brakes

Time to replace the rotors.  Turns out the brakes are from a 70 to 73 celica/corolla/corona with 9" solid rotors. 

Calipers are Akebono 1 7/8 "1708"

the rotors were in rough shape and at $37 each its easier to replace than have them turned.

And now the new.

Time to replace the burnt out glass pack muffler.

Started by gutting cat, installing heavy mesh insert in cat, replacing glass pack with flowmaster hp2 laminar flow muffler. 

Lots of welding and grinding to make it leak free then wrapping with header wrap.  

 

I like the sound and decibels have dropped by 10 according to the sound meter app.  the tone is a lot deeper too. 

metal boot cover

I was looking at several different soft boot covers.  For the money I did not see anything that I liked and would let me lock the removable steering wheel away and out of site.

A little more fit and finish is needed then some paint and the lock.  

All metal with sliding plates around roll bare brace.  

Lock installed and cleaned.  Need to decide if I will leave the metal raw or paint black.

Under the Hood

   several months and a few adjustments made

 - under hood seal

- removed evap canister and lines that were not connected 

- installed fuel filter

- installed new mechanical fuel pump

    - pump was too high a pressure.  the New old stock pump was suppose to be 4 - 8 PSA.  It was running at 6.8 psi when installed.  

     - installed Mr Gasket 1 - 6 PSI fuel regulator

    - set Fuel Pressure on regulator at 1.5 PSI and it measured 3 at the Carbs with Fuel Pressure guage

MSD Ignition

- unable to set the timing to 12BTDC with timing light.   MSD needs old school static type.  

- separated the plug wires to ensure best chance of setting timing on Cyl 1

- plug wires did not have ends at the Dist.

- installed plug wire ends and re-routed wires for seperation

- set timing with 3122 timing light. to 12 BTDC

Carb Setup

- Adjusting the air horns changed the fuel needs.  Mikuni PHH44 were overly rich and fouling plugs

- changed plugs to iridium.

- Overly rich and poor milage 

- turned down fuel at Pilot jet screw.  from 3 or 2 turns 

- installed innovate MTX-L AFR Guage

    -  AFT at 10 or less at idle, Cruze AFR 10.5 and transition 11.2 and WOT 10.2

    - turn down fuel to 0.5 to 1 turn out

    - AFR at Idle 11.9 to 12.2.   Cruze 12.5 and WOT 12 with transition 12.5 to 13.4

- adjusted idle down from 1400 hot to 900 hot

Rear Suspension

Drivers' Rear shock was leaking fluid so I started to investigate.  Once I removed the boot carpet and floor I was able to access the top of the shocks. 

There were no identifying marks on the original shock/coilover.

I removed both coilovers and the shock was completly empty of fluid and pressure.   The passenger side has minor leaks starting.

decided to replace both as they were sealed units and not rebuildable. 

Decided on QA1 DS502 with 17 inches extended, 14.5 ride and 11.6 compressed.  With the 125lb spring, this should be more effective than the stock 104 lb with 12"x 2.5" spring

18 position adjustable for compression and rebound. 


ordered from Summit Racing

Installed and adjusted to softest setting.   Next year I may select a softer spring that is 10" long to allow for additional adjustment.  possibly 115lb for 10" spring
