Build 1FZ-FE TRD S/C Rebuild

I pushed the fitting through the back side and was able to clean it up with an exacto.

Wiring up next…

After a little interlude of having to do a manifold, plenum, and water pipe gaskets along with a heater control valve on my daughter's 96 4Runner, I went to move the 80 to get back at it to find a dead battery. Put the charger on it for the night. Need to check the new amplifier as I'm not sure it's turning off.

In the meantime, my son and I installed the relay, fuse, power & ground. We wired the pump, grounded the level sensor, and ran the switched power into the dash.

Next, is to connect the switched power, dash lights including a long wire run from the tank, and the boost pressure switch. And of course adjust / add methanol AND enjoy!

Wiring was not too bad. A little tedious. Used marine grade heat shrink connectors under the hood and made a plug under the dash for the light display. Trying to wrap most of it up. Not sure how I want to mount the boost switch.

Happy 4th everyone! The 80 is back on the road. Fun to be driving it again. Curious @cruiserdan if you have a scan tool to watch the timing curve. I'm curious if the max timing while driving is 40 degrees as seen in this thread:

Thread '1FZ FE Ignition curve'

Jun 19, 2017

Hi
Wondering if anyone knows the stock ignition curve, or a good designed curve, degrees at different rpms for this engine. I know it is adjusted by ecm but there should be basic curve data. With my scan tool I have seen it anywhere between 4 and 38 degrees while driving.
I need it as I am running engine analyzer software to help design my build
1FZ engine building and blueprinting
and it would be more accurate as without it program sets timing and fuel for best power but its not real world driveable and has high knock values. So far I have put in all the stock info, including cam...

With my aftermarket cam grinds I'm watching parameters closely to see if these are better but it is definitely pulling hills unlike before.

Did a test drive today up a pass considered by my machinist the perfect hill for an engine break in. Parameters: Around 85 degrees outside. 3 degrees base timing & 91 octane. Running a step colder plug. No pinging noted.

Manually tested the system using air pressure to confirm operation rigging up a vacuum/pressure gauge and a multimeter. Turning the screw out lowers the boost it kicks in at. Snow recommends half of total boost. Initial setting at about 2 psi but I’m thinking this might be a little overkill and I’d like to run a smaller pulley. The LED is handy to know when it’s operating.

Mine is OBD1. Never tried to read that. You need a proprietary breakout box to do it. Back in the day that tool cost the dealer over 4 grand (early 1990s dollars)

The beauty of my ultra gauge is I can look at lots of stuff with OBDII like timing, fuel trims, etc.
