done already.


Rear Tail Lights Repair-

    Upon inspecting the Rear Tail Lights(Left and Right Sides) , I found corrosion on Sockets and Ground Wires on the

sockets and related wiring. 

IMG_4100.JPG.8b8eba01a90d3542fc11424db399672e.JPG Disassembly of the Lamp Sockets

 so I decided to repair the ones that need repair or replacement.   Amazon has Socket Repair Kits which contain the

necessary parts and wire leads.   Make to get the correct dimensions for the socket and type of sockets( two wire, one wire, two contacts one contacts, straight ears or offset ears.  If the new sockets are loose in the plastic holder, you put some Hot Glue on the sockets to make them fit tight.


 Original Factory on Left and Replacement on Right



The Single Contact Lamp Socket replacement


To be used, the flat bracket must be cut off.


Before connecting the Lamp Sockets to the harness, all of the Lamps were tested.



Note- I went to LED Bulbs for the whole car. not just the Rear Lights.   Led Lights will also lower the Amerage draw compared to the original Incandescent Bulbs.  I found some White Turn Signal Connectors discolored Brown because of Overheating.

Dome Light Repair-

    The Original Dome Light Assembly was found to be defective when I tested it before installation.

IMG_4159.JPG.01888b70b01e3e297d734872c2ae1b65.JPG The problem was the Light Switch was not functioning.


I found a 12vt Micro On/ Off Switch on Amazon for $12 for six switches.



The defective switch  was removed and prepared for new one.

Transmission Floor Shifter Boot Cover-

    The Transmission Shifter Boot Cover will actually consists of two covers -Rubber and Leather

ones.   The Rubber One will stop Heat and Hot Air from entering the interior.   The Leather One is'

more of decorative reason.

   The Shifter Mounting Plate was constructed of 22 Gauge sheetmetal.




Test Fitting of Shifter Mounting Plate



Reverse Lockout Solenoid Switch-

    I decided to keep the Reverse Lockout Solenoid but simplify its operation.   A  Momentary On/Off

Switch would be mounted rignt behind the Shifter.   It would be located a {olished Aluminum plate

on the Center Console.   Operation is simple-when you want to shift into Reverse Gear, Your Left

Hand will press down on the Reverse Lockout Momentary Switch( activating / openin the Lockout

Gate.   The Right Hand will shift the Shifter Lever to the Right Direction and Up into Reverse Gear.

Note-Extra Room on Aluminum Console Plate for Future Switches( Fog Lights, Nitrous,etc)


Problem with Precision Door Weatherstripping-

     Some other Z members also had problems with Precision Door Weatherstripping.   The  Precision Door Weatherstripping was made of Thick and Hard Rubber materials.   When it comes across Tight Fitting Contact areas, it does not compress enough.   Thus, you had to slam the doors

until the weatherstripping compresses.   Later model car weather stripping are made of very soft and large air pockets for compressibility.

    I found that major problem was at the top of the door edge meets the rear quarter glass.

The Weatherstripping is squeezed into very tight area but can not compress enough to function properly.   So you can replace the weatherstripping with a much softer material or increase the 

door gap.   Since my door panels were worn and I was thinking of constructing the door panels

out of 22 gauge Aluminum sheet, I tried to do some metal working on the panel.  Taking off the 

interior covering of the upper rear corner of the panel, it was constructed a steel metal.


Upper top corner of Drivers Door



So if I could "flatten" this area, it might give enough room for the weatherstripping to fit.

The Large Hump would have to be "slit' in couple places to allow the flattening process.


A Dremel with Cut Off Wheel cut the slits.




Cut another Slit on the bottom edge.



Pound the area "flat" with  Hammer with panel on a flat hard table.



A third Slit allows more flattening.



The over lapping slits were tack welded.


1645032235_IMG_4318(1).JPG.77ea333aa560e3170e6e0b5b21ef2675.JPG  On the Door Side, I replaced the Door Glass

Vertical Upper Mounting Bolt(6mm) with a Counter Sink Phillips To gain even more space.



Note-Flattening allowed the door to shut now.

Led Flasher-

    I think I forgot to mention that if you are replacing the vehicle's incandescent light bulbs with LED Bulbs, you must use a LED Flasher.   If you don't. the turn signal and hazard lights will not blink and will stay solid.   This is because the LED bulbs will not draw sufficient amperage to cause the Flasher to heat up and blink.   I got mine from Amazon for about $12.   The Led Flasher came with an external ground lead too.




Front Fiberglass Bumper-

    The Greddy Fiberglass Bumper that came with the Rocket Bunny Body Kit has just been laying on the bumper waiting for the finishing touches.


       Bumper reinforcement frame built from with 1" square steel tubing.




The Fiberglass was first aligned with the front body panels.   Locitite Tile Foam was used temporarily to hold the

bumper in alignment so I could fill it with Pour Foam.   But the bumper with reinforcement had to be placed in a level

and vertical position with the front of bumper facing downward.   


Shooting the Foam to just hold the Bumper and reinforcement in alignment.


Pic of the Tite Foam after expansion, it was trimmed down.



Now. the Bumper was ready for the Pour Foam purchased from the local Marine Supply Store for $30).

This Polyurethane Foam will fit the space between the reinforcement bar and the bumper.  This will create a solid bumper instead of just a hollow fiberglass shell.



To use, mix equal parts( one to one ratio)  but you have only a very short time before the mixture will expand-only minutes.  The foam will expand to 5 or more times the original amount.   I would suggest that you mix only one spoon full to see how much

the  Pour Foam does expand for the first time.   I made several pours instead of doing a single pour.  Once the Pour Foam fully expands, you can still immediately make the next pour.   I used a old hacksaw blade to trim the expanded Foam as it works better than a knife or razor blade.

After triming and sanding the Foam to 3/4" from the edge of the bumper, I poured  Finishing

Figerglass Resin over everthing inside on the bumper.   This will seal everthing up so water can not

enter. This process  also will strengthen the bumper although it will create addition weight.  Then exterior of the bumper was painted with Gloss Black Polyurethane Paint then buffed.

Made two Wooden Stands to hold the Bumper in proper position for putting the Pour Foam into

the Bumper Cavity.

Wilwood 1" Master Cylinder Installation-

    The Factory Master Cylinder had a 7/8" bore and Wilwood 1" Master has a 1" bore.  Its

front reservoir is behind the rear reservoir so  I fabricated new Master output lines.   I used Napa

Bendable 3/16" brake lines because the lines had to be bent in a "U" shape to go under the Brake

Proportioning Valve.  It is made of Nickel and Copper Steel .   Also, the Wilwood Master output

lines are SAE 3/8NF so I used NAPA Bendable  3/16" lines with 10mm brake nuts.  Then, I cut off one end of the line and remove the Metric Line Nut and replaced it 3/8NF Brake Line Nut.   Then Double Flare that end.   Now, you have a Brake Line with Metric Brake Line Nuts for the Proportioning Valve side and SAE 3/8"NF on the Master cylinder side.


Note-Nickel and Copper Lines different color


While I was working there, I decided to construct a Heat Shield for the Brake Lines.

As usual. I made a Paper Template for the Heat Shield.


It was constructed out of 20 gauge Aluminum sheet.


Made a Trial Model of Key Hole Bolt Hole

Finished  Shield.  Note-A simple "KEY Hole" mount  design was used.   Loosening the Proportioning Valve Mounting Bolt and moving it outward slightly.  Align the mounting Bolt with Round Section of the Key Hole. Then slide the Shield downward over the bolt.  Tighten the bolt.   A Simple Method but effective for tight spaces.
